Long-lasting Composite Spur for Reliable Drivetrain

The XRAY 364981 Composite Center Differential Spur Gear is built to improve drivetrain behaviour in compatible RC models. Its 81-tooth layout promotes smooth power delivery and consistent mesh under load. Manufactured from a purpose-formulated composite, it balances toughness with low mass to reduce rotating weight. The tooth count is clearly marked to speed up maintenance and gear swaps.
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.

Which cars accept an 81T centre spur gear?

This part fits RC models that specify an 81-tooth center spur in their drivetrain layouts. Always confirm compatibility with your chassis manual and check pinion alignment before running.

Will the composite material hold up to regular racing?

The composite is chosen for wear resistance and impact tolerance, so it performs well under typical club racing conditions when gear mesh and diffs are set correctly.

How should I inspect the spur for wear?

Look for rounded or chipped teeth, inconsistent contact across the tooth face, or unusual noise. Replace the spur if you see visible damage or performance drop.
