QA1 64-72 GM A/G-Body Pro Rear Coil-Over System - MOD Series - 12in x 175lbs/in - Aluminum - RCK52442

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.
