Rutted roads and deep dips can hang up a trailer with a low beam axle. This Timbren Axle-Less suspension clears that problem by eliminating the axle beam entirely. Each of the two independent 7,000-lb-rated units bolts directly to the trailer frame, giving wide off-road tires (35 x 12.5 x 20 or smaller) room to move without raising deck height. The long, standard-height spindles keep the stance level while adding the clearance you need for off-pavement travel.
Rough terrain can beat up gear and make towing a chore. Timbren’s built-in jounce springs absorb road shock and support the load, while rebound springs control body roll and bounce. With 2-5/8" of suspension travel, this setup keeps the trailer steady and quiet no matter how full or empty it is. Each side works independently, so bumps on one wheel don’t shake the whole frame.
Hauling heavy gear calls for serious hardware. These heavy-gauge steel suspension arms and control mounts are built for abuse and protected by a black powder coat to resist rust and corrosion. The 5-bolt brake flange accepts 12" brakes, giving solid stopping power that matches the 7,000-lb weight rating. E-Z Lube spindles make bearing maintenance simple with built-in grease zerks.
Custom builds and repairs get easier when you don’t have to hunt for a specific axle length. The Axle-Less design fits any trailer frame width, and mounting is straightforward—each unit bolts on with Grade 5, 5/8" hardware (not included). If you don’t already have a crossmember, you can add one or run 2" x 3" steel tubing through the built-in holes to keep the frame square while still keeping everything tucked high for maximum clearance.
Old leaf springs can creak, rattle, and wear unevenly. This suspension replaces all that with a simple, solid layout—polyurethane pivot bushings that never need grease, replaceable spindles, and corrosion-resistant finishes. The result is a quieter, smoother ride that holds up through long miles, heavy loads, and off-road abuse without sacrificing comfort or control.

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.
