Dragging the frame on steep driveways or rutted backroads is no fun. This Axle-Less suspension raises the deck height with a built-in 4" lift spindle, giving you extra ground clearance to protect plumbing and underbody parts. With the axle beam gone, there’s nothing hanging low, so you can tow confidently over uneven terrain without scraping or bottoming out.
Rattle and bounce make long hauls tiring for both the driver and the trailer. The heavy-duty AEON jounce springs absorb road shock and carry the load, while the rebound springs keep body roll and sway in check. Together they deliver a smooth, stable, and quiet ride—whether the trailer’s empty or fully loaded—so your cargo stays protected and the trip feels steady all the way.
When one wheel hits a bump, the other shouldn’t feel it. Each side of this suspension works independently, meaning road impacts on one side don’t shake the whole trailer. The setup handles tight turns and uneven ground with ease, improving stability and tracking. Built-in camber and toe-in also help reduce tire wear for longer-lasting, even tread.
A rugged trail demands a tough suspension, and this one’s built from heavy-gauge steel with a black powder-coat finish to resist rust and corrosion. The 4-bolt brake flange and 1/2" bolt holes give a solid mount for your braking setup, and the E-Z Lube spindles make bearing maintenance fast and clean. It’s rated for a 2,200-lb capacity and built to take on miles of rough use without flinching.
No need to hunt for a specific axle width—the Axle-Less design bolts directly to any trailer frame. If you don’t have a crossmember, you can add a 2" x 2" steel tube through the built-in holes for reinforcement. The result is a clean install that keeps the frame square while leaving plenty of clearance underneath. It’s a straightforward way to upgrade or build a trailer ready for real-world travel.

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.
