Description
This is a 12-tooth, 32-pitch pinion gear for the Team Associated Rival MT10 monster truck and Pro4 SC10 short course platform, the small gear mounted on the motor shaft that meshes with the spur gear to set the vehicle's overall gear ratio. Pinion gear tooth count directly affects acceleration, top speed, and motor temperature, making it a key tuning part for matching gearing to motor, battery, and driving style. It is precision cut for accurate meshing with the spur gear, reducing drivetrain noise, wear, and heat buildup compared to a worn or mismatched gear. This pinion fits the Pro4 SC10, Rival MT10, and Rival MT10 Brushed. It functions as both a direct replacement for a worn or stripped factory pinion and a gearing upgrade for racers and bashers adjusting ratio for more punch off the line or a higher top end. Installation is a simple swap on the motor shaft using the existing set screw, with no other drivetrain components needed.
