Frequently Asked Questions

• What is a spur gear and why do I need it? — The spur gear is a critical drivetrain component that meshes with your motor's pinion gear to transfer power from the motor to your RC car's wheels. The tooth count (in this case 87 teeth) directly affects your vehicle's acceleration and top speed. Spur gears are wear items that can eventually require replacement after extended use, particularly if you drive aggressively or compete regularly, making this spare part an essential item for any RC enthusiast.
• Which RC models use this TRX4687 spur gear? — This 87-tooth 48-pitch spur gear with bushing is compatible with various Traxxas RC models that specify 48-pitch drivetrain components. You should verify your specific model's documentation or parts diagram to confirm this is the correct replacement gear, as different Traxxas models may use different tooth counts and pitch specifications.
• What does 48-pitch mean? — Pitch refers to the spacing and size of the gear teeth. 48-pitch is an industry-standard gear pitch that's widely used across numerous RC manufacturers and models. It ensures compatible meshing with standard 48-pitch pinion gears and represents a proven engineering specification that balances strength, efficiency, and smooth operation.
• Will changing my spur gear affect my RC car's performance? — Yes, changing your spur gear's tooth count will alter your vehicle's performance characteristics. More teeth (higher numbers) generally result in better acceleration but lower top speed, whilst fewer teeth provide higher top speed with reduced acceleration. The 87-tooth configuration offers a balanced compromise suitable for diverse driving conditions.
• Is this spur gear suitable for brushless motors? — Yes, this Traxxas spur gear is suitable for use with brushless motor setups running contemporary 3S, 4S, 5S, or 6S LiPo batteries. Brushless motors deliver significantly more power than brushed alternatives, but this genuine Traxxas component is engineered to withstand that power delivery.
• What's the difference between this and aftermarket spur gears? — Genuine Traxxas parts like this spur gear are engineered specifically for Traxxas vehicles and manufactured to factory specifications. Aftermarket alternatives may vary in material quality, tooth profile accuracy, and durability. Using genuine Traxxas components ensures optimal compatibility, performance, and reliability in your RC car.
• How often will I need to replace my spur gear? — Spur gear lifespan depends on driving intensity, motor power, and maintenance practices. Regular casual driving may yield many hours of use before replacement is necessary, whilst competitive racing or high-power brushless setups may require more frequent replacement as wear accumulates.
