A vehicle suspension system for use with a vehicle includes a first hydraulic cylinder, a second hydraulic cylinder, and a fluid circuit. The first hydraulic cylinder and the second hydraulic cylinder each include an upper chamber and a lower chamber. The fluid circuit is hydraulically coupled to the first hydraulic cylinder and the second hydraulic cylinder and includes a valve that is movable between a first position and a second position. When the valve is in the first position, the upper and lower chambers of each hydraulic cylinder are hydraulically coupled to the opposite chamber of the other cylinder. When the valve is in the second position, the upper chamber of each hydraulic cylinder is coupled to the lower chamber of the same cylinder. The valve is configured to move between the first position and the second position in response to manual input.
