Product Details

The QA1 GS401-10600B Pro-Coil System is a stock-mount front coilover conversion kit designed for GM vehicles. This complete bolt-in system replaces the factory coil spring and shock setup with a fully adjustable coilover assembly, allowing precise ride height and damping control without requiring any permanent modifications to the factory mounting points.

The kit features QA1's single-adjustable aluminum shock bodies, which provide rebound damping adjustment to tune handling and ride quality to your specific application. The shocks are paired with 10-600 rate tapered flat springs, engineered to work in harmony with the shock valving for optimal performance on the street or strip.

Key Features:

  • Stock-mount front coilover conversion — no frame or crossmember modifications required
  • (2) QA1 single-adjustable aluminum-body shocks with external rebound adjustment
  • (2) Specially designed 10-600 lb/in rate tapered flat coil springs
  • All necessary mounting hardware included for a complete installation
  • Allows ride height adjustment through spring perch positioning
  • Lightweight aluminum shock bodies reduce unsprung weight
  • Designed as a direct replacement for OEM front spring and shock components

The QA1 Pro-Coil System is the ideal solution for GM muscle car and performance vehicle owners looking to modernize their front suspension with a proven coilover setup while retaining the factory mounting locations. QA1 Manufacturer Part Number: GS401-10600B.
