Kyle Busch and Kyle Larson hit each other on the final lap and Busch emerged with his fifth Monster Energy NASCAR Cup Series win of the season.
Busch appeared headed to the win but lapped traffic allowed Larson to close on the No. 18’s rear bumper on the final lap.
Larson nudged Busch to take the lead and Busch returned the favor and spun Larson, hitting the wall in the process but had enough momentum to claim the win in Sunday.
"He tried to pull a slide job and didn't get it all the way," Busch said of Larson's move on the last lap. "He wasn't close enough to get it all the way.
"When he got into us, I got into the wall and killed my right-side and it was on after that. It was who can get back to the checkered flag first. This (car) was horrible today but we made the most of it. We adjusted the entire race to be where we need to be at the end.
"We got some clean air finally - my pit crew did a great job helping me there to get this race car out front."
Kevin Harvick finished third, Martin Truex Jr. was fourth and Clint Bowyer completed the top-five.
Rounding out the Top 10 were Erik Jones, Denny Hamlin, Joey Logano, Brad Keselowski and Alex Bowman.
The win is Busch’s fifth of the season and 48th of his career.
Following pit stops during the break between Stages 2 and 3, Harvick was the first off pit road and continued to hold the lead when Stage 3 went green on Lap 168. He was followed by Kurt Busch and Truex.
Busch quickly powered past Harvick on the restart with Larson moving into second.
On Lap 171, Larson got around Busch to take the lead for the first time in the race.
Two laps later, Harvick moved back up into second and began working on Larson for the lead.
Harvick reclaimed the lead on Lap 176.
Hamlin spun off Turn 2 on Lap 177 to bring out a caution. All of the lead-lap cars elected to pit and Logano came off pit road first thanks to a two-tire pit stop. Keselowski and Aric Almirola stayed out.
Daniel Suarez was penalized for speeding on pit road during the stops.
On the restart on Lap 181, it was Keselowski, Almirola, Logano, Harvick and Larson.
On Lap 185, Harvick moved up into the second position with Logano dropping to third.
On the next lap, Harvick got around Keselowski – who had stayed out under the previous caution – to retake the lead.
With 70 laps remaining in the race, Harvick moved out to a more than three second lead over Kyle Busch as a severe thunderstorm watch was issued for the area around the speedway.
Corey LaJoie hit the wall on Lap 208 to bring out another caution. All of the lead-lap cars elected to pit for tires and fuel. Paul Menard and Trevor Bayne were both penalized for speeding on pit road.
