A shock absorber, in an exemplary embodiment, especially adaptable for use on motorcycles and the like vehicles, wherein the shock absorber utilizes a piston member having at least a compression and rebound orifices through which fluid flows, and wherein first and second metering rods are selectively positionable into and out of the compression and rebound orifices respectively control the rate of fluid flow therethrough so as to vary the compression and rebound modes of the shock absorber. The metering rods take the form of co-axial, concentric, needle-like valves extending within a hollow shaft, or the piston rod, wherein each of the metering rods is independently and selectively manipulable and adjustable from an external position of the shock absorber thereby allowing selective manipulation of fluid flow through the piston of the shock absorber, depending upon end results desired with regard to shock absorber function.
