QA1's rear suspension system converts 1973-1986 Chevrolet C10 trucks to an adjustable coil-over setup without removing the bed. The bolt-in torque arm design controls suspension movement without the binding common to some four-link systems, for a smooth ride and improved handling. The double-adjustable coil-overs provide roughly 4 to 7 inches of ride height adjustment below stock, so the stance can be set at each corner. Everything needed for installation is included, down to the hardware. Components are made in QA1's Lakeville, Minnesota facility, and every shock is 100 percent dyno tested and serialized.
