Product Details

The QA1 Precision Products GS401-10450C is a front Pro Coil single adjustable shock kit designed for GM stock mounting applications. This complete kit delivers precise suspension tuning with professional-grade components built for performance and durability.

Key Features:

  • Single adjustable design allows for fine-tuning of compression damping
  • Aluminum construction for reduced weight without sacrificing strength
  • Compressed length: 8.63 inches
  • Extended length: 12.88 inches
  • Includes 10-inch coil spring with 450 lb/in spring rate
  • Large tapered flat spring end configuration for secure mounting
  • GM stock mount compatibility for direct bolt-on installation

This kit provides enthusiasts and racers with the adjustability needed to dial in their suspension for street, strip, or autocross applications. The aluminum shock body reduces unsprung weight while the single adjustment valve allows for precise tuning to match driving style and track conditions.
