Product Details

The QA1 Precision Products GS401-10550B GM Pro Coil Single Adjustable Coil-Over Conversion System delivers precision suspension control for classic GM A-body vehicles. This complete front coil-over kit features a single adjustable shock with aluminum construction and is engineered specifically for vehicles with 2101-2300 lbs front end weight.

Key Specifications:

  • Single adjustable shock absorber for customizable compression damping
  • 550 lbs/in spring rate for performance handling
  • 10-inch spring free length with tapered flat spring design
  • 9-inch compressed / 12.8-inch extended shock height
  • Stud-type upper mount and T-bar type lower mount
  • Aluminum construction for reduced weight
  • Spring Style "B" configuration

Application Note: Designed for 1968-1972 GM A-body vehicles including Chevelle, Malibu, El Camino, Monte Carlo, Skylark, GS, Cutlass, 442, F85, GTO, Tempest, and LeMans. Some applications may require lower A-arm modification for installation, and certain control arm shock openings may need enlargement to accept the shock body diameter.

Mounting Details: Stud mounts are measured to the shoulder of the stud. Add 13/16-inch for installed compressed length per stud mount. This professional-grade coil-over system provides the adjustability and performance needed for street performance and handling upgrades.
