Description

Rear coil-over conversion kit for 1973-1987 C10 trucks. Includes single adjustable shocks, high-travel springs, and all necessary hardware.

The adjustable coil-over system offers 4" to 7" of ride height adjustment below stock. Can be paired with QA1's front system for four-corner ride height adjustability. All components are made in QA1's Lakeville, Minnesota facility. All QA1 shocks are 100% dyno tested and serialized.
