Ideal for trucks that will see track time or for drivers who demand the best in ride quality and handling, our Double-adjustable Pro Coil shocks are the right choice for you.

HEAVY DUTY SHOCK DESIGN

QA1 Engineers have tackled the challenge of supporting the weight and payload capacity of modern trucks by designing a heavy-duty version of our Pro Coil system, which features an upgraded shock with polyurethane bushings and a 1" chromoly T-bar. The system's new bushing design was specifically chosen to withstand the daily use of trucks, rather than using spherical bearings.
