Durable 42 Tooth Center Spur for XB Race Cars

The XRAY 355154 Active Center Differential Spur Gear is a spare part aimed at vintage XB race cars needing a robust 42-tooth center spur. Constructed from HUDY steel, it is made to handle regular club and track use.

Robust Material with Controlled Hardening

HUDY steel is chosen for its gear-friendly properties and is subjected to a specific hardening schedule to strengthen the surface while preserving core toughness for impact resistance.

High Precision Manufacturing Process

Precision machining on German equipment ensures consistent tooth geometry and bore accuracy, which helps reduce unwanted backlash and improves drivetrain smoothness.

Identification Marking by Laser

The gear includes a laser-etched "Active 42T" label to help you quickly identify the correct item during rebuilds or spares checks.
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.

Can I fit this to a modern XB without modification?

Some modern XB variants may use different centre sizes; compare the bore and tooth count before fitting and consult parts diagrams if unsure.

What maintenance keeps the gear working well?

Keep mating gears clean, check mesh regularly, and replace bearings or diff outdrives showing play to preserve gear life.

Is there a recommended mounting procedure?

Fit the gear with correct shims if needed, ensure the differential is seated correctly, and verify smooth rotation before full-power runs.

Are upgrades available for the rest of the drivetrain?

Yes, consider higher quality bearings, hardened outdrives, or improved diff oils to complement a new spur gear and enhance drivetrain reliability.
