Key Features

• Genuine Traxxas OEM Component — These are authentic manufacturer parts designed and engineered by Traxxas, the world's leading manufacturer of ready to run RC models. Using genuine spares ensures perfect fitment, reliability and longevity compared to aftermarket alternatives.
• 13-Tooth Pinion Gear — The pinion gear is the smaller gear in the differential assembly that drives the larger ring gear, and the 13-tooth specification is precisely engineered for optimal power delivery and acceleration in front-wheel differential applications.
• 37-Tooth Ring Gear — The larger ring gear works in conjunction with the pinion to distribute power and create the correct gear ratio, and the 37-tooth configuration is specifically designed for the Traxxas Mini Rally VXL and Mini Slash BL-2S platforms.
• Front Planetary Differential System — The planetary differential design allows for smooth power distribution between front wheels during acceleration and cornering, which is essential for maintaining traction and control during competitive racing and high-speed driving.
• Precision Engineered Materials — These gears are manufactured from high-quality materials selected for their durability and wear resistance, ensuring they can handle the stresses of brushless motor power and aggressive driving styles without premature failure.
• Easy Installation — As replacement components, these gears are designed to drop directly into your existing RC vehicle's differential assembly, making maintenance and repairs straightforward for RC enthusiasts of all experience levels.
• Compatible with Multiple Models — These gears are engineered to work with the entire Traxxas Mini Rally VXL family (standard, grey and red versions) as well as the Mini Slash BL-2S 4X4 RTR short course truck in all colour options (yellow, orange, pink and green).

Technical Performance

The Traxxas 13/37 Front Planetary Differential Ring & Pinion Gears represent precision engineering at its finest, combining high-quality materials and manufacturing tolerances to deliver reliable performance in demanding RC applications. The 13-tooth pinion and 37-tooth ring gear combination creates a specific gear ratio that has been carefully calculated by Traxxas engineers to provide optimal power delivery for the Mini Rally VXL and Mini Slash BL-2S platforms. These vehicles utilise brushless motor technology paired with modern electronic speed controllers (ESCs), and the differential gears are engineered to handle the consistent, reliable power delivery that brushless systems provide. The planetary differential design is particularly effective in front-wheel applications, as it allows for intelligent power distribution that improves traction during acceleration whilst also permitting differential wheel speeds during cornering for superior handling characteristics. Whether you're running a 3S LiPo battery setup or pushing higher-voltage configurations, these gears are built to withstand the torque and rotational forces generated by modern brushless RC systems. The precision engineering and quality materials used in their manufacture ensure extended service life compared to inferior replacement options, making them an excellent investment for serious RC competitors and dedicated enthusiasts who maintain their vehicles to competition standards.
