The Spohn Performance single adjustable rear coil over conversion kit for the 1965-1996 Impala, Caprice, Biscayne, Bel Air, etc.

This kit is based on the QA1 Proma Star 18 way single adjustable aluminum coil over shocks:

  • 18 Positions of Shock Adjustment: Simultaneous compression and rebound adjustment with 18 valving options. Unique to QA1, one knob changes both compression and rebound valving simultaneously, allowing total suspension control in one easy-to-reach location.
  • Deflective Disc Valving: Advanced shock technology, increased sensitivity in valving response, control and consistency.
  • Precision Machined Piston with PTFE Piston Band: Creates accurate piston to cylinder wall seal, improves valving consistency and increases durability.
  • 5/8" Centerless Ground, Hard Chrome Plated, Solid Piston Rod: Precision surface, eliminates piston rod flex increasing valving consistency.
  • Forged, Machined Aluminum Body: Lighteweight, stronger than billet. Bright anodized for unmatched durability and great appearance.
  • Three Step Sealing System: Advanced aerospace material, exclusive double lip seal design and wiper seal eliminate seal drag and dirt intrusion.
  • 100% Dyno Tested and Serialized: Assures consistency in production and performance.
  • Spring Mounting Hardware Included: Aluminum spring cap, spring seat, and locking ring included.
  • Top Shock Mounting: Polyurethane bushings with extreme duty CNC machined t-bars.
  • Bottom Shock Mounting: Exclusive Teflon/Kevlar race bearings for smooth bind-free operation.
  • Ride Height Adjustment: Set your ride height to the exact height you want it to be.
