Disclosed herein is a novel gas permeable internal floating piston specifically designed for installation in the multiple stage air shock whereby the multiple stage air shock is covered in prior patent applications. The multiple stage air shock includes a mixture of oil and gas whereby the mixture provides the shock with emulsion dampening properties. The gas permeable internal floating piston operates by separating the oil from the gas thereby improving the dampening properties of the shock. The permeability of the internal floating piston is based on a membrane that allows the gas but not the oil to pass through the structure of the internal floating piston. The mechanism of the permeability is governed by the creation of a pressure differential across the structure of the internal floating piston, the creation effected with a spring. The membrane features a slow rate of permeation thereby ensuring that the internal floating piston moves in conjunction with the shaft during the operation of the shock.
