This aftermarket medium carbon steel spur gear is made to mate with the #6780 center differential assembly on compatible 1/10 scale TRAXXAS 4WD machines. It acts as the middle differential large gear for routine drivetrain service, repairs or strength-focused upgrades where a steel component is preferred over factory materials.
Fitment and operation are specific to the TRAXXAS models listed below. Install the gear into the center differential carrier using standard differential assembly procedures, check gear mesh and bearing seating, and set backlash to the manufacturer's baseline before running. Use this part when a direct replacement matching the #6780 position and steel material is required.
