3RACING 3RAC-PG6440 64 Pitch 40T Hard Coated Pinion Gear  [3RAC-PG6440]

Durable 3RACING 3RAC-PG6440 64 Pitch Pinion for RC Builders

The 3RACING 64 Pitch Pinion Gear 40T is built for hobbyists who want to sharpen drivetrain response. Machined from 7075 aluminum and finished with a hard coating, this pinion balances low weight with improved surface hardness to resist wear during frequent running.

Smooth, Predictable Power Transfer

The 64 pitch tooth pattern delivers refined engagement for efficient power transfer and quieter gear mesh. The 40-tooth option gives you useful granularity when adjusting gear ratios for either speed or torque on track day or at the park.

7075 Aluminum Strength with Surface Protection

7075 aluminum offers a high strength-to-weight ratio compared with common alloys, while the hard coating adds a tougher wear layer. This combination helps retain tooth profile integrity under aggressive use.

Straightforward Fitment for 1/10 Scale Setups

Designed to suit many 1/10 scale transmissions, this pinion is a direct upgrade for users seeking improved drivetrain life and easier tuning. Installation is simple with standard pinion-fit methods used across most hobby setups.
