QA1 RCK52450 Kit, Rear Pro-Coil MOD-Adj, 78-88 GM G-Body, 12-220

Don't be limited to adjustments! Completely re-valve in minutes with the MOD Series shock. Designed specifically to meet the demands required by today's high performance drag race and handling/pro-touring cars QA1's multi-patent-pending MOD Series shock will transform the way racers respond to changing track conditions and configurations. The key element to this tunability is QuickTune Technology: dry modular valve packs that can easily be swapped out all while the shock remains on the car. An industry first the MOD Series shock can quickly and easily be revalved without interrupting the oil path or opening the shock up for debris and air contamination. Medium compression and rebound valve packs come standard; soft or firm compression and rebound valve packs also available. Once the desired valving is in place the unique double adjustable design with adjustable low-speed bleed allows for fully independent control over the compression and rebound characteristics. With all these adjustability options the MOD Series shock achieves an expansive force curve capability and an unprecedented level of tunability. The shock also features mounting adjustability to accommodate a variety of vehicles and mounting configurations. The nitrogen-charged canister is available in a piggyback or remote configuration for ease of installation in tight areas and the base eyelet is indexable so you can unbolt it and reattach it at the angle you need for the best shock and canister placement. Like all QA1 shocks the MOD Series shock is 100% dyno tested and serialized and proudly made in QA1's Lakeville Minnesota facility.
