Biffle traveled around the 1.5-mile Texas Motor Speedway at 193.736 mph for his third pole of the season and the ninth of his Sprint Cup career. He won on this track in 2005.
His lap time was .001 of a second faster than Roush Fenway Racing teammate David Ragan.
Matt Kenseth, another Roush driver, qualified third -- the best showing among the drivers who are part of the Sprint Cup chase for the championship.
