When you’re tired of dragging an axle tube over rocks or ruts, this axle-less suspension solves it cleanly. The Timbren Heavy-Duty Axle-Less Trailer Suspension - Long Spindle w/ No Drop - 2,000 lbs eliminates the thru-axle completely, giving you full ground clearance while keeping your trailer deck height the same. The long, standard-height spindle is built for wide off-road tires and fits any trailer frame width. The 4-bolt brake flange and 1/2" bolt holes make mounting straightforward, and the built-in E-Z Lube spindles make it simple to grease bearings whenever needed.
Rough terrain doesn’t have to mean a rough ride. This system’s jounce and rebound springs absorb road shock, control bounce, and keep the trailer stable whether it’s packed full or running light. The AEON rubber springs handle the load and smooth out the bumps, while the rebound spring keeps the trailer from rolling or bottoming out. Each side works independently, so what one wheel hits doesn’t transfer across the trailer.
Built to take abuse, the heavy-gauge steel construction handles off-road use and long miles without flexing or warping. The black powder coat finish resists rust and corrosion from road spray, salt, and grime. Everything about the design—from the welded trailing arms to the sealed bushings—is aimed at durability and long-term reliability.
Keeping things serviced is easy with the built-in grease zerks on each spindle. Bearings can be cleaned, inspected, and greased without removing the hub. If a spindle ever gets damaged, it can be replaced without having to change the entire suspension. Compatible bearings include inner L68149 and outer L44649, with races L68111 and L44610.
Whether you’re starting from scratch or upgrading an existing setup, this suspension gives you flexibility. The two independent units bolt directly to the side of the frame, and a 2" x 2" steel tube can be used through the built-in square holes for crossmember support if needed. With 1-5/8" of suspension travel and a 2,000-lb capacity, it’s a solid foundation for a smooth, quiet ride and the clearance you need for off-road adventures.

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.
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.
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.
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
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.
Great delivery time
After much over analysis and contemplation, They were easy to bolt up and install.
I just received everything
Boy, this is heavy duty!
I’m very impressed.
Product exactly what I need. People at etrailer where beyond extremely helpful! Great to deal with!
Great product. Well made! Can’t wait to get it on a trailer. Includes grease fittings too!
Great suspension system. I used these for a severe duty off-road trailer and I am truly amazed at how well the trailer handles extremely rough terrain.
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...
