Traxxas 12-T Pinion Gear 48-Pitch RC Car Drivetrain Component TRX2428

Overview

The Traxxas 12-T Pinion Gear (48-pitch) Set TRX2428 is an essential performance tuning component for RC enthusiasts in the UK who demand precision engineering and reliable drivetrain components. Whether you're running a high-performance rally car, competitive racing buggy, or weekend basher, this genuine Traxxas pinion gear delivers the exact specifications needed to optimise your RC car's acceleration and top speed characteristics. Traxxas has built its reputation on providing aftermarket parts that allow RC car UK owners to fine-tune their vehicles for specific track conditions, racing formats, and driving preferences, and this 12-tooth pinion gear is a perfect example of their commitment to performance customisation.

This pinion gear is manufactured to exacting tolerances using quality materials, ensuring smooth engagement with your spur gear and consistent performance lap after lap. The 48-pitch design places this gear in the sweet spot for many popular Traxxas models, including the acclaimed Ford Fiesta ST Rally series available in the UK market. Whether you're upgrading from a worn gear, experimenting with different gear ratios for improved acceleration, or building a complete new drivetrain setup, the TRX2428 gives you the control and precision that serious RC car UK enthusiasts expect from Traxxas genuine parts.

The set includes a pinion gear and set screw, providing everything you need for installation in compatible vehicles. For competitive racers and dedicated hobbyists alike, having a selection of pinion gears in different tooth counts allows you to dial in the perfect balance between acceleration and top speed for your specific racing environment, whether that's indoor carpet tracks, outdoor tarmac circuits, or grass racing venues throughout the UK.

Key Features

• 12-Tooth Design — This specific tooth count is engineered to provide a balanced gear ratio that works perfectly with Traxxas spur gears, offering improved acceleration compared to higher tooth counts whilst maintaining reasonable top speed, making it ideal for rally cars and competitive racing where quick corner exit acceleration is crucial.
• 48-Pitch Specification — The 48-pitch (48dp) standard ensures precise compatibility with Traxxas 48-pitch spur gears and drivetrain components, guaranteeing smooth meshing, reduced backlash, and minimal drivetrain wear during intensive use on UK racing circuits and bashing terrain.
• Quality Construction — Traxxas manufactures this pinion gear using hardened materials and precision machining techniques that deliver consistent performance, reliable tooth engagement, and extended service life compared to inferior aftermarket alternatives.
• Set Screw Included — The accompanying set screw provides secure fastening to your motor shaft, preventing slip during acceleration and ensuring power is transmitted efficiently to your spur gear without loss or inconsistent engagement.
• Genuine Traxxas Component — As an official Traxxas part, this gear is engineered to exact OEM specifications, ensuring it works seamlessly with your Traxxas RC car and delivers the performance characteristics Traxxas vehicles are known for in the RC hobby UK.
• Performance Tuning Control — By selecting different pinion tooth counts, you can adjust your vehicle's final drive ratio to suit specific conditions—more teeth for top speed on open circuits, fewer teeth for acceleration in technical courses with tight corners.
• 3.2mm Motor Shaft Bore — The precisely sized bore accommodates standard Traxxas brushless and brushed motor shafts, ensuring a secure fit and eliminating compatibility issues when installing this gear on your RC car.

Technical Performance

The Traxxas 12-T Pinion Gear is engineered with the same precision and attention to detail that defines all genuine Traxxas drivetrain components. At 12 teeth with a 48-pitch specification, this pinion gear represents a performance-focused choice for RC enthusiasts who want to optimise acceleration and corner-exit speed for competitive rally racing or serious hobbyist use. The 3.2mm bore is designed to fit perfectly on standard Traxxas motor shafts, creating a precise interface that minimises wobble and ensures efficient power transmission from motor to spur gear. The inclusion of a set screw means you can achieve a secure, slip-free connection that prevents the common problem of gear slippage under hard acceleration. The hardened steel or composite construction (depending on specific variant) resists tooth wear and damage, maintaining optimal mesh clearance and performance even after extensive use on rough terrain or during prolonged racing sessions. For UK RC car enthusiasts, the ability to easily swap between different pinion gear tooth counts without requiring new spur gears or major drivetrain modifications makes this an invaluable tuning component. Whether you're running a Traxxas Ford Fiesta ST Rally in red or green, or another compatible Traxxas model, this pinion gear delivers the engineering quality you expect and the performance consistency that serious competitors demand.

Frequently Asked Questions

• What Traxxas RC cars are compatible with the 12-T Pinion Gear TRX2428? — This pinion gear is compatible with Traxxas models that use 48-pitch drivetrain components, including the TRX74154-4-RED Traxxas Ford Fiesta ST Rally BL-2S Rally Car in red and the TRX74276-4-GRN Traxxas Ford Fiesta ST Rally VXL in green. It will also work with other Traxxas vehicles that feature 48-pitch spur gears and 3.2mm motor shafts. Always check your vehicle's manual or contact an authorised Traxxas retailer if you're unsure about compatibility.
• How does a 12-tooth pinion gear affect my RC car's performance compared to other tooth counts? — The 12-tooth pinion represents a mid-range option in gear ratio tuning. Compared to 10-tooth pinjons, a 12-tooth gives you higher top speed but slightly less aggressive acceleration. Compared to 14-tooth pinjons, a 12-tooth provides quicker acceleration off the line but a lower top speed ceiling. This 12-tooth sizing makes it ideal for rally racing where balanced acceleration and speed are both important for competitive lap times.
• Is the 12-T Pinion Gear suitable for beginners? — Whilst this is a genuine Traxxas component built to the highest standards, gear selection and replacement is an intermediate-level maintenance task. Beginners should ensure they're comfortable removing the motor and spur gear assembly before attempting pinion gear changes. However, if you're working with an experienced RC hobbyist or have some mechanical confidence, this genuine Traxxas part is absolutely suitable for your needs.
• What is the difference between 48-pitch and other pitch sizes? — Pitch refers to the spacing between gear teeth. 48-pitch gears have more teeth per inch than 32-pitch gears, creating smaller individual teeth that mesh more precisely. This results in smoother operation, less backlash, and better efficiency, making 48-pitch ideal for competitive racing applications. Your Traxxas vehicle is engineered specifically for one pitch size, so you must match it exactly.
• Do I need to replace my spur gear when changing pinion tooth count? — No. The beauty of pinion gear tuning is that you can adjust your final drive ratio by changing only the pinion whilst keeping your spur gear unchanged. This makes experimenting with different gear ratios affordable and convenient for UK RC racers testing setups for different track conditions.
• How do I install the set screw to secure the pinion gear? — The set screw threads into the pinion gear bore, gripping your motor shaft and preventing any slip. Ensure the pinion is fully seated on your motor shaft before tightening the set screw firmly but not excessively, as over-tightening can damage the motor shaft. Most Traxxas vehicles come with detailed assembly instructions or you can consult the manual specific to your model.
