Traxxas 15-Tooth Pinion Gear 32-Pitch 5mm Bore with Set Screw TRX5651

Overview

The Traxxas 15-Tooth Pinion Gear (32-Pitch) 5 mm Bore TRX5651 is an essential upgrade component for RC enthusiasts across the UK who want to optimise their Traxxas model's performance. Whether you're running a high-speed basher, a competition racer, or anything in between, pinion gears play a crucial role in determining how your RC car accelerates and reaches its top speed. This genuine Traxxas part allows you to fine-tune your vehicle's gearing setup to match different running conditions, track layouts, and driving styles. By simply changing your pinion gear ratio, you can achieve the perfect balance between acceleration and top speed for your specific needs.

If you're serious about getting the most from your Traxxas RC car, UK, understanding gear ratios is fundamental. The 15-tooth pinion combined with different spur gear sizes creates various gear ratios that directly affect performance. For example, a smaller pinion gear (fewer teeth) will give you higher top speeds but slower acceleration, while this 15-tooth option sits in a versatile mid-range that works well for many applications. This particular gear is designed to fit 5 mm motor shafts, making it compatible with a wide range of Traxxas brushless and brushed motors, and it comes complete with a set screw for secure installation.

Whether you're preparing your ready to run RC car for a specific race, adjusting for winter or summer track conditions, or simply experimenting to find your ideal setup, having a selection of pinion gears in your spares box is essential. The Traxxas 15-tooth pinion gear represents excellent value for money and genuine Traxxas quality that you can trust.

Key Features

• 15-Tooth Configuration — This tooth count provides a balanced gearing option that sits in the middle of the performance spectrum, offering a versatile compromise between acceleration and top speed that works well across many different track conditions and driving styles.
• 32-Pitch Specification — The 32-pitch (0.8 metric pitch) designation ensures compatibility with standard Traxxas spur gears and drivetrain components, allowing you to build the exact gear ratio your RC car needs.
• 5 mm Motor Shaft Bore — This bore size accommodates the 5 mm motor shafts found on most Traxxas brushless and brushed motors, making this gear compatible with the vast majority of current Traxxas RC cars, buggies, and trucks.
• Included Set Screw — The gear comes with a set screw that secures the pinion to the motor shaft, preventing slippage during acceleration and ensuring consistent, reliable performance every time you run.
• Genuine Traxxas Quality — As an official Traxxas part, this pinion gear is manufactured to the same exacting standards as the rest of your vehicle, ensuring perfect fitment and longevity.
• Easy Installation — Simply remove your existing pinion gear and replace it with this 15-tooth option using basic tools, allowing you to adjust your gearing in minutes without specialist knowledge.
• Performance Tuning Tool — By swapping pinion gears, you can experiment with different gearing ratios to discover the optimal setup for your specific RC car, track, and driving preferences.

Technical Performance

The Traxxas 15-Tooth Pinion Gear (32-Pitch) 5 mm Bore is engineered with precision to integrate seamlessly into Traxxas drivetrain systems. The 32-pitch standard (equivalent to 0.8 metric pitch) ensures that this pinion will mesh perfectly with compatible Traxxas spur gears, maintaining smooth power delivery and minimising gear noise and wear. The 5 mm bore is machined to exacting tolerances to fit snugly onto Traxxas motor shafts, and the included set screw provides positive engagement that prevents the gear from rotating relative to the motor shaft during hard acceleration or cornering. The 15-tooth count represents a sweet spot for many RC driving scenarios, offering sufficient acceleration for off-road courses while still allowing decent top-end speed on faster tracks. Whether you're running a brushless or brushed motor, the pinion gear's robust construction will handle the demands of competitive racing, casual bashing, or anything in between. The gear material is selected to withstand repeated engagement and disengagement with your spur gear, maintaining performance across countless runs.

Frequently Asked Questions

• Will this 15-tooth pinion gear fit my Traxxas RC car? — This pinion gear is designed to fit any Traxxas model that uses a 5 mm motor shaft and 32-pitch gearing system. Consult your vehicle's owner's manual to confirm your motor shaft size and recommended gearing options. Most modern Traxxas models, including popular ready to run RC cars, RC buggies, and RC trucks, use the 5 mm shaft specification, making this gear compatible with a huge range of vehicles.
• What is the difference between 15-tooth and other pinion gear tooth counts? — Pinion gear tooth count directly affects your vehicle's gear ratio. A 15-tooth pinion is typically a mid-range option: compared to a smaller pinion (e.g., 13-tooth), it will reduce top speed but improve acceleration; compared to a larger pinion (e.g., 17-tooth), it will increase top speed but reduce acceleration. Your final gear ratio depends on both the pinion and spur gear tooth counts combined.
• How do I install this pinion gear? — Installing the pinion gear is straightforward. Remove your motor from the vehicle (or access the motor shaft), slide off the old pinion gear and set screw, slide the new 15-tooth pinion onto the 5 mm shaft, then tighten the set screw firmly to prevent slipping. Always ensure the set screw is tight before running, as a loose pinion will slip and potentially damage both the gear and motor shaft.
• What gear ratios can I achieve with the 15-tooth pinion? — Your final gear ratio depends on both this pinion gear and your spur gear. For example, a 15-tooth pinion with a 50-tooth spur gear gives a 3.33:1 ratio, while a 15-tooth pinion with a 70-tooth spur gear gives a 4.67:1 ratio. Consult your Traxxas manual for recommended combinations and consider the track type, weather conditions, and your driving style when selecting your setup.
• Is this suitable for beginners? — Absolutely. If you already own a Traxxas RC car, UK, and want to experiment with gearing, this pinion gear provides a simple entry point to performance tuning. You don't need specialist mechanical knowledge; basic tools and your owner's manual are sufficient. Many experienced racers start with a 15-tooth or 16-tooth pinion as a baseline before adjusting up or down based on track feedback.
• What's the difference between 32-pitch and other pitch sizes? — Pitch refers to the spacing of gear teeth. This 32-pitch pinion (also listed as 0.8 metric pitch) is designed to mesh with 32-pitch spur gears commonly found on Traxxas models. Using mismatched pitch sizes will result in poor engagement, increased noise, and potential damage. Always ensure your spur gear matches the pinion pitch.
• Can I use this pinion with brushless and brushed motors? — Yes, this pinion gear is compatible with both brushless and brushed Traxxas motors as long as they feature a 5 mm motor shaft. The gear itself is agnostic to motor type; what matters is the shaft size and pitch compatibility.
