Fox Factory

Fox Factory Holding Corp. is an American company best known for their Fox Racing Shox brand of off-road racing suspension components.
In 1974, Bob Fox ran a small business distributing suspension components for motocross bikes with his brother Geoff. In 1977, the company split into what became Fox Racing (later Fox Head Inc.) under Geoff Fox, and Bob Fox's Fox Racing Shox parts production company, Fox Factory. A holding company, Fox Factory Holding, was established in 1978. Fox Factory produces suspension components for motorcycles, automobiles, all-terrain vehicles, side-by-sides, trophy trucks, snowmobiles, and mountain bikes.
In 2008 it was bought by a private equity firm, Compass Diversified Holdings. It went public in 2013.
