An anti-cavitation piston for use with shock absorbers is provided. The anti-cavitation piston enables improved damping performance and pressure balance. An embodiment of the anti-cavitation piston includes a two part main piston having a first piston member coupled to a second piston member and additional ports and valving to control damping and reduce or inhibit cavitation during compression and rebound strokes of the shock absorber. Another embodiment of the anti-cavitation piston includes a twin piston device having a first piston and a second piston and additional boost valves, other valving and electronic valving and ports to control damping and reduce or inhibit cavitation during compression and rebound strokes of the shock absorber.

A single valve shock system is described. The single valve shock system includes a single base valve, such as a single semi-active base valve provided between at least one zone of an inner body and a reservoir of the shock. The single valve shock system may also include a refill check valve provided between the at least one zone of the inner body and the reservoir, wherein the refill check valve is in communication with the single base valve to provide the bypass flow to the inner body.
