    Update Your GM Front End with a Stock Mount Coil-Over Conversion System from QA1!

    QA1 Single Adjustable Pro Coil Systems are great options for anyone looking for fully adjustable ride height and valving control while maintaining stock configuration control arms. Choose a spring rate that fits your driving style and adjust the valving to match, and you're on your way. This system is a great option for anyone looking for a suspension upgrade for their street car. With 18 valving options of simultaneous compression and rebound adjustment, the QA1 Single Adjustable Pro Coil System allows for that soft comfortable ride you want when cruising and the firm handling you'd expect from a more modern sports car.
    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





    GM Pro Coil Coil Over Conversion Kits are also available in Double Adjustable and Drag Race "R" Series
