Abstract
A shock absorber is provided having a cylinder, a piston rod, a piston body, and a valve. The cylinder is configured to receive fluid. The piston body is connected to the piston rod and is configured to reciprocate within the cylinder between a compression chamber and a rebound chamber. The valve is provided by the piston body having a fluid flow port, a valve seat, a circumferential valving element, and a spring configured to urge the valve body into the valve seat. A primary damping valve and an auxiliary damping valve are also provided.
