Traxxas 20-Tooth 32-Pitch 3mm Bore RC Pinion Gear - 2438

The Traxxas 2438 is a 20-tooth pinion gear with a 32-pitch tooth count and 3 mm bore, designed as a direct replacement or gearing option for compatible Traxxas RC vehicles. Pinion gears are a core part of the drivetrain, sitting on the motor shaft and meshing with the spur gear to transfer power to the wheels. Swapping to a different tooth count lets you adjust the gear ratio, which affects top speed and acceleration characteristics depending on your setup. The TRX2438 part number makes it straightforward to confirm you're ordering the correct gear for your model.

Key Features

• 20-tooth, 32-pitch specification — confirm both pitch and bore match your current drivetrain before fitting

• Changing pinion tooth count alters gear ratio — a higher tooth count raises top speed, a lower count increases torque and acceleration
