Upgrade your C1500 suspension to get the perfect stance.
QA1 C1500 suspension kits are engineered to make your OBS truck handle great while giving you ride height adjustability. Dial in the perfect stance with up to 6" of drop in the front and up to 7" of drop in the rear. Front and rear coil-over suspension kits add modern-day performance and driveability.
Kits include your choice of single- or double-adjustable coil-over shocks. That means you can change the valving to meet your specific needs. Along with a variety of high travel spring rate options, the shocks are 100% dyno tested and serialized. Superior control over suspension movemen helps you easily dial in the stance for a smooth ride and great handling.
Easily bolt in this system – no welding required. Everything is included, all the way down to the hardware. All components in these systems are proudly made in QA1’s Lakeville, Minnesota facility.
