Product details
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 QA1 shocks are 100% dyno tested and serialized. Rear suspension system with up to 7" drop for 88-98 C1500 trucks. Includes single adjustable shocks, high travel springs, and adjustable torque arm, trailing arms, panhard bar, and brace bar.
