Traxxas Spiral-Cut Differential Gears Rear Machined-Steel

Traxxas Spiral-Cut Differential Gears bring smoother meshing and increased tooth contact to the rear differential, so power moves to the wheels with less noise and less slop. These gears are aimed at builders running brushless motors or high-torque setups who want a more precise, durable drivetrain.

Key Features

• Matched 37-tooth ring gear and 13-tooth pinion gear for correct gear mesh and reliable engagement.
• CNC-machined from a solid block of steel for precise geometry and consistent strength across the set.
• Spiral-cut teeth use a slight curve to reduce backlash and promote smooth, quiet operation under load.
• Curved tooth profile increases contact area compared to straight-cut gears, improving torque transfer and tooth life.
• Specifically suited for high-torque, high-speed brushless applications where straight-cut teeth can struggle.

Technical Specifications

• Ring gear: 37 teeth
• Pinion gear: 13 teeth
• Material: Solid steel, CNC-machined
• Tooth type: Spiral-cut (curved profile to reduce backlash and increase contact area)
• Application: Rear differential use, optimized for brushless and high-torque setups

Why Choose This Product

If you want a quieter, stronger rear drivetrain that holds mesh under heavy throttle, the Traxxas Spiral-Cut Differential Gears deliver that upgrade. They fit builders who push brushless systems or run aggressive gearing and need gears that handle torque with less wear and smoother engagement.
