Technical Performance
The Traxxas TRX9579R differential gear set represents the pinnacle of Traxxas engineering for 1:8 scale brushless monster truck applications. The machined construction is a significant upgrade over stamped alternatives, offering superior precision tolerances that result in smoother gear meshing, reduced backlash, and more efficient power transfer from your brushless motor to the wheels. The 37-tooth ring gear paired with the 13-tooth pinion gear creates a carefully calculated gear ratio that's been proven in countless Sledge Belted applications worldwide. This ratio provides an excellent compromise between acceleration response and top-end speed capability, making it suitable for a wide variety of driving conditions from high-speed bashing to more technical terrain navigation. The machined material specification ensures these gears can withstand the torque demands of modern brushless systems without chipping or stripping, even under extreme driving loads. For drivers running high-KV brushless motors and premium LiPo batteries in their Sledge, upgrading to these machined differential gears is a smart investment in drivetrain longevity and performance consistency. The front or rear application versatility means you can address specific drivetrain issues or implement a complete differential upgrade strategy that works within your tuning philosophy.

- 37-tooth ring gear (machined)
- 13-tooth pinion gear (machined)
Frequently Asked Questions
- What is the gear ratio provided by the 37-tooth ring and 13-tooth pinion? — The gear ratio is approximately 2.85:1 (37÷13), which provides excellent acceleration and mid-range power delivery whilst maintaining reasonable top speed capability. This ratio is specifically engineered for the Traxxas Sledge Belted 1:8 monster truck platform and works in harmony with the truck's drivetrain characteristics.
- Can I use the TRX9579R for both front and rear differentials? — Yes, this component is specifically designed for either front or rear differential applications, giving you flexibility in your upgrade strategy. Many enthusiasts upgrade one axle at a time or maintain a complete matching set throughout their drivetrain for consistent performance characteristics.
- Why should I upgrade to machined gears instead of staying with standard gears? — Machined gears offer superior precision, reduced backlash, smoother operation, and enhanced durability compared to stamped alternatives. If you're running a brushless motor with modern high-capacity LiPo batteries, upgrading to machined differential gears provides better longevity and more consistent performance, particularly during aggressive bashing or competitive driving.
- What Traxxas models are compatible with the TRX9579R? — The Traxxas TRX9579R is compatible with all Traxxas Sledge Belted variants including the TRX95096-4-GRN (Green), TRX95096-4-RED (Red), TRX95096-4-BLUE (Blue), and TRX95096-4-ORNG (Orange) 1:8 4WD Brushless Electric Monster Trucks.
- Is this a difficult installation for someone new to RC truck maintenance? — Whilst differential gear replacement is considered an intermediate maintenance task, Traxxas designs all their components with user serviceability in mind. If you're comfortable performing basic RC truck maintenance like battery charging and tyre changes, you should be able to handle differential service with the Traxxas manual and a few basic tools. However, if you're completely new to RC maintenance, visiting an experienced RC hobbyist or local RC Model Shop specialist can help ensure correct installation.
- How often should I replace my differential gears? — With proper maintenance and appropriate driving style for your components, machined gears like the TRX9579R can last hundreds of hours of driving. However, if you notice grinding noises, excessive slipping, or reduced acceleration response, these are signs that differential service is needed. Regular inspection during routine maintenance helps identify wear early.
