Static ride height at the front and rear of the vehicle may be independently adjusted by pumping hydraulic fluid from heave bump hydraulic circuit 33 to heave rebound hydraulic circuit 31 and vice-versa. For both the heave and roll circuits, stiffness may be adjusted by pumping hydraulic fluid equally into the respective hydraulic circuits to compress gas or air in the accumulators to adjust their spring rate.
