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

QA1's C10 Front Pro Coil Systems 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. These 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 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 uses only a bracket instead of an upper control arm for those on a budget, which will add 3-4 degrees of caster while providing ride height adjustability with coil-over shocks. The tubular upper control arm can be added later for additional strength, camber adjustment, and caster. Must use spindles compatible with 73-87 ball joints. Made in the USA.
