The QA1 bolt‑on rear suspension system for 1963–1972 Chevrolet C10 trucks converts factory coil springs to adjustable coil‑overs and offers up to 6" of total drop. The kit includes double‑adjustable shocks, high‑travel springs, adjustable tubular truck arms with integrated pinion angle adjustment, a panhard bar and brace hardware. Coil‑overs relocate outside the frame for improved cornering and the system installs without removing the bed.
