Traxxas 16-T 32-P Heavy Duty Machined Hardened Steel 3mm Shaft RC Pinion Gear - 3946X

The Traxxas 3946X is a 16-tooth, 32-pitch pinion gear machined from hardened steel for use with Traxxas RC models running a 3mm motor shaft. As a heavy-duty replacement for the standard pinion gear, TRX3946X is built to handle the demands of repeated high-load use without the wear you'd see from a softer steel component. The gear is secured via a set screw and drops directly onto compatible 3mm shafts, making it a straightforward like-for-like swap when your existing 32-pitch pinion gear shows signs of wear or stripping.

Key Features

• 16-tooth, 32-pitch (32-p) specification suits the standard drivetrain gearing on a wide range of Traxxas models

• Designed for motors with a 3mm output shaft — confirm your motor shaft diameter before ordering
• Secured with a set screw for a firm, rattle-free fit on the motor shaft
