Kurtis built some very low glass-fibre bodied two-seaters sports cars under his own name in Glendale, California between 1949 and 1955. Ford (US) running gear was used. About 36 cars had been made when the licence was sold to Madman Muntz who built the Muntz Jet. In 1954 and 1955, road versions of their Indianapolis racers were offered.
Kurtis-Kraft created over 550 ready-to-run midget cars, and 600 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."  Kurtis-Kraft created 120 Indianapolis 500 cars, including five winners. 
Frank Kurtis was the first non-driver inducted in the National Midget Auto Racing Hall of Fame (U.S.).
