Key Features
- Machined from Solid Steel — This spur gear is manufactured from solid steel rather than cheaper stamped materials, ensuring superior strength and longevity even under extreme driving conditions. The solid construction means it resists deformation and maintains precise engagement with the pinion gear for consistent performance.
- Hardened Steel Construction — The hardening process applied to the steel increases the gear's resistance to wear and damage from repeated meshing cycles. This hardening extends the service life of the gear significantly compared to non-hardened alternatives, providing better value for money over time.
- Extra-Wide Tooth Face — The wide-face design provides a larger contact surface area between the spur gear and pinion gear. This increased surface area distributes load more evenly, reducing stress concentration and enabling the gear to handle higher power outputs from brushless motors without stripping or damage.
- 50-Tooth Configuration — The 50-tooth count positions this gear as a mid-range option in Traxxas's gear selection, offering a balanced platform from which you can adjust up or down depending on whether you prioritise acceleration or top speed for your specific racing or bashing style.
- 1.0 Metric Pitch — The 1.0 metric pitch specification ensures this gear will mesh perfectly with compatible Traxxas pinion gears and transmission systems. This standardised pitch is crucial for proper engagement, smooth power delivery, and long-term reliability of your RC drivetrain.
- Performance Tuning Capability — By swapping spur gears, you can fine-tune your Traxxas model's performance characteristics without major modifications. This allows you to adapt your RC car or truck to different track layouts, weather conditions, or driving preferences with minimal downtime.
- Wide Model Compatibility — This gear is designed to work with numerous Traxxas platforms including the Maxx Slash 1/8 4WD 6S brushless short-course trucks, Funco Motorsports Pro Scale 8S sand cars, WideMaxx monster trucks, X-Maxx belted 4WD brushless RTR monster trucks, and XRT VXL-8S models across multiple colour options.
Technical Performance
The Traxxas TRX6443 spur gear represents precision engineering at its finest, combining solid steel construction with hardening processes that create a component capable of handling the demanding requirements of modern brushless RC models. At 50 teeth with a 1.0 metric pitch, this gear sits in the sweet spot of Traxxas's gearing range, providing a balanced foundation for performance tuning. The extra-wide tooth face is not merely aesthetic — it's a functional design feature that significantly increases the load-bearing capacity of the gear mesh. When you're running high-torque brushless motors like those found in the 6S and 8S Traxxas platforms, the wider tooth engagement ensures that power is transferred smoothly and efficiently to the wheels without the risk of stripping or premature wear. The machined-from-solid-steel construction means tolerances are tightly controlled throughout the manufacturing process, ensuring that each gear maintains consistent dimensions and engagement characteristics. This precision is essential for smooth operation and for achieving the performance gains you're seeking when tuning your RC vehicle's acceleration and top-speed balance. Whether you're competing in organised RC racing events across the UK or enjoying weekend bashing sessions, the durability and reliability of this Traxxas component means you can focus on driving rather than worrying about drivetrain failures. The hardened steel also resists the cumulative wear that plastic or lower-grade steel gears experience, meaning your investment in this quality component will pay dividends over hundreds of running hours.

Frequently Asked Questions
- What does a spur gear do in an RC car? — The spur gear is a critical component in your RC vehicle's transmission system. It meshes with the pinion gear (which is attached to the motor shaft) to transfer rotational power from the motor to the wheels. The number of teeth on the spur gear determines the overall gear ratio of your vehicle. A higher tooth count (like this 50-tooth) provides more torque and acceleration but lower top speed, while a lower tooth count provides higher top speed but less acceleration.
- How do I know which spur gear size to use? — The ideal spur gear size depends on your driving style, the track or terrain you're using, and your motor's power characteristics. For tighter courses or situations where you need rapid acceleration, a higher tooth count (50-tooth or above) is beneficial. For open areas where you want maximum top speed, a lower tooth count works better. Always consult your Traxxas model's owner's manual for the manufacturer's recommended gearing options for your specific vehicle and driving conditions.
- Is this gear suitable for brushless motors? — Absolutely. This 50-tooth spur gear is specifically designed for use with modern high-power brushless RC motors. The extra-wide tooth face and hardened steel construction ensure it can handle the significantly higher torque output of brushless systems compared to brushed motors. It's used in Traxxas's most powerful models including 6S and 8S brushless platforms.
- What is the difference between this and other spur gears? — This Traxxas spur gear is machined from solid steel with hardening treatment, whereas cheaper alternatives may be stamped from thin steel or made from plastic. The machined-from-solid construction provides superior precision, the hardening treatment extends the gear's lifespan significantly, and the wide-face design handles higher power outputs. Additionally, being a genuine Traxxas part ensures it meets exact specifications for perfect fitment in your model.
- Will this improve my RC truck's performance? — This gear alone won't directly improve performance, but it allows you to tune your vehicle's performance characteristics. If your current gearing doesn't suit your driving conditions, switching to this 50-tooth option (compared to higher or lower tooth counts) can optimise the balance between acceleration and top speed. The quality of this genuine Traxxas component also ensures consistent, reliable performance compared to cheaper alternatives.
- How often should I replace my spur gear? — Spur gear lifespan depends on driving intensity, maintenance, and running surface. The hardened steel construction of this Traxxas gear means it will last significantly longer than non-hardened alternatives. Regular inspection for wear, proper lubrication of the gear mesh, and ensuring your pinion gear isn't worn will all extend spur gear life. If you notice grinding noises, visible wear, or tooth damage, replacement is recommended.
