Product Details

The QA1 Precision Products GS401-10550A is a complete Pro Coil front coil-over conversion system designed for GM A-body vehicles including 1967-1969 Camaro and Firebird, 1968-1974 Nova and Chevy II, and 1973-1974 Omega models. This single adjustable coil-over kit features aluminum construction with a tapered pigtail spring configuration for improved handling and ride quality.

Key Specifications:

  • Spring Style "A" configuration for GM A-body applications
  • Single adjustable shock with 9-inch compressed and 12.8-inch extended length
  • 10-inch free length spring with 550 lb/in spring rate
  • Designed for 2101-2300 lbs front end weight
  • Stud type upper mount and T-bar type lower mount
  • Aluminum construction for reduced unsprung weight

Installation Notes:

  • Some front applications may require dropping the lower A-arm for installation due to shock body diameter
  • Control arm shock openings may need enlargement to accept QA1 shocks
  • Stud mounts are measured to the shoulder of the stud; add 13/16 inch for installed compressed length per stud mount
  • T-bar mounts are measured to the center of the bar

This complete coil-over conversion system provides adjustable damping control to fine-tune your suspension for street performance, handling, or track use. The single adjustable design allows you to dial in compression and rebound damping simultaneously for optimal suspension tuning.
