The QA1 GM Pro Front Coil-Over System is a bolt-on front coil-over package built around the QA1 MOD Series double-adjustable shock for the 1970-1981 Chevrolet Camaro and Pontiac Firebird. The MOD Series uses QuickTune dry modular valve packs that can be swapped to change valving without opening the shock, and it offers independent 4-way adjustment of high-speed and low-speed compression and rebound for a wide, tunable force curve. The nitrogen-charged canister mounts in a remote or piggyback configuration for installation in tight areas, and each shock is 100 percent dyno tested and serialized. The system includes a 10 inch, 450 lb/in coil-over spring.
