The layout of Michigan International Speedway, the venue where the race was held.

The race was held at Michigan International Speedway, a two-mile (3.2 km) moderate-banked D-shaped speedway located in Brooklyn, Michigan. The track is used primarily for NASCAR events. It is known as a "sister track" to Texas World Speedway as MIS's oval design was a direct basis of TWS, with moderate modifications to the banking in the corners, and was used as the basis of Auto Club Speedway. The track is owned by International Speedway Corporation. Michigan International Speedway is recognized as one of motorsports' premier facilities because of its wide racing surface and high banking (by open-wheel standards; the 18-degree banking is modest by stock car standards).

Qualifying was split into two rounds. The first round was held on Saturday, June 27, at 11:30 AM EST. Each driver had one lap to set a time. During the first round, the top 20 drivers in the round were 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 Saturday, at 2:00 PM EST. As with the first round, each driver had one lap to set a time. For this specific race, positions 21-40 were 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 were given.

Rusty Wallace, driving for Blue Max Racing, managed to win the pole, setting a time of 42.168 and an average speed of 170.746 miles per hour (274.789 km/h) in the first round.

12 drivers failed to qualify.
