This aluminium differential housing is an aftermarket replacement meant for the Axial platforms shown in the title. It replaces the stock plastic shell with aluminium to improve structural strength and maintain a steady gear mesh during scale off-road use.
Function in the driveline: the housing locates gears and bearings, keeps gear geometry stable under torque, and provides a secure mounting point for the differential. Swapping plastic for aluminium reduces flex at fixation points and helps achieve more predictable setup and tuning results.
Installation guidance: the part installs in the same location as the original differential shell and reuses your Axial internal gears and bearings. Basic hand tools will handle removal and refit, and a careful gear mesh check is advised before first run.
