Product Description

The QA1 RCK52364 Rear Pro Coil Shock System brings modern adjustable coil-over capability to your 1971-1976 GM B-Body Chevrolet Caprice or Impala.

With included 250 lb/in coil springs and double-adjustable shocks, you can fine-tune your rear suspension from comfort-oriented to performance-oriented in minutes. The 12" springs and ride-height adjustability paired with large-wheel clearance capability (up to ~28" wheels) make this kit especially suited for custom and modified builds.

Installation is simplified thanks to the bolt-in design and hardware package - no major fabrication required for compatible axle housings. This makes the QA1 RCK52364 an excellent upgrade for enthusiasts wanting a modern rear coil-over solution in a classic GM B-Body platform while retaining excellent looks, adjustability and road capability.
