This aftermarket 66-tooth, 32-pitch spur is specified for the Axial Yeti drivetrain and is manufactured from steel #45. It provides a hardened replacement to softer factory spurs, intended for hobbyists seeking longer service life and predictable gear ratio changes.
The component alters final drive ratio when installed, making it suitable for tuning top speed versus acceleration; installation requires verification of 32-pitch mesh and correct centre mount alignment to avoid premature wear.
For teams or hobbyists focused on drivetrain durability and controlled gearing changes on an Axial Yeti, this steel 66T spur is a practical upgrade; confirm mesh and clearances before operational use.
