Traxxas 28-Tooth Pinion Gear Hardened Steel 1.0 Metric Pitch 5mm Shaft TRX6467

Overview

The Traxxas Gear, 28-T pinion (machined, hardened steel) (1.0 metric pitch) (fits 5mm shaft) with set screw is an essential performance tuning component for RC enthusiasts across the UK who demand precision engineering and reliability from their Traxxas models. This 28-tooth pinion gear represents one of the most critical upgrade decisions you'll make when optimising your RC car UK setup, as gear selection directly influences how your model accelerates, reaches top speed and performs across different running conditions. Whether you're a competitive racer fine-tuning your brushless RC car for track dominance or a weekend basher seeking the perfect balance between punch and velocity, this machined steel pinion delivers the durability and consistency required for serious RC hobby enthusiasts.

Traxxas pinion gears have earned their reputation amongst the RC car community for allowing drivers to achieve precise performance tuning without replacing the entire drivetrain. By selecting the correct tooth count, you gain the ability to customise your model's gear ratio, directly controlling the relationship between acceleration and top speed. The 28-tooth configuration strikes a particular balance that suits many driving styles and track conditions, making it a popular choice for those looking to step beyond the factory standard setup. This component is manufactured to Traxxas's exacting standards, ensuring compatibility with genuine Traxxas motors and drivetrains that power ready to run RC vehicles across the country.

The integration of hardened steel construction with precision machining techniques means this pinion gear will withstand thousands of gear mesh cycles without wearing prematurely or stripping teeth—a common failure point on inferior gears. For UK RC car enthusiasts who invest significantly in their models, choosing quality drivetrain components like this 28-T pinion represents smart long-term thinking, protecting your investment and ensuring consistent performance whether you're racing competitively or enjoying casual sessions at your local RC club.

Key Features

• 28-Tooth Configuration — This particular tooth count provides a specific gear ratio that balances acceleration and top speed, allowing you to fine-tune your Traxxas model's performance characteristics to match your preferred driving style and local track conditions.
• Machined Hardened Steel Construction — The pinion is manufactured from hardened steel that has been precision machined, providing exceptional durability and resistance to tooth stripping or premature wear, even under intensive racing conditions or continuous bashing sessions.
• 1.0 Metric Pitch (1.0 Mod) — This standardised metric pitch specification ensures perfect compatibility with genuine Traxxas spur gears and drivetrain components, guaranteeing smooth, reliable power delivery without binding or excessive backlash.
• 5mm Motor Shaft Fitment — The 5mm bore diameter accommodates standard Traxxas brushless and brushed motors with 5mm output shafts, making this pinion suitable for a wide range of current Traxxas RC vehicles including monster trucks, buggies and stadium trucks.
• Included Set Screw — A precision-machined set screw is provided with the pinion gear, enabling secure fastening to your motor shaft and preventing unwanted rotation or slipping during acceleration or cornering.
• Performance Tuning Capability — By changing pinion tooth count, you unlock the ability to optimise your RC car's performance without expensive drivetrain replacements, giving you unlimited tuning flexibility for different tracks, surfaces and racing conditions.

Technical Performance

This 28-tooth pinion gear exemplifies Traxxas's commitment to engineering excellence and precision manufacturing standards that RC enthusiasts have trusted for decades. The hardened steel construction undergoes rigorous heat-treatment processes that increase material hardness and fatigue resistance, creating a gear that maintains its precise tooth geometry even after extended use. The 1.0 metric pitch specification ensures that tooth engagement with your spur gear is perfectly synchronised, minimising vibration, noise and power loss through the drivetrain. At the molecular level, the hardening process strengthens the steel's crystal structure, preventing the micro-fracturing that leads to tooth stripping on softer gears—a critical advantage when running high-KV brushless motors that generate tremendous torque. The 5mm bore diameter is machined to tight tolerances, providing a press-fit relationship with your motor shaft that remains secure through thousands of acceleration cycles. For UK RC car enthusiasts running brushless systems, this precision engineering means you can push motor performance without compromising gear reliability, enabling you to explore higher-voltage batteries (3S, 4S and beyond) whilst maintaining drivetrain integrity. The included set screw provides an additional locking mechanism, ensuring the pinion cannot slip under the extreme acceleration forces generated by modern brushless motors.

Frequently Asked Questions

• What does changing my pinion gear tooth count actually do to my RC car's performance? — Pinion tooth count directly determines your vehicle's gear ratio. Selecting a lower tooth count (such as this 28-tooth option) increases your overall gear ratio, delivering higher top speed but potentially reducing acceleration and hill-climbing torque. Conversely, running fewer teeth accelerates the gear faster but spins the motor harder, increasing current draw and heat. By consulting your Traxxas model's owner's manual, you'll find recommended tooth counts for different driving conditions, allowing you to make informed decisions that match your preferred driving style.
• Is this 28-tooth pinion suitable for both racing and bashing? — Yes, the 28-tooth configuration is versatile enough for both applications. However, your owner's manual will specify the recommended pinion tooth range for your particular Traxxas model. Some models favour lower tooth counts for maximum speed, whilst others are optimised for slightly higher counts that provide better acceleration and torque characteristics. Always consult your specific model documentation to ensure you're within the manufacturer's recommended range.
• What makes the hardened steel construction so important compared to standard steel? — The hardening process dramatically increases the gear's resistance to tooth stripping, wear and deformation. Standard steel gears gradually lose their precise tooth geometry under load, causing increasingly rough gear mesh, vibration and eventual failure. Hardened steel gears maintain their original profile through thousands of operating hours, providing consistent power delivery and reliability. For anyone running high-performance brushless systems, the hardened construction is genuinely essential for durability.
• Will this pinion gear fit my Traxxas model? — This pinion is designed to fit any Traxxas model equipped with a 5mm motor shaft and 1.0 metric pitch drivetrain. However, before purchasing, you should consult your specific model's owner's manual to confirm that a 28-tooth pinion falls within the recommended range for your vehicle. Different Traxxas models have different gear recommendations based on their motor type, final drive ratio and intended performance characteristics.
• How do I install this pinion gear onto my motor? — The pinion slides onto your 5mm motor shaft and is secured using the included set screw. Ensure the set screw is tightened securely but not over-tightened, which could damage the shaft. Your vehicle's owner's manual will provide specific installation torque specifications if required. After installation, verify that the pinion rotates freely and meshes smoothly with your spur gear without binding.
• Can I use this pinion with brushless motors, or is it only for brushed motors? — This 28-tooth pinion is compatible with any genuine Traxxas motor featuring a 5mm output shaft, whether brushless or brushed. The pinion itself is motor-agnostic; the real consideration is ensuring the tooth count falls within your specific model's recommended range, as different motors and vehicles have different optimal gearing specifications.
