Abstract: A method of cold forming an outer arm of a rocker arm assembly in a cold forming machine includes providing a slug having a first end and a second end, extruding the slug at the first end to establish two different widths of the slug, compressing the slug to form an upper angled surface and a lower angled surface at the second end, and compressing the slug to form an inner arm window defined by a pair of side walls and a pair of end walls.
