Available from RC Model Shop, the UK's trusted independent RC retailer, this genuine Traxxas component comes with the assurance that you're purchasing authentic quality. Whether you're new to the RC hobby or an experienced basher preparing for the next competition, understanding your drivetrain components like this pinion gear is fundamental to getting the best from your brushless RC truck or crawler.

Key Features

• Heavy Duty Hardened Steel Construction — This pinion gear is manufactured from hardened steel, which means it resists wear, deformation, and tooth stripping far better than standard materials. For RC drivers in the UK who push their vehicles hard, this durability translates to longer service life and fewer replacement cycles, saving money and downtime over the long term.
• 14-Tooth Configuration — The 14-tooth design provides a specific gear ratio that influences your vehicle's acceleration and top speed characteristics. This tooth count is optimised for many popular RC models and offers a balanced approach to performance across various driving conditions and terrain types.
• 32-Pitch Gear Standard — Operating to the 32-pitch standard ensures compatibility with a wide range of RC vehicles, particularly Team Associated MT10 models and various Traxxas platforms including the Rustler Ultimate VXL 4x4 and TRX-4 crawler ranges. This standardisation means you can confidently upgrade or replace your pinion gear knowing it will fit correctly.
• 3.2mm Bore Diameter — The precisely machined 3.2mm bore ensures a secure fit on your vehicle's motor shaft, eliminating wobble and ensuring smooth, consistent power delivery to the drivetrain. Proper bore sizing is crucial for reliable gear mesh and preventing premature wear.
• Genuine Traxxas Component — As an original Traxxas part, this pinion gear has been tested and approved for use on multiple RC platforms, giving you confidence that it meets the manufacturer's exacting standards for quality and performance compatibility.
• Wide Compatibility Range — This gear is compatible with an extensive array of RC vehicles including the Associated Rival MT10 Brushless RTR Truck, MT10 Classic Truck Kit, TRX-4 2021 Ford Bronco in multiple colours (White, Red, Black, Orange), TRX-4 Defender 4WD RTR variants, and the Traxxas Rustler Ultimate VXL 4x4 in both Blue and Green. This broad compatibility makes it an excellent investment if you operate multiple RC platforms.

Technical Performance

The Traxxas 14-T Pinion Gear represents a precision-engineered drivetrain component designed for RC vehicles that demand reliable power transmission. At 14 teeth with a 32-pitch specification, this gear operates within the established standard for small-scale RC transmissions used across brushless and high-performance electric RC trucks and crawlers. The hardened steel material elevates this beyond consumer-grade options, providing superior resistance to the cyclic stresses that occur during acceleration, cornering, and aggressive driving. The 3.2mm bore has been precisely machined to tolerance specifications that ensure minimal play when installed on compatible motor shafts, reducing vibration and maximising the efficiency of power transfer from your brushless motor to the drivetrain. For RC enthusiasts in the UK operating vehicles like the Traxxas Rustler Ultimate VXL 4x4 — a highly capable brushless 1/10 scale short course truck — or the TRX-4 crawler range, this pinion gear works in concert with your spur gear to establish your vehicle's gear ratio. The specific 14-tooth count represents a middle ground in the performance spectrum; it provides reasonable acceleration while maintaining respectable top-end speed capability. When paired with appropriate spur gears and motor configurations, this pinion enables smooth, efficient power delivery across a range of driving scenarios from technical crawling to high-speed bashing. The hardened steel construction means this gear will maintain its tooth profile through hundreds of hours of operation, resisting the micro-fractures and deformation that can occur in standard materials under sustained load.

Frequently Asked Questions

• Is the Traxxas 14-T Pinion Gear compatible with my RC truck? — This gear is compatible with a wide range of Team Associated and Traxxas models including the Associated Rival MT10 Brushless RTR, MT10 Classic, MT10 Factory Team Kit, Traxxas Rustler Ultimate VXL 4x4, and the entire Traxxas TRX-4 crawler range including the 2021 Ford Bronco and TRX-4 Defender models. If you own one of these vehicles or any other RC model that specifies a 32-pitch, 14-tooth pinion with a 3.2mm bore, this gear will be compatible. Always verify your vehicle's specifications before ordering to ensure correct fitment.
• What is a pinion gear and why do I need to replace it? — A pinion gear is a small toothed wheel that meshes with your vehicle's spur gear to transmit power from the motor to the drivetrain. Over time and with use, pinion gears can wear, developing flat spots or broken teeth, which compromises power delivery and efficiency. Replacing a worn pinion with fresh hardened steel like this Traxxas component restores optimal performance and prevents further damage to your spur gear.
• What is the difference between 14-tooth and 13-tooth pinion gears? — Tooth count directly affects your vehicle's gear ratio. A 14-tooth pinion paired with a specific spur gear size will produce a different ratio than a 13-tooth pinion with the same spur. The 14-tooth configuration generally offers slightly lower top-end speed but quicker acceleration compared to 13-tooth alternatives. Traxxas offers both options (TRX3944X for 14-tooth and TRX3943X for 13-tooth) to allow tuning of your vehicle's performance characteristics.
• Is hardened steel really better than standard steel for RC gears? — Yes, significantly. Hardened steel undergoes a heat treatment process that increases its hardness and wear resistance. This means the tooth profile maintains its shape longer under the repetitive stress of driving, reducing the likelihood of tooth stripping and extending the overall lifespan of the gear. For serious RC drivers in the UK, this superior durability justifies the investment.
• What is 32-pitch gearing? — Pitch refers to the size of the gear teeth and the spacing between them. 32-pitch gears are smaller, more precisely spaced teeth designed for smaller-scale RC vehicles like 1/10 scale trucks and crawlers. This standard is widely used across the industry and allows for smooth, efficient power transmission in compact drivetrain packages. Ensuring your replacement pinion matches your spur gear's pitch specification is essential for proper meshing and performance.
• How do I install this pinion gear? — Installation involves removing your motor from the vehicle, sliding off the old pinion gear from the motor shaft, and sliding on the new TRX3944X pinion. The 3.2mm bore should fit snugly on your motor shaft. Most Traxxas motors and compatible alternative motors use this standard shaft size. Always consult your vehicle's manual for specific removal and installation procedures, and ensure the pinion is fully seated on the shaft before reinstalling your motor.
