This genuine Traxxas component is a crucial part of the drive system that transmits power from your motor to the wheels. Understanding gear ratios and having the ability to modify them is part of the essential knowledge base for any serious RC enthusiast in the UK or anywhere else. The TRX6842R is manufactured using Traxxas's proven engineering and materials science, ensuring it will deliver consistent performance throughout its service life and maintain the reliability that Traxxas owners have come to expect.

Key Features

• 50-tooth design — This specific tooth count creates a distinct gear ratio that influences how quickly your RC vehicle accelerates and the maximum speed it can achieve, making it suitable for fine-tuning performance in different running scenarios.
• 0.8 metric pitch specification — The metric pitch measurement ensures precise meshing with compatible pinion gears and drivetrain components, maintaining smooth power delivery and reducing wear across your vehicle's transmission.
• 32-pitch compatible — This gear is engineered to work seamlessly with 32-pitch pinion gears, allowing for straightforward gear ratio modifications without requiring additional component purchases or modifications to your RC car.
• Centre differential compatibility — Specifically designed for vehicles equipped with a centre differential system, this gear contributes to superior traction and handling characteristics, particularly in 4WD Traxxas models like the Slash range.
• Precision engineering — Manufactured to exact specifications by Traxxas, this component features tight tolerances and superior material quality that ensure reliable engagement with mating gears and consistent performance over extended use.
• Easy installation — As a direct replacement component, the TRX6842R can be swapped into your existing drivetrain quickly, allowing you to experiment with different gear ratios to optimise your vehicle for specific conditions without downtime.
• Genuine Traxxas component — This is an original Traxxas spare part, ensuring complete compatibility and maintaining your vehicle's warranty and reliability standards.

Technical Performance

The Traxxas Spur 50-tooth gear represents a critical component in your RC vehicle's drivetrain system, directly influencing how power from your brushless motor or brushed motor is distributed to propel your vehicle forward. The 0.8 metric pitch specification denotes the precise distance between teeth, which must match exactly with your pinion gear to ensure smooth, efficient power transmission without slipping, grinding, or premature wear. Changing spur gear ratios is one of the most accessible performance modifications available to RC enthusiasts, offering measurable changes to acceleration and top speed without requiring technical expertise or expensive electrical upgrades. With a 50-tooth count, this gear represents a midpoint in the typical range of available options, making it suitable for drivers seeking balanced performance across various conditions. The gear is engineered from durable materials capable of withstanding the stresses of high-performance RC driving, whether you're running on grass, dirt, or tarmac. For centre differential-equipped vehicles, the spur gear plays a vital role in the overall drivetrain architecture, contributing to traction control and cornering stability. Traxxas gears are manufactured using quality control processes that ensure each component meets strict dimensional tolerances, resulting in consistent mesh patterns and minimal backlash that would otherwise rob your vehicle of efficiency.

Frequently Asked Questions

• What is a spur gear and why would I need to change mine? — The spur gear is the large gear mounted on your RC vehicle's main drivetrain shaft that meshes with a smaller pinion gear driven by the motor. By changing spur gears, you alter your vehicle's gear ratio, which directly affects acceleration and top speed. A larger tooth count (like the 50-tooth) typically provides better acceleration but slightly lower top speed, whilst a smaller tooth count allows higher speeds but requires more powerful acceleration inputs from the driver.
• How do I know if the TRX6842R is compatible with my Traxxas RC model? — This 50-tooth spur gear is compatible with Traxxas models equipped with a centre differential and designed to work with 32-pitch pinion gears. Specific compatible models include various Traxxas Slash variants such as the Slash Ultimate 4x4 VXL and Slash VXL 1/10 4x4 models. You should consult your vehicle's owner's manual or contact RC Model Shop to confirm compatibility with your specific model.
• What is the difference between metric pitch and 32-pitch gears? — Metric pitch and 32-pitch are two different measurement systems for gear specifications. Metric pitch measures in millimetres, whilst 32-pitch is an imperial measurement. The TRX6842R is specified as 0.8 metric pitch and is compatible with 32-pitch systems, meaning Traxxas has engineered this gear to work across their range of vehicles regardless of which measurement system they use.
• Can I mix different spur gear sizes on my vehicle? — No, you should use a matching spur gear appropriate for your entire drivetrain as specified in your vehicle's manual. All spur gears on your RC model should have the same tooth count and pitch specification to ensure balanced performance and prevent damage to your drivetrain.
• What is a centre differential and why does this gear matter for it? — A centre differential is a drivetrain component that allows the front and rear axles of your 4WD vehicle to rotate at different speeds when turning corners, improving traction and handling. The spur gear is a critical part of this system, transmitting power efficiently through the differential to all wheels. Using the correct spur gear ensures your centre differential operates optimally.
• How often should I replace my spur gear? — Spur gears are durable components that typically last through many hours of use. However, if you notice grinding noises, performance changes, or visible wear on the teeth, it's time to replace it. Keeping spare gears like the TRX6842R on hand ensures you can continue running your RC car without interruption.
• Is this suitable for beginners? — This spur gear is appropriate for RC enthusiasts at any skill level. Beginners can use it to experiment with gear ratios and learn how changes affect vehicle performance, whilst advanced drivers use it to optimise their setup for competition or specific conditions.
