This GPM Steel 11T Pinion Gear is CNC focused in concept and built for longevity in the Traxxas TRX4. Fabricated from hardened steel #45, it provides a firm, wear resistant interface between motor output and drivetrain input.
Designed to align precisely with standard motor shafts of the specified diameter to ensure consistent tooth contact and reduced backlash. Proper installation will help protect motor bearings and support predictable power transfer under load.
