Technical Performance

The Traxxas Spur Gear 78-tooth 48-pitch with bushing represents precision engineering at its finest, offering RC car enthusiasts a reliable drivetrain component that directly impacts vehicle performance. The 48-pitch standard is a widely recognised specification in the RC hobby community, ensuring broad compatibility across multiple Traxxas models and other 48-pitch compatible vehicles. The 78-tooth configuration strikes an excellent balance in the gearing spectrum—larger tooth counts generally favour acceleration and torque delivery, whilst smaller counts emphasise top speed. With 78 teeth, this spur gear is well-suited for drivers who want moderate acceleration without sacrificing significant top-end speed, making it an excellent all-round choice for mixed driving conditions, track work, and general performance driving. The integrated bushing design is a critical engineering feature that cannot be overlooked; it acts as a friction reducer and wear barrier between the gear and the transmission shaft, which means smoother power delivery, reduced noise during operation, and extended intervals between maintenance and component replacement. Traxxas's reputation for quality manufacturing ensures that this spur gear will perform reliably across countless driving sessions, whether you're running on carpet, asphalt, or outdoor terrain. The precision of the gear teeth profile ensures efficient power transfer from the motor through the drivetrain to the wheels, minimising energy loss and maximising the responsiveness of your RC car's acceleration characteristics.

Frequently Asked Questions

• What is a spur gear and why does it matter in RC cars? — A spur gear is a critical drivetrain component that transfers power from your RC car's motor to the transmission and ultimately to the wheels. The tooth count directly affects your vehicle's gearing ratio, which determines how quickly your car accelerates and how fast it can go. The 78-tooth configuration on this gear provides a balanced setup that works well for general performance driving without heavily favouring either acceleration or top speed.
• Will this spur gear fit my RC car? — This Traxxas spur gear is designed for vehicles that use the 48-pitch drivetrain standard. If your RC car is a Traxxas model or another brand that uses 48-pitch gearing, this spur gear should fit perfectly. We recommend checking your vehicle's manual or specifications to confirm compatibility before purchasing. If you're unsure, contact our expert team at RC Model Shop for guidance.
• How often will I need to replace the spur gear? — With proper maintenance and use, quality spur gears like this Traxxas component can last for many driving sessions. The integrated bushing helps reduce wear, extending the gear's lifespan. Replacement frequency depends on factors such as driving style, surface conditions, maintenance practices, and how often you use your RC car. Signs of wear include tooth damage, grinding noises, or reduced acceleration smoothness.
• What is the difference between the 78-tooth and other tooth counts available? — Traxxas offers a complete selection of 48-pitch spur gears with different tooth counts for performance tuning purposes. Lower tooth counts (such as 70) provide faster top speed but reduced acceleration, whilst higher tooth counts (such as 86) favour stronger acceleration but lower top speed. The 78-tooth configuration balances both characteristics, making it ideal for drivers who want versatility across different driving conditions.
• Is this suitable for both beginners and experienced drivers? — Yes, the 78-tooth spur gear is suitable for both recreational drivers and experienced hobbyists. Beginners will appreciate the balanced performance characteristics and reliable operation, whilst experienced drivers can use this component as a baseline for performance tuning, then experiment with other gear ratios to fine-tune their specific setup.
• Do I need any special tools to install this spur gear? — Installation typically requires basic RC car maintenance tools such as a hex wrench or screwdriver set, depending on how your vehicle's transmission is configured. Detailed installation instructions should be available in your RC car's manual or from Traxxas's online resources. If you're unsure about the installation process, our expert team at RC Model Shop is happy to advise.
