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 2" x 3" steel tubing to connect the 2 Timbren suspensions together using the built-in hole on each unit.


Ground Clearance

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" x 3" holes make it easy to reinforce your trailer's frame by adding 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.


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

Components

  1. 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.
  2. 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.
  3. The trailing arm and integrated hanger attach the suspension to the side and bottom of the trailer frame.
  4. The control arm carries the spindle and the hub. It pivots on strong, long-lasting urethane bushings that never require lubrication.
  5. The EZ lube, 4" lift spindle (straight model shown) is simple to grease. If damaged, it can be removed and replaced, saving you both time and money.
  6. The hub is not included with this model.
  7. The built-in hole accepts 2" x 3" tubing. If there is no crossmember above the suspension, you can easily add support to your trailer's frame by inserting 2" x 3" steel tubing through the hole on each suspension unit and then bolting the tubing into place.

Timbren Axle-Less Suspension versus Leaf Springs

Leaf Spring Example

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

Torsion Axle Example

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.


Install Option 1

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 x 3-inch rectangular 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).


Install Option 2

The second option for installation is to fabricate an inboard extension plate that attaches the trailer's frame to the Axle-Less suspension.


Install Option 3

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.


Measuring Diagram

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).

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)

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.

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.

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


I am not a mechanic so Brandi was real helpful. Had to get some professional help to remove the old suspension and install the new suspension. The only drawback we ran into was the spindle did not extend out far enough to mount the tires in the normal way. We had to put the tires on backwards. It all worked out beautifully. Towed the trailer for over 1700 miles without any problems. Brandi was delightful to talk with and very patient with me. Her help was most appreciated. Sorry, I didn't take any pictures.

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!


Comments
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


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


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!

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


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.

    In regards to the Timbren Axle-Less Trailer Suspension Systems, the density of the springs and spindles will both be different between models as well as the design of the brackets if there is any sort of built-in rise or drop. These components aren't interchangeable so you'll have to upgrade to a new system if you require a higher weight capacity. The part # TASR5200S03 has a 5,200 lb capacity with built-in 4" lift.

  • Can Timbren Axle-Less Suspension Replace Standard Axles On A 36 ft Keystone Montana 5th Wheel?
    Yes, the Timbren Axle-Less Suspension system can indeed be installed on your 36' Keystone Montana 5th Wheel as they are a universal fit item that bolts directly to the frame of your trailer. To determine which Timbren option is correct for you, you will need to determine the axle rating of your axles. The easiest way to do this is by looking for the axle rating stamped on the axle tag on the center of the axle, or if this tag is missing you can find the GAWR on the same sticker as the...

  • What Replacement Spindle do I Need for My Dexter Torsion Axle?
    Based on the brake flange in your photo, even though we do not know exactly what capacity you have, it is at least 5,200 pounds. Unfortunately, with torsion axles like the one in your picture, you do need to replace the whole unit. This is because if you try to weld on a new spindle, the rubber on the axle can melt/become ruined. Therefor, I recommend purchasing a new unit like the Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03. If...

  • Required Negative Offset to Fit Oversize Tires on Timbren Axle-Less System ASR5200S03
    The Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03 is going to be your only option from Timbren to replace a 5,200 lb axle and have the 4" drop. Unfortunately there is no option for a different spindle for larger tires at this capacity. The distance from the hub face to the trailer frame with these installed is going to be 6-11/16". You will want to check for your particular tires since it varies but it looks like the section width...

  • What Tire and Wheel Size Fits Timbren Silent Ride Suspension TSR10KT02
    Timbren Silent Ride Suspension # TSR10KT02 is designed for 3 inch axles and those are usually rated for 6,000 to 7,200 pounds. So basically provided the tires are an appropriate size and capacity for the trailer you will be able to use them. On the low end (6,000 pound axle) that would be at least a 235/80-16 tire size. And on the higher end it would be a 235/85-16 or larger. I have included a link to all of the 16 inch tires, wheels, and tire and wheel combos we carry.

  • Stainless Steel Disc Brake Kit Recommendation for Use with Timbren Axle Less Kit TASR5200S03
    The disc brake kit you mentioned does not include hubs so for use with the Timbren Axle Less kit part # TASR5200S03 that you mentioned running two of the part # K1HR526DS would be your best option. This kit includes a Dacromet-plated hub-and-rotor assembly, as well as a stainless steel caliper and Dacromet-plated mounting bracket.

  • Timbren Axle Less Kit for Trailer that Weighs 3,045 lbs
    Since your trailer weighs 3,045 lbs when loaded the 3,500 lb Timbren Axle Less kit part # ASR35HDS05 would be perfect unless you though you were going to eventually loaded down beyond 3,500 lbs. Then you'd want the # TASR5200S03 which has the higher 5,200 lb capacity. If you end up with too high of a capacity your ride quality might be a bit rougher.

  • Replacing Existing 3500 lb Axle With a 5200 lb Axle
    When replacing a trailer axle, the spring seat spacing isn't super-critical because you can always relocate those by obtaining new spring seats and having them tacked into place where you need them. The hub face to hub face distance is what's critical. What's the hub face dimension of your current axles? We offer 5.2K axles in the 3 most popular lengths (hub face to hub face) of 86-1/2 inches, 89 inches or 95 inches. • 86-1/2 inch E-Z Lube axle, part # 8327816 for the axle only or # 8327816-EB...

  • Timbren Axle Less and Hub Recommendation for 8 Lug Bolt Pattern and 4 inch Lift
    The 8 lug bolt pattern you are looking for is only available on higher capacity hubs than 3,500 so the parts you mentioned Timbren kit part # TASR5200S03 with hub part # 8-231-50UC1-EZ are exactly what you need for the added ground clearance and bolt pattern.

  • Recommended Replacement Axles for Old Dexter Axle #11 5,200 lb Torsion Axles
    I reached out to my contact at Dexter Axle who said that based off of the numbers you sent in it sounds like you have a #11 Torsion axle rated for 5,200 lbs that is on a Haulmark Trailer manufactured back in 2001 (at least the axle was). Your axle should use 6 lug hubs with EZ-Lube spindles and that it has a 95" hub-face measurement with a 75-3/4" outside bracket measurement (which would be equivalent to spring-center). The closest thing that we have to this is the Dexter Trailer Axle...

  • Hub and Drum Compatibility For Timbren Axle-less Suspension 5200-lbs
    If you're going to use the Timbren Axle-less Suspension System 5200-lbs with brake flanges installed, like the 2" lift model # TASR5200S05 or 4" lift # TASR5200S03 , those are compatible with the Trailer Hub and Drum Assembly - 5.2K and 6K E-Z Lube Axles - 12" - 6 on 5-1/2 - Pre-Greased # AKHD-655-6-EZ-K since they have compatible inner/outer bearings, races and grease seals.

  • How to Raise an Enclosed Trailer with 5,600 Lb Axles
    In order to raise your enclosed trailer I have a few options for you. The first option as you mentioned is to switch to an axle-less system that has a lift kit. We do offer these but the issue you are going to run into is that the highest rated one they have with a lift is the Timbren Axle-Less Trailer Suspension System part # TASR5200S03 which is only rated at 5,200 lbs. If this will work for you then in order to see how much it will lift the trailer you will need to measure from the bottom...
