Machined 21T Pinion Built for Precise Gear Changes

The XRAY 348521 XCA Aluminum Pinion Gear is a carefully produced part designed to improve your RC car's drivetrain. Made from durable 7075 T6 aluminum, this 21-tooth pinion keeps weight down while delivering strong wear resistance thanks to its hard coating. It is suitable for racers who want tighter gear control and smoother acceleration on a variety of tracks.

Precision Tooth Form and Quiet Running

Each pinion is produced using advanced gear machining to achieve accurate tooth profiles and true running. This attention to detail reduces vibration and supports efficient power transfer. The internal thread pattern works with standard and lightweight XCA clutchbells for simple, reliable installation.

Marked Sizes and Flexible Gearing Choices

Gears are laser marked with the tooth count for quick identification during setup or maintenance. Offered in popular tooth counts, the pinion lets hobbyists adjust ratios to match track surface and motor characteristics for better lap times.

Yes. The XRAY 348521 is threaded to work with both standard and lightweight XCA clutchbells, providing a secure fit on either type.

How should I maintain the pinion to extend life?

Keep the pinion clean of grit and check mesh regularly. Light oiling of bearings and avoiding heavy impacts will help preserve the hard coat and tooth profile.

Which track conditions benefit from a 21T pinion?

A 21T pinion is a good middle-ground choice for medium-speed tracks where you want a balance of acceleration and top speed. Try neighbouring sizes to fine-tune performance for your motor and surface.
