Pro-Coil Rear Shock Kit 64-72 GM A/G-Body

The QA1 Pro-Coil Rear Shock Kit for 64-72 GM A-Body and G-Body vehicles is a double-adjustable coil-over suspension system designed to deliver independent control over compression and rebound damping. This pair of rear shocks features a 150 lb/in spring rate and twin-tube construction, providing the foundation for handling refinement on classic muscle cars, street rods, and daily-driver restorations where suspension geometry and ride quality demand modern engineering.

The 150 lb/in spring specification sits in the sweet spot for street and light road-course use on first-generation A-Body and G-Body platforms, offering compliance over rough surfaces while resisting body roll during cornering. Twin-tube damper design provides consistent heat dissipation during extended driving, while the double-adjustable valving permits independent tuning of low-speed (weight transfer) and high-speed (bump absorption) damping circuits. This separation allows drivers to dial in comfort during normal cruising while maintaining control during aggressive suspension articulation.

Buyers restoring or upgrading 1964–1972 Chevrolet A-Bodies (Chevelle, Nova, Malibu) and G-Bodies (Skylark, GS, Regal) will find this kit suited to builds prioritizing handling balance without excessive stiffness. The rear-only configuration pairs with existing or upgraded front suspension systems, making it ideal for staged suspension builds or shops seeking OE-mounting simplicity with adjustable performance. Proper installation requires familiarity with spring preload and damper adjustment procedures; QA1 products are engineered to industry standards for coil-over suspension systems.
