The GPM Harden Steel #45 front, center, and rear differential gear set is an 8-piece kit engineered to replace common wear items and improve overall drivetrain durability in the TRAXXAS MAXX Monster Truck.
Using Harden Steel #45, these gears resist wear and maintain tooth profiles longer than softer materials, reducing the frequency of replacements.
Precision cutting and consistent tolerances help reduce backlash and create more efficient power transfer from motor to wheels.
