Rutted roads and steep driveways are easier to handle when the suspension gives you extra height. The Timbren Axle-Less Trailer Suspension uses long spindles with a built-in 4" lift to raise the trailer deck for maximum ground clearance. It eliminates the axle beam completely, so nothing hangs below the frame to drag or catch when you’re off-pavement or loading on uneven ground.
Rattling and bounce wear you out fast. This suspension uses AEON heavy-duty rubber jounce springs to absorb road shock and support the trailer’s load, while rebound springs control body roll and bottoming out. The result is a stable, quiet ride whether you’re hauling gear or running light, and it keeps your cargo from getting tossed around on rough terrain.
With traditional axles, what happens on one side of the trailer affects the other. The Timbren Axle-Less design bolts directly to the frame in two separate units that work independently. Each side moves on its own, so turns feel smoother and the trailer tracks straight even over potholes or washboard surfaces.
Off-road use demands tough parts. Each suspension arm is built from heavy-gauge steel for strength and durability, then finished in a black powder coat that resists rust and corrosion. It’s rated for a 2,200-lb capacity and built to handle the shock of rocky trails and long hauls without bending or flexing.
Keeping your bearings lubed is simple with the E-Z Lube spindles and built-in grease zerks. The system fits any trailer frame width and accepts 2" x 2" steel tubing through integrated holes for crossmember support. It installs with 1/2" Grade 8 bolts torqued to 90–95 ft-lbs and gives you up to 3-3/8" of suspension travel for reliable performance mile after mile.

| 5-5/8" | 8-1/2" | 4-3/4" | 1-3/4" | 3-3/8" | 3-11/16" |
This Axle-Less system requires crossbeam support. If your trailer frame doesn’t have a crossmember in place, you can retrofit it with one, or you can add a support by running a piece of 2" x 2" steel tubing through the square holes cut into these units. You could also add a steel reinforcement bracket to the inside of the trailer frame.

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.

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.
Do you have a question about this Trailer Axle?
