Traxxas 31-T 48-Pitch 3mm Shaft RC Pinion Gear - 2431

The Traxxas 2431 is a 31-tooth, 48-pitch pinion gear designed to fit 3mm motor shafts, making it a direct-fit replacement or gearing option for a wide range of Traxxas electric RC models. Supplied with a set screw for secure shaft mounting, TRX2431 is the go-to pinion gear when you need to swap out a worn part or adjust your gear ratio. A 48-pitch pinion is a standard spec across many Traxxas electric vehicles, so this gear slots straight in without modification.

Key Features

• 31-tooth count on a 48-pitch gear profile — a standard Traxxas spec for many electric RC models
• Fits 3mm motor shafts, which are common across Traxxas brushed and brushless motor setups
• Includes a set screw for a firm, rattle-free fit on the motor shaft
• Changing pinion tooth count adjusts the overall drive ratio — a higher tooth count increases top speed, a lower count increases torque and acceleration
