Traxxas 9-Tooth 32-Pitch Pinion Gear with 3mm Bore Set TRX6745

Overview

The Traxxas 9-T Pinion Gear (32-pitch) Set TRX6745 is an essential tuning component for RC enthusiasts across the UK who want to optimise the performance of their Traxxas models. Whether you're a dedicated basher, a weekend racer, or an RC car UK hobbyist looking to fine-tune your setup, this pinion gear allows you to adjust your vehicle's acceleration and top speed characteristics to suit different running conditions and terrain. Traxxas pinion gears are precision-engineered components that give you the power to customise your RC experience without needing an entirely new drivetrain.

This 9-tooth pinion gear is designed to fit 3 mm motor shafts and comes complete with a set screw for secure installation. By changing gear ratios on your Traxxas model, you can strike the perfect balance between acceleration response and maximum velocity, whether you're tackling tight indoor tracks, open outdoor courses, or varied terrain. The ability to swap pinion gears is one of the most cost-effective ways to adapt your brushless RC car UK setup to different driving scenarios and personal preferences.

Compatible with a wide range of Traxxas models including the Rustler Ultimate VXL, TRX-4 Crawler variants, and other Traxxas vehicles, the TRX6745 represents genuine Traxxas engineering and quality that has made the brand a trusted name in RC hobby retail for decades. RC Model Shop stocks this essential upgrade component to help you get the most performance and enjoyment from your Traxxas investment.

Key Features

• 9-Tooth Pinion Configuration — With 9 teeth, this pinion gear provides a specific gear ratio that influences how power from your brushless motor is delivered to the wheels, making it ideal for users who want slightly higher acceleration with a slightly more modest top speed compared to larger pinion options.
• 32-Pitch Design — The 32-pitch specification ensures compatibility with a wide range of Traxxas spur gears and drivetrain components, maintaining the precision tolerances that Traxxas is recognised for in the RC hobby.
• 3 mm Motor Shaft Bore — Engineered to fit 3 mm motor shafts, this pinion gear integrates seamlessly with standard Traxxas brushless motors, ensuring proper alignment and efficient power transfer to your RC vehicle's drivetrain.
• Included Set Screw — The set screw provides a secure mechanical lock on the motor shaft, preventing slippage under acceleration and ensuring consistent performance during aggressive driving or racing conditions.
• Performance Tuning Capability — By swapping pinion gears, you unlock the ability to fine-tune your Traxxas model's performance characteristics, allowing you to optimise for acceleration in tight courses or top speed on open terrain without purchasing a complete new drivetrain.
• Genuine Traxxas Component — As an official Traxxas part, this pinion gear meets the manufacturer's exacting standards for material quality, tolerances, and durability, ensuring reliable performance season after season.

Technical Performance

The Traxxas 9-T Pinion Gear represents precision engineering designed to integrate with Traxxas's comprehensive drivetrain ecosystem. With a 9-tooth count and 32-pitch specification, this pinion gear modulates the relationship between motor speed and wheel speed through gear reduction. The 3 mm bore is machined to tight tolerances to fit standard Traxxas brushless motors securely, whilst the included set screw locks the gear firmly to the motor shaft, preventing rotation during hard acceleration or high-speed running. This component is manufactured from durable materials selected to withstand the stresses of RC driving, whether you're running a Traxxas Rustler Ultimate VXL 4x4 brushless truck, a TRX-4 crawler, or another compatible Traxxas model. The pinion gear's design allows users to experiment with different tooth counts (such as this 9-tooth option) to discover the optimal balance between torque delivery and top speed for their specific driving style and terrain. Many UK RC enthusiasts favour pinion gear swaps as a maintenance item and performance tuning tool, as it's faster and more economical than replacing entire drivetrain assemblies.

Frequently Asked Questions

• What does a 9-tooth pinion gear do on an RC car? — A pinion gear is the small gear that connects directly to your brushless motor and meshes with the larger spur gear in your transmission. The 9-tooth count affects the overall gear ratio, influencing how much power from the motor is converted into wheel speed. Fewer teeth on the pinion (like this 9-tooth design) means higher acceleration but a slightly lower top speed, whilst more teeth provide the opposite effect. Choosing the right pinion tooth count lets you optimise your RC model's performance for your preferred driving style.
• Which Traxxas models are compatible with the TRX6745? — The TRX6745 is compatible with numerous Traxxas vehicles including the Traxxas Rustler Ultimate VXL 4x4 brushless models, TRX-4 Crawler variants such as the Chevrolet K10 Cheyenne, Ford F-150 Ranger XLT, Chevy K5 Blazer, Nissan Pathfinder, 2021 Ford Bronco, and TRX-4 Defender, TRX-4 Sport, and many others. Always consult your specific model's owner's manual to confirm compatibility and recommended gearing options.
• How do I install a pinion gear on my Traxxas RC model? — To install the 9-tooth pinion gear, you'll need to remove the motor and slide the new gear onto the 3 mm motor shaft. Position it so it meshes correctly with the spur gear, then tighten the included set screw securely to lock the gear in place. Your model's owner's manual will provide detailed step-by-step instructions specific to your vehicle.
• What is the difference between this 9-tooth pinion and other tooth counts? — Traxxas offers pinion gears in various tooth counts. This 9-tooth pinion provides a balanced option for general-purpose driving. Smaller tooth counts (like 8-tooth) increase top speed but reduce initial acceleration, whilst larger tooth counts increase acceleration and torque response but lower top speed. Your choice depends on your terrain, track layout, and driving preferences.
• Is this suitable for both indoor and outdoor RC car UK use? — Yes, the pinion gear itself works in both environments. However, the right tooth count choice may differ between indoor carpet tracks and outdoor terrain. Many UK RC enthusiasts keep multiple pinion gears on hand to swap between different running conditions, making this an excellent addition to any serious hobbyist's spare parts collection.
