QA1 Coil-Over And Crossmember Kit for 1963-1972 Chevy C10
Upgrade your classic truck to a modern driving feel and performance. This kit has everything you need to convert your front end to coil-overs and a tubular crossmember with rack-and-pinion steering. It’s a great way to overhaul your suspension in one go, giving you adjustable ride height for the perfect stance with up to 8” of drop. All while dialing in the ride quality and performance level for your application, and saving 140 lbs. of weight vs stock.

Rack and Pinion Steering
Update your truck to a powered rack-and-pinion for quicker steering and a tighter feel. Plus, increase steering angle when fitting larger wheels and tires, and improve your geometry for enhanced drivability. 

Increased Ground Clearance
The crossmember and control arms make your undercab rails the truck’s lowest point for 2” of additional ground clearance. New upper shock mounts increase travel for a great ride and performance, even at low ride heights.

REAR:
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.
