Race oriented 64 pitch pinion from 3Racing

The 3Racing 64 Pitch Pinion Gear 41T is produced to support competitive tuning and frequent gear swaps. Constructed from 7075 aluminium with a hard coating, it balances low rotating mass with surface hardness to withstand repeated engagement cycles and high rpm loads.

Material and finish for performance

7075 aluminium provides the tensile strength needed for aggressive launch and braking forces while the hard coating improves wear resistance on the tooth face, helping maintain consistent backlash and mesh characteristics during race events.

Tuning and compatibility notes

This pinion suits 64 pitch drivetrains and is recommended for racers who regularly adjust gear ratios. Confirm motor shaft diameter and mount spacing before installation and perform a mesh check under load to ensure predictable power delivery.

What is the recommended installation check for race use?

Set precise mesh with feeler or shim adjustments, run brief full rpm tests between heats, and inspect teeth for early signs of polishing or micro pitting.

How does tooth count affect gearing strategy?

A 41T pinion will favour higher top speed relative to smaller pinions; adjust the spur accordingly to find the best compromise for torque and lap times.

Any maintenance tips after competitive rounds?

Clean teeth of grit, verify hard coating integrity, and replace the pinion if wear changes mesh or causes vibration during high revs.
