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.


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-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

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 spindle 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 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

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-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).


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).

This was a major project for me. My Little Guy 5-Wide teardrop trailer had a failing Al-Ko axle system. I didn't want to try to re-create that mess, and so looked into Timbren. Too many choices! However, once I worked my way through the selections, I ended up slightly downgrading the axle from 2200 lb to 2000 lb. I've had no issues, and the ride is far, far superior to the original. Installation involved cutting away the original axle bracket, bolting the Timbren to the frame, and adding the 2x2 tubing between the 2 axle sides. This made sure it wouldn't rack--I was concerned the original frame was pretty lightweight. I measured many, many times to make sure I had the axle in the right place, and it worked out just fine. Ride is almost identical to the original axle. I would do this again, but maybe get a bit more lift next time. I have pretty tight clearance from the tire to the fender. They do make a different model with more lift. This is a very beefy axle system. Great company. Oh, and I had a little mixup when I placed the original order with etrailer. I was only shipped one of the two required boxes. A few emails back and forth, and they sent me what I needed. Thanks for taking care of me! 790385

A little bit pricey, at first. But in the long run they are cheaper. We used to bend or break an axle every 3 or 4 months. But we have had these a couple of years now with no problems. One thing that is nice is on a tandem axle set up you can get a flat and you just have to take the wheel off and run on 3 or 2 wheels without the hubs hitting the ground. 593458

Built a custom trailer to haul an ATV on some bad rural roads in Baja. I used the 2" drop axel-less suspension to allow for full size tires and wheels yet keep center of gravity low. Easy to install on exposed frame, but note that a required brace or 2" square steel bar may be needed and sourced on your own. The finish is not very durable and does not survive the normal bumps, wrench scrapes and scratches of installation; plan on some touch up once installed. Pay attention to the spindle clearance and wheel offset. 317250

I installed these on a small jeep style camping trailer that I built. I plated my frame and also used the suggested two inch square tubing to tie them together. It rides very well, looks like it should be very durable, it's a simple design, simple to install, more economical than other independent systems, has less parts to go bad than other systems, I would highly recommend to any body using a trailer on rough roads! 582196

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. 289894

Timbren Axle-Less Suspension - Spindle Only - Regular Tires - 5200 lbs Item # ASR5200S01 Looks great on empty trailer, idea is good, bad execution. When loaded tires "splay out" severely, excessive tire wear, obviously too much play in system somewhere. 584361


Comments
Excessive camber which causes wear on the portion of the tire tread closest to the trailer can be caused by a few different things. 1 The axle-less suspension system has a 5200 lb per set capacity, so youll want to be sure this amount is not being exceeded. 2 The surface of the trailer that the suspension member is added to needs to be an integral part of the trailer that should have NO give in it whatsoever. Any flexing of the side member there will throw off the camber of the tires. I have seen what you describe occur when the suspension system has been mounted to tubular steel that made up the edge of the trailer frame. In that instance, some angle iron was added to stiffen things up. 3 Its not required, but a piece of 2x3 inch tube steel of the appropriate length can be used as a beam connecting the two sides, utilizing the existing hole in the axle-less suspension member. This will help stiffen things up. 4 The suspension system should have included some shims that can be used where the spindle attaches to the suspension portion of the assembly. Using these shims can decrease the camber, but only if the points mentioned above are taken care of. Ive checked with Timbren regarding the above, and they concur.

So far great! I used one of the Timbren Axles in a mountain trail camp/SAR trailer I just finished building. I have only had the trailer on roads because all the trails I want to try it on are still under snow...but it is melting fast. I have included a couple of photos. 612696

Review from a similar Axle-Less in Trailer Leaf Spring Suspension


I was looking for a low profile axle system for my motorcycle trailer. The primary requirement was to be able to load my motorcycle by myself which required a low-profile trailer. With the 4" drop provided by Timbren, this setup turned out great. I originally intended on using ramps but after I swapped the leaf spring axle out with the Timbren, I found I was able to ride my motorcycle on/off without the need for the ramps. Originally, I was going to go axle-less but I found when torquing down the assembly to my frame it started to compress the aluminum rail. To take the pressure off the frame I added the 2" bar from axle to axle. Pulls smooth and effortlessly. I've had several people comment on the trailer height with one wanting to buy the trailer from me. This person worked at the local Honda Dealership. He thought it was a great design and I would imagine he's seen a variety of trailers come through his lot. The other option I considered was a torsion axle but I was looking for the lowest profile I could get. Therefore, cost was not a key factor. I also like the soft ride the Timbren system provides. Not sure if the torsion design would have been as smooth over bumpy roads. Regardless, I'm pleased with how this project came out. 352952


Comments
Its been a year since Ive installed the new axles on my trailer my comments above still hold true. Im very pleased with the ride quality of the system after a year. The trailer tracks true and has hauled many things other than my motorcycle. Even empty it doesnt hop around like the original stock straight axle did. No regrets on the purchase.

Review from a similar Axle-Less in Trailer Leaf Spring Suspension


I pull my Sea Doo GTX 300 (that means they are pretty heavy!) PWC's from Wisconsin to Florida twice a year. That said, this last trip to Florida caused me to bend the original straight axle on my trailer. Not fun. I ordered the Timbress Axle -less axles, and after a few hours of work on the trailer, they were installed, square and true. I immediately put the Sea Doos on the trailer to see how the trailer performs with the new axle-less system on it. one word: FANTASTIC!!!! I guarantee if I have to fix this issue again, I will use the exact same product. It is awesome! 736299

Review from a similar Axle-Less in Trailer Leaf Spring Suspension


This suspension system did EXACTLY what I wanted. I replaced the leaf springs, axle/hubs on my small trailer. The new suspension improved the capacity, lowered the bed 4+inches, improved ground clearance and allowed me to rebalance the trailer all WITHOUT having to have any welding done. Everything needs to be measured very exactly and the alignment technique is fairly cumbersome and takes a bit of time. In the end, I have a quiet, steady, strong, low riding trailer.

Review from a similar Axle-Less in Trailer Leaf Spring Suspension


This is my favorite suspension system in all the world! Rides like an absolute dream. Easy to set up and install. Works on any trailer frame size. One thing to know: You don't get the ride height you get with a standard leaf spring suspension. Even with 15-inch wheels, the ride height is pretty low - maybe 10-12 inches of ground clearance to the bottom of the main trailer frame. If you need more ride height, get the lifted version. A few areas of possible improvement? It's difficult to bolt the suspension unit to a crossmember using the middle bolted hole, which uses a tacked-on weld nut. You have zero room for error when drilling the hole through your cross member, and you can't really use the suspension as a template. Hmmm ... also, the hanger plate mounting holes are positioned 1-inch from the bottom of the trailer frame. That makes it very difficult, since I use channel side rails, to use standard 1/2-inch USS or SAE washers on the backside. There isn't room. Just an extra 1/4 of a inch would allow me to use standard washers underneath the nuts on a channel frame. Nitpicking aside, it's amazing. 410020

Excellent, helpful customer service sold me this product, and trust me when I say it's worth the price tag. Pulled the old axle and leaf spring off a 60's era Bantam and swapped out for this with a support bar in between. Bumped up tires to 315/75r16 BFG TA/KO's to match my rig and am amazed at how much better this trailer now pulls. Empty it wad bouncing all over the place with the old axle and leaf spring setup. Now I hardly even know it's there. Was very easy to install, took a couple hours but I am happy with how it turned out. A+++ product and customer service! 172019

They are GREAT! I put them on a small offroad trailer that has followed me all over some really rough roads in remote Oregon, Washington, and Idaho. They have performed flawlessly, helped the trailer tow extremely well, and were the single best upgrade I did to that trailer. Very much looking forward to another summer of exploring! Massive upgrade to the stock axle leaf spring combo, and I have had the opportunity to show it off to alot of fellow overlanders. I cant speak high enough of them. I also purchased a set of airbags for my vehicle which unfortunately have not held up terribly well. I have had to field repair one once already, and neither holds air terribly well. Truth be told they seem very underdesigned for the job they perform. From my super secret high tech pocket internet window.

Review from a similar Axle-Less in Trailer Leaf Spring Suspension


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! 580744

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,

    Combining the Timbren Axle-Less Trailer Suspension System # ASR2000S02 with the Dexter Trailer Idler Hub Assembly # 84655UC1-EZ is a great option for a small trailer and camping. One of the biggest advantages of the Timbren Axle-Less systems is that they increase ground clearance for the trailer since you don't have an axle tube hanging below everything else. If you were only needing the suspension parts for your trailer build then you shouldn't need any other parts to finish your project....

  • Using Timbren Axle-Less Suspension With Electric Disc Brakes
    The Timbren Axle-Less Suspension System has varying weights, as do axles, but in general the Timbren system weighs a bit more than just an axle. You would also be able to use electric disc brakes so long as the system you are using has a mounting flange and spindle, such as the Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - 2,000 lbs # ASR2000S02. This is a system that can work on any trailer with suspension, and you should have no problems using it with your Aluma...

  • Timbren Axleless Suspension System for 265/75R16 Tires.
    The Timbren Axle-Less Trailer Suspension System part # ASR2000S02 states "regular" as opposed to "off road". The off road version part # ASR1THDS02 has more distance between the hub face and the frame of the trailer. These are very popular with the off road camper that have larger 31" x 10.5" or 33" x 12.5" type tires. With your tire size of 265/75R16 that means you have 31.65" x 10.43" tires with that said the Timbren Axle-Less Trailer Suspension System - Spindle w/Brake Flange - Off-Road...

  • Is Distance From Mounting Flange To Front Of Hub Between Idler And Brake Hubs On Axle-Less System
    When using an idler hub or a hub and drum with brakes on the Timbren Axle-Less Trailer Suspension System, part # ASR2000S02, the difference in the distance from the bracket to the front face of the hub as shown in the attached drawing would be the same. The # ASR2000S02is designed for trailers with one or two axles and has a weight capacity of 2,000-lbs. One note: If your trailer does not have a crossmember above the place where you are installing the Timbrens, you may need to reinforce...

  • Available Axle-Less Suspension Systems
    Axle-less systems are not designed for specific types of trailers, but will need to be chosen based on weight capacity and potentially the hubs if you plan on keeping your current ones. For example, Timbren Axle-Less Trailer Suspension System # ASR2000S02 has a 2,000 lb capacity and fits 1- or 2-axle trailers that use regular tires. It works with 3,500 lb hubs # AKHD-545-35-EZ-K. I've added a link to a video review of this system, as well as a link to our page with each of our axle-less...

  • When Fully Compressed Does Timbren Axle Less Kit ASR2000S02 Match Frame Height
    The full deflection range of the spindle on the Timbren Axle Less kit part # ASR2000S02 is 2-5/8 inch. Which also happens to be the same distance from the spindle center to the frame. That means when this is fully compressed it will be the same height as the frame channel. The kit should be used with standard ST rated trailer tires.

  • Can Welded-On Trailer Hub Withstand Sandblasting and Powder Coating
    Your welded-on trailer hubs are likely to be damaged during the process of sandblasting and powder coating which is why you were told to remove the axle. The best option for you, especially since you are converting your trailer to a fish house, is to add new suspension. The easiest and most effective way to do that is to add an axle-less suspension system, such as the Timbren Axle-Less Trailer Suspension System # ASR2000S02. This system is rated for 2,000 lbs and requires new hubs # AKHD-545-35-EZ-K...

  • Self-Adjusting Trailer Brake Assemblies for Timbren Axle-Less Suspension ASR2000S02
    The recommended hub/drum for use with the Timbren Axle-Less Trailer Suspension Kit # ASR2000S02 is either the powder-coat version # AKHD-545-35-EZ-K or the galvanized version # AKHD-545-35-G-EZ-K, both of which are the 10-inch size. You are correct that these hubs require 10-inch brakes and that often a 2K axle uses smaller brakes in the 7 x 1-1/4-inch drum size. With either of these hub/drums you can use our cost-effective etrailer self-adjusting brakes, left-hand # AKEBRK-35L-SA and...

  • How Much Space is Needed Between Fenders and Tires with Timbrem Axle-Less Suspension Installed
    We generally recommend that you have 4 inches between the tops of the tires and the underside of the fender to allow for travel of the suspension. It could require more or less space but it is more likely to require less than more. Four inches is pretty far and the deflection on # ASR2000S02 is 2-5/8 inches so it should be just about perfect depending on the tire size.

  • What Brake System is Recommended to use With Timbren Axle-Less Suspension?
    If you plan on using the Timbren Axle-Less Trailer Suspension System # ASR2000S02, I recommend using electric brakes with your teardrop trailer. To add these, you would first need the hub and drum assembly that is compatible with the Timbren, # AKHD-545-35-EZ-K. For electric brakes, I recommend the Electric Trailer Brake Assembly - Left Hand # AKEBRK-35L-SA and Electric Trailer Brake Assembly - Right Hand # AKEBRK-35R-SA.

  • Best Trailer Axles To Use For A Spring Center To Spring Center Measurement Of 74"
    I do have trailer axles similar to what you are looking for in our Timbren Axle-Less Suspension Systems however, we do not offer torsion axles at this time. In order to recommend a proper replacement axle for your setup, I would need to know the weight capacity of the axle you are seeking. For a Timbren Axle-Less Suspension System, you would use part # ASR2000S02 for 2,000 lb. axles, part # ASR3500S05 for 3,500 lb. axles, or part # ASR5200S01 for 5,200 lb. axles. I have attached...

    Because the trailer doesn't have a traditional size, in order to upgrade to trailer brakes you will need to have a welder install the Brake Mounting Flange for 1-3/4" Round Trailer Axles - 2K # 4-34 which will require the proper jig to ensure placement and alignment. Then you will need to measure your spindles to help get the correct replacement hubs to add the integrated drum.

  • Hubs with 5 on 5 Bolt Pattern that Will Fit a Timbren Axle-Less Suspension System
    There are Timbren axle-less suspension systems that do not come with hubs so that you could add your own such as # AKIHUB-550-35-EZ-K. But the hubs with 5 on 5 bolt patterns that would also fit a Timbren system only accept up to 15 inch wheels. The other issue is that vehicle wheels are not meant to be used on trailers and often have an offset (mounting surface of wheel not in the dead center of the wheel) whereas most trailers take wheels with a zero offset. With that said the hub listed...

    The Timbren Axle-Less Suspension # TSR2000S03 works with 2-3/8" diameter axles, so you'll need to measure the diameter of the axle on your Harbor Freight trailer using a digital caliper like the # PTW80157 to determine if it will work with your existing axle.

The Timbren axle-less suspension systems are simply bolted or welded so you do not have to worry about finding an axle that meets any specific measurements.

A 33" tire like the Goodyear ST255/85R16 part # 724862519 has a section width of 10.04" with a 33" diameter so there will not be enough clearance to use this Timbren system.
