2025 Season 2 - Races hourly at :45
Based on its real world counterpart that hearkens back to names like Jones, Foyt, and Andretti, the iRacing AMSOIL USAC National Championship pits top dirt track sim racers against one another in 410 Sprint Cars on some of the most challenging - and famous - dirt tracks in America.

Wings? We don't need no stinking' wings . . . just ask Parnelli, AJ and Mario—or for that matter, Jeff Gordon, Tony Stewart and Kyle Larson.
