This 12-tooth steel motor pinion is an RC replacement part intended for Axial Wraith platforms and is supplied as 1 pcs. It is used to change final drive ratios where altering tooth count adjusts low-speed driveability and acceleration.
Steel material choice emphasises wear resistance under continuous mesh contact, and the 12T count is commonly selected to favour torque and control over top speed in trail and rock crawling scenarios.
Fitting notes: press the pinion onto the motor shaft so the set screw can seat fully, check side-to-side alignment against the spur gear, and verify clearance under load. Conduct a cautious low-speed run to ensure the drivetrain is quiet and running cool.
Supplied: 1 pcs, steel 12T motor pinion, single-piece pack.
