3Racing 3RAC-PG6443 64 Pitch 43T Hardened 7075 Aluminum Pinion  [3RAC-PG6443]

Track-focused 64 Pitch Pinion for Tuners

The 3Racing 3RAC-PG6443 64 Pitch 43T pinion is a compact upgrade for enthusiasts wanting tighter gear engagement and consistent performance. Manufactured from 7075 aluminum with a hard coating, this pinion balances strength with low weight while the 43-tooth profile helps deliver smooth torque transfer under load. It is a solid option for replacing worn parts or tuning gear ratios on race setups.

Robust Construction for Racing Use

Forged from 7075 aluminum, this pinion combines high tensile strength and a low mass to help reduce rotational inertia. The hard coating improves resistance to surface wear and extends service life, making it a dependable choice for sustained track use and frequent running. When swapping gears, this part gives a noticeable durability upgrade over softer alloys.

Smooth Engagement and Consistent Power Delivery

As a 64 pitch, 43-tooth pinion, the gear is engineered for accurate meshing and predictable power transfer across a range of setups. That consistent engagement helps maintain acceleration feel and top end on the track, and the precise tooth cut supports compatibility with standard 64 pitch spurs used in many 1/10 scale cars.
