3500lbs Axle-Less Suspension with 4″ Lift Regular Spindle Arms

3500lbs Axle-Less Trailer Suspension With 4" Lift

#ASR3500S06

The 3500 series Axle-Less trailer suspension is ideal for medium-duty trailers. Our progressive rubber springs and urethane bushings give your trailer a ride that is quiet and smooth. The Axle-Less design allows you to go off road without the usual limitations associated with a thru-axle.

This 3500 lb. Axle-less trailer suspension comes with a regular, straight spindle for use with standard-width tires...for trailers that won’t see much of the trail. For added braking power, a brake flange is included giving you the option to install brakes.

Customer Reviews


"The Timbren system is the answer for rear end sag and soft handling! My 35ft 5th wheel handles much better, and I recommend Timbren without reservation."

- Larry V. - SD

“Timbren's work amazing! Absolutely as good or even better than air bags! Did it myself and only had time to drink 2 beer doing it! Easy install. Thanks for the advice. Simple yet very effective.”
