All of the leaders stayed out on track, allowing Martin to remain the leader on the restart. On lap 6, McMurray passed Earnhardt to claim the second position. One lap later, the second caution was prompted after Paul Menard spun sideways at turn two, collecting Ragan, Michael Waltrip, Max Papis, and Bobby Labonte.^[19][20] During the caution, most of the leaders elected to make pit stops. Martin maintained his lead on the restart, with Earnhardt in second, and Keselowski third. On the 12th lap, Earnhardt moved into the first position after passing his teammate Martin at turn four.

They lasted until the 62nd lap, and Johnson took the lead after their conclusion with Keselowski second, and Stewart in third. Seven laps later, the third caution was necessitated for Reed Sorenson who hit the turn two wall. During the caution, several drivers (including Johnson), elected to make pit stops for tires.

Biffle got ahead of Johnson as his pit stop was faster than his and led the field at the lap 131 restart.^[1][21] On the next lap, Johnson re-passed Biffle around the outside in the third turn to reclaim the lead.^[19][21] After starting 22nd, Hamlin moved into sixth unnoticed by lap 132. Nine laps later, Montoya overtook Biffle to take the second position, as Johnson increased his lead over Biffle to 4.4 seconds. Elliott Sadler pirouetted through 360 degrees in turn two, but avoided contact with the wall and passing vehicles on lap 147, activating the fifth caution. Under caution, all of the leaders (including Johnson) went to pit road for tires and car adjustments.^[19] Biffle regained the lead, and held the position at the lap 152 restart.^[1] Hamlin overtook Martin for second place soon after.^[21] Three laps later, Gordon passed Martin for fourth, and Marcos Ambrose lost the tenth position to Kahne.

Hamlin got ahead of Kahne to claim third place three laps later. Between laps 221 and 223, Johnson, Gordon and Montoya battled for third but neither driver could advance their positions. On the 230th lap, Martin passed Montoya for seventh. The sixth (and final) caution came out as Earnhardt's engine failed, and oil from his car laid on the track. He brought his into the garage to retire from the race. During the caution, the leaders (including Biffle), elected to make pit stops for fuel and tires.^[19] Biffle requested four tires be installed on his car after he overruled his crew chief Greg Erwin's decision to have two tires fitted. Stewart, meanwhile, had two tires installed, and exited pit road as the new race leader on lap 238.^[23]

Stewart maintained the lead at the lap 242 restart,^[1] followed by Kahne, Johnson, Biffle and Hamlin. Biffle then passed Kahne and Johnson to move into second, as Stewart opened up a healthy advantage. In the meantime, Johnson fell to sixth as he struggled with his two new tires. Five laps later, Hamlin went to the track's apron to pass Kahne and Montoya for the fourth position. Johnson was passed by his teammate Martin for eighth on the 248th lap. Gordon caught Biffle and got ahead of him for second six laps later.^[19] Although Gordon reduced Stewart's lead, it was not enough for him to challenge the latter, as Stewart responded to Gordon's pace,^[19] and took his second win at Kansas Speedway, his fourth of the season, and the 37th of his career.^[24] Gordon finished second, Biffle came third, Montoya took fourth and Hamlin fifth. Kahne, Martin, Reuitmann, Johnson and Edwards completed the top ten finishers.^[24] The race had a track-record 26 lead changes amongst 14 different drivers.^[1][20] Biffle led six times for a total of 113 laps, more than any other driver. Stewart led five times for a total of 37 laps.^[1]

Stewart appeared in Victory Lane to celebrate his fourth victory of the season in front of a crowd of 100,000 people;^[20] the win earned him $332,498.^[1] He credited his crew chief Darian Grubb for a strategy that allowed him to take the lead, "The guys that took four could just never gain the track position back. We had a really good car on two tyres. Darian and these guys on the pit crew, they are the ones that got us the win. They got us track position and I was able to pick which line I wanted on the restart and that won us the race."^[25] Gordon explained that his car became harder to handle the closer he got to Stewart, "As long as he didn't make any big mistakes, I wasn't going to catch him.", and also admitted to have selected the wrong tire strategy, "I know what I did was wrong. I know I made a mistake. But we're sure excited to be running good again, especially going to some tracks we like, like California."^[23] Third-placed Johnson said of his situation in the championship and the loss of a victory, "I hate losing points, I felt like we had a shot to win the race, it's just way too early, for myself, even to start worrying about [the Chase standings.] It's only three races in."^[23]

Grubb commented on Stewart's victory, "Tony was able to get out there in clean air and was able to take off. The other guys who took two [tyres] ended up 7th and 9th. So Tony was able to get that clean air and just take off. He did an awesome job today; the entire pit crew and everybody did an awesome job all day long."^[25] Although he finished seventh, Martin said he was pleased with the result as he was able to keep the points lead, "This is the first time we missed it that much in a while. There have been times when I was off this much and finish 25th. But our team fought for everything we got today."^[26] However, he was not celebratory as he was unsure whether he could keep his advantage in the next few races, "What is there, seven more to go? I don't think we should be getting all hyped up about the tally right now, you know? We've got a lot of racing to go."^[27]

After the race, Johnson's and Martin's cars were transported to NASCAR's Research and Development Center in Concord, North Carolina for a further precautionary inspection because those two vehicles had been close to exceeding to the organizing body's measurement tolerance limits at the previous week's race at Dover International Speedway.^[28] After personnel from Hendrick Motorsports were allowed to observe the potential issues to the two cars, both passed their inspections.^[29] The race results left Martin with the Drivers' Championship lead with 5,551 points. Martin's teammate Johnson was 18 points behind in second, and Montoya kept third with 5,500 points. Stewart's win allowed him to move past Kurt Busch and advance into the fourth position. Hamlin, Gordon, Biffle, Newman, Edwards, Kahne, and Vickers completed the top twelve drivers in the points standings.^[30] Because of Stewart's victory, Chevrolet won its seventh Manufacturers' Championship in a row, and its 33rd in NASCAR Cup Series competition.^[31] Toyota maintained second with 167 points. Ford moved four points clear of Dodge in the battle for third with seven races left in the season.^[8] The race attracted 5.25 million television viewers;^[4] it took two hours, 55 minutes, and 13 seconds to complete, and the margin of victory was 0.894 seconds.^[1]
