Product Description

The QA1 52611-S750 is a complete front coilover conversion system for 1963-1987 Chevrolet and GMC C10 pickups, combining QA1's single adjustable coilover shocks with 750 lb/in high-travel springs and upper and lower tubular steel control arms in one bolt-on kit. The coilover shocks provide adjustable ride height and single adjustable valving, allowing you to tailor compression damping to your specific driving style -- from comfortable cruising to aggressive handling. Every shock is 100% dyno-tested and serialized for quality assurance.

The upper and lower control arms are manufactured from 12-gauge HSLA steel tubing and finished in black powder coat, with QA1 performance ball joints and low-friction, maintenance-free polymer bushings at every pivot point. Together, the upper and lower arms provide up to 7 degrees of increased caster for improved straight-line stability and steering feel, along with optimum camber adjustment for a lowered truck. This system is compatible with popular drop spindles, which can provide up to 5 inches of additional drop beyond the coilover adjustment alone -- letting you dial in the perfect stance without purchasing a full chassis or front clip. No welding is required and all necessary mounting hardware is included for a complete bolt-on installation. Made in the USA by QA1.
