The 4pcs gear set is supplied for installation inside the TRAXXAS E-MAXX differential housing and is fabricated from hardened steel #45 to provide improved wear resistance for internal drivetrain components.
These gears are intended for use when replacing fatigued or damaged stock internals or when tuning for firmer differential reaction. They are specified as compatible with the E-MAXX differential assembly and support consistent operation under typical running stresses.
Fitment advice: inspect the differential housing and bearing surfaces, ensure cleanliness, and assemble to the TRAXXAS E-MAXX chassis service procedure to establish correct gear mesh and reliable function.
A precision replacement aimed at hobbyists who require hardened internals for improved wear resistance and predictable differential response.
