The GPM 40Cr Steel Motor Gear 25T is made to improve drivetrain durability on the Traxxas XRT 8S. Using hardened 40Cr carbon steel with a black hardening finish, the replacement gear gives enhanced strength and reduced wear compared with the stock gear. It includes a D-shaped motor gear hole, 25 teeth and a 9mm tooth surface width for consistent meshing with compatible motors. The gear measures 40mm across the outer diameter and fits motors that match these dimensions.
