This hardened steel #45 motor gear is manufactured as a replacement pinion for TRAXXAS MAXX Monster Truck drivetrains and is supplied as a 2pcs set. It mounts to the motor shaft and transmits rotation into the drivetrain, so correct mesh and a secure mounting are essential for reliable performance.
The set includes the gear and a matching set screw for shaft retention. Fit this part when the original pinion shows wear or when you need to restore consistent engagement between the motor pinion and the spur gear. The hardened steel build focuses on wear resistance and steady running under normal RC use.
