Traxxas 12-T 32-P Heavy Duty Machined Hardened Steel 3mm Shaft RC Pinion Gear - 3942X

The Traxxas TRX3942X is a 12-tooth, 32-pitch pinion gear machined from hardened steel and designed to fit 3mm motor shafts across a wide range of Traxxas RC vehicles. As a heavy-duty replacement pinion gear, it's suited to drivers who want a durable, precise-fitting gear that holds up under regular use. The 32-pitch tooth profile is a common standard across many Traxxas models, making this a go-to RC pinion gear for routine drivetrain maintenance or when swapping motor pinions during gear ratio tuning.
