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

Steel 19 tooth pinion tailored for Yeti rigs

This aftermarket steel 19T pinion is supplied as a single replacement for Axial Yeti and Yeti XL 32 pitch drivetrains. It is intended as a hardened motor pinion option when a 19 tooth, 32 pitch gear is needed to tune final drive ratio or to refine gearmesh without changing the motor or spur gear.

Fitting is straightforward for competent hobbyists: remove the motor, replace the original pinion with this 19T steel unit, then set the mesh using shims or an adjustable motor mount. Rotate the drivetrain by hand and check there is no binding and that a small consistent backlash remains to protect the gear teeth.

In setup terms the 19T count nudges top speed higher than larger pinions while keeping usable torque for rock racing tasks. The steel construction focuses on wear resistance and predictable tooth engagement under load; it pairs best with quality motor bearings and a matching 32 pitch spur for dependable performance.

Offered as 1pcs, this pinion is suitable for hobbyists maintaining or tuning Axial Yeti and Yeti XL scale rock racers and fits standard 32 pitch spur configurations for those models.
