A brief red flag period ensued as Andretti's car was cleared before the race resumed on lap 372 with Edwards now leading Martin and Biffle as Kenseth tried to nurse his down on power machine home. The attempt was futile and on lap 373 it blew completely, ending Kenseth's day and bring out another caution period.
Edwards led the field to the green flag with 22 laps remaining but on lap 380 there was carnage as Kurt Busch, back up to fourth after receiving the Lucky Dog pass, blew a tyre and slammed the turn two wall in front of the majority of the pack. Busch's car cannoned into Sorenson who in turn slammed into the second Penske entry of Newman, blocking the track completely. In the ensuing chaos Truex Jr and Johnson both caught a piece of the action along with nearly a dozen others as the red flag waved again to clear up the mess. Busch was out on the spot while Truex Jr tried to soldier on with a severely damaged front end.
Truex Jr's rapidly disintegrating car was the cause of the 13th and final caution period on lap 392 and when the green flag finally waved for the final time Edwards had just four laps to hold off his remaining rivals. Despite a concerted effort from Biffle in the final laps Edwards held on to take the chequered flag and leap five places up the championship ladder after a day that completely shuffled the championship pecking order.
Biffle, Earnhardt Jr and Martin took second, third and fourth places with Kyle Busch the next Chase runner in fifth. Busch's Hendrick teammate Casey Mears was the only other lead lap finisher in sixth place while Burton managed to keep out of trouble to bring his ill-handling #31 Richard Childress Racing Chevrolet home in a surprise seventh, third best of the championship contenders.
McMurray recovered from his altercation with Juan Montoya to take eighth place while Tony Stewart salvaged ninth from a day that saw him run outside the top 20 most of the day. Montoya got the better of Jeff Gordon for tenth place while Bowyer finished 12th, his car hobbled following his scrape with Hamlin and Petty.
