Stable Differential for Track-Oriented XB4 Builds

The XRAY 364903 Large Volume Gear Differential Set is built to bring greater stability to XB4 setups by concentrating rotating mass nearer the centreline via its split crown gear. The unit's increased internal oil capacity produces steadier diff response, assisting drivers who need predictable behaviour during extended motos.

Precision-Molded Composite Case

The case and cover are made from XRAY's graphite composite material, providing a robust shell that supports smooth internal motion. Matched with the precision satellite gears, the assembly runs cleanly and requires only routine maintenance to stay race-ready.

Engineered for 2020 XB4 Specification

Specifically tailored to XB4 2020 Specs, this gear differential slips into the standard layout without modification. The reworked diff-outdrives are set up for a 2.5mm pin to ensure a secure and familiar assembly process for XB4 owners.

Specifications

  • Material: Graphite Composite
  • Compatibility: XB4 2020 Specs
  • Pin Size: 2.5mm
  • Design: Split Crown Gear

This XRAY 364903 diff set is a practical upgrade for racers wanting a tougher, more consistent centre diff that helps the XB4 feel more controlled through varied track conditions.
Remark :
Due to limited stock availability, please notice that some XRAY items may have to order from the factory and the ready time is around 4-6 weeks. Customer purchases the item is assumed to accept the waiting time which allows us to order directly from the manufacturer if the item is out of our warehouse.

Will this diff change my XB4's corner exit traction?

The split crown layout and larger oil volume tend to smooth torque transfer, which can lead to more consistent traction on corner exit rather than sudden gains or losses.

Are replacement internal gears available separately?

Replacement parts are typically available through XRAY dealers. Check compatibility with the XB4 2020 Specs when ordering internal satellite gears.

Does the composite case require special diff oil seals?

No special seals are needed beyond standard XB4 diff seals. The XRAY graphite composite is dimensionally stable and works with standard diff seals and oils.
