  Description: "R" Series 90-10 Pro Coil Systems w/Adjustable Shocks

Direct Bolt-In Installation:

  • No modifications to be made. Remove the existing shocks and springs and the QA1 Pro Coil System bolts right in.

Ride Height Adjustable:

  • Directly threaded aluminum body allows ride height adjustment. Bright anodizing increases body strength and durability

Specifically Designed Conical Springs:

  • The Spring is designed so that the spring sits on the coil-over shock and the upper end sets in the original spring bucket in the frame. This allows for the use of a longer and lighter spring for more stored energy, offering increased weight transfer. Greater durability and safety is also achieved by locating the spring pressure in the frame and not on a single stud.

Additional Features:

  • Provides unmatched performance for stock GM front ends
  • 90-10 valving
  • Fixed compression with a wide range of rebound adjustment
  • Easy Bolt-in installation
  • Kit includes - (2) Proma Star Shocks, (2) Specifically designed conical springs and mounting hardware.
  • 100% dyno tested and serialized
  • Made in the USA
