Overview
The Traxxas Ring gear, differential / pinion gear, differential TRX9579 is an essential drivetrain spare part designed for owners of the Traxxas Sledge Belted 1:8 4WD Brushless Electric Monster Truck. Whether you are an experienced RC enthusiast running a competitive setup or a weekend basher pushing your monster truck to its limits, this genuine Traxxas differential gear set is the perfect replacement component to keep your RC car UK ready for action. The differential is one of the most critical components in any RC vehicle's drivetrain, and maintaining it with quality OEM parts ensures your Sledge performs at its peak.
Differential gears are responsible for distributing engine power to the wheels whilst allowing them to rotate at different speeds during cornering, which is essential for smooth handling and traction. Over time, through regular use, bashings, and competitive racing, these gears can wear or become damaged, requiring replacement. The Traxxas TRX9579 is the genuine OEM part specified for your Sledge, ensuring perfect fitment, durability, and performance characteristics that match the original engineering specifications.
As a UK RC retailer, we understand the importance of having access to genuine spare parts that keep your brushless RC vehicles running smoothly. This differential ring and pinion gear set is in stock and ready to ship, with free mainland UK delivery on orders over £99. Whether you need to refresh your Sledge's drivetrain or repair damage from an accident, this is the authentic Traxxas component you need.
Key Features
- 37-tooth Ring Gear — The ring gear provides the primary load-bearing interface in the differential assembly, and the 37-tooth count is specifically engineered for the Sledge's performance envelope to deliver responsive acceleration and balanced handling characteristics.
- 13-tooth Pinion Gear — The pinion gear meshes with the ring gear to create the final drive ratio, and the 13-tooth specification ensures optimal power delivery and efficiency for the Sledge's 1:8 scale brushless electric drivetrain.
- Genuine OEM Traxxas Part — This is the authentic manufacturer component, not an aftermarket substitute, guaranteeing that every tooth profile, material composition, and dimensional tolerance matches Traxxas engineering standards perfectly.

Technical Performance
The Traxxas Ring gear, differential / pinion gear, differential TRX9579 represents OEM engineering excellence for one of the most advanced 1/8 scale brushless RC monster trucks on the market. The Sledge Belted is renowned for its raw power delivery and aggressive off-road performance, which places significant demands on the drivetrain components. The 37-tooth ring and 13-tooth pinion gear combination creates a carefully calculated gear ratio that balances the output of the brushless motor with wheel speed and traction characteristics. The materials used in these gears are selected for their strength-to-weight ratio, allowing them to handle the peak torque outputs generated by modern brushless systems without excessive mass penalty. The precision manufacturing ensures that tooth engagement is smooth and efficient, minimising drivetrain losses and maximising power transfer to the wheels. Whether you are running the Sledge on technical rock gardens, high-speed desert runs, or competitive racing environments, these differential gears form the critical interface between the motor and the wheels. Genuine Traxxas parts like this ensure that your brushless RC investment remains reliable, consistent, and predictable in all driving conditions.
