QA1 Complete Rear Double Adjustable Coilover System - 63-72 C10

QA1’s C10 bolt-on rear suspension system is designed to convert trucks originally equipped with a coil-spring rear suspension to coil-overs. Made in the USA, this system relocates the coil-overs to the outside of the frame rail, closer to the wheel, providing more cornering stability and allowing room for popular aftermarket rear fuel tanks. The factory truck arms are replaced with a 7 gauge DOM steel tubular design with an integrated pinion angle adjustment, eliminating the need for angled shims, and feature QA1’s X Series self-lubricating rod ends. With the adjustable length truck arms, you can set the wheelbase to your exact specifications. The adjustable mounts allow for optimum anti-squat. A full-length, adjustable panhard bar with multiple mounting locations corrects roll center geometry for the desired amount of drop.

This system also includes your choice of QA1’s proven single or double adjustable Pro Coil Systems so you can change the valving to meet your specific needs. Available with three options of high travel spring rates, these shocks allow for ride height adjustability and are 100% dyno tested and serialized.

This C10 rear suspension system incorporates a bolt-in frame C-notch and allows for up to 6” of total drop.
