Abstract
A suspension system for a vehicle includes a first hydraulic circuit, a second hydraulic circuit and a connection between the first hydraulic and the second hydraulic circuit. The first hydraulic circuit is operatively coupled to a first side of the vehicle, and is selectively controllable to move the first side of the vehicle. The second hydraulic circuit is operatively coupled to a second side of the vehicle, and is selectively controllable to move the second side of the vehicle. The first hydraulic circuit and the second hydraulic circuit operate together in a first mode when the connection between the first hydraulic circuit and the second hydraulic circuit is opened to move the first and second sides of the vehicle in a same direction. The first hydraulic circuit and the second hydraulic circuit operate independently of each other in a second mode when the connection is closed.
