Harvick, who led a race-high 34 laps, finished fourth. The top five was completed by rookie Cole Custer.
As the race winner, Byron will start fourth in Sunday’s Daytona 500.
“There wasn’t any Chevy orders or anything like that,” Byron told FS1. “We just did a good job of working together. Kurt was a great pusher and great helper and I really had a lot of trust in him. I was really trying to go with one to go, but I had enough momentum out of the tri-oval, just watching old races that’s kind of where the momentum lines up. I didn’t know if I’d get that same momentum once everyone started pushing with one to go.”
The win is Byron’s first of any kind in the Cup Series. He joins Jeff Gordon and Chase Elliott, his predecessors in the No. 24, in having earned their first trip to victory lane in the Cup Series in a qualifying race.

The other “open” driver in the race, JJ Yeley, was eliminated in a crash with 18 laps to go.
