Bumpy roads and uneven ground don’t have to mean a rough ride. This Axle-Less trailer suspension uses AEON heavy-duty rubber jounce and rebound springs that soak up road shock and reduce bounce, rattle, and bottoming out. Each side works independently, so bumps on one wheel don’t throw the whole trailer around. With 1-5/8" of suspension travel and a 2,000-lb weight capacity, it keeps the ride quiet and controlled no matter the load.
Loading gear or equipment is easier when you don’t have to lift as high. The built-in 4" drop spindles lower the deck height for simpler loading and unloading while maintaining strong support for the trailer frame. Even with the drop, the design eliminates the axle beam, giving you more ground clearance underneath. It’s a practical setup that makes towing smoother and more manageable.
This suspension is made with heavy-gauge steel and finished in a black powder coat for long-term rust and corrosion resistance. It’s a solid, durable setup designed to handle tough use and off-pavement travel. The polyurethane bushings never need lubrication, and the E-Z Lube spindles make bearing maintenance simple through built-in grease zerks.
The Axle-Less system bolts directly to the trailer frame and replaces the traditional axle and suspension components. With no through-axle to measure or align, it fits any frame width and simplifies custom builds or retrofits. A 2" x 2" steel crossbeam (not included) can be added through the built-in holes for reinforcement, keeping the frame square while still sitting higher than a standard axle for extra ground clearance.
Uneven tire wear and tracking issues can ruin a long trip. This suspension includes built-in camber and toe-in to keep tires aligned and rolling evenly. The result is better handling, less drag, and longer tire life, so you spend less time on maintenance and more time towing confidently.

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.
