This replacement motor pinion fits the TRAXXAS Unlimited Desert Racer platform and is made from hardened steel #45 to improve longevity compared with standard gears.
Installation point: pinion area. The gear is 27T and supplied as a direct swap; the listing notes the original was 127T, so adjust the motor mount to the corresponding hole to achieve proper alignment.
The package contains the motor gear and a 4x4 set screw, suitable for straightforward pinion replacement and securing the gear to the motor shaft.
Choose this pinion to strengthen the drivetrain during setup and to reduce premature tooth wear on varied surfaces; always check mesh and motor mount positioning to protect bearings and the spur interface.
