Rough approaches and uneven terrain are no longer a problem with the built-in 4" lift spindle. The Timbren Axle-Less Trailer Suspension raises deck height for extra ground clearance, giving room for plumbing and frame components when towing over rough roads or steep driveways. Eliminating the thru-axle keeps the underbody clear and improves approach angles so you can pull through dips and ruts without scraping.
Every bump and pothole sends shock through your trailer—unless the suspension fights back. The integrated AEON hollow rubber jounce springs absorb the hit while the rebound springs control body roll and bounce. Together they soak up vibration and keep cargo steady, whether the trailer is empty or fully loaded. The setup delivers stable, quiet travel with 1-3/4" of suspension travel and a total weight capacity of 3,500 lbs.
Instead of a single beam connecting both sides, each side of this suspension works independently. One wheel can move over a bump without affecting the other, keeping the trailer level and tracking true through turns and rough ground. Built-in camber and toe-in help reduce tire wear, and the design fits any trailer frame width so there’s no worry about ordering a specific axle length.
The E-Z Lube spindle makes bearing care quick—just attach a grease gun to the built-in zerk and go. If a spindle ever gets damaged, it can be replaced without changing the whole suspension. Heavy-gauge steel parts with a black powder-coat finish resist rust and corrosion, while the 4-bolt brake flange and 1/2" bolt holes give a solid mounting point for standard hubs and brake components.
Each unit bolts directly to the trailer frame using Grade 8, 1/2" hardware (not included). If the frame lacks a crossmember, a 2" x 2" steel tube can run through the built-in square holes to keep the frame square and strong. The system replaces one complete axle and suspension, giving builders and restorers a clean, straightforward way to upgrade ride quality and ground clearance in a single step.

Hey Alan. I love seeing all your progress pics. However, I think my favorite part is the camper art on the back! Do you have a bucket list location you want to take it to?
Do you have a question about this Trailer Axle?
