Description

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.

Product Overview

Add modern performance to a pickup that was designed for utility ? all without removing the bed of the truck. QA1 engineered a unique design offering 4" to 7" drop that maximizes performance without the inherent binding issues of other 4-link systems. With superior control over suspension movement, you can easily dial in the stance for a smooth ride and great handling characteristics. The systems come with unprecedented adjustability: the panhard bar, torque arm, trailing arms, bracket mounts, and shocks are all adjustable, and they are truly independent of each other, so you don?t have to worry about one adjustment affecting another. Easily bolt in this system ? no welding required. Everything needed is included, all the way down to the hardware. All components in these systems are proudly made in QA1?s Lakeville, Minnesota facility. All QA1 shocks are 100% dyno tested and serialized.
