The heavy-duty Timbren Axle-Less system combines Timbren's standard 3,500-lb Axle-Less system components with 2,000-lb AEON rubber springs, giving you a suspension system that is perfect for your small, off-road trailer. It allows you to use parts that would typically only fit a larger trailer on your undersized trailer. Add brakes for improved control. Get greater ground clearance and increased durability by installing bigger tires and wheels. The drop spindles deliver lower ground clearance than you would get with a standard straight spindle so that you can easily load and unload equipment. This makes the heavy-duty Axle-Less suspension system ideal for off-road use.
Note: The Timbren Axle-Less suspension system may require additional support on your trailer. If your trailer does not have a crossmember above the spot where you want to install the Timbren system, you may need to reinforce the frame. You can accomplish this three ways. First, you can retrofit the trailer with a crossmember. Second, you can build out the trailer frame. Third, you can use standard, 2-inch steel tubing to connect the 2 Timbren suspensions together using the built-in square hole on each unit.
Ride on rubber with Timbren's Axle-Less trailer suspension system. This one-of-a-kind suspension consists of two separate units, each containing rugged steel arms and two strong, hollow rubber springs. Overall, the system safely and effectively absorbs road shock, minimizes trailer bounce and rattle - regardless of load size - and helps to protect your trailer's components and cargo. Built-in camber and toe-in keep your trailer tracking straight to minimize tire wear. Integrated hangers attach to your trailer's frame. And 2-inch holes make it easy to reinforce your trailer's frame by adding standard, 2-inch-square steel tubing (if needed).
The Axle-Less independent suspension system replaces your trailer's existing leaf spring suspension and can eliminate the need for an axle. The independent action of the suspension reduces roll when your trailer is cornering and allows you to maximize ground clearance and minimize deck height. Your trailer can have the same side-to-side clearance as your tow vehicle. And the low deck height makes it easy to load cargo from either the rear or the side.
Because you're riding on rubber, your trailer will ride smoothly and comfortably, whether you're navigating rocky terrain or highway asphalt.
Timbren Axle-Less Suspension Parts
- The AEON progressive-rate main spring supports the weight of your trailer and cargo and easily absorbs road shock. It is constructed of heavy-duty, hollow rubber.
- The rebound spring minimizes trailer bounce, rattle and bottoming out. It keeps the suspension under constant tension and ensures that the main spring compresses and expands in a controlled fashion. And it delivers a smooth, stable ride - regardless of how much cargo is on the trailer.
- The trailing arm and integrated hanger attach the suspension to the side and bottom of the trailer frame.
- The control arm carries the spindle and the hub. It pivots on strong, long-lasting urethane bushings that never require lubrication.
- The EZ lube spindle is simple to grease. If damaged, it can be removed and replaced, saving you both time and money. The spindle also includes a 4-bolt brake flange for simple mounting of trailer brakes.
- The hub is not included with this model.
- The built-in square hole accepts standard 2-inch tubing. If there is no crossmember above the suspension, you can easily add support to your trailer's frame by inserting 2-inch steel tubing through the hole on each suspension unit and then bolting the tubing into place.
Timbren Axle-Less Suspension versus Leaf Springs
The Axle-Less suspension's progressive spring is a definitive upgrade over leaf springs. Although leaf springs deliver a stable ride when supporting a load, a trailer with leaf springs will bounce and rattle when it's empty or supporting a light or off-center load. On the other hand, your trailer can bottom out on bumpy roads if the load is too heavy. The AEON progressive-rate springs of the Axle-Less suspension always deliver the same reliable performance, no matter the load size. As more weight is added to the trailer, the springs compress and become stiffer, offering more support for heavy loads. And because they rebound more slowly than leaf springs, the AEON springs do a better job of absorbing road shock, thereby keeping your trailer from bouncing and rattling when you're carrying a light load. So with this versatile system you will enjoy a smooth ride whether you're towing an empty trailer or a hefty load.
Unlike leaf springs, Timbren's Axle-Less suspension units operate independently of one another. Each spring activates only when needed. This reduces roll and delivers top-notch performance, even when you're hauling off-center loads. When your trailer with leaf springs takes a turn, one side of the suspension compresses and takes on more weight, and the other side becomes looser and bounces. This causes rattle and can make the trailer lean to one side. But when your trailer with the Axle-Less suspension takes a turn, one side compresses and becomes more rigid to absorb the weight, and the other side expands to normal height to help steady the load and minimize bounce and rattle. The load stays better balanced, even if it is off-center.
Timbren Axle-Less Suspension versus Torsion Axles
Timbren's Axle-Less trailer suspension system is a great alternative to torsion axles. While both systems allow either side of the trailer's suspension to operate independently, only Axle-Less suspensions are actually separate units. Torsion axles still require a bar that spans the bottom of your trailer, whereas Timbren's system can eliminate the need for a thru axle - giving you the same amount of ground clearance from the front of your trailer to the rear. It also allows Axle-Less suspensions to fit any trailer width - unlike torsion axles, which have to be fitted to an exact frame width.
Axle-Less suspensions operate in a smoother, less stressful manner than torsion axles. Torsion axles use a twisting motion, where the bar inside the axle tube rolls against rubber cords or a rubber wall to create compression and resistance. The up-and-down motion of the main spring and the side-to-side motion of the rebound spring in Timbren's Axle-Less suspension work together to provide smooth, consistent compression - with no twisting - that results in a better ride and less stress on the suspension's components.
Installing the Timbren Axle-Less Suspension
Whether you are building a trailer or retrofitting your existing trailer with the Axle-Less system, you must make certain that the trailer's frame is both perfectly square and sturdy enough to support a heavy load without the aid of a thru axle.
There are three ways to install the Axle-Less suspension. The easiest method, which is recommended if you are replacing axles on your trailer, is to install a piece of 2-inch-square tubing (sold separately - available at most weld shops) through the integrated hole in the Axle-Less suspension. Then all you need to do is bolt the suspension to the side of the trailer's frame with three bolts (not included).
The second option for installation is to fabricate an inboard extension plate that attaches the trailer's frame to the Axle-Less suspension.
The third method of installation is to bolt the Axle-Less suspension's hanger to the trailer's frame and to an existing crossmember that is in the area where you want to install the suspension.
With both the second and third options, you must use three bolts to attach the suspension to the side of the frame. And you also have to use two or three bolts to attach the suspension to the bottom of the frame extension, or crossmember. Both the second and third methods of installation will eliminate the need for a thru axle and provide the most clearance.
Timbren's Axle-Less suspension units should be installed directly across from one another. Before mounting the units, measure back from the coupler and mark the frame to make sure that the two distance measurements (A and B) are within 1/8 inch of each other. Then you can drill holes through the frame and attach the hangers with Grade-5, half-inch bolts (not included).

Video Transcript for Timbren Axle-Less Trailer Suspension System Installation
Today we're going to be taking a look at, then we'll show you to install the Timbren Axle-less Trailer Suspension System. These are available in multiple configurations to fit most applications. Just check our website out for details. Today specifically we're going to be using part number ASR3500S05. This is a spindle only configuration for 3,500 pound axles. With the spindle only configuration we're going to be reusing our bearings, we're going to be reusing our brakes and our drums.
You may want to pick up some new seals if you're going to go this route. We also have the full kits available with the brakes, the drums, and everything that you'll need. The Timbren Axle-less Suspension is an excellent, excellent product. You can tell an immediate difference as soon as we start hauling our trailer with the items installed. It's much, much quieter, much smoother, you don't feel the weight in the truck nearly as much as you did with that standard suspension. You can see as we're cornering there's no transfer of weight.
They're working independently to keep our trailer nice and level. Here's what our kit's going to look like installed. This axle-less suspension system from Timbren is kind of a solution for all that noise and everything that we typically get with our trailers; real rough ride. Now, they use 2 rubber springs essentially, they're Aeon rubber springs. We've got our larger one here in the back. This is the main body of the system, and as we load it more and more and more it constantly kind of adapts to that to give us just the ride of support that we need. To keep this constantly under tension so we don't have to ever worry about a lot of that rattling and stuff, we've got a rebound spring right here in the front.
These are designed to work with really any style of trailer frame, no matter of the thickness here. Depending on the application if you've got a really wide trailer, well then you're just going to put the 3 bolts in the side, 3 bolts up through the bottom. We're dealing with a little bit narrower angle channel here, so what we've done is we've put the square tube across the front. You could also design a bracket to go on the side, if you wanted like a gusseted bracket. There's a lot of options out there. We went with the spindle only design.
It's really heavy duty, too. You can really tell about the quality that they've put into the design of it. Going to have a black powder coat finish on all of our surfaces and this real nice thick steel fully welded around all of our points with reinforcement gussets right where we want them. You can just tell it's a really well built system. Another advantage that we're going to see with the axle-less suspension is going to be increased ground clearance. We don't have that axle that typically hangs down here lower. Even with us using the cross tube design or the cross bracing design, it's tucked up right underneath of our trailer. It's even up higher than what our cross members are here for our flooring, so really tucks it up. Then this area down here, you can see smooths off. The axle-less suspension system can also help us with getting our deck height of our trailer where we want it. These are available in both drops and lifts. One of the added benefits that we get out of this axle-less system is that we're not tying this side of the trailer to that side of the trailer with one of those through axles that are going to go right through down here where all our movement's going to actually take place. This allows these to work independently of one another. If we hit a bump on that side it doesn't transfer all the way over here and then cause this side to go too. Now, they've set this up with tow and camber adjustments aligned 00:04:02 already, so we should have great tire wear as we track down the road. However, if need be they do provide us with some nice alignment shims here if we do want to change it up a little bit, or maybe our trailer's frame wasn't exactly square. Another great thing about the Timbren Axle-less Suspension set up is that they use urethane bushings here at our pivot point. It's going to be very very long lasting. It's going to keep everything nice and tight, and we don't have to worry about lubrication. To begin our installation we need to get our factory axle out. Now if you are going to reusing hardware off of the original axle it's best to do it when it's still on the trailer. That way you're not fighting the roll. All right, now you'll notice here on the frame of our trailer, this is our rear spring perch. We've removed the front to allow room. You may have to do that on yours, and there was a couple welds here and then here that kind of stuck out on the frame rail. We've gotten rid of those. Just use a grinder, get it nice and clean. We want a nice smooth surface for this to mount up against. We're going to mock it up now just by bringing this edge up and letting it sit on our trailer. You can see the 3 holes we're going to use for attachment. Now the key to getting this set up properly, you can see we've got some plumb bobs here. Basically it's just a string with a nut tied to the end of it. We've gone off of both of our spindles here in the same location, and then we've gone from the center of our coupler in the front so we've got them at 3 locations. Now we're going to measure from that string back to this string, and then we'll measure from the front over to the other side. It's very important for us to have these within an 1/8 of an inch. What this means is that we've got the perfect triangle from the coupler back to each of our spindles. We won't have to worry about any kind of side tracking. It's going to keep our trailer running straight behind us, and it's going to make sure that we're getting proper tire wear. Adjust as necessary. We want to make sure if you're using plumb bobs that your trailer's level. After that it's just a matter of getting them lined up to where they're going to be just right. We'll measure, mock it up, measure, mock it up, and then once we have it right where we want it we can get our holes drilled. Now we want to take a punch and I'm going to mark the middle of my rear hole. Then we can start stepping up to a 1/2 inch hole diameter is what we want to end up with. We start with just an 1/8 inch and then kind of move up as we go. All right, that created a little too much movement, so we want to get this hole drilled perfectly to get that suspension out of the way and get our hole drilled out. We'll bring it up, slide our bolt through the hole there, and then put our hardware on the inside. That's going to do a good job of holding that in place while we get the rest of our holes marked. I'm going to use a jack stand again here just to apply some upward pressure. I'm going to tighten this nut down temporarily. That's going to draw it right over into position we want to make sure it's pressed up firmly all the way in the front. We don't want any kind of gaping between the top of our enhancement here and the bottom side of our trailer. Now we can use our center punch or our 1/2 inch bit here and get the center of our holes marked. You see I've already mocked up what would be the passenger side of the trailer. Anything I do on this side, I'll do the exact same thing on the other side. Now we're ready to get these pulled down and we'll get our holes drilled out. All right, now with those holes drilled out let's get our suspension back up into place here. What I want to do is just get these 3 started and I'm going to get them snugged down. This isn't a permanent mount, so we don't want to torque them all down. We've got to measure for that cross tube. We're going to be using this opening here for a 2 inch by 2 inch cross tube section that's going to give us additional strength. There's a few options on the additional strengthening process that you can check out in the instructions. That's mainly for just like the trailer that we've got here, just your simple utility trailer that just has an angle iron frame. If you see channels and things like that, typically once we're putting these on the heavy-dutier trailers there's going to be plenty of thickness in the frame. You really don't have to worry about having that cross tube. Now to figure out how long of a pipe that we're going to need here we're just going to measure inside to inside. There's going to be a couple little lips there. Right here there's a little bit of a lip. We just want our pipes to sit just inside of those, and we'll want our square tube to fit right inside of that. Now with our pipe cut to size all we'll need to do is slide it in all the way across, and we'll want to make sure that it engages our other side as well. All right, that's held in place there kind of by those little lips we saw in each end. We need to get our bolt holes here marked so we can drill our holes and install our hardware. Those should be marked so let's pull our tube back out of there, get those holes drilled, and we can put it back in. Now we can get our center punches taken care of here. Just like before we'll just step up our bit size as we go, makes it a little bit easier. Now with the tube back in we'll take our hardware, got kind of a tight squeeze here but we're just going to place that through. Place that flat washer inside of there on the bolt, then we need to get our nut started. One of these little flexible magnets is a really good way that bolts quite a ways back in there. If you've got a different method that works for you, great. My fingers won't reach in there. Maybe a pair of needle-nose you could get to work in there. These little magnets are pretty readily available and pretty handy to have, so that would be my recommendation. We'll just leave that one loosely installed. Now we're going to take our other bolt, we want to place it through both of our holes but we don't want to have it poked all the way through. What we're going to do is have that stay there as we get our spindles torqued down, as we get our brackets to our frame torqued down. Then we'll torque down our inside bolt, then we'll be able to get to this and torque this down. We'll just at that point either thread it in by hand or with a wrench, put our stuff on it and get it torqued. If we we're to leave this out completely so we could get to that back bolt, it's likely that our holes would then be slightly misaligned and it would be real difficult to get it in. Now we want to look in the instructions and find our torque specifications and we want to go through and torque everything down in the appropriate order to those specifications. I had these pretty snug when we we're doing the install just so we wouldn't have to worry about any movement or anything with the spindle. With those done we'll move up to the 3 here in the side. Once those are properly torqued we'll go to the ones that we've got inside of our tube. With everything torqued down that's really all there is to the install. I would here on this cut piece of tubing, just a little bit of black spray paint there. Just kind of seal that up, prevent any rusting there. Then, depending on your set up if you're using, if this is on a braking axle then you'll put your brakes back on your flange and then rebuild your hub per the instructions. If this is on a lighter-duty trailer and if you don't have brakes then you're just going to rebuild your idler here. Good time to replace the seals, repack the bearings, inspect those bearings, or just order a new kit to fit right on here and then you'll know you're going to be safe as you go down the road. All right, now we'll lower it down until the tires touch the ground and you'll want to be sure to use a torque wrench and get all of your lugs torqued down appropriately. That's going to complete our look at the line of the Timbren Axle-less Trailer Suspension Systems.

Atrocious packaging! Timbren should be ashamed of how they're sending this stuff out - packaged with flimsy paper and nothing else. Not surprisingly, the spindles arrived damaged to the point where replacements are being sent, and the main arms have big sections of powder coating missing from where the rattled around in the box.
On the flip side - Etrailer has been awesome to work with and will be sending out replacement parts. I'll update this post after the parts arrive
by: Joe11/29/2018
Just receiving my parts, to start with box's got beat up (have no suggestion), Packed very well good tape (use more around center will add strength), the lay out will begin in a week or so, thank you, p.s. shipping time was Awesome

Review from a similar Axle-Less Suspension in Trailer Axles
The trailer rides great down the road and no more worries about saltwater and rusty leaf springs. Not a cheap option but I’m very happy with the setup. When installing, just be sure to measure accurately and have sharp drill bits. A drill press type of guide also helps ensure correct drilling angles. The first picture is of a mounting gusset a local welding shop made. One is needed for each side and necessary to provide needed mounting strength-at least on my trailer frame. Pics 2 and 3 show the mounted suspension on one side of the trailer. Pic 4 shows the suspension on one side of the trailer with the axle attached and a separately purchased disc brake assembly mounted on it. Finally, pic 5 shows a 2” box channel between both suspension assemblies. Independent suspensions would have been nice, but I wanted to ensure trailer rigidity was maintained. So, after one year, so far, so good. It’s all smooth sailing down the highway.

Actually over a year, and still working great.

Review from a similar Axle-Less Suspension in Trailer Axles
I installed these on my single axle travel trailer to replace the axle and leaf springs. Weight savings was a wash with the required steel tube for added stability. I installed on an I-Beam using aluminum plate as a spacer. It took my friend and I 3 days to install everything. The hardest part was rerouting my black pipe propane line. I also had to install it just back of center due to a steel cross beam being in the way of the middle bolt hole. I replaced the brakes and hubs as well as the wheels to match the new hubs.
Overall we've been super happy with this upgrade. The trailer rides a lot smoother. I'm not finding random screws on the floor after a long bump ride.
We decided to do this after our leaf spring broke 2 times, 12k miles between. We were done dealing with a subpar suspension. I probably would not recommend doing this if your leaf springs are working for you. We put a lot of miles on our trailer. We aren't weekend campers.
Comments
1 year later still working great! Very happy with the performance. We have driven at least 20k miles with these springs and have not had a single issue. I also am happy I upgraded weight limits on everything.

Trailer suspension and disk brake performance is outstanding big big difference over leaf spring and electric drum brakes.
Installation required modifications to the frame to monut the timbren suspension
Comments
The Timbren axle less suspension and Disk brake and disk brake controller system is still work great. will never go back to drum brakes or leaf spring axle suspension.

Review from a similar Axle-Less Suspension in Trailer Axles
Incredible system. Handled our Overland trek through Colorado and Moab. These axles on our 1917 Ford bed ran multiple Jeep Badge of Honor trails. The suspension handled flawlessly. Handles off camber rocks and drop offs smoothly. We ran the 4 inch lift and off road offset to fit the factory Jeep wheels.

Actual trailer weight 1540#, 210# tongue weight. 1310# suspension load. After 600 miles, both springs collapsed making the suspension rigid. Have received replacement springs from Timbren but haven't had a chance to try them out.

Review from a similar Axle-Less Suspension in Trailer Axles
The axle-less suspension worked very well for my boat trailer. The suspension was easy to attach to the trailer frame and provided a lower profile than the traditional leaf spring and axle system.

Review from a similar Axle-Less Suspension in Trailer Axles
They have more pros than cons, but the second set I bought broke the flat plate that holds the spindle at about 8 months. The steel quality seemed less than I would expect since it basically peeled it back like a pop can as you can see in the pictures. Otherwise I like the clearance and ride. They last 2-3 years where the torsion axles I replaced would wear out in 4 months after driving down rough gravel roads. There is a grade zerk on the underside which I didn't realize until I bought the second set. That would have helped the first set last longer had I known about it.

Review from a similar Axle-Less Suspension in Trailer Axles
I used these axles in a different way than most would. I needed a trailer that was small, could handle tight switch-backs, carry 600 lbs and be light. I had this idea and as a retired design engineer I saw a great possibility in this axle. I have made four of these trailers now, one as a camp trailer, 2 for trail work for State Parks and one as a utility trailer.

Review from a similar Axle-Less Suspension in Trailer Axles
Purchased 2 sets of the Timbren 1200 Axle-less systems for upgrading the suspension on an older 30' ft glider trailer. Single axle with small (13") tires made towing tough due to porpoising, dragging on drive entrances do to poor flotation; also German made and metric, no repair parts. GVW 2000 lbs equated to bouncy ride.
Dual sets now allow the trailer to ride over bumps and sharp inclines easily, smoothly, little bounce on country roads; porpoising is history. My glider now rides securely, safely, quietly.
Install time 4 1/2 hours (includes head-scratching). Results are outstanding, units are totally solid. Recommend the square tube interconnect, easy and quick - trailer frame was on the light side, so a precautionary fix. Clean look underneath.
Ordered 5 wheels w/tires, very nice.
Helpful neighbor so impressed he ordered a HD single set for his new DIY snowmobile trailer.
Customer satisfaction 100%, from phone order, online support, product information, immediate shipping, install instructions, followup... HIGHLY RECOMMENDED!

I have just a little more to add regarding my purchase: Two sets, of the Timbren Axle-less assemblies, 1200 lb, and 5 wheels. I placed the order via phone, and whoever was on-call that day provided great answers and recommendations regarding the units, wheels and tires. At 31 feet, the trailer originally exhibited amplified porpoising on any bumps or dips in the road. Also bouncing and occasional sideways tipping due to the single axle. It made a lot of noise on my mountain community washboards. I speculated that the Timbren units would solve most, if not all of these problems and they have. Installation on my older 31 ft European ie, metric and no longer manufactured glider trailer was a mere 4.5 hours from removal of the old single axle to setting the trailer back down on its new assemblies. Instructions are complete, precise, useful and helpful. Appreciated. Little to comment on as installation was all straight-forward. I would like to describe the maiden voyage to the airport and back, but there is nothing to tell, other than it towed beautifully proper alignment instructions, and all that I viewed from the rear view mirror looked like a magic carpet ride. It rides over washboards and pot holes like a marathon hurdler, the 4-wheel independent suspension is great. Packaging: the shipping boxes all arrived in good condition, but the cardboard component boxes inside them... not so much. Most were ripped and open due to heavy components lightly surrounded with brown packing paper, just token amounts. Parts: all was accounted for minus a pair of spindle axle washers for one set, easily replaced at the local farm and ranch supply. No squawk, just an fyi. I am very pleased with your product and support, and was happy to leave a 5-star review with photos. The upgraded suspension was also a topic this past weekend at the glider port by those who regularly trailer their ships to various soaring events, some as far as a thousand miles away. My compliments to eTrailers, hope you can use my info,

Review from a similar Axle-Less Suspension in Trailer Axles
Pleased with ETRAILER, will order here again. Not as happy with the torsion axle setup. 2 inch square opening for tying both axles together with your own 2" square tubing are not shaped to match 2x2x1/8 tubing. Grinding and welding of tubing required to make it fit. Also found the overslung stub axle left the end of the pivot arm without much ground clearance though the unit was intended and spec'd for atv tire off road use. A pivot arm with mounting pads top and bottom would be better and allow the user to choose high or low clearance use. I found the units were perfectly suited to offroad use once I fabricated new mounting pads and welded them to the bottom of the arms.
Comments
After a year of off road use, I couldnt be happier. My trailer rides smooth loaded or unloaded. No of that bunny hopp with leaf springs or rigid mount axles. The small rebound control snubber works perfectly! I modified my components for high clearance but the concept is sound, they work well. Great job Timbren!

I rebuilt a 4 x 8 trailer using the Timbren Axle-Less Trailer Leaf Spring Suspension and it works great. I would recommend it to others.

It is important to know that your wheels are going to sit very tight to the trailer frame. I needed to add an extension to the hub for it to clear the sides of the camper I built.

Review from a similar Axle-Less Suspension in Trailer Axles
It was a very straight forward install, it goes pretty smooth if you take your time, double check your layout,
Make sure of your bolt sizes (length) before going to the store. If you plan the project, don’t rush, its not a race, it goes really good. I spent about 10 hours spread over two days by myself. I am just waiting for tires to arrive.
All that said very happy with the product and etrailer. Will recommend for any axel/suspension replacement.
Comments
Things have worked out well, can hardly tell there is a trailer behind the ATV very smooth ride almost no noise, vert satisfied.

Review from a similar Axle-Less Suspension in Trailer Axles
Very exicited about these axels, I have been eyeing these for over a year. (Excellent service from etrailer, they had my parts to me in 1 day from the time of placing the order.) These axles seem to be well made and fit nicely with the Dexter hub and drum assembly and the 12" electric brake kit. I installed this all on a M1101/M1102 trailer frame after removing the factory axel assembly. I have not ran these on the road or off as of yet but will give another review at that time. The fit and finish are great and the packaging was good, a little banged up from shipping (missing 1 washer)

Review from a similar Axle-Less Suspension in Trailer Axles
These units install easily, are well made, and perform great! The trailer doesn't bounce around like you see a lot of trailers do while traveling down a bumpy road. I traveled some unpaved roads with no issues. I am certainly glad I went axleless. I installed with 15" tires. Problem is I didn't go big enough.
I intended to install on an existing trailer that I had. Changed my mind and built a new trailer. The new trailer came in heavier than I had planned. 2k pound capacity is now too small. I have to watch what I load the trailer with so I don't over load the suspension. I intend on buying the 3500 pound units when I have the money.

Review from a similar Axle-Less Suspension in Trailer Axles
Timbren saved our RV road trip! The leafs on the axle on our 2018 Jayco TT came apart while driving in Maryland. We tried going to the manufacturer, but they were useless. Going to a RV mechanic meant being grounded for at least 2 months. Then we found Timbren. With the help of Timbren's excellent staff we purchased axle-less system through etrailer, who made sure we got as quick as possible. It came ahead of schedule, my husband installed the Timbren system and we were back on the road! The axle-less system is better than the original manufacturers. If you plan on taking your RV or TT farther than 100 miles GET THIS INSTALLED and get it through etrailer.

Review from a similar Axle-Less Suspension in Trailer Axles
The order came in on time and the customer service at etrailer.com (Ashley) and Sean from Tmbren was outstanding. They both were very helpful in my choosing the right product for my needs. The axle less suspension's performance is absolutely superb. It vastly improves ride quality. I am using it on a teardrop camper that often goes on gravel roads and the raddling sound from the leaf axles was horrible. A couple of points to consider before you settle on the axle less suspension: keep in mind that you will lose some hight of the trailer. While you will gain clearance from the lack of the axle, the suspension will make the trailer sit lower than before.i had to lower my hitch by an inch to maintain the trailer leveled. Also it does appear to compress at higher rate than the leaf springs, which makes it softer but easier to reach it's limit. Overall this product is absolutely a must if you are looking to improve the safety and the quality of your towing.

Review from a similar Axle-Less Suspension in Trailer Axles
enclosed are pics of trailer and spindle units. I was very happy with the end result,
lowering ez loader trailer 8 inches for hovercraft. the spindle units were well made,
very strong but had some weld repairs as pictures show.i could not set the needed
adjustments till I cleaned up the units with a stone and file. also please improve the
packaging . these heavy units need something better than cardboard for shipping.
they were dislodged from Styrofoam and partially poked holes thru cardboard. but
fortunately no damage there. again im happy with the installation.thank you!!!

Review from a similar Axle-Less Suspension in Trailer Axles
After a great deal of research, I ultimately chose the Timbren long arm kit to replace the torsion axle under my teardrop trailer. My initial impression is that there is simply no comparison between the two. It now rides better, pulls better and handles better than I could have imagined. The Timbren axle system is incredibly well built and is much more confidence-inspiring. While the spring rate closely matches my trailer weight, the components are much more rugged and robust. The spindles, bearings and brakes are rated at double the capacity of my old axle which gives me great peace of mind. I pull my trailer, both on and off road, anywhere it will fit and the long travel and heavier components are a game-changer for my travels. Installation, while requiring a bit of forethought, was otherwise straightforward and methodical. Documentation available from etrailer and Timbren, is second to none. Instructions were clear and concise with drawings and detail taking the major guesswork out of the equation. Even though, due to the odd frame design of my trailer that required a bit of work to adapt, I ended up making some frame stiffeners, the adaptation was as simple as it could possibly be. I've ordered from etrailer in the past and they were 100% accurate on this order as well. I ordered the Timbren kit without backing plates and hubs due to the requirements of my trailer and etrailer suggested, explained availability and supplied all of the components I needed. They truly a stress-less bunch of folks with an extraordinary website. I'll no doubt turn to them again...

- Timbren Axle-Less Suspension Recommendation for M1101 TrailerFrom my available specs on your M1101 trailer, it has a maximum vehicle weight of 3,400 pounds. It also looks like it uses off-road tires. With that capacity and tire type, we only carry 2,000 pound Timbren Axleless systems that are compatible with the 5 on 5 bolt pattern you need. That is the # ASR2KHDS09. The hubs that go along with this are the # 84556UC3-EZ. With this system, you will be limited to a 2,000 pound weight capacity. As far as brakes, I always recommend Nev-R-Adjust...

I attached a chart that you can use that explains how to adjust the axle on a trailer to make sure you have the correct tongue weight. As the article explains it can be adjusted depending on the tongue weight you get.

- Can Timbren Axle-Less Suspension System Work With Off-Road Tires?There is a 2,000 lb capacity Timbren Axle-Less Suspension with 4" Drop Spindle # ASR2KHDS09, though not a 1,200 lb one. I am not certain what you are referring to in terms of "strong enough" but it will work with 3,500 lb rated hub and drum assemblies # 84546UC3-EZ as well as 3,500 lb brakes. If you were referring to your trailer being strong enough, if you do not have a crossmember above where you want to install the Timbren one will need to be added, or you can reinforce your trailer's...

It has a weight capacity of 2,000-lbs and has EZ Lube spindles that make it easy to grease the bearings without having to remove the hubs. This system has a 4-bolt brake flange.
