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 21T suitable for street and carpet tracks?

The 21T is versatile and works well on medium-speed layouts including many carpet tracks and tight outdoor circuits. Fine tuning with neighbouring sizes helps dial in performance.

How does hard coating affect longevity?

The hard coat improves surface wear resistance under normal use, helping to maintain tooth profile longer than untreated aluminium parts.

What checks should I do after fitting a new pinion?

After fitting, verify mesh and free spin, then run the car briefly and recheck mesh and thread security. Inspect teeth for correct contact pattern.
