American Securities, a New York-based private-equity firm, is paying $750 million for HHI Group in an all-cash deal. HHI is one of North America’s leading manufacturers of highly engineered, safety-critical forged automotive components such as wheel bearings and transmission and engine components.

HHI’s forging operations, which include its FormTech, Impact Forge and Jernberg properties, was acquired from KPS Capital Partners. George Thanopoulos, CEO of HHI since its launch, will reportedly remain head of the company under American Securities.
