This is a spare and hop-up set comprising an aluminium spur gear adapter and a 32 pitch, 65T steel spur gear supplied as a 2pcs package. The components correspond to the part references in the listing and are intended for installation on the Axial Racing Yeti XL chassis.
The aluminium adapter forms the mounting interface between the spur and axle/bearing carrier while the 65T steel spur provides the selected tooth count and pitch for this drivetrain configuration. Prior to final assembly confirm that the gearbox offers clearance for a 32 pitch gear of this size.
Fit the kit by checking pinion-to-spur mesh with the drivetrain rotated by hand before applying power, ensure the adapter compresses flush against its seating area, and keep mating faces free of debris to maintain consistent mesh and minimise gear wear.
Designed as a direct-fit replacement or an upgrade for Yeti XL drivetrain tuning; perform routine gear-mesh checks during installation.
