The Traxxas Gear, 15-T pinion (32-pitch) (fits 3mm shaft)/ set screw TRX3917 is an essential replacement and tuning component for Traxxas RC enthusiasts in the UK. This precision-engineered pinion gear is specifically designed to work with 3mm motor shafts and comes complete with a set screw for secure installation. Whether you're running a Traxxas TRX-4 crawler, a classic trail truck, or any compatible Traxxas model, this pinion gear lets you fine-tune your RC car's performance to suit your driving style and terrain conditions.

Pinion gears are critical components in any RC vehicle's drivetrain, and upgrading or replacing them is one of the most effective ways to optimise your RC car UK experience. By changing your gear ratio, you can achieve the perfect balance between acceleration and top speed for different running conditions—whether you're tackling rocky trails, smooth concrete, or challenging off-road terrain. The 15-tooth design of this pinion gear provides a specific gear ratio that works perfectly with the spur gears found on a wide range of Traxxas models, making it an ideal choice for serious RC hobbyists who want to get the absolute most out of their investment.

This genuine Traxxas replacement part is manufactured to exacting standards and is the authentic choice for anyone looking to maintain or upgrade their brushless RC car or trail crawler. The 32-pitch specification ensures compatibility with the correct spur gears, and the 3mm bore is precision-machined to fit snugly onto standard Traxxas motor shafts. Whether you're a seasoned RC competitor, a weekend basher, or someone just discovering the world of RC for the first time, having the right pinion gear makes all the difference to your vehicle's handling and performance.

Key Features

• 15-Tooth Precision Design — The 15-tooth count provides a specific gear ratio that balances acceleration with top speed, giving you the flexibility to optimise your Traxxas model for the conditions you're running in, whether that's tight trail work or faster open-track driving.
• 32-Pitch Specification — This gear pitch is engineered to work precisely with 32-pitch spur gears found on compatible Traxxas models, ensuring smooth engagement and reliable power transfer without slipping or grinding.
• 3mm Shaft Compatibility — The 3.2mm bore is designed specifically for 3mm motor shafts, which are standard on most Traxxas electric RC cars and crawlers, making this a direct fit for your vehicle's drivetrain.
• Included Set Screw — The set screw secures the pinion gear firmly onto your motor shaft, preventing slippage during hard acceleration or extreme climbing, which is essential for reliable performance in all driving conditions.
• Genuine Traxxas Quality — As an authentic Traxxas replacement part, this pinion gear is manufactured to the same exacting standards as your original Traxxas RC vehicle, guaranteeing durability and consistent performance.
• Performance Tuning Capability — Changing your pinion gear ratio is one of the most effective ways to fine-tune your RC car's performance without major modifications, letting you adapt to different tracks, terrain, and driving styles quickly and affordably.
• Wide Model Compatibility — This pinion gear is a replacement part for a comprehensive range of Traxxas TRX-4 models, including the Sport High Trail Edition, Ford F-150 Ranger XLT, Chevrolet K10 Cheyenne, Chevy Blazer, Nissan Pathfinder SE-V6, and unassembled chassis kits.

Technical Performance

The Traxxas 15-T pinion gear (32-pitch) represents the pinnacle of precision engineering in RC drivetrain components. Manufactured from high-quality materials, this pinion gear is built to withstand the rigorous demands of RC driving, whether you're running your Traxxas model through rocky terrain, muddy trails, or high-speed circuit racing. The 32-pitch specification ensures that this gear meshes perfectly with compatible 32-pitch spur gears, creating a smooth and efficient power transfer from your brushless motor to the wheels. The precise 3.2mm bore accommodates 3mm motor shafts with minimal clearance, ensuring concentricity and reducing wobble during rotation. This attention to detail is what separates genuine Traxxas components from inferior aftermarket alternatives. The inclusion of a quality set screw means you can secure the gear to your motor shaft with confidence, knowing that hard acceleration, extreme climbs, and emergency stops won't cause the gear to slip. For those seeking to optimise their Traxxas RC car UK setup, this pinion gear allows you to adjust your overall gear ratio by selecting different tooth counts, fundamentally changing how your vehicle accelerates and how fast it can reach top speed. A 15-tooth pinion, when paired with the appropriate spur gear, creates a specific gear ratio that many Traxxas users favour for balanced performance across multiple driving conditions.

Frequently Asked Questions

• What is a pinion gear and why do I need to replace it? — A pinion gear is a small toothed wheel on your RC car's motor shaft that drives the larger spur gear in your transmission. Over time, pinion gears can wear down with use, or you might want to replace yours with a different tooth count to change your vehicle's gear ratio and optimise acceleration versus top speed. This 15-tooth pinion is a direct replacement for worn gears on compatible Traxxas models.
• How does changing the pinion gear affect my RC car's performance? — Your pinion gear tooth count directly affects your vehicle's gear ratio. A 15-tooth pinion creates a specific ratio that balances acceleration and top speed for many driving conditions. Choosing a different tooth count can make your Traxxas model faster (with a higher tooth count) or more accelerative (with a lower tooth count), letting you tune your RC car for the terrain and track you're running on.
• Is this pinion gear compatible with my Traxxas model? — This 15-T pinion (32-pitch) with 3mm shaft is compatible with a wide range of Traxxas TRX-4 models including the Sport High Trail Edition, Ford F-150 Ranger XLT High Trail Edition, Chevrolet K10 Cheyenne High Trail Edition, 1979 Chevy Blazer, Nissan Pathfinder SE-V6 3S 4x4, and unassembled TRX-4 chassis kits. Always consult your vehicle's owner's manual to confirm compatibility and recommended gearing options for your specific model.
• What does 32-pitch mean? — Pitch refers to the size and spacing of the teeth on a gear. 32-pitch (32dp) gears have smaller, more closely-spaced teeth than lower-pitch gears. This 32-pitch pinion is engineered to mesh precisely with 32-pitch spur gears used on compatible Traxxas vehicles, ensuring smooth power delivery and efficient driveline engagement.
• How do I install the pinion gear? — The pinion gear slides onto your motor shaft (which is 3mm in diameter) and is secured using the included set screw. Once positioned correctly on the shaft, you tighten the set screw firmly to prevent any slipping during acceleration or heavy load conditions. Consult your Traxxas owner's manual for detailed installation instructions and torque specifications for your specific model.
• Can I use this pinion with gears of different pitch? — No. This 32-pitch pinion must be used with 32-pitch spur gears. Mixing different pitch gears will result in poor mesh, slipping, grinding, and potential damage to your drivetrain. Always ensure your pinion and spur gear have matching pitch specifications.
• Is this a genuine Traxxas part? — Yes, this is an authentic Traxxas replacement part manufactured to the same quality standards as your original vehicle. Genuine Traxxas components guarantee compatibility and durability, ensuring your RC car performs as designed.
• What is included with this pinion gear? — This package includes the 15-tooth pinion gear and a set screw for installation. No additional tools or components are included, though you may need a hex driver or screwdriver to tighten the set screw, depending on the design used on your specific model.
