QA1 Aluma Matic coilover shocks provide a great ride and good looks. These shocks feature a compression-biased valving system that uses shaft speed control to vary the resistance in the shocks. The result is ride-sensitive handling and outstanding control for the street or strip. Plus, they include a 5/8 in. centerless ground chrome piston rod, a clear anodized aluminum body, number 8 Acme threads for quick ride height adjustments, aerospace sealing materials, and polyurethane mounts.
