Description

IMPORTANT NOTICE: Must use spindles compatible with 1973-87 ball joints. Not for use with factory sway bars.

QA1 1963-87 C10 front coilover conversion systems are a great upgrade to your C10 front suspension. Each kit comes with QA1's proven single or double adjustable coilover shocks—so you can change the valving to meet your specific needs—along with a variety of spring rate options. These shocks allow for ride height adjustability and are 100 percent dyno-tested and serialized. The QA1 C10 upper and lower control arms are manufactured from 12-gauge HSLA steel tubing for increased strength and are powdercoated for long-lasting durability; they're topped off with performance ball joints and low-friction, maintenance-free bushings. These kits will add up to 7 degrees of caster for more stability, and allow for optimum camber adjustment in a lowered truck. For those on a budget, QA1 also offers kits without the upper control arm—which will add 3-4 degrees of caster, while still providing ride height adjustability with coilover shocks. Order the model designed for your vehicle application.

Product Overview

With adjustable ride height and up to 5? drop with the use of popular drop spindles, these front control arm suspension kits for 63-87 C10 trucks help you find the right stance without the expense of buying a chassis or full front end. The coil-over shocks are offered in single or double adjustable valving options and come with high travel springs available in three spring rate options. The upper and lower control arms together provide up to 7 degrees of increased caster for more stability and driveability. This front coil-over conversion kit includes upper and lower control arms, double adjustable shocks, high travel springs, upper bracket, and all hardware.
