Trailer Suspension and Running Gear

Trailer suspension work services leaf springs, hangers, equalizers, bushings, and air ride components. Worn suspension causes tire wear, tracking problems, and additional stress into the frame structure above it.

Suspension wear costs more than the repair

Worn bushings and sagging springs cause tire wear, and tires on a multi-axle trailer are a significant recurring cost. The suspension repair frequently pays for itself in the tires it stops destroying.

Worn running gear also transmits more shock into the frame, which is one of the reasons cracks develop at hanger mounts.
