GPM EX013TS Steel Motor Pinion (13T) for Axial Racing EXO, steel pinion, 1 pcs  [EX013TS]

13T Steel Motor Pinion for Axial EXO

This steel motor pinion is offered as a direct replacement pinion for Axial Racing EXO scale models, presented as a single unit (1 pcs). It is a simple, serviceable part intended for use in the motor-to-spur gear train of electric RC models where a 13T pinion is required.

Installation requires proper motor-to-spur gear mesh. When fitting, mount the pinion onto the motor shaft and align the motor so the pinion and spur mesh cleanly without excessive play or binding. Secure the pinion per your motor's fastening method and verify rotation under low load before full operation.

In tuning terms, swapping to this 13T steel pinion changes the drive ratio relative to your current pinion and spur combination; use it when you need a specific ratio for crawling or traction-focused setups. As with any steel pinion, check mating spur gear condition and inspect for wear regularly to avoid accelerated wear on either gear.
