Abstract: A shock absorber assembly including: a cylinder housing a first damper fluid and a first piston, the first piston extending out from within the cylinder; a top mount in cooperation with a distal end of the first piston; and a hydraulic jounce control damper adjacent to the top mount, the hydraulic jounce control damper defining a jounce chamber including a second damper fluid and a second piston extending out from within the jounce chamber. In response to compression of the shock absorber assembly, the second piston is configured to contact the cylinder and slide within the jounce chamber with movement of the second piston dampened by the second damper fluid.
