Frequently Asked Questions

• What is a spur gear and why do I need to replace it? — The spur gear is a critical drivetrain component that transmits power from your brushless motor to the wheels of your RC car. Over time, through normal operation, the teeth on the spur gear can wear down or become damaged, especially if you engage in intensive bashing or competition driving. When wear occurs, you'll notice reduced power delivery, slipping, or grinding noises from your gearbox. Replacing the spur gear restores full power transmission and keeps your RC vehicle performing at its best.
• How do I know if the 84-tooth spur gear is right for my RC car? — The correct spur gear tooth count depends on your specific Traxxas model and your desired performance characteristics. Your vehicle's manual will specify the appropriate tooth count for your model. If you're looking to adjust performance, higher tooth counts like this 84-tooth option generally provide better acceleration but may reduce top speed, whilst lower tooth counts increase top speed at the expense of acceleration. The 48-pitch specification is fundamental — you must match the pitch of your pinion gear precisely.
• Is this spur gear compatible with all Traxxas RC cars? — The 48-pitch specification is used across numerous Traxxas models, but not all vehicles. You must verify your vehicle's specifications before purchasing. The TRX4684 model number is specific to Traxxas vehicles that utilise this configuration. Always consult your vehicle's manual or contact our experienced team to confirm compatibility with your particular ready to run RC car or custom build.
• What is the 48-pitch system and why does it matter? — Pitch is a standardised measurement system for gears that defines the relationship between tooth count and gear diameter. In the 48-pitch system, there are 48 teeth per inch of gear diameter. This specification is critical because your spur gear must mesh precisely with your pinion gear — if the pitches don't match, you'll experience poor power delivery, excessive wear, and potential drivetrain damage. Always ensure both components operate within the same pitch system.
• Can I use this spur gear as a performance upgrade? — Yes, spur gears are one of the primary tools for performance tuning your RC car. Since Traxxas offers a complete selection of 48-pitch spur gears with different tooth counts, you can adjust your vehicle's characteristics by selecting a different tooth count. This is one of the most affordable and effective ways to optimise your RC car's acceleration, top speed, and overall driving experience to match your preferences and track conditions.
• What's the difference between this and other spur gears? — This is a genuine Traxxas component manufactured to OEM specifications, ensuring absolute compatibility with your Traxxas model and maintaining the engineering standards the brand is recognised for. Compatible aftermarket alternatives may exist, but genuine Traxxas parts guarantee perfect fitment and maintain your vehicle's performance characteristics. The integrated bushing design is specifically engineered for Traxxas drivetrain systems.
