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 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 drop spindles built in, you'll get a lower deck height without sacrificing clearance.
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 and a high deck height. This may make it difficult to navigate off-road terrain and to load items into your trailer.
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 drop spindles on this setup will also lower your deck height, making loading and unloading your trailer way easier. 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, there. I'm Michael with etrailer.com. Today we're gonna take a quick look at this Timbren heavy duty axle-less trailer suspension. This suspension system is gonna provide a nice, safe, smooth, and quiet ride for your trailer. You're gonna have these two independent units that will replace your existing axle on your trailer. These do have a weight capacity of one ton or 2,200 pounds.
This will work for your single axle or dual axle trailers that use regular tires. This is not recommended for your triple axle applications. So having the two independent units here can eliminate the need for a through axle. That's going to help increase your ground clearance. Gonna lower your deck height for easier loading and unloading.
It can also help reduce the roll during cornering, and it's gonna fit any trailer width. So it's gonna be very easy to get this fitted onto your trailer. You're not gonna have to worry about finding the exact right length of axle. You can see with our spindles here, we are going to have a four inch drop. So that's going to give us an even lower deck height.
These easy lube spindles here are going to make it very easy for us to grease our bearings. So you can see we've got that built in grease zerk on the outside there. So we can just hook up our grease gun, pump some grease in there. It's gonna come out through a hole on the backside here to fill up that bearing and housing. This does have the option to be removed.
So if the unit is ever damaged, you can just replace the spindle there instead of having to replace everything. This does have the Aeon springs here on the side. You can see those are progressive rate main springs that are going to help absorb your road shock and support your trailer's load as you're going down the road. So it's gonna deliver a nice, smooth, stable ride regardless of your load size. So the more weight you put on your trailer, the more they're going to compress and become stiff. I had to support that weight. If you have a light load or no load at all, they're going to compress very lightly. So it's going to help to reduce the rattling that you sometimes get if your trailer is unloaded. The rebound springs on the backside here are going to act as a return device to minimize that rattle and bottoming out. And that's gonna create the constant pressure on the arm so that the suspension is never completely relaxed. These do have a built-in camber to them, as well as a tow-in that's gonna help keep the trailer to track straight. Reduce the wear on your tires especially as you put it under load. It's gonna make sure that everything is aligned properly. These are super easy to get installed. You can either bolt them on, or weld them to your trailer's frame. They do not include the mounting hardware. You'll have to pick that up on your own. Probably just local hardware store or something like that. One thing to keep in mind, it's possible that these can replace an axle. You won't have to have an axle, but it kinda depends on your trailer. So if you do not have a cross-member above the spot where you want to install this Timbren system, you're probably gonna need to reinforce the frame. You can do that one of three ways. You can retrofit the trailer with a cross member, you can build out the trailer frame, or you can use a standard two inch steel tubing to connect the two Timbren suspension units here. You can see there's a channel on the backside here that you can connect that to. Just your standard two inch steel tubing. You could probably find that in the welding section at a local hardware store, something like that. And so that's only if your trailer does not have the cross member above the spot where you're wanting to install these. So just make sure that your trailer is gonna be nice and supported across there. Those are the three options if you don't already have that support. These are a nice heavy duty steel construction with a black powder coat finish. So it's gonna resist wear and corrosion. It's gonna hold up really well for you. These are gonna do a really good job of helping to absorb that shock. Not gonna need much maintenance at all other than, you know, greasing up, lubricating your bearings there. But the rubber springs aren't gonna require any maintenance. They're gonna hold up really well and do a good job for you. So that's gonna complete our look for today. Again, I'm Michael with etrailer.com. Thanks for watching..
