This single aftermarket spur gear is made for the Axial Yeti platform and is specified as a 66-tooth, 32-pitch unit formed from steel #45. It is a direct replacement option for compatible Yeti drivetrains where a tougher steel spur is preferred over softer materials.
The spur sits in the model drivetrain and alters final drive ratio when swapped with other tooth counts. Use this 66T steel spur to trade acceleration for higher top speed or to extend service life in heavy-use rock racer setups.
If you need a straightforward, scale-correct steel spur to tweak gearing or increase drivetrain longevity on an Axial Yeti, confirm 32-pitch mesh and center mount alignment before fitting.
