Rick Crawford won the pole during morning qualifying in a light drizzle, but the rain increased in intensity as the 2 p.m. starting time approached. It was called an hour later.
Crawford won the pole with a lap at 94.737 mph in his Ford. He'll start on the inside of the front row with Shane Sieg to his outside. Sieg's lap was at 94.326 mph in his Toyota.
The top five also includes Johnny Benson, Ron Hornaday Jr. and Colin Braun.
The pole is the sixth for Crawford in 301 career truck series starts, and he was not concerned with the prospect of seeing it postponed as the rain fell throughout the day.
"I don't mind not racing if nobody else gets to," he said.
The 0.526-mile oval does not have lights and can't support night racing. The Goody's 500 Sprint Cup race is scheduled for Sunday at the track.
