Ridewell’s new RSS-233 offers a completely new design for a steerable auxiliary lift axle suspension system.

The new design features a compact mounting envelope and easy mount, adjustable hanger system. This suspension also ships fully assembled for efficient installation, Ridewell said.

RSS-233 suspensions are manufactured with a dual draw key kingpin design to extend kingpin life and fully cast axle ends for increased strength and durability.

Additionally, the suspension features a ride height of 7 ft., 18 in., a 13,200-lb. capacity, pre-plumbed air tank option, polyurethane pivot bushings and angled control arms for lateral stability.

There is also a 1 in. and 2 in. spacer kit option.
