This aftermarket spur gear is an RC-scale centre differential component produced for compatibility with TRAXXAS platforms that use the #6780 unit. Machined medium carbon steel provides a balance of hardness and dimensional stability for centre differential service in 1/10 4WD applications. The part is aimed at technical hobbyists seeking a durable direct-fit replacement for routine maintenance and tuning.
The steel gear is used when stock plastic or softer metal gears show wear, or where a more positive engagement in the centre differential is desired to influence torque distribution and drivetrain feedback. It locates into the central gear position and is intended to function with existing differential internals when the vehicle is listed in the compatibility box.
Installation requires controlled disassembly of the centre differential, inspection of mating gear profiles and bearing condition, and methodical reassembly to ensure correct backlash and bearing preload consistent with the chassis configuration. Verify clearance and rotation on the bench before dynamic testing.
