QA1 1988-98 C1500 Rear Coilover Conversion Systems

QA1 1988-98 C1500 rear coilover conversion systems are a great upgrade to your C1500 suspension. Each kit comes with QA1’s proven 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 C1500 torque arm suspension with C-notch bracket is manufactured from 12-gauge HSLA steel tubing for increased strength and powdercoated for long-lasting durability. Systems come complete with adjustable instant center, panhard bar, and pinion angle to allow you to adjust the system to your exact needs. This easy bolt-on kit will add more stability and allows for optimum camber adjustment in a lowered truck. Everything needed is included, all the way down to the hardware; no welding or bed removal required.
