Two practice sessions were held in preparation for the race; both on Friday. The first session lasted 90 minutes long, while the second was 60 minutes long.[9] Reutimann was quickest with a time of 29.486 seconds in the first session, 0.028 seconds faster than Clint Bowyer.[10] Mark Martin was just off Bowyer's pace, followed by Kyle Busch, Trevor Bayne, and Newman. Some Chase for the Sprint Cup participants were not scored high in the first practice, such as Johnson and Hamlin, who were 36th and 40th in the session.[10]

In the second and final practice, Brian Vickers was quickest with a time of 29.304 seconds. Kasey Kahne followed in second, ahead of Kenseth and Paul Menard. Harvick was fifth quickest, with a time of 29.455 seconds. Gordon, Greg Biffle, Johnson, David Stremme, and Edwards rounded out the first ten positions. Kyle Busch, who was third in the first session, could only manage forty-fourth.[11]

Forty-seven cars were entered for qualifying, but only forty-three could race because of NASCAR's qualifying procedure.[12] Kenseth clinched his sixth pole position in the Sprint Cup Series, with a time of 29.469 seconds.[13] He was joined on the front row of the grid by Menard.[13] Kurt Busch qualified third, Newman took fourth, and Edwards started fifth.[13] Johnson, one of the drivers in the Chase for the Sprint Cup, qualified twelfth, while Harvick was scored thirtieth.[13] The four drivers that failed to qualify for the race were Travis Kvapil, David Starr, Stephen Leicht and Mike Skinner (T.J. Bell was gonna enter the race but withdrew).[13]

Once qualifying concluded Kenseth said, "I think starting up front is nice, having a good pit stall. Hopefully, you can get a good start and get a bonus point for leading a lap and try to keep up with the track a little better. We've been qualifying a lot better, if you throw Richmond out, but we've been slipping a little at the end of the race. I'm really happy to be on the pole, but it's just a starting position, and we've got to work really hard on the race, keeping up with our adjustments and that type of thing."[3]

The race, the twenty-seventh of the season, was scheduled to begin at 2:00 p.m. EDT on September 18, but wet track conditions postponed the race to September 19, 2011 at 12:00 p.m. EDT.[14] The race was televised live in the United States on ESPN.[1]
