Axial EXO 11T Hardened Steel Motor Pinion EX011TS by GPM  [EX011TS]

EXO 11T steel motor pinion

The EX011TS is a single 11-tooth steel motor pinion intended for Axial EXO platform applications, provided as 1 pc for 1/10 scale RC models. It functions as a direct replacement hop-up for installations calling for an 11T steel pinion at the motor-spur interface.

This part is useful when adjusting final drive ratios to favour traction, top speed or battery economy, or when replacing a worn pinion. Ensure the tooth count and module align with your spur gear and that the pinion is correctly positioned on the motor shaft. Secure the pinion with the motor's original screw or locking system to avoid loosening in use.

As a steel component, the EX011TS increases wear resistance at the motor connection relative to softer alternatives, which may affect maintenance schedules and spur compatibility. Before operating the vehicle, inspect motor bearings and confirm the pinion mesh by rotating the drivetrain by hand to check for smooth, binding-free engagement.
