3Racing 3RAC-PG6438 64 Pitch 38T Pinion Gear - Hard Coated 7075 Aluminum  [3RAC-PG6438]

Precision pinion for serious RC tuners

The 3Racing 64 Pitch Pinion Gear 38T, model 3RAC-PG6438, gives hobbyists a reliable way to refine drivetrain response. Machined from 7075 aluminum and finished with a hard coating, this pinion is built to keep gear mesh stable and resist surface wear during frequent running.

Durable construction for extended use

Using 7075 aluminum reduces weight while retaining strength, so the 3Racing pinion holds up under repeated starts and stops. The hard coating adds abrasion resistance to preserve tooth profiles and maintain consistent engagement over time.

Small steps for precise gearing changes

The 64 pitch format lets you make finer ratio adjustments to smooth power delivery and sharpen acceleration. Whether swapping to optimise acceleration or top speed, this pinion helps you dial in the drivetrain with confidence.
