Traxxas Pinion Gear 31-Tooth 48-Pitch Set Screw RC Car Component TRX2431

Overview

The Traxxas 31-T Pinion Gear (48-pitch) Set TRX2431 is an essential performance tuning component for RC enthusiasts across the UK who demand precision engineering and reliable gear systems. Whether you're running a Traxxas Ford Fiesta ST Rally BL-2S or a 1/16 Slash VXL, this 31-tooth pinion gear offers the perfect balance of acceleration and top speed control. As a dedicated RC car UK retailer, we recognise that choosing the right pinion gear is crucial for optimising your brushless RC vehicle's performance on the track or in competitive settings.

Manufactured by Traxxas, a globally recognised leader in RC technology, this pinion gear is engineered to exacting standards using quality materials that withstand the demands of both casual bashers and serious racers. The 48-pitch specification ensures compatibility with a wide range of Traxxas vehicles, making it an ideal upgrade or replacement component for anyone looking to fine-tune their RC car's gearing ratios. With a 3.2mm bore and set screw design, installation is straightforward, and you can expect consistent performance across multiple sessions.

Ready to run RC cars and performance-tuned builds both benefit from having quality spare gears on hand, and this Traxxas pinion gear delivers exactly that. If you're new to RC performance tuning or a seasoned competitor, understanding gear ratios and having the right components is fundamental to getting the most from your investment.

Key Features

• 48-Pitch Specification — This gear pitch is the industry standard for many Traxxas RC vehicles, ensuring broad compatibility across multiple models and allowing you to swap gears quickly to adjust performance characteristics without needing to source obscure alternatives.
• 31-Tooth Count (31-32T) — The tooth count directly influences your vehicle's acceleration and top speed; a 31-tooth pinion gear strikes an excellent balance, offering sufficient acceleration for track work whilst maintaining respectable top speed capabilities depending on your motor and battery setup.
• Traxxas Quality Manufacturing — Every Traxxas component is manufactured to precise tolerances, ensuring smooth engagement with your spur gear, reducing friction losses, and extending the lifespan of your entire drivetrain compared to aftermarket alternatives.
• 3.2mm Bore Diameter — The precisely machined 3.2mm bore accommodates standard Traxxas motor shafts, guaranteeing a secure fit without play or slippage during aggressive driving or high-speed runs.
• Set Screw Design — The included set screw provides a positive locking mechanism that prevents the gear from slipping on your motor shaft, even under extreme acceleration or during hard cornering on challenging RC tracks and terrains.
• Spare Gear Inclusion — This product comes as a set, giving you an additional pinion gear so you have a backup ready whilst one is installed, or allowing you to experiment with dual setups for testing different gearing configurations.
• Performance Tuning Essential — Traxxas offers a wide selection of 48-pitch pinion gears specifically for performance tuning, and this 31-tooth variant is one of the most popular choices for drivers seeking balanced on-track performance.

Technical Performance

The Traxxas 31-T Pinion Gear represents precision engineering at its finest. Manufactured from durable materials that have been tested across countless racing events and casual RC sessions throughout the UK and beyond, this gear is engineered to provide reliable performance lap after lap. The 48-pitch specification is the gold standard for compatibility with Traxxas' extensive vehicle lineup, and the 31-tooth count has been proven through real-world use by racing teams and hobbyists alike. When paired with the appropriate spur gear, this pinion directly influences your vehicle's acceleration curve and maximum velocity; a lower tooth count generally favours acceleration whilst higher tooth counts push towards top speed, making the 31-tooth a sensible middle ground for most driving styles. The 3.2mm bore is machined to tolerances that ensure perfect concentricity, meaning no wobble or runout that could cause premature wear or vibration. The set screw locking mechanism is simple but highly effective, preventing any possibility of gear slip during intense acceleration events that occur in brushless RC cars where motor power delivery is instantaneous. Whether you're running this on a brushless RC vehicle competing in time trials or enjoying weekend bashing sessions, you can rely on Traxxas' quality to deliver consistent, measurable performance every single time you hit the track.

Frequently Asked Questions

• Is the Traxxas 31-T Pinion Gear suitable for beginners? — Yes, absolutely. Whilst performance tuning through gear selection is an advanced concept, simply installing this gear is straightforward even for newcomers to the hobby. If you own a compatible Traxxas RC car UK model, you can confidently install this pinion gear using basic tools. However, understanding gearing ratios and their impact on performance is more relevant to experienced drivers who are actively tuning their setups.
• What Traxxas vehicles are compatible with the TRX2431 pinion gear? — This 31-tooth 48-pitch pinion gear is confirmed compatible with the Traxxas Ford Fiesta ST Rally BL-2S Rally Car (Red) and the Traxxas Ford Fiesta ST Rally VXL (Green). It has also been successfully used on the 1/16 Slash VXL by RC enthusiasts, though you should verify compatibility with your specific model before purchasing. Check your vehicle's documentation or contact our expert team for confirmation.
• How does the 31-tooth count compare to other pinion gear options? — Traxxas offers a wide selection of 48-pitch pinion gears in various tooth counts. Generally speaking, a 31-tooth pinion is considered a mid-range option; lower tooth counts like 25-29T favour acceleration and climbing ability, whilst higher counts like 32-35T push the vehicle towards maximum top speed. The 31-tooth is perfect for drivers who want balanced performance across all driving conditions and don't want to sacrifice too much in either acceleration or speed.
• What is included in this set? — This product is sold as a set, meaning you receive multiple pinion gears plus the necessary set screw for installation. Having a spare gear is invaluable because you can rotate them during maintenance, test different setups, or simply have a backup ready if one becomes damaged.
• How often should I replace my pinion gear? — Quality Traxxas gears like this 31-tooth variant are built to last hundreds of charging cycles with proper maintenance. Inspect your pinion gear regularly for signs of wear, such as chipped or stripped teeth. If you notice damage, replace it immediately to prevent further drivetrain damage. With careful use and routine cleaning, this gear should provide months of reliable service.
• Can I use this pinion gear on other RC cars besides Traxxas? — The 3.2mm bore and 48-pitch specification are standard dimensions, so theoretically this gear could fit other vehicles with the same shaft size and gear pitch. However, Traxxas components are engineered specifically for Traxxas vehicles, and we recommend sticking with manufacturer-matched gearing for optimal performance and reliability.
