3RACING 3RAC-PG6433 64 Pitch 33T Hard Coated Pinion Gear (7075) - Racing Grade  [3RAC-PG6433]

Race-focused 64 Pitch Pinion for Tuning Precision

The 3Racing 64 Pitch Pinion Gear 33T is engineered for competitive setups where tooth accuracy and consistent mesh are essential. Fabricated from 7075 aluminum and treated with a hard coating, this pinion maintains profile integrity under high RPM and torque cycles.

Performance Characteristics

64 pitch gear geometry provides tighter engagement and reduced backlash, assisting in predictable drivetrain response during lap runs. The 33T count offers a tuning point that balances acceleration with top end for varied track demands.

Material and Surface Finish

7075 aluminum delivers elevated yield strength while keeping rotational weight low. The hard coating increases surface hardness and resistance to pitting, which is important for repeatable gear ratios and reduced maintenance between events.

Installation and Setup Notes

Intended for 1/10 scale transmissions that accept 64 pitch pinions. Confirm shaft diameter and securement method, then set pinion depth and mesh using standard measurement techniques to avoid premature flank wear and to optimise quiet operation.
