This #45 hardened steel motor gear is supplied as a replacement pinion for TRAXXAS MAXX Monster Truck drivetrains and comes as a 2pcs set. It attaches to the motor shaft and transmits rotational force into the drivetrain, so correct gear mesh and a secure fastener are key to dependable operation.
The kit includes the pinion and a matching set screw for shaft retention. Fit this part when the factory pinion shows wear or when restoring consistent engagement between the motor pinion and the spur gear. The hardened steel construction is selected for wear resistance and reliable running under normal RC conditions.
