      *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.

      Optimize Performance with a Replacement Coil-Over Conversion

      QA1 Double-Adjustable Pro Coil Systems are ideal for anyone looking for a suspension upgrade that allows for fully-adjustable ride height and valving control while maintaining stock configuration control arms. Choose a spring rate that fits your driving style and provides the stance you want, while offering increased weight transfer, greater durability, and easy bolt-on installation.
