Frequently Asked Questions

• What vehicles is the Traxxas 31-T Pinion Gear compatible with? — This pinion gear is specifically designed for Traxxas models including the UDR Unlimited Desert Racer Pro-Scale 4WD RTR Short Course Truck with both Fox Racing and Rigid Industries packages. Its 0.8 metric pitch with 32-pitch compatibility also makes it suitable for other Traxxas vehicles and compatible aftermarket setups that use standard 5mm motor shafts.
• How do I know if I need to replace my pinion gear? — Pinion gears should be inspected regularly for signs of wear, including chipped or rounded teeth, unusual grinding noises during acceleration, or slipping sensation during power delivery. If you notice any of these signs, replacement with a genuine Traxxas pinion gear is recommended to maintain optimal performance.
• What's the difference between 31-tooth and other tooth counts? — Tooth count directly affects your RC vehicle's speed and torque characteristics.
