Will this diff suit high speed track running?

Yes, the lower rotating mass of the XRAY 364903-L helps the XB4 2026 stay stable at speed and respond more quickly to steering changes, which benefits fast circuits.

What maintenance does it need after racing?

Inspect the gears and bearings for wear and clean out old lubricant after running. Refill with the recommended diff oil and check for play in the output shafts.

Can I fit this to an XB4 without other changes?

The unit is made for the XB4 2026 platform; in most cases it installs as a direct replacement. Verify existing hardware and follow the XB4 service manual for torque settings.
