XRAY have introduced new large volume composite graphite center differential case and cover only designed for the XB4’20. The large volume rubber-sealed differential case is made from specially-formulated graphite composite material. Thanks to his lighter and tougher material with higher temperature and wear resistance, also holds the screws better secured in place.

The large volume rubber-sealed differential cover is also made from specially-formulated graphite composite mixture for increased strength and lower weight, offering a perfect balance between reliability and performance.
