Product Description:
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.
Designed for use with QA1 Pro Coil Systems, this system also includes your choice of QA1’s proven single or double adjustable Pro Coil shocks 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 is offered in two options: the first allows for ride height adjustability in two formats: the first allows for ride height adjustability from stock to 4” of lowering without the need of a frame notch, while the second incorporates a bolt-in frame c-notch and allows for up to 6” of total drop.
WHAT'S INCLUDED? Adjustable Shocks, High Travel Springs, Coil-over Hardware, Truck Arms, Panhard Bar, Brace Bar, C-Notch Kit (Optional), All Required Nuts, Bolts, etc.
