Superior air parts started as a manufacturer of valve guides in 1967. The company branched out into FAA/PMA approved parts for general aviation aircraft. The company manufactures replacement parts for Lycoming and Continentalaircraft engines. The cylinder assemblies use newer cylinder head alloys and fully hardened cylinder liners. Most of the company's production is outsourced, with Superior ensuring that the parts meet their engineering and testing standards. In 2008, Superior Air Parts parent company Thielert declared bankruptcy. Superior was sold to Superior Aviation Beijing (Qingdao Brantly Investment Group and Beijing Suyoupeirui Company).
At AirVenture 2012 CEO Tim Archer announced that the company was recovering from its bankruptcy and that the Chinese investment had been critical in that turn around. The company was at that time able to ship almost 90% of parts in its catalog and was training Chinese technicians in Vantage engine production for the Asian market.
