Bumpy roads and uneven ground don’t have to mean a rough ride. This Axle-Less trailer suspension uses AEON heavy-duty rubber jounce and rebound springs that soak up road shock and reduce bounce, rattle, and bottoming out. Each side works independently, so bumps on one wheel don’t throw the whole trailer around. With 1-5/8" of suspension travel and a 2,000-lb weight capacity, it keeps the ride quiet and controlled no matter the load.
Loading gear or equipment is easier when you don’t have to lift as high. The built-in 4" drop spindles lower the deck height for simpler loading and unloading while maintaining strong support for the trailer frame. Even with the drop, the design eliminates the axle beam, giving you more ground clearance underneath. It’s a practical setup that makes towing smoother and more manageable.
This suspension is made with heavy-gauge steel and finished in a black powder coat for long-term rust and corrosion resistance. It’s a solid, durable setup designed to handle tough use and off-pavement travel. The polyurethane bushings never need lubrication, and the E-Z Lube spindles make bearing maintenance simple through built-in grease zerks.
The Axle-Less system bolts directly to the trailer frame and replaces the traditional axle and suspension components. With no through-axle to measure or align, it fits any frame width and simplifies custom builds or retrofits. A 2" x 2" steel crossbeam (not included) can be added through the built-in holes for reinforcement, keeping the frame square while still sitting higher than a standard axle for extra ground clearance.
Uneven tire wear and tracking issues can ruin a long trip. This suspension includes built-in camber and toe-in to keep tires aligned and rolling evenly. The result is better handling, less drag, and longer tire life, so you spend less time on maintenance and more time towing confidently.

I replaced a failing torsion bar suspension and replaced with a timbren suspension it was a straight forward installation.
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!
Hello I just received my order today that I only placed on Wensday. That night at 7:30 pm. I received an email stating your order is ready for shipping! I received my order on Friday WOW FAST FREE SHIPPING. Great product fast shipping. I'm going to start building OVERLAND TRAILERS.
building a ground loading motorcycle trailer the bed drops down flat threw the frame resting on the surface under the trailer allowing the motorcycle to be driven on without ramps or tilting the trailer bed the axle less trailer suspension is the only way to go and it rides better .
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.
I love them ride is great. Quality product and easy installation
Well made quality axle. The box it was shipped in failed. I hope all the parts are there.
Great looking parts, robust design, professional looking welds....Nothing missing...
I contacted Timbren prior to my purchase and received a prompt, helpful reply...
The supplied instructions are complete and straight forward, i'm confident should i have any issues, contacting them will get them resolved...
Love these axles. Will install in a week or 2. Fast shipping
Outstanding product. I installed this set up on a M1102 military trailer. Straight forward install once the original axle is out of the way. The ride is much better and handles the roughest of trails very well. Also, with the more modern hub you have a lot more choice in electric brakes and wheel bolt pattern.
Great product so far after 1 year. Everthing is holding up and i have put it to good use on multiple occasions. The lift kit made my trailer off road capable and performed to my expectations.
I love these. 30k miles and still going. Almost 1k offroad and they're still holding up. Fully loaded my overlanding trailer weighs 2k lbs, empty 1360 lbs. They did settle a little, but I just raised my fenders a little.
In one word: awesome! I used these to replace a wimpy torsion suspension on a small trailer. Torsion is not made for offroad and I also wanted to add some lift to the trailer. This thing improved the ride and handling a lot. Before when the trailer was empty it would actual jump off the ground when I hit a bump or speed hump. Now it actually has travel in the suspension whether loaded or not and the improvement is noticeable right away.
Notes:
1) This is a trailing arm suspension, so in order to stay centered in the existing wheel wells it needed to mount about 8 inches further forward than the existing torsion suspension was. My trailer didn't have frame where I needed it, so I had to do some fabrication to mount the Timbren forward the 8 inches needed.
2) My original suspension the wheel center line was actually above the bottom of the frame rail by a few inches. The Timbren as you can see in the pictures the hub (wheel center line) is 6 or 7 inches below the bottom of the frame rail that it mounts to. So in the end the Timbren with no lift or drop actually lifted my trailer about 9 or 10 inches. This was perfect for my needs because it was WAY too low before and I am using it on really hilly dirt roads and it handles them like a champ!
3) You are most likely going to need a 2 inch square bar tube to connect the two sides for stability. If you are doing the install DIY, I would wait until the Timbren are installed so you can measure exactly how long you need. This stuff is really, really hard to cut so it is nice to be able to tell the metal shop to cut to length when you are buying it. I got mine at a local metal shop.
4) IF you are replacing leaf springs with Timbren, notes 1 and 2 will still apply but you will need to make the measurements to make sure you get the wheels in the same spot under the wheel wells and also measure to see if you need to get the no drop, drop or lift version of the Timbren
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...
Here are some pictures of my Timbren axle installation. I used a 2000#
axle and a 3500# spindle combination. I am running a original 14" tire.
It was a moderately easy installation.
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.
Used this on a camping trailer behind our Jeep. The suspension handled 1000 miles of washboard gravel roads and mild rocky offroading with ease. We don't drive gently and had the trailer airborne at one point. The brackets that we opted to fabricate for them were straightforward and simple to install. I especially like the ground clearance under the trailer that you gain due to the lack of a solid traditional axle. The ride quality overall was excellent, especially given where we took it. In hindsight we should have gotten the 4" travel version as it may have been able to soak up deep ruts at 40mph a bit better. Only mild complaint is that the powdercoating on the leading edges had already begun to flake off when we received the suspension. I hit it with a can of spray paint, but I would have hoped it would be more durable. Overall, I will definitely be purchasing this axle-less suspension again for my next trailer build.
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!
So we had a torsion axle / frame failure and these and a new subframe was our solution! Amazing product upgrade with 12" brakes and 7000lb HD Running 16" BFG ko2 tires ! These are truly bolt on if you don't have frame problems also if your running single axles on the west coast and mountains the 12" brakes are a huge upgrade!!!
Timbrens work great! They make my homebuilt camper tow smooth, straight, and no bounce. Off road they give me better control and don’t make my light camper jump around on the trail. Install was straight forward, instructions were adequate and overall went pretty well. Staff at etrailer helped me pick the right bearings and provided great customer service as usual. I would recommend these to anyone looking to improve their trailers handling and towing characteristics.
Working great
This suspension is fantastic! Until I found Timbren, I was using torsion suspension which were ok but was not meeting my needs. Timbren's axle-less suspension is perfect and my customers are loving their trailers!
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.
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.

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.
