A method and apparatus for charging a damper with pressurized gas by forming a flow passage between the dust lip of the oil seal and the piston rod. The flow passage is formed by locally deforming the dust lip under the action of a distortion clamp. A source of pressurized gas is then placed in communication with the flow passage. The pressurized gas causes the oil seal to be displaced away from the piston rod, and the gas enters the damper between the oil seal and the piston rod. When the gas within the damper has attained the desired pressure, the distortion clamp is released allowing the dust lip to return to normal circumferential contact with the piston rod, and the source of pressurized gas is removed. The pressurized gas is retained in the damper after charging by the seal engaging the rod.
