The Stadium Super Trucks (SST), formerly known as Speed Energy Formula Off-Road, is an American short course off-road racing series created by off-road racer and former IndyCar and NASCAR driver Robby Gordon in 2013. Sanctioned by the United States Auto Club (USAC) in America with title sponsorship from Gordon's Speed Energy brand, the series utilizes identical off-road trucks that originally competed primarily in American football stadiums, but in 2014 began racing mostly on street circuits and road courses, often in conjunction with the IndyCar Series race schedules.
