It's Busch's third pole of the season, 13th of his career, but first ever for a restrictor plate race.
"I've not had many opportunities for me to win poles at restrictor plate races, so I've got to thank the team, all the guys at Joe Gibbs Racing that did such a good job building a slick race car," Busch said.
"It's a team effort coming to these places and having great race cars. I'm really excited to be starting up front, especially with my teammate Matt Kenseth on the front row with us."
Kenseth led 86 laps at Daytona in February and was out front with teammates Busch and Denny Hamlin right behind him when his engine failed. Two laps later, Busch was headed to the garage with his own race-ending failure.
"We were lined up 1-2-3 when I broke and Kyle broke shortly after that," said Kenseth. "Our plate stuff has been really fast this year. Qualifying doesn't always mean a lot at a superspeedway, but it's nice to start up front. Hopefully we can keep it up and stay in front of any potential trouble."
Clint Bowyer qualified third and Michael Waltrip Racing teammate Martin Truex Jr. was fifth as Toyota drivers took four of the first five spots. MWR team co-owner Michael Waltrip was seventh.
It was a strong showing for the Toyota drivers, who have battled various engine woes all season as manufacturer Toyota Racing Development has struggled to find the right balance of speed and durability.
