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

11T steel motor pinion for EXO

The GPM EX011TS is a single 11T steel motor pinion produced for Axial Racing EXO platform users, supplied as 1 pcs for RC-scale applications. Designed as a direct replacement hop-up, this pinion serves the motor-to-spur gear interface and is intended for use in 1/10 scale Axial EXO vehicles where a steel 11-tooth pinion is appropriate.

Use this part when adjusting final gear ratio for traction, acceleration, or battery/runtime tradeoffs, or when replacing a worn pinion. Installation requires matching the pinion tooth count and module to the spur gear and confirming axial alignment on the motor shaft. Check that the pinion seats fully on the motor splines and is secured with the original hex screw or locking method from your motor to avoid slippage.

As a steel pinion, the EX011TS emphasizes wear resistance at the motor interface compared with softer materials; that influences maintenance intervals and compatibility with specific spur gear materials. Before fitting, inspect motor bearings and the pinion mesh under static rotation to ensure smooth engagement without binding.
