Upgrade the rear suspension of your 1964-1972 GM A-body with the QA1 qapRCK52336 Rear Pro Coil-Over Conversion System. Designed for vehicles such as the Pontiac LeMans and other compatible GM A-body applications, this bolt-in kit includes two double-adjustable aluminum coil-over shocks, high-travel springs with a 150 lb/in spring rate, vehicle-specific mounting brackets, and all required installation hardware. The fully threaded shock bodies provide convenient ride height adjustment without requiring extensive fabrication or modification.
QA1 double-adjustable shocks offer 18 compression settings and 18 rebound settings, creating 324 possible valving combinations for precise suspension tuning. This adjustment range lets drivers optimize ride quality, traction, handling, and control for street performance, drag racing, autocross, road racing, and street rod use. The system can be adjusted from approximately 1/2 inch higher than stock to 2.25 inches lower than stock, helping achieve the desired stance while maintaining suspension performance. Spring selection should account for the vehicle’s overall weight and intended use, particularly on later-model applications that may weigh more.
The QA1 qapRCK52336 system is proudly made in the USA, 100% dyno tested, serialized, serviceable, and rebuildable through authorized QA1 service centers. Its lightweight billet aluminum construction helps reduce unsprung weight while delivering responsive suspension control. Installation is designed as a bolt-in conversion, making it a practical foundation for a complete suspension upgrade when paired with a compatible QA1 front coil-over system. Sold as a pair and backed by QA1’s Limited Lifetime Warranty.
