3RACING 3RAC-PG6431 64 Pitch 31T Hard Coated Pinion Gear  [3RAC-PG6431]

Long lasting performance from 3RACING 31T pinion

The 3RACING 64 Pitch 31T Pinion Gear is a sensible upgrade for hobbyists aiming to improve drivetrain efficiency. Machined from 7075 aluminium and finished with a hard coating, this pinion balances light weight with toughness for both club races and weekend running.

Built tough with 7075 aluminium

7075 aluminium provides high strength while keeping mass low, helping reduce rotational inertia. The hard coating improves surface wear resistance so the gear holds up under repeated runs without quick deterioration.

Precision engagement for smooth power transfer

The 31T tooth count and 64 pitch profile deliver accurate mesh with compatible spur gears, resulting in consistent power transfer and minimal lash. This makes it useful for fine tuning gear ratios to suit different track surfaces and motor setups.

Fits a wide range of 1/10 scale models

This 3RACING pinion suits many 1/10 scale rigs that use 64 pitch gearing. Use it as a direct replacement or as part of a gearing change to tweak acceleration and top speed characteristics.
