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


  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).

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

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

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

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

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

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

We just drove 1200 miles mostly at 75mph. The axles work very well in all conditions, trailer ride very smoothly.

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

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

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.

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

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

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

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

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,

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

Only been driving around on the axle-less system for about a week now and it has far exceeded expectations. I get better gas mileage, my trailer now sits like it was intended to, my trailer doesn't bounce like it used to, I wouldn't trade this axle system for any other. Just wish I would have known which outboard assembly arm my trailer needed with the axle-less system before I placed my order. Still not a problem though, plan on using the wrong outboard arm to build a different trailer. So far, a great product! 208571

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

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

I think their axle-less design is very clever. The build quality of the suspension part looks good. I have heartburn over the spindle build quality. The spindle is mounted to the suspension and then the trailer wheel mounts on the spindle. The spindles I received are warped from welding. The plate that bolts onto the suspension does not mount flat due to this warping. I called Timbren. The gentleman that helped me was very pleasant. I described the problems and he said he would check his inventory and call me back. He did call me back and said they are all like that. He said get out the grinder and fix what you can and just tighten the bolts super tight, maybe the gap will go away. Really? Wow. The other problems are a LOT of weld spatter where the bolts are supposed to fit and they made a bend in the plate too close to the bolt holes so two bolt heads hit the bend and dont fit flat against the part they are supposed to hold together. Yikes! I am taking the spindles to a machine shop to fix them but I would not have ordered this Timbren stuff had I been warned before hand. So, fair warning. 100490

Your comments regarding the Axle-Less Suspension are greatly appreciated. To address the issues you have pointed out, we have carefully reviewed our assembly. While we did not come across any major issues, we did however discover a few areas where the quality could be improved, specifically in the areas you brought to our attention. The following improvements have been made to improve the manufacturing process: - Robotic welder gun re-programmed so that it stops from getting too close to the areas adjacent to the mounting holes of the outboard arm and control arm. This will minimize weld spatter. - The distortion of the flat plates is due to the high degree of heat generated during welding. We conducted experiments, changing the sequence of welding operations until we were successful in minimizing the distortion. We apologize if our customer service in addressing your concerns was insufficient at the time of your phone call. Timbren is an ISO 9001:2008 company with an excellent reputation for providing customers with quality products that are well-performing and easy to install.

  • Replacement Axle for a 2016 Bigfoot Travel Trailer
    I do have an option for you but we do not currently offer a Dexter straight axle with the spring center and hub face dimensions that you provided. However, we do have the Timbren Axle-Less Trailer Suspension System part # TASR5200S03 which will replace both the axle and leaf springs. This system is actually going to be better than a standard straight axle as it has aeon springs which work to absorb road shock and support the trailer's load better than a standard straight axle. This system...

    In order to use the Timbren Axle-Less Trailer Suspension System part # TASR5200S03 you will just need an idler hub assuming you do in fact not want to use brakes of any kind.

  • Wheel/Tire, Hub and Drum, and Brake Assembly Recommendation for Timbren Axle Less Kit TASR5200S03
    For a brake drum to fit the Timbren kit part # TASR5200S03 that you referenced you would want the part # 8-201-5UC3-EZ.

  • Recommended Timbren Axle-Less Suspension System and Components on Custom Dump Trailer
    The Timbren Axle-Less Trailer Suspension System - 4" Lift Spindle w/ Brake Flange - 5,200 lbs # TASR5200S03 will work well for your dump trailer. Since you are fabricating it, you will get more ground clearance if you put a cross brace directly where you install the assemblies so you don't need to use the 2 inch square bar in the integrated holes that is required when you don't have that cross brace in that location. That will give you just over 2-1/4 inches more ground clearance at your...

  • Recommendation for Timbren Axle-Less Suspension Requiring 2 Inch Lift
    The 5,200 lb Timbren Axle-Less Suspension System does not come with a 2 inch lift option. You can either use the standard # ASR5200S01 or the 4 inch lift # TASR5200S03. If you need a 2 inch lift, then you would need to use # ASR5200S01 and weld a 2 inch plate to your trailer frame where you will be installing the spindles for that required lift. With either option, I recommend the Dexter Trailer Hub and Drum Assembly - 5,200-lb E-Z Lube Axles # 8-201-5UC3-EZ and Electric Trailer...

  • Can Single Axle of Timbren Axle Less Kit # TASR5200S03 be Used on Trailer that Weighs 3,400 lbs
    Yes, a single axle of the Timbren kit part # TASR5200S03 that you referenced would work great on your trailer that is 15 feet long. This is a 5,200 lb axle so your trailer weighing a total of 3,400 lb when loaded wouldn't be a problem at all. There are some benefits to going to a tandem axle trailer as you get a quite a bit more stability in a tire blow out situation but for as lightweight as your trailer would be you'd be totally fine with a single axle Timbren setup.

  • 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...

  • What Type of Wheel and Tire Should be Used on Timbren Axle Less Kits
    We do not have any hubs that will have a bolt pattern of 6 on 135 mm like you mentioned. That said you really shouldn't be using truck wheels on a trailer so with the Timbren Axle Less kit # TASR5200S03 and the recommended hubs # 8-201-5UC3-EZ installed you'd want to use a trailer wheel and tire like the # 724857519A.

  • Recommended Hubs and Drums, Electric Brakes, and Tire/Wheel With Timbren 3,500 lb Axle-Less System
    Replacing existing axles with the Timbren Axle-Less Trailer Suspension System # TASR5200S03 is a great choice since it eliminates a lot of technical information that is needed for traditional axles. As far as wanting to be able to interchange your Jeep Wrangler tires for the ones on your trailer, it is not necessarily recommended. Passenger vehicle tires are made to have a little more give in their sidewall than trailer tires so that they can provide a more comfortable ride. Since the...

  • Tandem Timbren Axle-Less Kit Recommendation for Off-Road Trailer Needing 10k Capacity

  • Should 3,500 lb or 5,200 lb Timbren Axle-Less System be Used for over 3,600 lbs of Loaded Trailer
    Since your axle will ultimately be under the weight of your trailer and it's contents you definitely need to make sure that it is rated for more than what you will be carrying. You need to go with the 5,200 lb weight capacity. For this we have the Straight Spindle # ASR5200S01, 4" Lift Spindle # TASR5200S03, and 4" Drop Spindle # ASR5200S04. This is compatible with the idler hub # 8-213-5UC1-EZ or the hub and drum assembly # 8-201-5UC3-EZ. I recommend going with the hub and drum assembly...

  • Can 3,500 lb Axles be Changed to 5,200 lb Axles and Parts Needed
    The short answer is yes, you can replace your 3,500 lb axle with a 5,200 lb axle. The longer answer is that while you can change to a higher-rated axle, that does not mean your trailer has a higher weight capacity. The reason is, weight ratings are determined by the lowest-rated component, which can be something other than the axle, like the trailer chassis, for example. So you would need to ensure via the trailer manufacturer what the lowest-rated component is. With that said, in order...

  • 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...

  • 5,200 Lb Timbren Axle-Less System With Compatible Hub, Drum and Electric Brakes
    The Warner-style brake assemblies are no longer made and replacement parts are essentially non-existent at this point, so really your best option is going to be replacing your hub and drum as well as brake assemblies. You may also need to weld on a new brake mounting flange, which will be determined by the diameter of your axle. In order to find the correct replacement hubs for your trailer you need to know the weight rating of your axle, and also what bearings your current hub has....
