The unique XRAY Center Active Differential is a high-performance, adjustable gear differential that 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 the XRAY Active Center Differential is 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.
Ball-bearings not included
Notice: When buidling the Active Diff always use all 4 internal satellite gears. Never use only 2 internal satelitte gears.
