Race-Oriented 49T Pinion for Precise Setup Work

The 3Racing 64 Pitch 49T pinion 3RAC-PG6449 is manufactured from 7075 aluminium and supplied with a hard coating to stabilize tooth engagement and reduce surface degradation. This pinion is intended for racers and tuners who demand repeatable gear behaviour across heats.

Durable Design for Competitive Use

Material selection and the protective finish combine to maintain tooth geometry under prolonged stress, helping keep backlash predictable and reducing the need for frequent replacements in race scenarios.

Optimised for Incremental Ratio Changes

At 49 teeth, the pinion provides precise ratio steps for tuning acceleration versus top speed. It integrates into standard 64 pitch systems and supports detailed setup changes for different track conditions and motor configurations.

Is the 3RAC-PG6449 suitable for closed class racing?

Yes. The 3RAC-PG6449 is suitable for race classes that use 64 pitch gearing, offering consistent mesh behaviour required in competitive runs.

What installation checks should a tuner perform?

Verify concentricity on the motor shaft, set correct mesh using a gauge or shims, and torque the retaining screw to the motor manufacturers guidance to maintain alignment and prevent slippage.

How does the coating help under race conditions?

The hard coating reduces progressive wear and helps preserve tooth form, which keeps backlash stable over multiple runs and assists with predictable gearing during tuning sessions.
