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 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 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.

Hello neighbor Steven here with etrailer.com. Today we're looking at the Timbren axle lift trailer suspension with the heavy duty long spindle and a four inch lift. Now folks, this is what they consider a five volt spindle and it's rated at 7,000 pounds capacity. Now folks, I'm kinda limited on space today, so I wanted to kind of throw everything up here the best I could and give you an idea of what you're gonna give. But I wanna start off, I show you an image so you will get all the hardware and everything you see in the picture. I don't have the hardware laid out today due to space.
So again, you're left and right hand side, two spindle assemblies and all the hardware spacers, castle nuts, Kotter pins, everything you see there. Now getting into it folks, this will help deliver a nice smooth, stable, quiet ride regardless of the load size up to 7,000 pounds. This internal jounce here is gonna absorb the road shock and also support your trailer's load. The spring does rebound, which is gonna reduce body roll rattle, bottoming out, those kind of things. And it has a built-in Camber and tow in to help reduce the wear and tear on those trailer tires.
The units do work independently, one from each side, so what affects one side will not affect the other side. So that's a nice upgrade and feature of these as well. Now again, I don't have the hardware laid out here, but roughly to show you what this guy looks like installed pretty much something like this and you'd have it all bolted together obviously and everything. It does have a nice black powder coat finish. It's gonna resist rust and corrosion.
It is super, super thick, very robust, heavy gauge steel construction. It's gonna handle all the road abuse that you can send its way. Now the long spindle here accepts wide Off-Road Trailer Tire, so that's a nice feature and it is two separate units so you can bolt directly to your trailer frame and it is designed for like over-landing, off-road, that kind of stuff. Now the nice thing with a drop spindle is that it'll keep your trailer deck height the same but increase the ground clearance. Now everything here has built-in greaser, so you can see on the tip of the spindle there to make maintenance and that kind of stuff, minimal and easier to get to.
So it's compatible with the tire size of 235 85 16 or larger, and a wheel diameter of 16 inches or larger, the bearings and everything is sold separately. That's part number 25580 on the inner bearing. And the outer bearing is a 14125A. And then those matching races are sold separately. The grease seal would be a 10-36 also sold separately. Now folks, this is designed for a single tandem use trailers. Do not use it for three axles, it's all rated for two axles, most. Now if you want to do two axles, you would need two sets of this kit. Now keep in mind your hub drums, all that stuff is sold separately, 7,000 pound capacity. And one other thing to note that you can kind of see the square that goes all the way through. Let me zoom in here. So this square goes all the way through. That's for installing a cross beam support. So this axle system still requires a cross beam support. If your trailer frame doesn't already have one in place, you can retrofit it by simply getting a two by two inch steel tubing and run it through those and cut it to length as needed. Or you could also simply add a steel reinforcement bracket on the inside of the trailer frame. Well, I think it's gonna wrap it up for our look at this Timbren axle list trailer suspension. Again, you're getting the whole kit, all the hardware and everything included as you see in the photo there. Folks, thank you so much for your time. I'm Steven, thanks for watching and have a great day.
