The Traxxas 10756X 47‑tooth spur gear is a steel spur gear with a 0.8 metric (32‑pitch) tooth profile designed specifically for the Traxxas Mini Maxx monster truck drivetrain. It mounts directly on the center driveshaft, replacing the stock plastic gear with a more durable steel version that better handles power and torque, especially under aggressive driving or higher voltage setups. Changing this gear affects the overall gear ratio, giving you the ability to fine‑tune acceleration and top speed to suit different tracks or driving styles.
