Product Details

The QA1 Precision Products GS401-10350C Pro Coil Single Adjustable Coil-Over Conversion System transforms your GM A-body front suspension into a high-performance adjustable setup. This complete kit features QA1's proven single-adjustable shock technology paired with precision-matched coil springs for superior handling and ride quality customization.

Key Specifications:

  • Single adjustable shock absorber with 9-inch compressed / 12.8-inch extended height
  • 10-inch free length coil spring with 350 lbs/in spring rate
  • Engineered for 1700-1801 lbs front end weight applications
  • T-bar type lower mount configuration (Style C)
  • Tapered flat large spring design for aluminum construction
  • CNC-machined aluminum components for weight savings and durability

Installation Notes:

  • Some applications may require lower A-arm to be dropped during installation
  • Control arm shock openings may need enlargement to accept QA1 shock body diameter
  • T-bar mounts are measured to center of the loop; actual lengths may vary slightly
  • Professional installation recommended for proper suspension geometry

This conversion system delivers race-proven performance with street-friendly adjustability, allowing you to fine-tune your suspension for everything from daily driving to autocross competition. The single-adjustable design provides 12 clicks of compression and rebound damping adjustment to dial in your perfect ride.
