Kurtis Kraft was an American company that designed and constructed various types of race cars, including midget cars, quarter midgets, sprint cars, sports cars, Bonneville cars, and USAC Championship cars. The company was founded by Frank Kurtis, who built his first midget car chassis in the late 1930s. Kurtis Kraft became one of the most successful and innovative race car builders in the United States during the 1940s and 1950s, winning numerous races and championships. The company's cars were renowned for their light weight, excellent handling, and advanced engineering, and were driven by many of the top drivers of the era. Kurtis Kraft continued to build race cars into the 1960s, but eventually ceased operations due to changing trends in the racing industry. Today, Kurtis Kraft cars are highly sought after by collectors and vintage racing enthusiasts for their historic significance and exceptional performance.
