This spur gear is an RC-scale aftermarket component intended for TRAXXAS chassis that use the #6780 centre differential. Machined from medium carbon steel, it offers a compromise between toughness and dimensional accuracy for routine 1/10 4WD use. It is aimed at hobbyists performing maintenance, upgrades or setup changes to their centre differential assembly.
Fit this gear to replace worn plastic or softer metal parts, or to obtain a slightly firmer meshing feel that affects drivetrain response. It is fitted into the centre gear position and is designed to function with the existing differential internals without replacing the full gearbox when your model matches the compatibility list.
Basic disassembly of the centre differential is required for installation. Inspect the mating gears, bearings and shims, then reassemble carefully to preserve backlash and bearing preload consistent with your chassis tuning. Always bench-test fitment and rotate checks before on-track use.
