Key Features

• 18-Tooth Steel Top Gear — The hardened steel construction of the 18-tooth top gear delivers exceptional durability and resistance to wear, ensuring your RC car maintains consistent power delivery even after extensive use. Steel gears provide superior strength compared to plastic alternatives, which means less slippage, better engagement with the drive train, and a longer service life for your brushless RC vehicle.
• Genuine Traxxas OEM Component — This is an official Traxxas spare part, which means it's manufactured to the exact specifications required for your RC model. Using genuine OEM components ensures compatibility, reliability, and performance that third-party alternatives simply cannot match, and it protects your investment in your RC car.
• Precision-Engineered Input Shaft — The input shaft is manufactured to tight tolerances, ensuring smooth engagement and minimal backlash in your drivetrain. This precision engineering translates directly to better acceleration response and more predictable handling characteristics in your ready to run RC vehicle.
• Drivetrain Spare Part Classification — This component is specifically designed as a drivetrain spare, meaning it addresses one of the most critical systems in your RC car. A well-maintained drivetrain with quality components like this TRX3992 assembly is the foundation of reliable, high-performance RC driving.
• Direct Replacement Option — If your current input shaft or drive gear assembly has worn out or been damaged, the TRX3992 serves as a direct replacement, allowing you to restore your RC car to its original specifications without modification or adjustment of other components.

Technical Performance

The Traxxas Input Shaft/Drive Gear Assembly TRX3992 represents the engineering standard that Traxxas has established across their entire RC vehicle range. The 18-tooth steel top gear is the centrepiece of this assembly, and steel was chosen specifically for its superior hardness and wear resistance. When you're running a brushless RC car at high speeds or putting sustained power through the drivetrain during competitive use, the quality of your gears directly impacts performance and longevity. The precision-engineered input shaft ensures that power is transmitted smoothly from the motor to the rest of the drivetrain without unnecessary losses or vibration. This assembly is engineered to work seamlessly with Traxxas drivetrain systems, maintaining the precise geometry and tolerances that Traxxas vehicles are known for. Whether your RC car is a 1/10 scale model or a larger format vehicle, the TRX3992 brings the same manufacturing quality and performance reliability that professional racers and serious hobbyists depend on. The hardened steel gear teeth resist stripping and damage far better than plastic gears, which is especially important if you regularly run at high throttle or engage in competitive RC racing on UK tracks and bash sites.
