Rough roads and bouncing gear can wear down your trailer and your patience. The Timbren Axle-Less Trailer Suspension uses heavy-duty AEON rubber jounce and rebound springs to soak up shock and minimize body roll, rattle, and bottoming out. Each side works independently, so bumps on one side don’t transfer to the other. With 1-5/8" of suspension travel and a 2,000 lb total weight capacity, it keeps your trailer tracking steady and your cargo protected mile after mile.
Traditional axles hang below the frame and cut into your clearance. This Axle-Less system removes the beam altogether, letting you run clear underneath while keeping your deck height the same. The built-in standard-height E-Z Lube spindles and 4-bolt brake flanges make it simple to pair with hubs, wheels, or brakes up to 15" in diameter. It’s a clean, universal-fit setup that bolts straight to your trailer frame and opens up more room for off-pavement travel or steep driveways.
Hauling on rough roads demands more than light brackets and thin tubing. This heavy-duty design uses thick-gauge steel arms and a welded frame plate to stand up to hard use. The black powder-coat finish fights rust and corrosion from water, grime, and road salt. The system replaces one full axle and suspension assembly with two separate, direct-mount units that clamp down tight and stay square with a 2" × 2" cross-tube for support.
Bearing maintenance shouldn’t be a chore. Each built-in E-Z Lube spindle comes predrilled with a grease zerk so you can keep the bearings packed without pulling the hub. The polyurethane bushings in the control arms never need lubrication, cutting down on ongoing maintenance. It’s a straightforward, service-friendly setup that saves time and keeps the suspension ready for the next trip.
Whether you’re building a custom trailer or replacing a worn-out axle, this Axle-Less suspension fits any frame width for single- or tandem-axle layouts. It’s designed for regular tires up to ST205/75R15 and includes a standard 4-bolt brake flange to match industry-standard 10" brake assemblies. With a simple bolt-on install using 1/2" bolts and basic tools, it’s a flexible, durable solution for smooth towing in all kinds of builds.

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?

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.
