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

Upgrade Your Drivetrain with 3RACING 3RAC-PG6440

The 3RACING 64 Pitch Pinion Gear 40T gives hobbyists a compact, hard-coated option to reduce wear in busy drivetrains. Manufactured from 7075 aluminium, it combines stiffness and low mass for improved handling under load.

Refined Engagement for Consistent Runs

A 64 pitch configuration is aimed at providing a tighter tooth contact pattern, resulting in predictable power delivery and reduced noise. The 40-tooth count helps with incremental ratio changes for both sprint and bash setups.

Why 7075 Aluminium Works Here

7075 aluminium is chosen for its favourable strength-to-weight properties. The additional hard coat gives the surface more resistance to abrasion, keeping tooth profiles intact over repeated sessions.

Compatibility Notes and Simple Installation

This pinion suits a range of 1/10 scale gearboxes when the pitch and shaft spec match. It installs using standard pinion fixing techniques and requires only routine mesh adjustment.
