Ron Hornaday Jr. won at Texas again.
Hornaday finished 0.958 seconds ahead of Busch, who led 87 laps in a backup truck salvaged this week from a hauler fire.
Benson finished third, nearly 9 seconds behind. But by passing two trucks in the final five laps to get that close, Benson retained the points lead in the close championship race. But his margin was trimmed from 31.
