Traxxas 17-Tooth 32-Pitch Pinion Gear 5mm Shaft TRX5643

Overview

The Traxxas 17-T Pinion Gear (TRX5643) is an essential replacement and upgrade component for RC enthusiasts running Traxxas vehicles with compatible drivetrain systems. This precision-engineered pinion gear features a 17-tooth configuration with 32-pitch specifications, designed to work seamlessly with 5mm shaft motors. Whether you're maintaining your existing RC car or optimising your setup for improved performance, this genuine Traxxas pinion gear is the professional choice for serious RC hobbyists across the UK.

Pinion gears are critical drivetrain components that directly influence your RC vehicle's acceleration, top speed and overall performance characteristics. The 17-tooth configuration offers a balanced approach to performance tuning, making this gear suitable for a wide range of RC applications including monster trucks and short course racing vehicles. By selecting a Traxxas genuine pinion gear, you ensure compatibility, reliability and the longevity of your motor and transmission system.

This pinion gear is particularly popular with owners of the Traxxas Stampede 4X4 HD VXL 1/10 4WD RTR brushless electric monster truck and other compatible Traxxas platforms. Users have reported excellent results when pairing this 17-tooth pinion with stock spur gears and aftermarket motors like the Hobbywing 4000KV 3660 motor setup, making it an ideal choice for both stock and modified RC cars in the UK market.

Key Features

• 17-Tooth Configuration — The 17-tooth count provides an effective balance between acceleration response and top-speed capability, making this gear versatile for various driving styles and track conditions without sacrificing either extreme of the performance spectrum.
• 32-Pitch Specification — The 32-pitch (32DP) specification ensures this pinion gear maintains precise mesh alignment with compatible spur gears, resulting in smooth power delivery, reduced vibration and extended drivetrain component lifespan.
• 5mm Shaft Compatibility — The gear features a 5mm bore diameter, making it compatible with standard Traxxas motor shafts and a wide range of brushless motors commonly used in 1/10-scale RC cars, ensuring easy installation and reliable engagement.
• Genuine Traxxas Manufacture — Built to Traxxas' exacting engineering standards, this pinion gear uses quality materials and precision machining to withstand the demands of competitive racing, bashful weekend driving and regular recreational use.
• Direct Motor Engagement — As a pinion gear, this component mounts directly to your motor shaft, providing immediate power transfer and the ability to fine-tune your vehicle's performance characteristics through gear ratio selection.
• Proven Compatibility — This pinion gear is officially compatible with the Traxxas Stampede 4X4 HD VXL in all colour variants (green, blue and orange), providing peace of mind that you're selecting the correct component for your specific vehicle.

Technical Performance

The Traxxas 17-T Pinion Gear represents precision engineering at its finest, delivering the reliability and performance that competitive RC enthusiasts and weekend bashers alike expect from genuine Traxxas components. The 32-pitch specification ensures compatibility with standard Traxxas spur gears, providing consistent mesh engagement and smooth power transmission throughout your vehicle's acceleration range. The gear's 17-tooth configuration creates an optimal gear ratio when paired with compatible spur gears, allowing for responsive acceleration while maintaining usable top-speed performance suitable for both on-road and off-road RC applications. The 5mm shaft bore is machined to tight tolerances, ensuring a secure fit on motor shafts without wobble or slippage, critical factors in maintaining efficient power transfer and reducing premature wear on both the pinion and spur gear teeth. The teeth themselves are precision-cut to Traxxas specifications, providing smooth meshing action that reduces noise, vibration and mechanical stress on the entire drivetrain. This pinion gear's durability makes it equally suitable for the demands of high-powered brushless motors like the Hobbywing 4000KV 3660 and stock Traxxas motor configurations, proving its versatility across the spectrum of RC car modifications.

Frequently Asked Questions

• What vehicles is the Traxxas 17-T Pinion Gear compatible with? — This pinion gear is officially compatible with the Traxxas Stampede 4X4 HD VXL 1/10 4WD RTR brushless electric monster truck in green, blue and orange colour variants. It is also suitable for other Traxxas vehicles using 32-pitch gearing systems with 5mm motor shafts, making it a versatile upgrade component for many RC cars in the Traxxas range.
• How does the 17-tooth configuration affect RC car performance? — The 17-tooth count provides a balanced approach to gear ratio tuning. Compared to smaller pinion teeth, a 17-tooth gear reduces top-end speed slightly but improves acceleration response and torque availability, making it ideal for off-road driving, crawling applications and vehicles prioritising control over outright speed. For comparison, larger pinion gears sacrifice acceleration for higher maximum speed, whilst smaller pinions do the opposite.
• Can I use this pinion gear with aftermarket motors? — Yes, this gear works excellently with high-performance brushless motors like the Hobbywing 4000KV 3660 motor, as confirmed by user reviews praising its performance when paired with such upgrades and stock Traxxas spur gears. As long as your motor features a 5mm shaft and your vehicle uses 32-pitch gearing, this pinion will be compatible.
• What is 32-pitch gearing? — 32-pitch (32DP) refers to the tooth profile and spacing standard for this gear. It ensures precise meshing with compatible 32-pitch spur gears, maintaining smooth engagement, reducing backlash and extending component lifespan. This specification is common in 1/10-scale RC cars across the UK and globally.
• How often should I replace my pinion gear? — With proper maintenance and correct mesh alignment, a quality pinion gear like this Traxxas component can last through hundreds of hours of driving. However, regular inspection for tooth wear, especially the leading edge teeth, will indicate when replacement is necessary. Heavy racing use or incorrect spur gear mesh may require more frequent replacement than casual recreational driving.
• Is this suitable for beginners? — This component is best suited to RC enthusiasts with basic mechanical knowledge, as pinion gear installation and spur gear mesh adjustment require some technical understanding. Beginners should familiarise themselves with these maintenance procedures or seek assistance from experienced RC hobbyists or local hobby shops.
