A shock valve assembly for a hydraulic system includes a fluid path extending between a first port and a second port with a shock valve disposed in the fluid path to normally block fluid flow through the fluid path between the first and second ports. The shock valve temporarily opens to permit fluid flow between the first port and a second port through the fluid path when a fluid pressure differential between the ports exceeds a predetermined threshold. Fluid flow occurs in a first direction from the first port to the second port through the fluid path when the shock valve is temporarily opened and fluid pressure in the first port is greater than the second port. Fluid flow occurs in a second, reverse direction through the fluid path from the second port to the first port when the shock valve is temporarily opened and fluid pressure in the second port is greater than the first port.
