XRAY has just released the all-new XB4 center gear diff, replacing the stock slipper assembly. The XB4 gear diff ensures increased on-power steering for nearly all types of tracks, and is ideal for both carpet and clay tracks. The super-smooth gear diff includes a composite case and cover with exchangeable spur gear. The gear diff set includes 81T spur gear and a range of various spur gears is available as an option.
The internal gears are precision-molded from tough XRAY developed composite material, ensuring long lifespan and super-smooth, efficient operation. The maintenance-free diff design will benefit racers of all levels.
XRAY says, “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 our superior sealing system.”
