Byron, who was 11th fastest in Saturday practice, completed a 110.359 mph lap on the 14-turn, 4-mile road course in Elkhart Lake, Wis., To earn his sixth career Cup pole. .
“We had a little trouble getting out of the truck (Saturday), but we had some good changes in mind,” Byron told CNBC. “It was fast in the race the last round… We struggled this year on the road circuits and we kind of went back to a basic setup and got everything in place today. “
Hendrick Motorsports teammate Kyle Larson, who won the last Cup road race in Sonoma, will start alongside Byron in the front row.
Behind them in row 2 will be Xfinity regulars AJ Allmendinger and Tyler Reddick.
Reddick had a potential lap to take pole in the dying moments of qualifying before pulling away at Turn 12. He then sped into the final turn, Turn 14, to complete his lap.
Defending Xfinity champion Austin Cindric will start fifth. Denny Hamlin will start sixth.
The first round of qualifying was marked by two red flags for Kyle Tilley and Bubba Wallace stopping on track in separate cases.
Defending Cup champion Chase Elliott, winner of five of the last seven road races in the Cup, has seen a potential flyer canceled every time.
After the green returned with less than two minutes left in the round, it did not return to the start / finish line in time to begin a proper round. As a result, he will start 34th.
“Yesterday at practice we had a few mishaps and NASCAR added a little bit of time, so our only hope was that they would add a little bit of time to let the pit lane guys come back,” Elliott told NBCSN.
“It’s a bet, and I don’t expect them to do that. But you also need to be prepared in this situation. Just one of those situations where I don’t know what you’re really doing. Just keep going on the road and hope the race is better and our car is where it needs to be. “
Six cars will go to the rear for the start of Sunday’s race.
Kyle Busch and Ryan Preece were already going there in rescue cars after incidents during practice on Saturday. Wallace (drivetrain), Tilley (tuning not approved), Justin Haley (motor) and Josh Bilicki (tuning not approved) are now joining them.
