Track-Grade Centre Differential for XB4 Performance

The XRAY 364903 Large Volume Gear Differential Set is aimed at drivers who want steadier centre behaviour from their XB4. The split crown gear design repositions rotating mass nearer the centreline to aid balance, while the larger oil chamber moderates diff response for repeatable handling across sessions.

High-Strength Graphite Composite Construction

The differential housing and cover are produced from XRAY's graphite composite, offering a balance of strength and low friction. The internal satellite gears complement the housing to keep operation smooth and reduce the need for frequent servicing.

Compatibility with XB4 2020 Specs and Pin Size

Engineered to match XB4 2020 Specs, this gear differential fits into the existing mounting points and drivetrain layout. The diff-outdrives are sized for a 2.5mm pin, matching standard XB4 pin fittings for straightforward installation.

Specifications

  • Material: Graphite Composite

For racers and club drivers looking to refine handling without complex mods, the XRAY 364903 provides a durable and consistent centre diff option tailored to the XB4 platform.
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.

Is the XRAY 364903 suitable for weekly club racing?

Yes, the durability of the graphite composite and the steady diff behaviour make it well suited for regular club racing where consistent performance matters.

Can I tune handling with oil choice in this larger-volume diff?

Yes, changing diff oil weight will alter response. The larger volume provides a more predictable starting point, making oil changes an effective tuning step.

Will this diff fit older XB4 variants?

The XRAY 364903 is designed for XB4 2020 Specs. Compatibility with older variants is not guaranteed and should be checked against the older diff housing and outdrive interfaces.

How often should I inspect the internal gears?

Routine checks after several race days or if you notice changes in diff feel are recommended. Inspect satellites and seals for wear and refresh oil as part of regular maintenance.
