The QA1 Proma Star Coil-Over brings coil-over shock performance to a wide range of custom and non-direct-fit suspension builds. This double-adjustable shock has a compressed height of 9-1/2 inches and an extended height of 12-3/4 inches, with bearing eyelet top and bottom (Eye-B/Eye-B). Independent compression and rebound adjustment let ride quality be tuned for the street, drag strip, and road course. The included hardware kit provides quick ride height adjustment, and a correctly rated 2.5 inch spring is added separately to complete the coil-over. QA1 Proma Star shocks are made in the USA, dyno tested, and backed by a Limited Lifetime Warranty.
