High Precision 21T Pinion for Driven Stability

The XRAY 348521 XCA Aluminium Pinion Gear is crafted to sharpen your vehicle's drivetrain response. Forged from 7075 T6 aluminium and hard coated, this 21-tooth unit keeps mass low while resisting wear under race conditions. It suits hobbyists aiming to refine gearing without adding unnecessary weight.

Accurate Machining for Smooth Operation

Each gear is finished on specialist gear cutting equipment to ensure precise tooth geometry and concentric running. This reduces drivetrain noise and vibration. The internal threads match both standard and lightweight XCA clutchbells for easy installation and dependable alignment.

Clear Tooth Markings and Setup Flexibility

The tooth count is etched on the gear body to speed changes during practice or race day. Available in common sizes, the pinion enables riders to experiment with ratios to suit varying track grip and motor setups.

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 use this pinion with different clutchbell types?

Yes. The thread pattern is compatible with both standard and lightweight XCA clutchbells, making it flexible for swaps.

Is the hard coating repairable if damaged?

Minor surface wear can be managed by careful cleaning, but deep damage to the coating typically requires replacement to maintain tooth accuracy.

What is the best way to check pinion-mesh?

Set the pinion mesh using a strip method or feeler technique, then rotate the drivetrain to ensure even contact without binding. Recheck after a short run.
