Traxxas Spur 56-Tooth 0.8 Metric Pitch RC Gear - 3957

The Traxxas 3957 is a 56-tooth spur gear designed as a direct-fit spare part for compatible Traxxas RC models. Rated at 0.8 metric pitch and noted as compatible with 32-pitch gearing, TRX3957 is a drivetrain component used to transfer power from the motor pinion to the rest of the driveline. Replacing a worn or stripped spur gear is one of the most common drivetrain repairs in RC cars, and fitting an OEM Traxxas part ensures the mesh and tolerances stay within spec.
