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

Aftermarket carbon steel spur for TRX4 platforms

This carbon steel spur gear is an aftermarket replacement made for scale Traxxas TRX4 vehicles to carry drivetrain torque beside the motor pinion. It keeps the same tooth count as the original large gear so gear mesh and centre distance remain unchanged and no gearbox geometry changes are required.

The component is aimed at hobby crawling use and routine maintenance tasks like swapping a worn main gear or repairing a damaged unit. Its carbon steel build emphasises wear resistance and dimensional stability under typical RC drivetrain loads rather than full-size vehicle conditions.

As a direct-fit replacement for TRX4 and TRX6 main gears where tooth count matches the original, this carbon steel spur offers a simple repair option for 1/10 scale electric crawlers and preserves original gear mesh for straightforward rebuilds.
