Get more clearance and a smoother ride when towing with Axle-Less trailer suspension. Built-in shock absorption limits rattle and bottoming out. E-Z Lube, standard-height spindle keeps your deck height the same. Fits any trailer frame width.
Features:
Specs:
Note: This Axle-Less system requires crossbeam support. If your trailer frame doesn't have a crossmember in place, you can retrofit it with one, or you can add a support by running a piece of 2" x 2" steel tubing through the square holes cut into these units. You could also add a steel reinforcement bracket to the inside of the trailer frame.
Get more ground clearance and a more comfortable ride when you're towing with Timbren's Axle-Less trailer suspension. This suspension system provides great shock absorption to comfortably get you where you need to go and to protect your precious cargo as you travel - even on rough pavement. With 2 independently operating units, you'll get better handling when making tight turns. And because this system eliminates your axle and has standard-height spindles built in, you'll get more clearance without having to raise your deck height.
There are many suspension options for your trailer or camper. So, what makes Timbren Axle-Less different?
Axle-Less systems are a definitive upgrade over traditional leaf springs, in part because they allow you to do away with your thru-axle, allowing for maximum clearance. As you've probably noticed, having a leaf spring suspension means that your axle will always hang at least a few inches below your trailer's frame, resulting in limited ground clearance. This may make it difficult to navigate rough roads.
In addition, while leaf springs do a great job of supporting an even load, they may cause your trailer to bounce and rattle when it's empty or to bottom out with a heavy load. And they don't offer any type of shock absorption for a smooth ride - unless you have upgrades built in. With Timbren's Axle-Less system, gone are the days of dealing with these annoyances - this suspension is designed for a quiet, balanced ride, whether your trailer's fully loaded or empty.
A torsion axle is a step up in terms of shock absorption, and it provides more clearance than a traditional, leaf spring suspension, but that crossbeam will still hang down some. And if your torsion axle gets damaged in any way, it can't be repaired - you'll have to replace the entire thing with a setup that matches your exact trailer frame width.
With the Axle-Less system from Timbren, you won't have a low-hanging axle beam to get in the way when you're driving on rough roads. The standard-height spindles on this setup will keep your deck height the same, so you'll get that extra clearance and still be able to easily load and unload your trailer. And the rubber springs and independent operation both combine to absorb shock and deliver a smooth, easy ride. In addition, the Axle-Less system can be easily maintained over time, and it will fit any trailer frame width, so you don't have to worry about potentially ordering the wrong size like you might with other systems.
Another suspension upgrade on the market is Timbren's Silent Ride. This setup is a great option to reduce bounce and rattle because it has the same AEON rubber springs as the Axle-Less system. But the Silent Ride still requires an axle, so you won't get the same ground clearance or low deck height as you will with the Axle-Less suspension.
The Timbren Axle-Less suspension is designed with you in mind. All of the parts work together so you can tow your trailer comfortably - regardless of load size.
The first step in installing the Timbren Axle-Less suspension is to make sure that the mounting points for each unit are directly across from each other. The easiest way to measure this is to mark the desired mounting points on your trailer's frame. Then measure the distance between these points and the center of your trailer coupler. These measurements (A and B) need to be within 1/8" to keep your trailer frame square.
Once you have your mounting points lined up, you'll be ready to install the system. Drill 3 holes into your trailer frame at the desired mounting points. Then bolt each unit to the frame with Grade 8, 1/2" bolts (not included).
Because Timbren's Axle-Less system eliminates your trailer's thru-axle, you'll have to find another way to get the crossbeam support that keeps your trailer frame square. You have a few different options to do this depending on your application and how much fabricating you're comfortable doing.
If you're building a trailer, the best option is to begin building with the Timbren Axle-Less in mind and include a crossmember where you want to install the units on your frame. You can also retrofit an existing trailer with a crossmember.
If you don't have a crossmember where you want to install the Axle-Less system (and you don't want to add one), pick up a section of 2" x 2" steel tubing from a nearby weld shop. This tubing will serve as a support to keep your trailer square. It will hang only about an inch down from your trailer frame, providing more clearance than a thru-axle.
After you've mounted both of the units to your frame, you'll need to drill 3 holes into the steel tubing and into the built-in, square holes. Then, insert the tubing through the holes and secure it with 3 bolts (not included) on each side.
The last option is to fabricate a reinforcement bracket that can be attached to the inside of your trailer frame and to the Axle-Less suspension. It may be a little harder to fabricate a compatible bracket than to mount steel tubing, but you may get additional clearance with this method.

Trailer suspension and disk brake performance is outstanding big big difference over leaf spring and electric drum brakes.
Installation required modifications to the frame to monut the timbren suspension
Timbren saved our RV road trip! The leafs on the axle on our 2018 Jayco TT came apart while driving in Maryland. We tried going to the manufacturer, but they were useless. Going to a RV mechanic meant being grounded for at least 2 months. Then we found Timbren. With the help of Timbren's excellent staff we purchased axle-less system through etrailer, who made sure we got as quick as possible. It came ahead of schedule, my husband installed the Timbren system and we were back on the road! The axle-less system is better than the original manufacturers. If you plan on taking your RV or TT farther than 100 miles GET THIS INSTALLED and get it through etrailer.
Easy to install. Tow like a dream!

Ready to buy another set, and make another trailer.
Great product.. My company manufactures trailers with our own axle-less suspension, however we have abandoned our own design in favor of the Timbren system. It is far superior and more cost effective to use the Timbren. Also, the Timbren can be adjusted for camber, a nice feature on a trailer. Just be sure to order the correct spindle for your application. Exchanging the spindles with etrailer became a nightmare. I eventually kept the original spindles and bought new ones from Timbren directly.
I use these axles on off road trailer built to tackle the toughest 4x4 trails and the have held up to all the beating our customers can dish out
We don't use our trailer often but when we do, it performs flawlessly. We are so grateful for the function axles. It gives us the desired cushioned ride
Easy to install. Big difference in trailer's suspension and handling. Highly recommended.
Again nice addition to my trailer
Product was great easy to install, haven’t towed with it yet as I’m sill working on the repairs!
Thank u for your business!
The axle-less suspension worked very well for my boat trailer. The suspension was easy to attach to the trailer frame and provided a lower profile than the traditional leaf spring and axle system.
The service from etrailer has been great! They have been very helpful through the entire purchasing process. My one star is due to the quality of the product. First, for something as heavy duty as these are, you’d expect better packaging. On arrival, one of the spindles was sticking out of the box and the hand holds were torn on one of the other boxes. I was a little worried what I might find in the damaged box but everything seems to be intact. The disappointing part is the quality of the welds. For the price you are spending on these, I would expect a higher quality of fabrication. There is undercut in the welds that hold the three support plates together and big ol sloppy welds every where else. Unsure of what to do as my trailer has been designed around this suspension system.
I purchased the 3500 lb. set w/4" drop. Wish they made a 2" drop. Install was fairly easy, but most of your time will be consumed with alignment measurements, acquiring shims, and making adjustments. I was lucky to have a very square trailer frame. However, the "slop" in the all of the mounting bolts (especially, the spindle mounts) is more than the 1/8" window they specify. You will want to preload all bolts before tightening, and then measure for alignment/toe-in. The units are supposed to have camber built-in, but it's not near enough (more shims). Also, this suspension has more travel then the documents indicated. I had to re-mount my fenders 1" higher to keep the tires front hitting. When fully loaded, you might have 1" of travel left. All that being said, the ride is better than I anticipated. It's less bouncy than a torsion axle, and very quiet. If I was building a trailer from scratch, I would use this system, again.
It is important to know that your wheels are going to sit very tight to the trailer frame. I needed to add an extension to the hub for it to clear the sides of the camper I built.
We made an amazing creation out of those two axle-less axles.
We made a large fuel cell that is used for offroad use and it has worked excellent this entire time.
They are really great products and we would love to work with them again.
Actually, we do a ton of social media stuff and youtube and if you ever have interest in sending us products to build content around, I would love to have the opportunity!
Thanks,

Very smooth pull. I'm very impressed on how the trailer pulls. My traditional axle trailer seemed to bounce a lot on the highway which made a lot of noise, but with the Timbren Axle-less that I installed on a new trailer, the trailer is so smooth and way less noise.
Great product.
The trailer rides great down the road and no more worries about saltwater and rusty leaf springs. Not a cheap option but I’m very happy with the setup. When installing, just be sure to measure accurately and have sharp drill bits. A drill press type of guide also helps ensure correct drilling angles. The first picture is of a mounting gusset a local welding shop made. One is needed for each side and necessary to provide needed mounting strength-at least on my trailer frame. Pics 2 and 3 show the mounted suspension on one side of the trailer. Pic 4 shows the suspension on one side of the trailer with the axle attached and a separately purchased disc brake assembly mounted on it. Finally, pic 5 shows a 2” box channel between both suspension assemblies. Independent suspensions would have been nice, but I wanted to ensure trailer rigidity was maintained. So, after one year, so far, so good. It’s all smooth sailing down the highway.
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!
Installed the Timbren Axle-less suspension a little over a year ago and approximately 5000 miles ago. I have been extremely satisfied with the installation and performance thus far and have had no issues. I also chose to install an optional crossmember for more strength using a 1/4" thick piece of 2x3 steel. I had to increase the weight capacity of my campers suspension due to renovating the interior completely and adding more weight. I also strengthened the frame to accommodate the extra weight. In addition to installing the Timbren 5200LB system I installed new 12" electric brakes and upgraded to 225/75R15 tires with E load range rating.
