XRAY X4 Gear Differential - Set

The front solid axle and rear differential feature updated designs to move the belt positions closer to the center. By moving the belts closer to the center line of the car, the forward traction and efficiency is greatly improved, which is beneficial in both stock and modified classes.

The X4 gear diff produces the on-power steering that is needed on nearly all types of tracks, and is ideal for both carpet and asphalt tracks.

The gear diff includes a composite case and cover with the integrated pulley. The internal gears are precision molded from tough composite material and combined with aluminum drive shaft adapters to create a light and super-smooth differential.

Another key advantage of the gear diff is that it is virtually maintenance-free. When the diff is correctly built, there is no need for maintenance for a very long time… no need for frequent oil changes, and no leakage due to the superior sealing system.
