Product Details

The QA1 RCK52370 is a bolt-in rear coilover conversion kit engineered for 1973–1977 GM A-Body vehicles. This springs-not-included version is ideal for builders who want to select their own spring rates or already have QA1 Pro Coil springs on hand. The kit pairs two double-adjustable Proma Star aluminum shocks with specially designed USA-made mounting brackets and all necessary hardware for a complete rear suspension upgrade.

QA1's double-adjustable shocks deliver 18 positions of independent compression adjustment and 18 positions of rebound adjustment, yielding up to 324 unique valving combinations. This allows precise tuning for everything from daily street driving to competitive track applications without compromise.

The fully threaded aluminum shock body works in conjunction with the included adjustable mounting brackets to provide easy ride height adjustment — fine-tuning weight balance and stance without cutting or welding.

Key Features:

  • Double-adjustable valving: 18 compression + 18 rebound positions (324 combinations)
  • Bolt-in installation — no cutting or welding required
  • Fully threaded aluminum shock body for ride height adjustability
  • Ride height range: approximately 1" above stock to 3" below stock
  • 100% dyno tested and serialized at the factory
  • Rebuildable and revalveable by QA1 or QA1 Authorized Service Centers
  • Proudly made in the USA
  • Springs not included — purchase QA1 Pro Coil springs separately

Kit Includes:

  • 2 Double-Adjustable Proma Star Aluminum Shocks
  • Specially designed mounting brackets
  • All necessary installation hardware

QA1 double-adjustable shocks are eligible for a Limited Lifetime Warranty. Register at QA1.net/Warranty after installation to ensure coverage.
