Low-hanging axles often catch on rocks or driveways. This Axle-Less trailer suspension removes that problem altogether by eliminating the axle beam. The standard-height spindles keep the deck height the same, but the open space under the trailer gives you more ground clearance for rough terrain or steep approaches. It fits any trailer frame width, so you don’t have to worry about matching axle dimensions.
Rough pavement and washboard roads can shake cargo loose. The built-in AEON rubber jounce springs take those hits, supporting up to 7,000 lbs while soaking up road shock. Matching rebound springs keep body roll and rattle in check. Together they deliver a stable, quiet ride whether the trailer is loaded or empty, and help prevent bottoming out on dips or uneven ground.
Traditional axles transfer bumps from one wheel to the other, but these two suspension units work independently. When one side hits a rut, the other stays steady, giving better handling in tight turns and over uneven ground. Built-in camber and toe-in geometry also reduce tire wear so your setup stays aligned mile after mile.
Each suspension arm is made from robust, heavy-gauge steel and finished with a black powder coat that resists rust and corrosion. The 5-bolt flange accepts compatible brakes, and the spindles use 5/8" bolt holes for solid attachment. With 2-5/8" of suspension travel and a total weight capacity of 7,000 lbs, it’s a heavy-duty system ready for long-term use.
Greasing bearings is easy thanks to the built-in E-Z Lube spindles. If a spindle ever gets damaged, it can be replaced without swapping the whole suspension. Each unit bolts directly to the trailer frame—just drill 3 mounting holes and add crossbeam support using 2" × 3" steel tubing or a reinforcement bracket. The result is a strong, serviceable suspension that keeps you rolling smoothly.

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.

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.
