Tight driveways, rocky trails, and steep ramps are no match for the 4" lift built into this Axle-Less suspension. With room for tires up to 35" x 12.5" x 20", it gives the trailer the ground clearance it needs for off-pavement use. The design eliminates the thru-axle completely, so you get full clearance from front to back without anything hanging low to snag.
Each wheel works on its own, so bumps on one side don’t send the whole trailer rocking. Built-in camber and toe-in keep things aligned so it tracks straight and wears tires evenly. The AEON springs compress vertically instead of twisting like a torsion axle, which keeps stress down on suspension parts and makes cornering more stable with less roll.
This system is rated for 5,200 lbs and built from heavy-duty steel with a black powder coat finish that resists rust and road wear. The EZ Lube spindles make greasing simple, and if a spindle ever gets damaged, it can be removed and replaced without changing the whole unit. It’s a strong, serviceable setup that’s ready for long miles under load.
No custom axle fabrication needed—each unit bolts or welds directly to the trailer frame. If there’s no crossmember where you’re mounting it, a piece of 2" x 3" steel tubing can tie both sides together using the built-in holes for added strength. Three clear install methods make it easy to reinforce your frame and get everything square so alignment stays right from the start.
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.

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.

They are GREAT! I put them on a small offroad trailer that has followed me all over some really rough roads in remote Oregon, Washington, and Idaho. They have performed flawlessly, helped the trailer tow extremely well, and were the single best upgrade I did to that trailer. Very much looking forward to another summer of exploring! Massive upgrade to the stock axle leaf spring combo, and I have had the opportunity to show it off to alot of fellow overlanders. I cant speak high enough of them. I also purchased a set of airbags for my vehicle which unfortunately have not held up terribly well. I have had to field repair one once already, and neither holds air terribly well. Truth be told they seem very underdesigned for the job they perform. From my super secret high tech pocket internet window.

Ashley, the 4 version doesnt actually give it more travel. Its the same was the standard or the system as far as suspension travel. What the 4 system does it lift the height of the trailer from the ground, depending on what youre doing with the trailer. For an off road trailer I personally would do the 4raise for added ground clearance, just gotta make sure the trailer doesnt get top heavy. The standard system is good for pretty much all uses and the system is for when you need a really low deck height for a lawn mower or go kart for example. I appreciate your review as I am going to be building a small off road campingbug-out trailer to tow behind my lifted FJ cruiser. I havent decided if I am going to go with the standard height or the 4 lift as I am going to be running the same off road tires toyo RT that I have on my FJ on the trailer and I want the trailer to sit around the same height. Did you add brakes to yours? Im planning on either running electric brakes or if available in am going to run surge brakes.

Michael, My trailer was so light even fully loaded that I didnt see the need for brakes and never missed having them.I stand corrected: We did get the 4 lift, but the non-HD instead of the HD because the specs said that it had a bit more travel. and we didnt need the weight capacity. That being said, Im still happy with how this suspension performs. My trailer is on 31s on a stock Cherokee.

Your comments regarding the Axle-Less Suspension are greatly appreciated. To address the issues you have pointed out, we have carefully reviewed our assembly. While we did not come across any major issues, we did however discover a few areas where the quality could be improved, specifically in the areas you brought to our attention. The following improvements have been made to improve the manufacturing process: - Robotic welder gun re-programmed so that it stops from getting too close to the areas adjacent to the mounting holes of the outboard arm and control arm. This will minimize weld spatter. - The distortion of the flat plates is due to the high degree of heat generated during welding. We conducted experiments, changing the sequence of welding operations until we were successful in minimizing the distortion. We apologize if our customer service in addressing your concerns was insufficient at the time of your phone call. Timbren is an ISO 9001:2008 company with an excellent reputation for providing customers with quality products that are well-performing and easy to install.

We just drove 1200 miles mostly at 75mph. The axles work very well in all conditions, trailer ride very smoothly.

Its been a year since Ive installed the new axles on my trailer my comments above still hold true. Im very pleased with the ride quality of the system after a year. The trailer tracks true and has hauled many things other than my motorcycle. Even empty it doesnt hop around like the original stock straight axle did. No regrets on the purchase.
