TRX4 Carbon Steel Main Spur Gear TRX4045TS by GPM  [TRX4045TS]

Replacement carbon steel spur for TRX4 crawlers

This carbon steel spur gear is an aftermarket spare designed for Traxxas TRX4 platforms to transfer drivetrain power from the motor pinion. It uses the same tooth count as the factory large gear so centre distance and mesh are maintained without altering the gearbox layout.

Made for hobby crawling duties and routine repairs such as replacing a worn gear, the part focuses on wear resistance and stable dimensions under typical RC use rather than any real-world vehicle loads.

As a like-for-like replacement spur for TRX4/TRX6 models where the tooth count matches, this carbon steel gear provides a reliable swap option for 1/10 scale electric crawlers and helps restore drivetrain function quickly.
