Torsion Suspension System
1. The Lippert Components, Inc. Torsion Suspension system is designed to offer superior qualities over
leaf spring technology. The Lippert Components, Inc. Torsion Suspension system is bracketed to the
trailer’s frame and housed inside the trailer axle’s tube.
2. The spindle is connected to a swing arm, the swing arm is connected to a square inner bar that is
sheathed in rubber and as the swing arm rotates and experiences the torque and resistance of driving
conditions, the characteristics of the rubber absorb and distribute the load providing benefit over leaf
spring suspensions.
3. The Lippert Components, Inc. Torsion Suspension system requires very little attention in regards to
maintenance. Normal inspection of the entire Lippert Components, Inc. Trailer Axle system can be
applied to the Torsion Suspension system. See inspection procedures for system components in this
manual.
