Race-Oriented 64 Pitch Pinion for Tuned Setups

The 3RACING 3RAC-PG6419 19T pinion is aimed at hobbyists refining drivetrain response for timed runs. Manufactured from 7075 aluminium, it balances low mass with dimensional stability under load.

Hard Coat for Consistent Tooth Form

The hard coat improves surface durability and helps the pinion retain accurate tooth geometry through repeated high-RPM cycles. This supports predictable gear mesh when fine tuning gearing for competitive performance.

Application and Setup Considerations

Intended for 1/10 scale race and practice cars, the 3RACING 3RAC-PG6419 integrates with standard 64 pitch systems. Check shaft fit and set mesh precisely; small adjustments to pinion tooth count will affect acceleration versus top speed tradeoffs.

How should I verify shaft compatibility before fitting?

Measure shaft diameter and spline count, then test slip fit on the shaft. Secure mounting and concentricity are essential for reliable mesh.

What mesh tolerance do experienced tuners use?

Tuners typically set a minimal backlash that prevents binding while keeping engagement tight. Use a feeler method and verify under load to avoid accelerated wear.

Will the hard coating affect fine tuning feedback?

The coating stabilises the running surface which can lead to steadier feedback at the pinion interface; however, overall drivetrain alignment still dominates handling feel.
