The series points leader, Biffle averaged 116.817 miles per hour around the 3/4-mile oval in his Ford Taurus on Friday to claim his fourth pole of the year and sixth career.
Biffle leads Jason Keller by 168 points with five races remaining.
"I never, ever would have dreamed that that time would have held up for the pole," said Biffle, who has four wins this season and 16 top-fives. "(The lap) might have been a little better, but I hit that curb and moved up four and five feet there. This is really a big boost to team confidence right now. We -- I should say I -- haven't been qualifying worth a dang.
Keller qualified 14th, also in a Ford.
"Qualifying up front is important, especially at a short track like this one," Biffle said. "I know that Keller qualified 14th. I'm keeping an eye on him."
Rookie Johnny Sauter will line up outside of Biffle in his Chevrolet Monte Carlo for his best qualification since taking the pole at the Aaron's 312 in Talladega in April.
