Overview

The Traxxas 20-T Pinion Gear (1.0 metric pitch) Set is a genuine OEM replacement component designed for high-performance RC vehicles. This precision-engineered pinion gear is essential for maintaining optimal drivetrain performance in your Traxxas monster truck, buggy or specialist RC car. Whether you're running a Traxxas X-Maxx, XRT, WideMaxx or Maxx Slash, this 20-tooth pinion gear ensures smooth power delivery and reliable acceleration. As an RC enthusiast in the UK, sourcing genuine Traxxas parts is crucial for maintaining your investment and keeping your RC model performing at its best.

Pinion gears are a critical component of any RC car's drivetrain system. They work in conjunction with the spur gear to transfer power from the motor to the wheels, and the tooth count directly affects your vehicle's speed and acceleration characteristics. A 20-tooth pinion gear offers a balanced setup that suits a wide range of driving styles and terrain conditions. Whether you're a weekend basher exploring local tracks or a serious competitor pushing your RC car to its limits, having quality replacement pinion gears on hand is essential maintenance practice. This genuine Traxxas part guarantees compatibility and performance across multiple models in their extensive brushless RC range.

The TRX6494X pinion gear is manufactured to Traxxas's exacting standards using robust materials that withstand the demanding forces generated by high-power brushless motors. The 1.0 metric pitch specification ensures perfect meshing with your vehicle's spur gear, whilst the 5mm shaft bore fits seamlessly into your existing drivetrain. This is the perfect upgrade or replacement part for anyone maintaining a serious brushless RC monster truck, short course truck or high-performance RC vehicle in the UK.

Key Features

• 20-Tooth Configuration — The 20-tooth design provides a balanced gear ratio that delivers good acceleration without sacrificing top speed, making it ideal for both competitive racing and recreational bashing on UK tracks and terrain.
• 1.0 Metric Pitch — This metric pitch specification ensures perfect engagement with compatible spur gears, eliminating gear slop and delivering smooth, efficient power transfer from motor to wheels.
• 5mm Shaft Bore — The standard 5mm shaft diameter fits all compatible Traxxas models including the X-Maxx, XRT, WideMaxx and Maxx Slash ranges, ensuring straightforward installation without modification.
• Genuine Traxxas Component — As an official OEM part, this pinion gear is manufactured to the same exacting specifications as the original equipment, guaranteeing compatibility, durability and performance consistency.
• Wide Model Compatibility — This pinion gear works across multiple Traxxas brushless vehicle platforms including monster trucks, short course trucks and performance RC cars, making it a valuable addition to your spare parts collection.
• Durable Construction — Built to withstand the extreme forces generated by high-torque brushless motors, this gear maintains its tooth profile and engagement characteristics even under continuous high-performance driving.

Technical Performance

The Traxxas TRX6494X pinion gear represents precision engineering designed specifically for high-power brushless RC vehicles. With 20 teeth and a 1.0 metric pitch specification, this gear delivers reliable power transmission from your brushless motor to the spur gear, which then drives your RC car's wheels. The 5mm shaft bore is the industry standard for Traxxas's most powerful brushless models, ensuring seamless integration into established drivetrains. The metric pitch specification is crucial — it determines how precisely the pinion gear meshes with your vehicle's spur gear. Any mismatch in pitch will result in poor engagement, noise, premature wear and potential drivetrain failure. By choosing genuine Traxxas components like this pinion gear, you eliminate compatibility concerns and ensure your RC car's drivetrain operates at peak efficiency. The 20-tooth configuration on this pinion gear offers an excellent balance between acceleration response and top-end speed capability. This makes it suitable for vehicles ranging from the high-speed Traxxas XRT to the ultra-powerful 8S brushless Traxxas X-Maxx monster truck. Whether you're driving across sand dunes, rocky terrain or prepared track surfaces throughout the UK, this gear maintains consistent performance and reliability. The precision manufacturing ensures minimal backlash and maximum efficiency, translating motor power directly into wheel torque and vehicle motion.

Frequently Asked Questions

• Which Traxxas models are compatible with the TRX6494X pinion gear? — This 20-tooth pinion gear with 5mm shaft bore is compatible with a wide range of Traxxas brushless vehicles including the Maxx Slash 1/8 4WD 6S brushless short course truck (all colour variants), WideMaxx monster truck, X-Maxx belted 4WD brushless monster truck, X-Maxx Ultimate, and XRT VXL-8S and XRT Ultimate models. Always verify your specific model number against the compatibility list before ordering.
• What does the 1.0 metric pitch specification mean? — The metric pitch refers to the distance between gear teeth measured in millimetres. A 1.0 metric pitch pinion gear must mesh with a corresponding 1.0 metric pitch spur gear. Using mismatched pitches will result in poor engagement, noise and potential drivetrain damage. Always ensure both your pinion and spur gears use the same pitch specification.
• Why would I need a replacement pinion gear? — Pinion gears wear over time through normal use, especially in high-performance brushless RC vehicles. Worn teeth become rounded, reducing gear mesh efficiency and increasing noise. Additionally, pinion gears can be damaged by impacts or stripped by excessive motor torque. Keeping spare genuine Traxxas pinion gears on hand ensures you can quickly replace a worn component and get back to driving.
• How does tooth count affect my RC car's performance? — Higher tooth count pinion gears (like 20 teeth) provide more acceleration and torque but slightly lower top speed, whilst lower tooth count gears increase top speed but reduce acceleration. The 20-tooth configuration offers a balanced setup suitable for mixed driving conditions and recreational use across UK terrain.
• Is this part easy to install? — Yes. The pinion gear slides onto the 5mm motor shaft and is secured with a small set screw. Installation requires basic tools and takes just a few minutes. Ensure the gear engages smoothly with your spur gear and that both rotate freely without binding before operating your RC vehicle.
• What is the difference between metric pitch and imperial pitch gears? — Metric pitch (measured in millimetres) and imperial pitch (measured in inches) are incompatible and should never be mixed in the same drivetrain. The TRX6494X uses metric pitch, so ensure your spur gear also specifies 1.0 metric pitch to guarantee proper meshing.
