3500HD Axle-Less Suspension with 4″ Drop & Regular Spindle Arms

3500HD Axle-Less Trailer Suspension With 4" Drop

#ASR35HDS03

The 3500HD series Axle-less trailer suspensions are ideal for off-road use. Hangers made from heavy-gage metal support the increased demands of a trailer used on off-road terrain. A softer rubber spring allows for more suspension travel without compromising strength of capacity.

This premium HD Axle-less trailer suspension comes with a 4” drop spindle for use with standard-width tires...for trailers that won’t see much of the trail. Now you can lower the deck of your trailer without the restriction of a thru-axle. 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.”
