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

This 12T steel motor pinion is an aftermarket replacement intended for use on the Axial Racing EXO platform in scale RC applications only. It installs as a direct swap for worn or damaged pinions and is a practical tuning option when changing gear mesh or final drive ratios on EXO builds.

Installation notes: check your motor shaft diameter and the pinion mounting style used on the EXO motor before fitting, clean the mating spur gear teeth, establish gear mesh with a thin gauge or approved method, and fasten the pinion following the motor maker's torque guidance. Apply thread locker only where the motor or chassis instructions call for it.

Tuning role: a steel 12T pinion gives improved wear resistance over softer materials, helping the tooth profile remain consistent during setup and repeated testing, which aids predictable drivetrain response while tuning.

Maintenance tip: inspect tooth faces after running for burrs or deformation, keep the gear clear of grit and debris, and replace the pinion at the first sign of tooth damage to protect the spur gear and motor interface.
