Traxxas 21-T 1.0 Metric Pitch 5mm Shaft RC Pinion Gear - 6493X

The Traxxas TRX6493X is a 21-tooth pinion gear with a 1.0 metric pitch and 5mm shaft bore, designed as a direct-fit drivetrain component for compatible Traxxas RC models. Pinion gears are a core part of the drivetrain, meshing with the spur gear to transfer power from the motor to the rest of the drivetrain, and selecting the correct tooth count and pitch for your build is essential for reliable performance. This RC pinion gear is a Traxxas OEM specification part, making it a straightforward replacement when your existing pinion shows wear.

Key Features

• 21-tooth count with 1.0 metric pitch — confirm your existing gear pitch before ordering, as mixing pitches will cause drivetrain damage
• 5mm shaft bore fits standard 5mm motor shafts used across a range of Traxxas models
• OEM Traxxas specification ensures correct mesh geometry with compatible Traxxas spur gears
• Higher tooth counts like 21T give a higher top-speed bias compared to lower-tooth pinions, at the cost of some low-end torque
