Rutting or steep driveways won’t slow you down. This setup builds in a 2" lift that raises the trailer deck height for extra clearance. With the axle beam gone, nothing hangs low to snag or drag when you leave pavement. The long spindle design fits wide, off-road tires so you can roll over rough ground without worrying about bottoming out or clipping plumbing.
Bumpy roads don’t have to mean bouncing cargo. The jounce and rebound springs work together to absorb road shock, cut down frame vibration, and keep things steady whether the trailer’s loaded or empty. The AEON heavy-duty hollow rubber design soaks up hits and keeps suspension movement under control so the trailer tracks straight and quiet mile after mile.
Instead of a solid axle tying both wheels together, each suspension unit operates independently. That means when one wheel hits a pothole, the other side stays stable. You get better control on uneven terrain and less sway in corners. Built-in camber and toe-in keep tire wear even so you don’t have to fight cupped tread or alignment issues later.
This heavy-duty system handles up to 3,500 lbs without flinching. The robust steel construction is made to take abuse from off-road use and heavy gear. Black powder coating protects against rust and corrosion, so it stays solid through mud, rain, and salt. It’s made for single or tandem-axle setups, with 2-5/8" of suspension travel for consistent support under load.
Keeping bearings greased is straightforward thanks to the built-in E-Z Lube spindle. Just attach your grease gun to the zerk fitting—no disassembly needed. And if a spindle ever gets damaged, it’s replaceable without changing the whole suspension. That saves both time and money while keeping your trailer rolling smooth for years.

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.

Can't wait to hear how the install goes, Christopher! What kind of trailer are you going to install them on?

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.

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.
