Axial Yeti/Yeti XL 32 Pitch 19T Steel Pinion YT019TS by GPM  [YT019TS]

Hardened 19T pinion for Yeti drivetrains

This aftermarket steel 19T pinion is made to fit Axial Yeti and Yeti XL 32 pitch systems and is sold as a single replacement item. It is a direct motor pinion option for hobbyists who need a hardened 19 tooth gear to tweak final drive ratio or refine gearmesh without changing the motor or main spur gear.

Installation is straightforward for anyone comfortable with basic motor removal and gearmesh checks: remove the motor, replace the existing pinion with this 19T steel gear, then set mesh using shims or an adjustable motor mount. Rotate the drivetrain slowly to confirm there is no binding and that a slight, even backlash remains to prevent premature wear.

In tuning scenarios a 19T pinion gives a small top speed increase compared with larger-tooth options while retaining usable torque for scale rock racing. As a steel pinion it is selected for wear resistance and consistent tooth form under load; pairing it with quality motor bearings and a matching 32 pitch spur yields the best durability and efficiency.

Sold as 1pcs, this pinion suits hobbyists maintaining or tuning Axial Yeti and Yeti XL rock racers and matches typical 32 pitch spur gear combinations for those kits.
