Axial Yeti/Yeti XL 32p 19T Pinion YT019TS Hardened Steel Upgrade by GPM  [YT019TS]

19T hardened pinion for Yeti drive systems

This steel 19 tooth pinion is offered as a single aftermarket replacement for Axial Yeti and Yeti XL 32 pitch drivetrains. It provides a hardened 19T choice for users wanting to change final ratio or fine tune mesh without altering the motor or spur gear.

Installation is routine for those who know motor removal and gearmesh adjustment: remove the motor, fit this 19T pinion, then set mesh using shims or an adjustable mount. Manually rotate the drivetrain to check for smooth engagement and a small uniform clearance to avoid premature tooth damage.

Choosing 19T typically yields a slight increase in top speed relative to larger pinions while keeping adequate torque for rock racing. The steel construction improves wear characteristics and retains tooth geometry under stress; pairing with quality motor bearings and a matched 32 pitch spur produces the best long term results.

Sold as 1pcs, this part suits hobbyists maintaining or tuning Axial Yeti and Yeti XL scale rock racers and is compatible with standard 32 pitch spur gear pairings for those kits.
