This QA1 35mm circle track shock piston is built for QA1 large body twin tube shocks. These twin tube shocks respond quickly when the shock changes direction, and two check ball ports provide independent compression and rebound bleed circuits for precise low-speed control. This piston uses a 1.5 degree linear configuration.
