The 3RACING 3RAC-PG6451 64 Pitch Pinion Gear 51T is precision produced from 7075 aluminium and finished with a hard coating to preserve tooth geometry during repeated high load cycles. Its accurate profile aids in maintaining repeatable mesh for setup tuning.
The hard coat improves surface resistance to pitting while keeping the aluminium core light, allowing racers to balance durability and rotating mass when selecting pinion sizes for different circuits.
Engineers and tuners will find this 51T pinion suitable for standard 1/10 scale on-road and off-road drivetrains where 64 pitch components are specified; confirm spline compatibility and check mesh under load in final setup checks.
