Axial Racing EXO 12T Steel Motor Pinion by GPM EX012TS  [EX012TS]

This steel 12T motor pinion is an aftermarket replacement manufactured by GPM for the Axial Racing EXO platform, intended for RC-scale use only. It provides a direct swap for worn or damaged pinion gears and serves as a tuning option when adjusting gear mesh and final drive ratios on EXO setups.

Installation notes: confirm motor shaft diameter and pinion mounting style on your EXO motor before fitting, clean the mating spur gear teeth, set gear mesh with a thin gauge or approved method, and secure the pinion per the motor manufacturer’s torque guidance. Use thread locker only where specified by the motor or chassis instructions.

Tuning role: a steel pinion offers wear resistance compared with softer materials, helping maintain consistent tooth profiles during testing and regular use, which supports repeatable gear mesh and more predictable drivetrain behavior during tuning sessions.

Maintenance tip: inspect tooth faces for burrs or deformation after running, keep the gear free of debris, and replace the pinion if any tooth damage appears to avoid accelerated wear to the spur gear or motor pinion interface.
