A hydraulic damper with one end connected to the body of a vehicle and a second end connected to a suspension system of a vehicle. The mechanism allows for multiple hydraulic-fluid metering valve positions to control piston resistance based on a variable pressure input using pressurized gas. The use of compressed gas to mechanically control a valve position allows changes to the piston resistance to be made quickly and to be increased or decreased as desired. The hydraulic damper features a control piston which in turn mechanically controls a valve needle within a hydraulic suspension piston. The position of the valve needle controls the damping characteristics of the suspension piston. When the control piston moves, the position of the valve needle is proportionally adjusted.
