Auxiliary truck suspensions updated for I-beam axle integration

The RSS-236 suspension has been updated for lighter weight and lower maintenance.


Ridewell Suspensions, Springfield, Missouri, a manufacturer of suspensions for the truck, trailer, bus and RV industries, has updated a self-steer auxiliary truck suspension for I-beam axle integration.

First released in 1997, the RSS-236 suspension has been updated for lighter weight and lower maintenance. The parallelogram design allows customers to integrate their own I-beam axle into the self-steering auxiliary axle suspension.

The RSS-2361000 offers an adjustable frame width and polyurethane bushings.  An integrated air tank kit is available for this suspension.


The RSS-2361000 suspension is designed for single wheel applications (no duals). The suspension is rated for a 13,500 pound capacity; however, the tire and wheel combination used may dictate the suspension’s gross axle weight rating (GAWR).
