This steel #45 pinion is supplied as an aftermarket motor pinion compatible with Axial Racing Yeti and Yeti XL platforms, provided as a single unit (1 pcs). Manufactured for durability in 32 pitch drivetrains, the hardened 17-tooth design is intended to withstand frequent gear changes and tuning cycles while maintaining reliable mesh.
Recommended for ratio adjustments to refine acceleration versus top speed or for replacing worn pinions. Installation requires motor shaft access, correct axial mesh setup, and a controlled functional check to validate smooth drivetrain operation after mounting.
