Centax 20T Pinion by Serpent

The Serpent 903801 Centax gear-pinion is a quality aluminium 20-tooth unit engineered for the XLI Gen2 clutch system. It provides predictable tooth contact and reliable power transfer for track conditions, making it a practical choice for racers who want a sturdy replacement or upgrade. Regular inspection will keep the pinion performing well over many sessions.

Will the Serpent 903801 fit older XLI variants?

It is optimised for XLI Gen2. Some older clutch types may require adapters or will not match spline profiles, so verify compatibility before fitting.

What maintenance keeps an aluminium pinion in top shape?

Remove grit after each run, check for nicks on the teeth, and replace if deformation appears. Proper mesh setup reduces premature wear.

Should I match the pinion to a specific spur gear pitch?

Yes, ensure the pinion and spur share the same pitch and compatible tooth profile for smooth engagement and even wear.

Are there tuning benefits to using this pinion?

Swapping tooth counts changes acceleration and top speed characteristics. The 20T option is a good baseline for balanced performance on many tracks.

Where can I source spares if I race often?

Check official Serpent dealers and specialist RC parts suppliers for replacement 903801 pinions and compatible spur gears. Keeping a spare on hand minimises downtime.
