Overview
The Traxxas 10-T Pinion Gear Set TRX7645 is an essential replacement component for RC enthusiasts maintaining their electric powered RC vehicles. Whether you operate a high-performance brushless RC car, RC buggy, or other electric RC model, pinion gears are critical drivetrain components that require regular inspection and replacement due to normal wear and tear from racing, bashing, and competitive use. This genuine Traxxas pinion gear set ensures you maintain optimal performance and reliability from your RC hobby investment across the UK and beyond.
Pinion gears are the smaller gears in your RC car's transmission system that directly engage with the larger spur gear, transferring power from your motor to the wheels. Over time, these precision-engineered components can wear, strip, or become damaged through aggressive driving, crashes, or extended use. Having a quality replacement pinion gear set on hand means you can quickly return to the track or bashing field without extended downtime. The Traxxas TRX7645 offers genuine OEM quality at an affordable price point, making it an essential spare part for any serious RC car UK enthusiast.
This 10-tooth pinion gear is designed with precision engineering to maintain the exact specifications required for reliable power transmission in your Traxxas electric RC model. Whether you are a weekend basher exploring the world of RC for the first time or a seasoned competitor running multiple vehicles, having quality spare pinion gears ensures your RC car remains race-ready. The TRX7645 is manufactured to exacting standards by Traxxas, a globally recognised leader in RC technology, ensuring compatibility and performance you can depend on.
Key Features
- 10-Tooth Configuration — The 10-tooth count provides a specific gear ratio engagement with your vehicle's spur gear, directly affecting acceleration and top speed characteristics of your RC car and determining how power is distributed from your brushless or brushed motor to the wheels.
- 48DP Pitch Rating — The 48-diametral pitch specification ensures this pinion gear meshes precisely with compatible Traxxas spur gears, maintaining smooth power delivery and minimising vibration, noise, and mechanical stress during operation of your electric RC vehicle.

Technical Performance
The Traxxas TRX7645 pinion gear set represents precision engineering designed specifically for electric-powered RC vehicles. With its 10-tooth configuration and 48-diametral pitch specification, this component ensures optimal mesh engagement with compatible Traxxas spur gears, providing smooth, efficient power transmission from your brushless or brushed motor to the drivetrain. The 2.3mm bore diameter is precision-machined to exacting tolerances, ensuring a secure fit on standard motor shafts found across Traxxas electric RC car models. This tight tolerancing prevents shaft slipping during high-load conditions such as aggressive acceleration or cornering, maintaining consistent drivetrain engagement whether you are operating your RC vehicle for casual weekend bashing or competitive racing. The gear ratio created by the 10-tooth pinion working in conjunction with your vehicle's spur gear directly influences acceleration characteristics and top speed potential. Constructed from durable materials suitable for repeated engagement cycles, this pinion gear is engineered to withstand the mechanical stresses inherent in RC car operation. The genuine Traxxas manufacturing process ensures reliability and longevity compared to aftermarket alternatives, providing excellent value for RC hobbyists seeking reliable spare components. Whether you operate your RC car UK-wide at local tracks, bash parks, or private property, having a quality pinion gear set ensures your vehicle maintains peak drivetrain performance throughout extended use periods.

Frequently Asked Questions
- What is a pinion gear and why do I need a replacement for my RC car? — The pinion gear is the small precision gear that engages with your RC car's larger spur gear, transferring power from the motor to the wheels. Over time, through normal use, racing, and bashing, pinion gears wear down, can strip teeth, or become damaged. Having quality replacement pinion gears on hand ensures you can quickly restore your RC vehicle to full performance without extended downtime. The Traxxas TRX7645 provides genuine replacement quality at an affordable price.
- Will the TRX7645 10-tooth pinion gear fit my Traxxas RC car? — The TRX7645 is designed as a genuine Traxxas component with a 2.3mm bore diameter and 48-diametral pitch specification. Compatibility depends on your specific Traxxas vehicle model. We recommend checking your vehicle's manual or contacting our expert RC team at RC Model Shop to confirm fitment with your particular RC car before ordering.
- What is the difference between 10-tooth and 12-tooth pinion gears? — Pinion gear tooth count directly affects your RC car's gear ratio and performance characteristics. A 10-tooth pinion creates a lower gear ratio compared to a 12-tooth option, resulting in quicker acceleration but potentially lower top speed. Conversely, a 12-tooth pinion offers higher top speed but slightly reduced acceleration. Choose based on your driving style and the terrain you use your RC vehicle on.
- How often should I replace my pinion gear? — Pinion gear lifespan depends on usage intensity, driving style, maintenance practices, and the quality of your spur gear. Regular inspection during routine RC car maintenance is recommended. If you notice tooth damage, stripping, or wear patterns during inspection, it is time for replacement. Competitive racers may replace pinion gears more frequently than casual bashers.
- Is the TRX7645 suitable for beginners? — Yes, the Traxxas TRX7645 is suitable for RC enthusiasts of all experience levels. Pinion gear replacement is a straightforward maintenance task that does not require advanced technical knowledge or specialised tools. This makes it an ideal entry-level maintenance job for newcomers to the RC hobby wanting to understand their vehicle's drivetrain components.
