Precision 11T Steel Pinion for Wraith

This 11T steel motor pinion suits the Axial Wraith platform and is supplied as a single aftermarket unit with the part code WR9011TS. The component is intended as a hardened replacement to provide improved wear resistance during extensive off-road operation.

Use the pinion to modify overall gearing or to renew a worn unit. Confirm motor shaft diameter and spline compatibility, establish an accurate gear mesh with the spur gear, and verify clearance and smooth rotation before running. The steel construction is selected for long service life in demanding hobby environments.

What shaft and spline specs are required?

Verify the motor shaft diameter and the spline count match the pinion bore and spline profile. Mismatched splines will prevent secure seating and cause premature wear.

How does hardness affect service life?

A hardened steel pinion resists abrasion and edge chipping better than softer alloys, reducing wear under high-load, off-road conditions and maintaining consistent gear engagement over time.

Recommended setup procedure?

Confirm fit and spline engagement, set minimal backlash with a feeler or shim method, secure the set screw to proper torque, and rotate the drivetrain by hand to ensure no binding before powering the vehicle.
