Jahns Racing Pistons 1947 Sticker

William Jahns Sr. founded W.H. Jahns Co. in 1912 in Los Angeles where he turned out pistons for literally every application. When Jahns Sr. retired in 1948, he left the business to his son, William Jahns Jr., though Junior had already started his own business on the side under the name of Jahns Racing Pistons a year prior. Being much more interested in racing applications, William Jahns Jr. continued to operate W.H. Jahns Co., though now under the Jahns Racing Pistons banner, while reducing their vast catalog to include only the most profitable products. He simultaneously pushed forward with his racing piston development, becoming a leading of early high performance pistons that drove many cars of the day to win races and set records.
