    *Notes: Some front applications may require the lower a-arm to be dropped for installation. Body diameter may be too large to allow mounting from the bottom. Some control arm's shock openings may need to be enlarged to accept a QA1 shock.

    Stud mounts are measured to the shoulder of the stud. Add 13/16'' for installed compressed length per stud mount. Loops and t-bars are measured to the center of the loop. Lengths may vary slightly.

    Made in the USA

    The Pro Coil System includes:
  • Two Proma Star single adjustable coil-over shocks
  • Two specially designed conical springs
  • All mounting hardware.

    Easy Bolt-In Installation - Minimal modifications to be made. Remove the existing shocks and springs and the QA1 Pro Coil System bolts right back in.

    Ride Height Adjustable - Threaded aluminum shock body allows ride height adjustment.

    Specially Designed Conical Springs - This spring is designed so that the lower end sets 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 is also achieved by locating the spring pressure in the frame and not on a single stud.

    Features:
  • Easy, Bolt-In Installation - Stock Location Using Stock Mount
  • Lightweight Aluminum
  • Coil-Over Design
  • Ride Height Adjustable
  • 100% Dyno Tested and Serialized
  • Rebuildable and Revalveable Shocks
