Traxxas 23-Tooth 32-Pitch 3mm Bore RC Pinion Gear - 10840

The Traxxas TRX10840 is a 23-tooth pinion gear with a 32-pitch tooth profile and 3 mm bore, designed as a direct-fit drivetrain component for compatible Traxxas RC models. Pinion gears are a core part of the gear mesh between the motor and spur gear, and selecting the correct tooth count directly affects the gear ratio, motor load, and overall drive performance. This RC pinion gear is machined to Traxxas specifications, making it a reliable stock replacement or alternative ratio option when tuning your drivetrain.
