A damper for use with an automotive coil over shock absorber. An outer damping sleeve is retained over the exterior surface of an inner body and includes a plurality of bypass ports to alternately align and unalign with bypass ports of the inner body to regulate a bypass flow of damping oil between an interior volume and an outer passage, thereby allowing variable damping control of the damper. The outer damping sleeve is connected to an internal floating piston (IFP) which rides inside the inner body. A control spring is retained for applying a force to the IFP to limit the free movement of the IFP and thereby control a damping force of the damper during the damping event. Increased pressure in the hydraulic damping oil causes the IFP to move, causing the bypass ports to open and close depending on the forces subject to the damper.
