This hop-up set is an RC-scale replacement and upgrade pack featuring an aluminium spur gear adapter matched to a 32 pitch, 65T steel spur gear, supplied as a 2pcs set. The items match the part references shown in the listing and are intended for use on the Axial Racing Yeti XL platform.
The adapter creates the mounting interface between the spur gear and the axle or bearing carrier, while the 65T steel spur provides the tooth count and 32 pitch required for this gearbox arrangement. During installation confirm there is sufficient clearance inside the stock gearbox for a 32 pitch spur of this diameter and that the adapter aligns with its mating faces.
When fitting the set, check pinion-to-spur mesh by rotating the drivetrain by hand before applying power, verify the adapter sits flush, and keep bearings and gearbox faces clean to maintain consistent mesh and to reduce premature wear of gear teeth.
This 2pcs set is intended as a direct-scale accessory for parts replacement or drivetrain tuning on the Axial Racing Yeti XL chassis; follow standard gear-mesh checks during installation.
