QA1 6395-850 63 Series Sealed Aluminum Twin Tube Coil-Over Shock 9in Stroke 5C/850R

The QA1 6395-850 is a 63 Series sealed large body aluminum threaded twin tube coil-over shock absorber featuring a 9-inch stroke, a compressed height of 15.38", and an extended height of 24.30". Mounting is via eyelet top and eyelet bottom (Eye-B/Eye-B), with a compression valving of 5 and rebound valving of 850 and a linear/digressive piston.

The 63 Series is a sealed, non-rebuildable version of QA1's popular 62 Series shock, purpose-built for racing applications. These shocks are most commonly used in coil-over configurations on both dirt and asphalt tracks, and are well-suited as a spec shock for sanctioned series looking to control costs while maintaining consistent performance.

Key Features:
