Product Details

The QA1 RCK52379 is a complete bolt-in rear coilover conversion kit engineered for 1977–1996 GM B-Body full-size cars. Designed as a direct-fit upgrade with no cutting or welding required, this kit transforms the factory rear suspension into a fully adjustable coilover setup capable of handling everything from casual street driving to demanding performance applications.

At the heart of this system are double adjustable aluminum shocks featuring a fully threaded body that allows precise ride height tuning and nearly 5 inches of overall height adjustment. With 18 independent positions of compression adjustment and 18 positions of rebound adjustment, drivers have access to 324 unique valving combinations to dial in the exact handling characteristics needed for any driving condition.

The included 200 lb/in high-travel springs are purpose-built for QA1 Pro Coil systems. Their lightweight construction features fewer coils and a reduced wire diameter, which lowers unsprung weight and improves suspension response speed for better handling performance.

Kit Includes:

  • (2) Double adjustable aluminum coilover shocks
  • (2) 12 in. x 200 lb/in coil springs
  • Specially designed mounting brackets
  • All necessary hardware for bolt-in installation

Key Features:

  • Bolt-in installation — no cutting or welding required
  • Fully threaded aluminum shock body for ride height adjustability
  • 18 compression + 18 rebound positions (324 total valving combinations)
  • 100% dyno tested and serialized at the factory
  • Rebuildable and revalveable by QA1 or QA1 Authorized Service Centers
  • Proudly made in the USA (Lakeville, Minnesota)
  • Compatible with QA1 front coilover kits for a complete suspension upgrade

QA1 Double Adjustable shocks are covered by a Limited Lifetime Warranty. Register at QA1.net/Warranty to ensure coverage for as long as you own your vehicle. Note: Lower shock mount bracket may not be compatible with aftermarket rear end housings.

your checkout page could be simplier/less cluttered

I did not receive mounting hardware and had to buy my own. Chatted with customer service and they said they would inform the warehouse. Nothing happened.

Thank you. The a/c unit arrived a lot quicker to IN than we expected. We were able to install it on the boat the night before we left on a family vacation trip with the boat.

Fast process found the parts I needed

Order five tires and got them in two days great !

Quick and easy search system.
