TRAXXAS Unlimited Desert Racer 27T Hardened Steel Pinion UDR027TS by GPM  [UDR027TS]

Technical pinion for TRAXXAS Unlimited Desert Racer motor

This precision pinion targets the TRAXXAS Unlimited Desert Racer drivetrain and is manufactured from hardened steel #45 to increase resistance to abrasive wear compared with softer gear materials.

Mounting position: pinion area. The 27T gear is supplied as a like-for-like replacement; installers should relocate the motor mount to the corresponding positioning hole referenced in the listing to maintain optimal gear engagement and backlash control.

Supplied items include the motor gear and a 4x4 set screw for shaft retention, facilitating straightforward replacement while maintaining concentricity with the spur interface.

Use this component during drivetrain tuning to reduce premature tooth wear and to preserve bearing life; recheck gear mesh under rotation and confirm motor mount alignment during final assembly to avoid load concentration on gear teeth.
