Traxxas Spur 68-Tooth Gear 32-Pitch 0.8 Metric RC Car Component TRX3961

Overview

The Traxxas Spur 68-tooth Gear (TRX3961) is an essential tuning component for RC enthusiasts looking to optimise their Traxxas model's performance. Whether you're running an E-Maxx, Revo, or another compatible Traxxas RC car, UK, this precision-engineered spur gear allows you to fine-tune acceleration and top speed to match your specific running conditions. As a critical drivetrain component, the spur gear works in conjunction with your pinion gear to determine your vehicle's overall gear ratio, making it one of the most important performance-tuning parts you can upgrade or replace.

Traxxas spur gears are manufactured to exacting standards, ensuring smooth, reliable operation and consistent performance whether you're racing competitively or bashing casually. The 68-tooth configuration offers a specific gear ratio that balances acceleration with top speed, making it an excellent choice for many Traxxas models. By changing your spur gear ratio, you can adapt your RC car to different terrain types, track layouts, and driving styles, giving you complete control over how your vehicle performs in the field.

This is the kind of upgrade that separates serious RC enthusiasts from casual users. If you're serious about getting the best performance from your Traxxas RC car, understanding gear ratios and having quality replacement gears like this in your spares box is essential. The TRX3961 is an authentic Traxxas part, backed by the company's reputation for quality and reliability.

Key Features

• 68-Tooth Spur Gear Design — This specific tooth count creates a precise gear ratio that affects how your RC car accelerates and reaches its maximum speed, allowing you to optimise performance for your particular model and driving conditions.
• 32-Pitch Specification — The 32-pitch (0.8 metric pitch) standard ensures perfect compatibility with Traxxas pinion gears and drivetrain components, meaning you can confidently install this gear knowing it will mesh smoothly without gaps or binding.
• Performance Tuning Capability — By swapping your existing spur gear for the 68-tooth option, you can significantly alter your vehicle's performance characteristics, adjusting the balance between acceleration and top speed to suit different tracks, terrain types, and your personal driving preferences.
• Genuine Traxxas Manufacturing — This is an authentic Traxxas part, manufactured to the same exacting standards as the components in your original model, ensuring reliability and longevity even during aggressive driving and competitive racing.
• Universal Compatibility — Designed for use with Traxxas models including E-Maxx and Revo platforms, this spur gear is a versatile tuning solution for owners of multiple Traxxas vehicles.
• Essential Replacement Part — Over time, spur gears experience wear from continuous use, and having replacement gears readily available ensures you can keep your RC car running at peak performance without extended downtime.

Technical Performance

The Traxxas Spur 68-tooth Gear operates as a critical component within your RC car's drivetrain system. In combination with your pinion gear, this spur gear determines your vehicle's overall gear ratio, which directly influences acceleration response, top speed capability, and power delivery characteristics. The 32-pitch specification (0.8 metric pitch) is the standard used across Traxxas platforms, ensuring this gear will integrate seamlessly with your existing drivetrain without requiring modifications or adaptations. The 68-tooth configuration positions itself in the mid-range of typical spur gear options, offering a balanced approach to performance tuning that works well for drivers who want a blend of acceleration and top speed rather than extreme specialisation in either direction. Traxxas manufacturing ensures precise tooth geometry and material quality, reducing wear rates and extending the service life of both this gear and your pinion gear. When selecting spur gears for your RC car, always consult your specific model's owner's manual to determine which tooth counts are recommended for your particular vehicle and your intended use. Different spur gear ratios suit different scenarios: lower tooth counts provide quicker acceleration at the cost of lower top speed, whilst higher tooth counts increase top speed but reduce acceleration response. The 68-tooth option represents an excellent middle ground for general-purpose driving, whether you're running your Traxxas RC car on the street, dirt, grass, or track surfaces.

Frequently Asked Questions

• What is a spur gear and why would I need to change it? — The spur gear is a critical drivetrain component that works with your pinion gear to create your RC car's overall gear ratio. By changing your spur gear to a different tooth count, you can adjust how your vehicle accelerates and reaches top speed. Lower tooth counts favour acceleration, whilst higher tooth counts favour top speed. The 68-tooth size offers a balanced middle ground suitable for general driving across various conditions.
• How do I know if the 68-tooth spur gear is compatible with my Traxxas model? — The 68-tooth configuration at 32-pitch (0.8 metric pitch) is compatible with E-Maxx and Revo models, as well as other Traxxas platforms that use 32-pitch gears. However, you should always consult your specific model's owner's manual to confirm which spur gear tooth counts are recommended and compatible with your vehicle.
• Is this suitable for beginners? — Whilst spur gears are typically considered intermediate-level tuning parts, any RC enthusiast interested in performance optimisation can benefit from understanding and experimenting with gear ratios. Beginners should consult their model's manual to determine factory-recommended gear ratios before making changes, ensuring they select appropriate ratios for their experience level and driving style.
• What is the difference between the 68-tooth spur gear and other tooth counts? — Spur gears come in various tooth counts, each creating a different gear ratio. The 68-tooth option provides a balanced ratio; lower tooth counts (such as 60-tooth or 64-tooth) deliver faster acceleration but lower top speed, whilst higher tooth counts (such as 72-tooth or 76-tooth) increase top speed but reduce acceleration. Your choice should depend on your specific Traxxas model, the terrain you're driving on, and your performance priorities.
• How often should I replace my spur gear? — Spur gears are consumable parts that wear over time depending on driving frequency and intensity. High-performance drivers or those who bash regularly may need replacement more frequently than casual users. Always inspect your spur gear periodically for signs of tooth wear, chipping, or stripping, and replace it if you notice damage or performance degradation.
• What tools do I need to install this spur gear? — Installation requirements vary by Traxxas model, but typically you'll need basic RC tools such as a hex wrench set and possibly a gear puller, depending on how your specific vehicle's spur gear is mounted. Consult your model's owner's manual for detailed installation instructions and specifications.
