When bumps and washboard roads make towing rough, this suspension keeps things steady. The built-in AEON jounce springs absorb road shock and support up to 2,200 lbs, while rebound springs control body roll and minimize rattle or bottoming out. Each side works independently, so uneven ground won’t throw your whole trailer off balance. The result is a smooth, quiet ride that protects your gear no matter the load.
Traditional axles hang below the frame and steal ground clearance. This axle-less system eliminates that beam entirely, giving you more space under the trailer to clear rocks, ruts, or steep driveways. The standard-height long spindles keep deck height the same for easy loading while still letting you run wide off-road tires up to 33" tall with 15" or larger wheels. Built-in camber and toe-in keep tire wear even as you put on the miles.
Hauling on rough roads calls for hardware that can take abuse. These heavy-gauge steel suspension units bolt directly to the frame and carry a full 2,200-lb rating. The E-Z Lube spindles make bearing maintenance simple—just pump fresh grease through the zerks without tearing everything apart. If a spindle ever gets damaged, it can be replaced without changing the entire system, saving time and cost over fixed-axle setups.
Because there’s no axle beam setting a fixed width, this setup fits any trailer frame spacing. Each unit bolts on with 1/2" hardware (not included) and can be welded if preferred. A 2" x 2" steel tube can slide through built-in square holes to act as a crossmember for added strength while still sitting higher than a standard axle. Whether you’re fabricating from scratch or rebuilding an older trailer, it’s easy to line up, bolt on, and get rolling.
From highway stretches to backcountry tracks, the Timbren Axle-Less Trailer Suspension keeps towing predictable and stable. Its independent action smooths out sharp turns and uneven trails, while the black powder coat resists rust and corrosion for long life in any weather. Wherever you travel, this setup delivers solid control and real-world durability every time you hitch up.

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.

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.
