The digressive piston design provides a softer initial response at low shaft velocities while building resistance more aggressively at higher velocities — ideal for track use where precise body control and driver feedback are critical.\u003c\/p\u003e\u003cp\u003eEach kit services a full set of 4 shocks, making it a complete solution for your AST-equipped vehicle.
