QA1 now offers front control arm suspension kits including QA1's Pro Coil System and control arms to upgrade your C10 front suspension.
These kits include your choice of QA1's proven single or double adjustable coil-over shocks so you can change the valving to meet your specific needs, along with a variety of high travel spring rate options. The shocks allow for ride height adjustability and are 100% dyno tested and serialized. Coil-over hardware and all required nuts, bolts, etc. are included. Compatible with popular drop spindles, which will provide even more drop when used with this system.
QA1's C10 upper and lower control arms are made of 12 gauge HSLA steel tubing for increased strength and are powder coated for long lasting durability. They feature QA1 performance ball joints and low-friction, maintenance-free polymer bushings for added performance. This kit adds up to 7 degrees of caster for more stability and allows for optimum camber adjustment in a lowered truck.
Kits must use spindles compatible with 73-87 ball joints. Made in the USA.
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.
