"With the same courage, passion and vigor that he raced with each night, he fought valiantly to the end", Jason Johnson Racing said in a statement.
It was painfully reminiscent of what the racing community went through in August 2016 when national star Bryan Clauson suffered life-threatening injuries in a midget race in Kansas and died the next day. "My heart goes out to Jason, his family, his friends, his competitors and his fans".
In 2013, Jason Leffler died following a crash at a New Jersey sprint vehicle race. Stewart, Larson and current NASCAR driver Kasey Kahne own Outlaws race teams.
Kingsburg's Cory Eliason, racing for Easton-based Roth Motorsports, was eighth in the Outlaws race in Wisconsin.
"Everyone at SLS Promotions offers our deepest, most honest thoughts, prayers and condolences to Bobbi Johnson (Jason's wife), Jaxx Johnson (the couple's son) and the entire Johnson family and JJR Racing team".
