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

This steel 12T motor pinion is offered as an aftermarket replacement for the Axial Racing EXO platform and is for RC-scale use only. It is a direct swap candidate for worn pinions and a straightforward tuning choice when changing gear mesh or overall drive ratio on EXO cars.

Fitment checklist: confirm your motor shaft diameter and the pinion mounting style before installation, clean the mating spur gear teeth, set gear mesh with a thin gauge or the approved technique, and tighten the pinion to the motor maker's recommended torque. Use thread locker only where specified by the motor or chassis instructions.

Tuning benefits: a steel pinion tends to resist wear better than softer options, preserving tooth geometry across tuning sessions and delivering steadier drivetrain behaviour as you test different setups.

Service note: inspect the pinion teeth for burrs or distortion after runs, keep the gear clear of grit and foreign matter, and replace any pinion with damaged teeth to avoid increased wear on the spur gear and motor pinion interface.
