QA1 1963-87 C10 Front Coilover Conversion Systems
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.
