This is an RC-scale replacement drive gear produced by GPM for the Axial SCX10 platform, supplied as a single pair. The part is specified as a 20-tooth drive gear made from hard steel, intended to replace worn factory gears where increased material hardness is desired.
The gear's role is straightforward: it transmits torque from the motor pinion into the axle/spur assembly and is part of the vehicle driveline. On scale crawlers and trail rigs the selection of a harder steel drive gear helps reduce wear under heavy use and when running higher loads at low speeds.
Installation notes: verify tooth mesh and backlash after fitment, inspect mating pinion and spur for wear before reuse, and ensure the gear seats fully on its shaft. Use common RC maintenance practices when servicing the driveline, and replace bearings or retaining hardware if they show play.
