Jounce bumpers are typically 40 to 120 millimeters in length. They enable ride tuning and are active in medium load events. Jounce bumpers need a soft entry fee and support increasing loads at 50 percent travel. They are active in fully loaded vehicles and support maximum jounce loading. MCU-Jounce bumpers from Vibracoustic can be used as a replacement for the traditional metal to metal stop.
