The XB4 gear diff ensures increased on-power steering which is needed on nearly all types of tracks, and is especially ideal at carpet and clay tracks. Designed for use with 2.5mm pin. The stronger diff outdrives are the result of a new hardening process that increases lifespan and reliability.
The super-smooth gear diff includes a composite case and cover with integrated crown gear. The internal gears are precision-molded from tough XRAY developed and mixed composite material ensuring long lifespan and super-smooth & efficient operation.
The maintenance-free diff design will benefit racers of all levels. 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.
