Key Features
- OEM Traxxas Component — This is a genuine manufacturer part number TRX10762, ensuring perfect compatibility and quality assurance that third-party alternatives cannot match, protecting your investment in RC vehicles.
- 12/47 Gear Ratio — The specific ratio creates an optimised balance between acceleration and top speed, tailored to the Mini Maxx platform for enhanced drivability and handling response in various driving conditions.
- Rear Differential Application — Designed exclusively for rear differential use, this pinion gear delivers torque and traction to the rear axle, critical for cornering stability and acceleration control on ready-to-run RC models.
- Mini Maxx Compatibility — Engineered specifically for the Traxxas Mini Maxx 4WD brushless platform, ensuring plug-and-play installation when combined with the required supporting components.
- Precision Manufacturing — Traxxas pinion gears are manufactured to exacting tolerances, ensuring smooth meshing with the crown gear and minimal backlash for responsive handling and efficient power delivery.
- Requires Supporting Components — This pinion gear requires part #10757 paired with either #10758 or #10760, meaning you'll need to verify your existing setup or purchase the complete differential assembly if upgrading from stock parts.

Technical Performance
The Traxxas Pinion Gear Differential TRX10762 represents precision engineering in RC transmission systems. With its 12/47 gear ratio, this component provides a specific reduction that balances the power delivery from brushless motors with practical drivability across various surfaces. The pinion gear itself operates within the differential assembly, working in concert with the crown gear to distribute power to both rear wheels whilst allowing them to rotate at different speeds during cornering — a critical function for 4WD RC vehicles like the Mini Maxx BL-2S range. The manufacturing quality ensures consistent meshing with minimal backlash, reducing drivetrain noise and improving overall transmission efficiency. For UK RC car enthusiasts operating brushless systems, this gear ratio has been proven in real-world conditions to deliver responsive acceleration without sacrificing top-end speed capability. The materials used in this pinion gear are selected for durability under continuous operation, resisting wear and maintaining performance through numerous driving sessions. Whether you're running the orange, blue, green, or black variants of the Mini Maxx BL-2S, this pinion gear will integrate seamlessly into your transmission system, though installation requires compatibility with the specific differential carrier and crown gear specified in the part requirements.

Frequently Asked Questions
- What does the 12/47 gear ratio mean and how will it affect my Mini Maxx performance? — The ratio represents the relationship between the pinion gear (12 teeth) and the crown gear (47 teeth), creating a 3.92:1 reduction. This means for every rotation of the motor, the wheels rotate approximately 3.92 times. This ratio is designed to provide balanced acceleration and top speed for the Mini Maxx BL-2S platform. A lower pinion number (like 12) delivers more torque and acceleration response, making it ideal for tight technical tracks or terrain-heavy courses. If you want faster top speeds, you might consider a higher pinion tooth count, whilst a lower count emphasises acceleration and control.
- Is this suitable for beginners? — This is a component for experienced RC enthusiasts or those comfortable with vehicle maintenance and upgrades. Installing a pinion gear requires understanding your differential system and having the correct supporting components. If you're new to RC cars, we recommend starting with a ready-to-run RC model and consulting with experienced RC hobbyists or shop staff before attempting differential upgrades. However, if your Mini Maxx requires a replacement rear differential pinion gear, this is the genuine Traxxas part you need.
- What models is this compatible with? — The Traxxas Pinion Gear TRX10762 is designed for the Mini Maxx platform, specifically the Mini Maxx BL-2S range available in black (TRX107154-1-BLK), orange (TRX107154-1-ORNG), green (TRX107154-1-GRN), and blue (TRX107154-1-BLUE). Verify your model before purchasing, as this is a model-specific component.
- Why do I need parts #10757, #10758, and #10760 with this pinion gear? — The pinion gear works as part of an assembly. Part #10757 is the differential carrier that houses the gears, whilst #10758 or #10760 is the crown gear that meshes with this pinion gear. You need the carrier to hold everything in place and the crown gear to create the gear reduction. These components must be installed together to form a functioning differential system. If you already have a differential assembly in your vehicle, you may only need this replacement pinion gear if it's damaged or worn.
- Can I use this pinion gear on other Traxxas models? — This pinion gear is specifically engineered for the Mini Maxx platform. Whilst other Traxxas vehicles use differential pinion gears, they may have different tooth counts and specifications optimised for their particular motors and platforms. Using the wrong pinion gear could result in poor performance, excessive wear, or transmission damage. Always verify compatibility with your specific RC model before purchase.
- How often should I replace my differential pinion gear? — Under normal driving conditions, a quality Traxxas pinion gear lasts a considerable time. However, aggressive driving, crashes, or poor maintenance can accelerate wear. If you notice grinding noises from the differential, erratic power delivery, or visible damage to the gear teeth, it's time to replace it. Regular inspection during vehicle maintenance helps catch wear early.
