A hydro-pneumatic suspension system 10 and a method for an off-road vehicle are provided. The suspension system 10 is operable with a hydraulic cylinder 50 defining a piston side 52 and a rod side 56 configured to receive fluid from a pump 12. The suspension system 10 comprises: a proportional rod control valve 26; a piston control valve 24; a pilot operated check valve 66; a blocking valve 60; and a controller 40 configured to control a stiffness of the suspension system to maintain a target natural frequency for the vehicle.
