    Do you have a high-performance street/strip GM? The QA1 Double Adjustable Pro Coil System is the most versatile direct bolt-in front suspension on the market. No cutting or welding... these coil-over systems are designed to work with stock suspension and stock control arms (mounting bolt/nut assembly modification may be required).

    Take control of your vehicle's ride height, and get the stance you want with double adjustable valving that allows simple switching between one type of driving to another. Unlike many other shocks, the valving between compression and rebound can be adjusted independently. 18 positions of rebound on one knob and 18 positions of compression on the other knob, providing 324 valving options.

    The Pro Coil System Includes:

    • Two Proma Star double 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.
