Dragging plumbing or bumping the frame on steep drives gets old fast. This Timbren Axle-Less Trailer Suspension raises the deck with a built-in 4" lift spindle so the bottom of the frame sits 7-5/16" above the spindle center. That extra space makes it easier to clear ruts, dips, and rough terrain without scraping. The design also eliminates the thru-axle completely, giving the trailer its full ground clearance from rail to rail.
Leaf springs can bounce and rattle when empty or bottom out under load. The AEON heavy-duty rubber jounce springs in this setup absorb road shock and carry the trailer’s weight, while rebound springs keep body roll and sway in check. The suspension travels 2-3/4", cushioning bumps so your cargo rides steady and the trailer tracks straight whether it’s full or empty.
Each side works on its own, so what happens to one wheel doesn’t upset the other. The control arm and trailing arm pivot on strong polyurethane bushings that never need grease. Built-in camber and toe-in keep the tires wearing evenly, and the E-Z Lube spindles make bearing maintenance simple with their built-in grease zerks. It all adds up to a smoother, more predictable tow.
The pair of suspension units bolts directly to the trailer frame and together replace one 5,200-lb axle. Each side includes a 5-bolt brake flange with 5/8" mounting holes and a built-in opening for a 2" x 3" cross-tube if extra support is needed. Heavy steel construction and a black powder-coat finish keep the setup solid and corrosion-resistant for long-term use on single- or tandem-axle trailers.
The spindles accept standard bearings (inner 25580, outer 14125A or 15123) and work with wheel diameters up to 16". Compatible hub and brake setups include 12" hub-and-drum assemblies such as part #8-201-5UC3-EZ with electric or hydraulic brakes. Rated at 5,200 lbs for the pair and backed by a 3-year limited warranty, the Timbren Axle-Less Suspension makes a clean, strong upgrade that replaces leaf springs, shackles, and axle tubes with one smooth-riding system.

1 year later still working great! Very happy with the performance. We have driven at least 20k miles with these springs and have not had a single issue. I also am happy I upgraded weight limits on everything.

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?
