The United States Auto Club (USAC) is one of the premier sanctioning bodies in motorsports. It sanctions several of the top series in the country, including the Silver Crown Series, the National Midget Series and the AMSOIL Sprint Car National Championship.
The latter series represents the largest group of open-wheeled, non-winged sprint cars in North America. These 1,400-lb. rockets combine the thrill of raw power with the action of sprint-car racing.
Some of racing’s most accomplished drivers have competed in USAC-sanctioned series, including Tony Stewart, Mario Andretti and Jeff Gordon. AMSOIL proudly supports USAC in its mission to bring grassroots racing to fans across the U.S.
