Kurtis Kraft was an American designer and builder of race cars. The company built midget cars, quartermidgets, sports cars, sprint cars, Bonneville cars, and USAC Championship cars. It was founded by Frank Kurtis when he built his own midget car chassis in the late 1930s.
Kurtis built some very low fiberglass bodied two-seaters sports cars under his own name in Glendale, California between 1949 and 1955. Ford (US) running gear was used. About 36 Kurtis Sport Cars had been made when the licence was sold to Earl "Madman" Muntz who built the Muntz Jet. In 1954 and 1955, road versions of their Indianapolis racers were offered.
Kurtis Kraft created 387 midget cars, some ready to race and some without engines or otherwise incomplete. Parts for several dozen were sold also, possibly as "kits." The Kurtis Kraft chassis midget car featured a smaller version of the Offenhauser motor. The National Midget Auto Racing Hall of Fame describes the combination as "virtually unbeatable for over twenty years."
