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

This 12-tooth steel motor pinion is an aftermarket option for the Axial Racing EXO chassis and is intended solely for RC-scale applications. It replaces damaged pinions and is useful when adjusting final drive ratios or refining gear mesh on EXO setups.

Fitting guidance: verify the motor shaft diameter and pinion mounting method used on your EXO motor, clean mating spur gear teeth before fitting, set gear mesh using a thin gauge or recommended procedure, and secure the pinion according to the motor manufacturer's torque recommendations. Only use thread locking compound where instructed by the motor or chassis documentation.

Tuning notes: steel pinions resist wear better than softer alternatives, keeping tooth geometry more consistent during tuning cycles and helping the drivetrain behave more predictably under repeat testing.

Care advice: after runs, check tooth faces for deformation or burrs, remove any debris from the gear, and swap the pinion at the first sign of damage to prevent accelerated wear to the spur gear or motor pinion interface.
