Lightweight Graphite Differential Cover for XRAY XB4

The XRAY 364920-G graphite composite gear differential cover is a precision machined upgrade made for the XB4 range. Built from a tuned graphite composite, it balances rigidity with low mass to help improve diff response and reliability under race stress.

Durability and Thermal Stability

This cover uses a graphite composite that stands up to heat and wear while trimming overall component weight. The material helps maintain clamped assemblies and reduces the chance of screw loosening during prolonged track use. Its larger internal volume also aids consistent diff behaviour during hard runs.

Designed Specifically for XB4 2020 Fitment

Made to match XRAY XB4 2020 geometry, the 364920-G drops into place without modification for a clean upgrade path. It lets you replace the stock cover quickly so you can focus on setup and track time.
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 364920-G compatible with older XB4 variants?

This cover is engineered for the XRAY XB4 2020 specification and is not guaranteed to fit other model years without modification.

What advantages does the graphite composite provide?

Graphite composite offers a high strength-to-weight ratio, improved heat resistance, and better wear characteristics compared with many plastics.

Any tips for installation and maintenance?

Use the original hardware and follow XRAY recommended tightening practices. Inspect screws after a few runs and apply a light threadlocker if you race hard regularly.
