    QA1's Rear Coil-Over Conversion Kit is a bolt-in upgrade for 1978-1988 GM G-Body vehicles. It includes USA made mounting brackets, single adjustable lightweight billet aluminum coil-over shocks, high travel springs and all necessary hardware. Single adjustable shocks offer 18 positions of simultaneous compression and rebound adjustment. The fully threaded shock body allows ride height adjustment, and the shocks are 100 percent dyno tested and serialized and can be serviced and rebuilt by QA1 authorized service centers. The kit lowers the vehicle. Heavier late model vehicles may call for a higher spring rate. Made in the USA.
