MOOG Chassis Parts was established in 1919, when brothers Alva and Hubert P. Moog established a company to manufacture spare parts for cars and trucks. One of the fist products launched by the brothers were leaf springs, heat-treated in a special furnace. Further the company started producing the suspension and steering parts and delivering it on lines of American automakers. All products released by the company in America and Europe are subjected to a thorough testing. American concern Federal Mogul Corp., with MOOG being a part thereof, is among the ten top large-scale manufacturers of spare parts worldwide.
