Timbren 3500 lb HD Trailer Suspension w/ Long Spindles

Sale price$1,495.71

The 3500 lb HD Axle-Less trailer suspension is designed specifically for off-road use. Components made from heavy-gauge steel support the increased demands of a trailer used on off-road terrain. A softer rubber spring allows for more suspension travel without compromising strength or capacity, providing you with the best ride quality to protect your cargo on and off the trail.

This premium HD Axle-less trailer suspension – designed for off-road use – comes with heavy duty outboard arms, a 4” lift and long spindles for use with wide off-road tires larger than 235/85R16. A brake flange is included if you plan on using brakes with your trailer suspension.

Due to higher than anticipated volumes we're currently experiencing a 2 to 3 week lead time.

The genius of the Axle-Less trailer suspension has more to do with what’s not there than what is:

  • Less hassle! You don’t have to worry about ordering the correct axle size.
  • Less time! You can retrofit any medium-duty trailer without waiting for an axle that fits.
  • Less road shock! You will maintain the smoothest ride with or without a load.
  • Less danger! An independent suspension gives you better control of your trailer.

The added support of components made from heavy-gauge steel sets you up for a successful, worry-free, off-road and overland experience!

One of the critical components of the HD design are extra reinforcements such as gussets which give your Axle-Less suspension the added strength to withstand the kind of abuse that you’ll encounter on your off-road and overland adventure.

The Axle-Less suspension gives you more creative freedom. Now you have more options to design and build your trailer.

Technical Notes:

Shims are supplied in each Axle-Less HD kit to give you the option to adjust (if necessary) the suspension alignment and camber specific to your trailer frame.

Each hanger comes with a built-in square hole to allow a 2”x3” piece of metal tubing (which can be found at your local hardware store) to act as a cross member, giving extra strength and support. We recommend tubing with a wall thickness of at least 1/8th”.

Most of our Axle-Less HD suspensions use oversized spindles. These spindles will only work with oversized hubs and brakes. 

Polyurethane bushings - used at the pivot point on the control arm - hold the pin firmly in place, resulting in better stability and a more controlled alignment with each moving component. They are weather-resistant and made to last longer, especially in a harsh environment. Furthermore, they’re better able to stand up to the grind of heavy-duty applications.
