QA1 RCK52442 Rear Pro-Coil MOD-Adjustable Coilover Kit 64-72 GM A/G-Body 14" 175lb/in

The QA1 RCK52442 Rear Pro-Coil MOD-Adjustable Coilover Kit is a complete rear suspension upgrade designed for 1964–1972 GM A-Body and G-Body vehicles. This kit replaces the factory rear shock and spring setup with a modern coilover system, delivering improved handling, adjustable ride height, and performance tuning capability straight from the box.

At the heart of this kit are QA1's MOD Series shocks, which feature tool-adjustable damping so you can dial in the ride and handling characteristics to match your driving style — whether that's street cruising, road course work, or weekend performance driving. The included 14-inch coilover springs are rated at 175 lb/in, providing a firm yet controlled spring rate well suited for performance street and light track applications.

Kit Includes:

• Two (2) QA1 MOD Series rear shock absorbers
• Two (2) 14-inch coilover springs — 175 lb/in spring rate
• Mounting brackets and all necessary hardware for a complete installation

Key Features:

• MOD Series adjustable damping — single-adjustable shock for on-the-fly tuning

• Bolt-on installation with included brackets and hardware — no cutting or welding required
• Designed specifically for 1964–1972 GM A-Body and G-Body platforms
