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.


Timbren Axle-Less Suspension vs. Other Suspension Systems

There are many suspension options for your trailer or camper. So, what makes Timbren Axle-Less different?


Leaf Spring Example

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.


Torsion Axle Example

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.


Timbren Silent Ride Example

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.


Timbren Axle-Less Suspension Parts

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.


Timbren Axle-Less Suspension Parts Diagram

  1. The jounce spring supports the weight of your trailer and cargo. It easily absorbs road shock and is constructed of AEON heavy-duty, hollow rubber.
  2. The rebound spring delivers a smooth, stable ride - regardless of how much cargo is on the trailer. It controls the movement of the jounce spring to minimize trailer body roll, bounce, rattle, and bottoming out.
  3. The trailing arm with integrated hanger attaches 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 polyurethane bushings that never require lubrication.
  5. The E-Z Lube spindle is simple to grease. If damaged, it can be removed and replaced, saving you both time and money compared to a traditional axle.
  6. The built-in hole accepts 2" x 2" steel tubing (not included) to add support to your trailer's frame. The tubing sits higher than a trailer axle, providing additional ground clearance.

Installing the Timbren Axle-Less Suspension

Measuring Diagram

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 5, 1/2" bolts (not included).


Keep Your Trailer Frame Square

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.


Crossmember Installation

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.


Steel Tubing Installation

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.


Reinforcement Bracket Installation

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.

I used these parts to build a motorcycle trailer. (See attached pictures) It pulls and handles like a dream. The Atwood coupler and the Timbren axle-less suspension are both very well designed and of high quality manufacture. I would recommend these parts to anyone.

I love this suspension. Even empty, the trailer huggs the road and doesnt bounce around. Its smooth as silk when loaded.

The parts and prices are great but really for me was Kate Answering my questions and following up later to make sure everything was fine. Hands down best customer service experience I have ever had I don’t see taking my business anywhere else.

This was the best upgrade I’ve made to just about anything really, any trailers I buy in the future will get the timbren suspension.



by:

excellent product, works so well. needed to lower the motorcycle trailer, and a standard axle was going to place the height of the trailer bed too high. the ride is awesome and the install was simple.

i ordered on a tuesday night and had thursday afternoon. great service

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.

by:

I used these axles in a different way than most would. I needed a trailer that was small, could handle tight switch-backs, carry 600 lbs and be light. I had this idea and as a retired design engineer I saw a great possibility in this axle. I have made four of these trailers now, one as a camp trailer, 2 for trail work for State Parks and one as a utility trailer.



by:

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



by:

I rebuilt a 4 x 8 trailer using the Timbren Axle-Less Trailer Leaf Spring Suspension and it works great. I would recommend it to others.



by:

They have more pros than cons, but the second set I bought broke the flat plate that holds the spindle at about 8 months. The steel quality seemed less than I would expect since it basically peeled it back like a pop can as you can see in the pictures. Otherwise I like the clearance and ride. They last 2-3 years where the torsion axles I replaced would wear out in 4 months after driving down rough gravel roads. There is a grade zerk on the underside which I didn't realize until I bought the second set. That would have helped the first set last longer had I known about it.



by:

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.



by:

I put these on an off-road trailer build. They have been fantastic! I've done many miles and they held up great. Highly recommend.

Part numbers from the originals are the preferred way to find replacement parts but the other option is to measure your spindles at the various points where the seal and bearings ride. The linked diagram shows you these points on the spindle that you can measure with your digital caliper. This is more reliable than measuring the old parts...

  • How to Choose the Correct Timbren Axle-Less System

  • What Wall Thickness Should Be Used For Square Tubing To Add Support For Timbren Axle-Less System

The arrow on the photo is pointing to the 2 inch x 2 inch hole that is designed to be used to add additional support if needed. They told me that you should use 1/4 inch thick walls for the 2 x 2 channel.

  • Is the Timbren Axle-Less Trailer Suspension System a Good Choice for a Motorcycle Trailer
    The Timbren suspension system, like # A20RS440, is designed to be toe-in when there is no load on it. So when the load is placed on it it will push the tire out so that it is riding straight on the ground. Provided the trailer is not overloaded and the tires are trailer tires and inflated to the maximum psi as indicated on the tire, then you should not see excessive wear and get more than just a few thousand miles out of a set. A regular axle has a bow in it. That bow should be pointed...

  • Amount of Spring Deflection of Timbren Alxe-Less Suspension # A20RS440
    You are correct, the Aeon spring does indeed function as a dampener, and should not need additional dampening. Each unit is rated at a 1000 lb capacity, so two sets or four units would provide a 4000 lb capacity. The 2-5/8 inch dimension shown is the static position, but this exact dimension will depend on the construction of your trailer and how heavy it is. The engineering folks at Timbren tell me that the springs are capable of 2-1/2 inches of travel or deflection.

  • Timbren Axle-Less Trailer Suspension System Recommendation for a 1977 13 ft Scamp Trailer
    Converting a torsion axle trailer to a trailer with a Timbren Axle-Less Trailer Suspension System has been done before and most people who have done this really prefer the smoother ride and increased ground clearance. Timbren 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...
