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 3" 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 terrain. 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 off-road terrain.
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 want to go off-road. 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 5, 5/8" 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 3" 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.

Hi everyone, Steve here with etrailer.com. Today we're looking together at our Timbren axle-less trailer suspension system. It's a heavy duty with a long spindle, no drop, and your standard five-volt flange for your brakes, and it's rated to 5,200 pounds capacity. Now I wanna start with saying this should only be used for a single or tandem axle trailer, never up past two axles. And it is pretty much used and designed for low pressure off-road tires. Now the spindles, to start off with, can be disassembled separately from the main unit.
So as you see here, this would mount just like that. The spindles have grease zerks on 'em, all the information as far as the bearing sizes, all that kind of stuff, the hubs, the brake assemblies, that's gonna be on the page. If you scroll down into the specs and everything, you can find all that information. Those are gonna be sold separately. We're just looking at the main kit here.
So this is the right hand side, this is the left. This would be one axle. So if you need to do two axles, you need to change your quantity to two in the cart for the whole system here. Now the neat thing about them being separate across this, it's gonna increase ground clearance, so you're not gonna have to need a through axle. You could potentially lower the deck height to make easier load and unloading and those kind of things.
Now these use what's called an Aeon progressive-rate main spring here, that's this big rubber spring. That's gonna absorb road shock. It's gonna support the trailer's load, deliver a smooth, stable ride regardless of the load size. So these are actually gonna compress and become stiffer as your load weight increases, thus boosting your spring strength. The rebound spring acts like a return device.
It's gonna minimize rattle, minimize bottoming out, and they create a constant pressure on the arm itself. So they're going to minimize rattle and bottoming out. But also the suspension's never gonna be completely relaxed. I already talked about the ground clearance and all that. These can fit any trailer width because they're independent of each other. You can install these one of three ways. The first one, in my opinion is the easiest. You get yourself a two by three inch rectangle tubing from your local weld shop, and you slide that through there to that integrated hole. And then you simply need to bolt the suspension to the trailer side of the trailer frame with the bolts that are included. The second option is gonna be to fabricate an inboard extension plate that would sit up here and that attaches to your trailer's frame and then to this, kind of sandwiching in on this part right up here. Now the last way is to install this suspension hanger here to the trailer's frame and an existing crossmember in the area where you want to install the suspension. So a couple options that you have out there. Just check your personal needs, wants, desires, what you're doing, and make sure you get the best possible choice to fit your needs. Now again, these are rated at 5,200 pounds capacity total when used in conjunction with each other, meaning I've got both of 'em installed correctly. Now these are gonna be easy to install, easy to align. You simply bolt or weld 'em into your trailer's frame. And again, hubs, bearings, brakes, that's all sold separately. As you can see, they're heavy duty steel. They've been black powder coated to give you that nice corrosion-resistant finish. Now these also have built-in camber and toe-in and that's gonna help the trailer to track straight, thus reducing wear and tear on your tires, your brakes, and your overall load. Now again, these are designed for over-landing or off-road adventures, so keep that in mind when you're purchasing this. That's what they're designed for. That's why they have the suspension and everything. So make sure you're getting the right part for your specific needs. As always, we would love to see feedback on the websites and reviews, maybe some photos before and after. How are you using these What are you using them for What could the manufacturer improve on to make it better What kind of things are great that you love about it That's gonna wrap it up. I'm Steven, thanks for watching.
