Overview
The Traxxas 20-T Pinion Gear (32-pitch, 0.8 metric equivalent) is an essential performance tuning component for RC enthusiasts looking to optimise their Traxxas models. This precision-engineered pinion gear fits a 5mm shaft and is designed for seamless compatibility with 32-pitch spur gears, making it an ideal upgrade or replacement part for maintaining peak performance in your RC car UK setup. Whether you're a seasoned competitor or a weekend basher, pinion gear selection is a critical aspect of RC tuning that directly impacts your vehicle's acceleration, top speed and overall handling characteristics.
Traxxas pinion gears are manufactured to exacting standards and allow you to fine-tune the performance of your RC model with precision. By changing gear ratios through pinion gear selection, you can achieve the perfect balance between acceleration and top speed for your specific running conditions, whether you're racing on tarmac, dirt, or mixed terrain. This 20-tooth configuration offers a proven performance profile suitable for a wide range of Traxxas models, particularly brushless electric RC vehicles that demand reliable drivetrain components.
The TRX5646 pinion gear is compatible with several popular Traxxas platforms, including the Stampede 4X4 HD VXL range—one of the most capable 1:10 scale brushless electric monster trucks available for UK RC enthusiasts. If you're building or maintaining a high-performance Traxxas setup, this pinion gear is an essential part of your spares box.
Key Features
- 20-tooth configuration — This tooth count strikes an excellent balance for general-purpose driving, offering responsive acceleration whilst maintaining respectable top-speed capability across varied terrain and running conditions.
- 32-pitch (0.8 metric pitch equivalent) — The 32-pitch specification ensures perfect meshing with compatible Traxxas spur gears, delivering smooth power transfer and minimising drivetrain noise and wear during aggressive driving.
- 5mm shaft bore — The precisely machined 5mm bore mates directly with standard Traxxas motor shafts, guaranteeing a tight, reliable fit that prevents slippage and maintains consistent gear engagement under load.
- High-precision manufacturing — Traxxas pinion gears are engineered to tight tolerances using durable materials, ensuring long service life even under the demands of high-speed brushless electric powertrains and competitive racing.
- Performance tuning flexibility — By swapping pinion gears of different tooth counts, you can adjust your vehicle's gearing ratio to suit different track layouts, weather conditions, and driving styles without replacing your entire drivetrain.
- Wide model compatibility — This pinion gear is confirmed compatible with the Traxxas Stampede 4X4 HD VXL in all colour variants, a brushless electric monster truck platform that demands reliable, precision components.
Technical Performance
The Traxxas 20-T Pinion Gear represents the pinnacle of RC drivetrain engineering. Manufactured from hardened steel or equivalent durable material, this pinion gear is designed to withstand the extreme torque and rotational forces generated by modern brushless electric motors in high-performance 1:10 scale RC vehicles. The 32-pitch specification—equivalent to 0.8 metric pitch—is the industry standard for mid-sized electric RC cars and trucks, ensuring compatibility with a comprehensive range of Traxxas spur gears and drivetrain components. The 5mm shaft bore is machined to precise tolerances, eliminating play whilst allowing smooth installation and removal during maintenance. When paired with appropriate spur gears, this pinion configuration delivers the optimal balance of acceleration and top speed for weekend bashing, competitive racing, and general recreational driving. The tooth count of 20 sits in the sweet spot of the gearing range, making it suitable for diverse running conditions and driving styles. Whether you're pushing a brushless motor to its limits or exploring the capabilities of your Traxxas electric RC car, reliable pinion gears like this one are absolutely essential for maintaining drivetrain integrity and performance consistency.

Frequently Asked Questions
- What does a pinion gear do in an RC car? — The pinion gear is mounted on the motor shaft and meshes with the spur gear to transfer rotational force from the motor to the wheels. By changing the pinion tooth count, you adjust the gear ratio, which alters how quickly the wheels turn relative to motor speed. A smaller pinion (fewer teeth) increases top speed but reduces acceleration, whilst a larger pinion (more teeth) improves acceleration but reduces top speed. The 20-tooth configuration offers a balanced middle ground suitable for most driving styles.
- Is the Traxxas 20-T Pinion Gear compatible with my model? — This pinion gear is specifically confirmed compatible with Traxxas Stampede 4X4 HD VXL in blue, orange, and green colour options. It is also suitable for other Traxxas models that use 32-pitch gears with a 5mm motor shaft, though you should consult your vehicle's owner's manual to confirm compatibility before purchasing. Always verify that your spur gear is also 32-pitch to ensure proper meshing.
- What is the difference between 32-pitch and metric pitch gearing? — The source material indicates this pinion gear is 32-pitch, which is equivalent to 0.8 metric pitch. These are two different measurement systems describing the same tooth spacing. 32-pitch is the standard specification used by Traxxas for mid-sized electric RC cars and trucks. If you currently have metric-pitched gears, you should stick with the same system to avoid compatibility issues.
- Do I need any tools to install this pinion gear? — Installation typically requires basic RC tools, which may include a hex key set, shaft collet tools, or a gear puller depending on your specific vehicle's motor setup. You should consult your Traxxas model's owner's manual for detailed installation instructions and any special tools recommended. Always ensure the pinion gear is properly secured to the motor shaft to prevent slippage during operation.
- How often should I replace my pinion gear? — Pinion gear lifespan depends on driving frequency, intensity, maintenance, and general wear. Regular inspection during routine maintenance will reveal signs of tooth wear, chipping, or damage. If you notice grinding noises, slipping, or visible damage, it's time to replace the pinion gear. For competitive racers and frequent drivers, keeping spare pinion gears of different tooth counts is essential for both performance tuning and emergency replacements.
- What spur gears are compatible with this pinion? — This 32-pitch pinion gear is compatible with any 32-pitch spur gear designed for Traxxas vehicles, including the popular 54-tooth spur gear (part number 3956). The source material confirms Traxxas produces a range of spur gears in 32-pitch specification. Always verify spur gear compatibility before installation, and ensure both pinion and spur are the same pitch for smooth meshing and optimal performance.
