42T Active Center Spur for XB Series Models

The XRAY 355154 Active Center Differential Spur Gear is built for older XB chassis where a reliable 42-tooth center is required. Made from HUDY steel, it balances longevity with accurate tooth profiles.

Material and Heat Treatment Details

This component utilises HUDY steel developed for drivetrain parts and receives a heat treatment that hardens both surface and core to resist pitting and wear under sustained running.

German-Level Machining Quality

Manufactured using precision German equipment, each gear is turned to tight tolerances so the mounting bore and tooth form align cleanly with XRAY differential outdrives.

Laser ID for Easy Matching

The visible "Active 42T" laser mark simplifies identifying the correct replacement part during maintenance or rebuilds.
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.

How do I confirm this is the right 42T for my XB?

Verify tooth count and bore size against your existing part or the XRAY parts list; the 355154 is specified for older XB centre differentials using a 42T spur.

Is surface hardness measured in any way?

XRAY uses a controlled hardening process tailored for HUDY steel to achieve a durable surface while keeping a tough core to avoid brittleness.

Will the laser engraving wear off?

Laser engraving is applied to the gear surface and is resistant to normal use; it may fade only after prolonged abrasion or heavy machining.

Should I match this with a specific diff oil?

Select a diff oil compatible with your XB setup and driving style; the gear itself is neutral to oil choice but correct viscosity helps overall differential performance.
