About this part

Helical Gear Overview:

The Steel Helical Differential Ring and Pinion Gear for Traxxas® Mini Maxx® is a precision-machined upgrade featuring helical spiral-cut gears, which provide greater strength and smoother operation than stock bevel gears. Made from high-carbon steel, these gears are stronger, allowing for higher torque transmission with a lower tooth count.
