Qualifying
Qualifying was split into two rounds. The first round was held on Thursday, June 29, at 10:00 AM EST. Each driver would have one lap to set a time. During the first round, the top 20 drivers in the round would be guaranteed a starting spot in the race. If a driver was not able to guarantee a spot in the first round, they had the option to scrub their time from the first round and try and run a faster lap time in a second round qualifying run, held on Friday, June 30, at 11:00 AM EST. As with the first round, each driver would have one lap to set a time. For this specific race, positions 21-40 would be decided on time, and depending on who needed it, a select amount of positions were given to cars who had not otherwise qualified but were high enough in owner's points; up to two provisionals were given.

Mark Martin, driving for Roush Racing, would win the pole, setting a time of 46.909 and an average speed of 191.861 mph in the first round.

Five drivers would fail to qualify.
