Rough pavement doesn’t have to rattle your cargo or your nerves. This Timbren Axle-Less Trailer Suspension uses AEON rubber jounce and rebound springs to take the hit from bumps and potholes. The setup absorbs road shock, minimizes bounce, and keeps the trailer stable whether it’s loaded or empty. With 2-7/16" of suspension travel and 1-3/4" of deflection under load, it rides smooth and quiet mile after mile.
Dragging a low axle over ruts or driveways gets old fast. This system eliminates the thru-axle completely, boosting ground clearance while keeping the same deck height. Each of the two independent suspension units bolts directly to the trailer frame, so what happens on one side doesn’t affect the other. You get a stable, balanced ride and the extra room underneath to clear rough terrain or protect plumbing and wiring.
Finding the right axle width can be a guessing game—but not with this one. The Timbren Axle-Less design fits any trailer frame width and can be bolted or welded in place. The strong steel housing takes hard use, and the black powder coat fights rust and corrosion. If your frame doesn’t have a crossmember where the units mount, the built-in square holes accept a 2" x 2" steel tube for added support and frame stiffness.
Regular grease service keeps any trailer rolling smooth. This system includes standard-height E-Z Lube spindles and idler hubs pre-fit with inner and outer bearings (L44649), races (L44610), and seals (10-9). Grease zerks on the spindles make bearing maintenance simple, so you spend less time under the trailer and more time towing with confidence.

Hands down better than axles. Much smoother ride and quieter. Ive had no worries or trouble with axle-less suspension for 1 year now. Thanks again Timbren

This suspension is rated for 2000 lbs, and my trailer weighs in at 1600 lbs. After about 30,000 miles though, elastic bumpers where basically flattened out. Good news is that these are super easy to replace, but bad news is that Ill be replacing the whole system with the 3600 lb system. Im guess that the bouncing on the suspension, even with a trailer that was under spec, exceeds the 2000 lb rating. So, the short story - these systems arent rated to the weight of your trailer, but the force of your trailers bouncing. Extra bad news - each of the Timbren systems are different sizes. The arm in this new one is longer, the distance of the hub from the suspension arm is greater, even the holes for mounting it are different spaces. So, it aint like you can just bolt on a different Timbren. Since the fenders on my camper are fixed, Ill be welding a plate over the existing drill holes and drilling new ones. I wish I had known before I purchased the first suspension system that the rating isnt about trailer weight. Still, the folks at etrailer have been super nice through the whole process.
