Xray XB4 centre active differential
Xray have introduced their unique centre active differential for the XB4. This high-performance, adjustable gear differential vastly improves the buggy’s speed and handling characteristics. The special design of the internal components, using different angled segments, allows the diff gears to engage on-power to increase forward traction and stability to make the buggy faster and easier to drive. While a performance option for serious racers who want to gain an edge on superior speed and handling, it will also benefit any level of driver that wants a more predictable and easy-to-drive car in any racing conditions.
