This aftermarket steel motor gear is produced for TRAXXAS 1/8 X-Maxx owners who need a direct replacement motor pinion. Sold as 1 pcs, the unit matches the 15T tooth count indicated in the product title and is intended for use on the motor output of the X-Maxx platform.
As a steel pinion, the part focuses on wear resistance compared with common plastic pinions and serves the drivetrain role of transferring torque from the motor to the spur gear. Keep in mind this is an RC-scale component made for the 1/8 X-Maxx, do not use it on real vehicles.
Installation and tuning notes: replace worn motor pinions with the same tooth count to preserve gear ratio, fit the pinion to the motor shaft using the existing fastening method on your motor, then set and verify gear mesh before running. Check that the motor shaft diameter and mounting method match the pinion on your X-Maxx prior to fitting.
