Installation Notes: Some applications may require the lower control arm to be dropped during installation, as the shock body diameter may prevent bottom-up mounting. Certain control arm shock openings may need enlargement to accept QA1 shocks. Stud mounts are measured to the shoulder of the stud; add 13/16 inch for installed compressed length per stud mount.

This Pro Coil system transforms your classic GM muscle car's handling characteristics, delivering modern performance with period-correct aesthetics. The single-adjustable design allows you to fine-tune damping for street comfort or aggressive track use.
