Claim:
1. A jounce control damping system comprising: an elongated housing containing a damping medium; a moveable outer piston assembly disposed within the housing; a movable inner piston assembly disposed at least partially within the outer piston assembly; said inner piston assembly being configured to engage a primary piston assembly as said primary piston assembly is moved beyond a first compression movement distance causing the inner piston assembly to move in the compressive direction; and said outer piston assembly being configured not to move in the compressive direction until and after the inner piston assembly moves in the compressive direction beyond a second compressive movement distance, wherein the primary piston assembly provides a first compression damping force during the first compression movement distance of the primary piston; wherein the inner piston assembly provides a second compression damping force during the second compression movement distance of the inner piston assembly and the outer piston assembly provides a third compression damping force greater than the second compression damping force during a third compression movement distance; wherein the damping medium flows through the primary piston assembly, the inner piston assembly and the outer piston assembly; wherein in an initial state the primary piston assembly is not in contact with the inner piston assembly.
