The QA1 RCK52463 is a Rear Pro Coil MOD Series coilover conversion kit designed for 1977–1996 GM B-Body vehicles equipped with big wheels.

• Medium compression and rebound valve packs included as standard; soft and firm packs available separately for expanded tuning range
• Nitrogen-charged canister available in piggyback or remote configuration for installation flexibility in tight spaces
• Indexable base eyelet allows repositioning for optimal shock and canister placement
• 100% dyno tested and serialized at QA1's Lakeville, Minnesota facility
• Specially designed USA-made mounting brackets included for a bolt-in installation

Kit Includes:

• QA1 MOD Series rear shocks (springs not included)
