Having a quality, properly functioning front differential makes the difference between smooth, predictable handling and unpredictable behaviour on the track or off-road course.
Key Features
- Pro Built® Complete Assembly — This differential comes fully assembled from the factory, meaning you don't need to source individual components, spend time building it, or worry about assembly errors. You simply remove it from the box and install it into your model, saving time and ensuring perfect factory-quality assembly every single time.
- Integrated Differential Pinion Gear — The pinion gear is included as part of the complete assembly, giving you everything needed for proper drivetrain function. This eliminates the need to purchase additional gears separately and ensures perfect compatibility between all differential components.
- Precision Bearings Included — Quality bearings are essential for smooth, efficient rotation and long component lifespan. These precision bearings are pre-installed and ready to perform, reducing friction and ensuring your differential operates at peak efficiency from the moment you install it.
- 8S Brushless Compatibility — Purpose-built for the demands of 8S LiPo brushless power systems, this differential is engineered to handle the extreme torque and power output that modern brushless motors deliver. This makes it ideal for high-performance RC monster trucks that demand reliable drivetrain components.
- Official Traxxas Genuine Part — As an authentic Traxxas spare part with the official TRX7880 designation, you're guaranteed genuine quality, correct specifications, and perfect compatibility with your X-Maxx 8S or XRT model.
- Multiple Model Compatibility — This single part fits a range of Traxxas 8S models including the X-Maxx Belted 4WD Brushless RTR in various colours (orange, blue, red, green), the X-Maxx Ultimate variants, X-Monster chassis models, and the complete XRT VXL-8S lineup in all available colours, as well as XRT Ultimate versions.
Technical Performance
The Traxxas TRX7880 front differential represents the pinnacle of drivetrain engineering for large-scale RC monster trucks.
