This aluminium spur gear adapter is an RC-scale replacement part supplied as a 2pcs set. It is intended to mount the spur gear on Axial Racing Yeti and Yeti XL chassis and to serve as a precise mating interface between the spur gear and the transmission area.
Use-wise, the adapter helps keep the spur gear seated and aligned with the gearbox output, which supports predictable drivetrain behaviour during rock racing and trail running. The part is aluminium, so it provides a rigid contact surface compared with softer materials.
Installation involves exchanging the existing spur gear adapter or hub for the aluminium unit and securing it in place as per the vehicle's existing fastener pattern. Because this is an RC-scale accessory, check alignment after fitting and verify mesh and clearance before running the model.
