Axial Racing Yeti Steel #45 Pinion Gear 32 Pitch 20T by GPM YT020TS  [YT020TS]

Motor pinion for Yeti series

This is a single steel pinion gear made for Axial Yeti and Yeti XL applications, supplied as a 1pc set. Constructed in #45 steel with a 32 pitch and 20T tooth count, it is intended as a direct replacement or a gearing option when modifying final drive ratio. The part is sold by GPM under part code YT020TS and matches the 32-pitch spur gear systems used on the specified chassis.

Installation and tuning notes: confirm the pinion's 32-pitch specification matches your spur gear before fitting, inspect gear mesh and backlash after installation, and run a short break-in at low load to verify smooth engagement. Swapping to a 20T pinion will raise motor rpm and reduce torque at the wheels compared with larger-tooth options, so choose tooth count based on track or terrain needs.

Material and role: as a #45 steel pinion, the gear prioritizes durability for frequent use and abrasive conditions, serving as a durable interface between the motor and the Yeti drivetrain without changing other drivetrain components.
