Traxxas Spur Gear Steel 50-Tooth Centre Differential 0.8 Metric Pitch TRX6842X

Overview

The Traxxas Spur Gear, Steel, 50-Tooth (0.8 Metric Pitch, Compatible with 32-Pitch) (for centre Differential) TRX6842X is an essential performance tuning component for serious RC enthusiasts across the UK. Whether you're running a Traxxas Rustler Ultimate VXL or another compatible model, this precision-engineered steel spur gear allows you to fine-tune your RC car's performance characteristics to match your specific driving conditions and preferences. Spur gears are fundamental to controlling the balance between acceleration and top speed in any RC vehicle, making this replacement gear an invaluable part of any RC modeller's tuning toolkit.

As an authorised Traxxas dealer, RC Model Shop stocks genuine OEM replacement parts that meet the exacting standards Traxxas is renowned for. This 50-tooth spur gear is manufactured from high-quality steel, ensuring durability and longevity even under demanding racing conditions. Whether you're a weekend basher enjoying your RC car UK hobby or a competitive racer seeking that competitive edge, understanding and optimising your gear ratios is crucial to unlocking your RC model's full potential.

The beauty of using quality aftermarket gears like the TRX6842X is that you can experiment with different tooth counts to discover the optimal setup for your specific track conditions, terrain type, and driving style. Many UK RC enthusiasts keep multiple spur gears on hand to quickly swap between configurations—this flexibility is what separates good RC car setups from truly outstanding ones.

Key Features

• 50-Tooth Configuration — This tooth count is specifically engineered to work with 32-pitch systems, providing a precise gear ratio that affects how your RC model accelerates and reaches its maximum velocity, allowing you to tune performance for indoor tracks, outdoor racing, or casual bashing.
• Steel Construction — The use of hardened steel rather than plastic or softer materials means this spur gear offers superior durability, resists stripping under load, and maintains its precise tooth profile even after extended use, making it an investment that will last through many seasons of RC car enjoyment.
• 0.8 Metric Pitch Compatibility — The metric pitch specification ensures this gear meshes perfectly with compatible pinion gears and other drivetrain components, maintaining optimal engagement and minimising wear on both the spur and pinion, which translates to smoother, more efficient power delivery.
• Centre Differential Application — Specifically designed for use in the centre differential of compatible Traxxas models, this gear plays a critical role in managing power distribution between the front and rear axles, directly influencing handling characteristics and traction on different terrain types.
• Genuine Traxxas Component — As an official Traxxas OEM part, this spur gear meets strict quality control standards and is guaranteed to fit and function correctly with your compatible RC model, eliminating compatibility concerns and warranty issues.
• Performance Tuning Flexibility — By selecting the 50-tooth option, you're choosing a specific gear ratio that represents a balanced approach to acceleration and top speed; having multiple tooth-count options available means you can experiment and find your perfect setup.

Technical Performance

The Traxxas Spur Gear TRX6842X represents precision engineering at its finest. Manufactured from hardened steel, this component is engineered to withstand the stresses of high-speed RC driving whilst maintaining the exact tooth profile necessary for smooth, efficient power transfer through your model's drivetrain. The 50-tooth design working with 32-pitch specifications creates a specific gear reduction ratio that fundamentally influences how your RC vehicle behaves under acceleration and at top speed. In practical terms, different spur gear tooth counts allow RC enthusiasts to optimise their vehicles for different scenarios—higher tooth counts generally favour acceleration and torque, whilst lower tooth counts permit higher maximum speeds but may reduce initial acceleration. The steel construction is particularly important because it resists the wear and tooth stripping that can occur with plastic gears, especially in high-torque applications or when running powerful brushless motors. The centre differential application means this gear plays a crucial role in the mechanical system that distributes power between your model's front and rear axles, directly affecting how the vehicle handles cornering, traction transitions, and overall stability. For anyone running a compatible Traxxas model—including the Rustler Ultimate VXL 4x4 1/10 Brushless in either green or blue—this is a genuine replacement component that guarantees correct fit and function. UK RC enthusiasts appreciate genuine parts because they eliminate the guesswork and potential compatibility issues that can arise with aftermarket alternatives.

Frequently Asked Questions

• What is a spur gear and why would I need to replace it? — A spur gear is a fundamental component in your RC car's drivetrain that transfers power from the motor to the wheels. Over time, spur gears can wear, strip teeth, or become damaged through normal use. Additionally, different tooth-count spur gears allow you to change your vehicle's gear ratio, tuning performance for different track conditions, speeds, and driving styles. Keeping a spare spur gear on hand is essential for any serious RC enthusiast.
• What is the difference between tooth counts in spur gears? — The tooth count directly affects your RC model's acceleration and top speed characteristics. The 50-tooth option on this Traxxas gear represents a mid-range ratio; higher tooth counts (like 52 or 54) favour acceleration and torque, whilst lower tooth counts (like 46 or 48) allow for higher top speeds. Experimenting with different tooth counts is a key part of performance tuning for your specific driving conditions.
• Is the TRX6842X compatible with my Traxxas model? — This spur gear is confirmed compatible with the Traxxas Rustler Ultimate VXL 4x4 1/10 Brushless model in both green and blue versions. However, it may be compatible with other Traxxas models that use 32-pitch spur gears in the centre differential. Always consult your vehicle's owner's manual for the recommended gearing options and specifications for your specific model.
• Why is steel better than plastic for spur gears? — Steel spur gears offer several advantages over plastic: they resist tooth stripping under high torque loads, maintain their precise tooth profile longer through extended use, and ultimately provide better durability and longevity. If you run a powerful brushless motor or bash aggressively, a steel spur gear is the smart choice for reliability.
• How do I install this spur gear? — Installation procedures vary by model. You'll typically need to access your vehicle's centre differential, remove the old spur gear, and install the new one. Always consult your Traxxas owner's manual for detailed installation instructions specific to your model, as improper installation could affect performance or cause damage.
• Will changing my spur gear void my warranty? — As a genuine Traxxas OEM component, using this spur gear as a direct replacement should not void your warranty. However, always check your vehicle's warranty documentation and contact Traxxas directly if you have concerns about warranty coverage.
