QA1 63-72 Chevrolet C10 Rear Suspension Conversion System - Medium - Single Adjustable (200lbs/in)

This QA1 C10 bolt-on rear suspension system is designed to convert trucks originally equipped with a coil-spring rear suspension to coil-overs. It relocates the coil-overs to the outside of the frame rail for improved cornering stability and provides room for aftermarket rear fuel tanks. The system replaces factory truck arms with 7 gauge DOM steel tubular arms that feature an integrated pinion angle adjustment, eliminating the need for angled shims. It also includes QA1's X Series self-lubricating rod ends. The adjustable length truck arms allow for precise wheelbase setting and the adjustable mounts enable 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 includes a choice of QA1’s single or double adjustable Pro Coil Systems, allowing for valving changes to meet specific needs. Available with three options of high travel spring rates, these shocks offer ride height adjustability and are 100% dyno tested and serialized. The C10 rear suspension system incorporates a bolt-in frame C-notch and allows for up to 6” of total drop.
