TRAXXAS #6780 Centre Spur Gear Medium Carbon Steel FR1200/G1 by GPM  [FR1200/G1]

Aftermarket spur gear for TRAXXAS centre diff units

This spur gear is a purpose-made RC aftermarket centre differential component for TRAXXAS platforms that use the #6780 unit. Made from medium carbon steel, it is intended to improve wear life and maintain tooth form under 1/10 4WD drivetrain loads. The component is suited to hobby-level maintenance, setup and upgrade tasks on compatible trucks and buggies.

Use this steel gear to replace worn factory plastic or softer metal parts, or to tune centre differential engagement characteristics. It installs at the central gear position and is designed to work with existing differential internals without requiring a full gearbox change when the chassis is confirmed compatible.

Installation involves standard centre differential disassembly, gear and bearing inspection, and careful reassembly to retain correct backlash and bearing preload for the chassis configuration. Validate fitment and smooth rotation on the bench prior to full-speed trials.

Provided as a direct-fit aftermarket replacement for the listed TRAXXAS centre differentials, this medium carbon steel spur gear aims to extend service life while maintaining original fit and alignment.
