Bumpy trails and washboard roads make trailers shake and rattle, but this heavy-duty Axle-Less suspension smooths it out. The AEON rubber jounce springs absorb hard hits and road shock while the rebound springs control the motion to limit bounce, sway, and body roll. The setup gives a stable, quiet ride whether the trailer is empty or loaded, keeping everything inside from getting tossed around.
Traditional axles hang low and limit clearance. This Axle-Less system removes the beam completely, so nothing drags or snags underneath. The 4" drop spindle lowers the deck height for easier loading while still giving the ground clearance needed for off-road travel. It fits any trailer frame width and eliminates the need to hunt for a specific axle size, making it a flexible choice for custom or rebuilt trailers.
Hauling gear off pavement or down gravel roads demands tough hardware. These suspension units are made from robust, heavy-gauge steel built to handle abuse. Each side bolts directly to the trailer frame with 1/2" hardware and supports up to 2,000 lbs. The black powder-coat finish resists rust and corrosion so the parts stay strong through years of use.
Maintenance stays easy thanks to the long E-Z Lube spindles. Built-in grease zerks let you service bearings without disassembly, and if a spindle gets damaged, it can be replaced on its own. Each side of the suspension works independently, so one wheel taking a hit doesn’t upset the other. That means better control, less tire wear, and a safer, more predictable pull on uneven ground.
This setup is designed for wide, off-road tires up to 33" tall and wheels 15" or smaller. The 4-bolt brake flange makes it simple to add compatible brakes when needed. With built-in camber and toe-in for proper alignment, it keeps tires tracking straight and wearing evenly—no matter how far the road takes you.

I mounted these axels on my off road trailer, this trailer has 37" tires (same as my jeep) tracks perfectly on the road at 60 - 70 mph, Last summer I pulled this trailer on the Rubicon trail were while on the rocks the lean angle was so extream my trailer turned over on its side, when I winched my trailer back on its wheels all the weight of the trailer was on one axel. Timbren Axle-Less trailer axels are so well built and strong nothing bent, everything stayed intact. There is no sag in these axels as well. I could not be more pleased with the Timbren axels.
Very pleased with the design and heavy duty construction of these axles. Used them to build an off-road trailer and they performed flawlessly throughout many challenging trails and off road situations. My only complaint is that the ez-lube hub design does not take grease very easily. I've had to disassemble the hubs to properly grease both bearings due to the inadequate amount of grease flowing into the bearings.
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.
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!
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.
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.
Atrocious packaging! Timbren should be ashamed of how they're sending this stuff out - packaged with flimsy paper and nothing else. Not surprisingly, the spindles arrived damaged to the point where replacements are being sent, and the main arms have big sections of powder coating missing from where the rattled around in the box.
On the flip side - Etrailer has been awesome to work with and will be sending out replacement parts. I'll update this post after the parts arrive
Just receiving my parts, to start with box's got beat up (have no suggestion), Packed very well good tape (use more around center will add strength), the lay out will begin in a week or so, thank you, p.s. shipping time was Awesome
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 .
Do you have a question about this Trailer Axle?
