Kahne's first win of the season earned him a spot in the Chase for the Sprint cup. Kenseth also qualified for the Chase on points.
Denny Hamlin was third, followed by Jimmie Johnson, Carl Edwards and Danica Patrick.
Meanwhile, Tony Stewart's much-anticipated return to racing ended a little more than halfway through the race.
Stewart hit the wall for the second time after his right front tire blew out on Lap 172, ending his night with a 41st-place finish.
