The race was held on Sunday, September 29, 1991, before an audience of 43,500 in North Wilkesboro, North Carolina at the North Wilkesboro Speedway, a 0.625 miles (1.006 km) oval short track. The race took the scheduled 400 laps to complete. In the final laps of the race, taking advantage of a brake failure of the dominant driver of the day, Leo Jackson Motorsports driver Harry Gant, Richard Childress Racing driver Dale Earnhardt would mount a late-race charge to the lead, passing Gant with nine laps to go in the race to take the victory, breaking Gant's streak of four consecutive victories.

Qualifying was split into two rounds. The first round was held on Friday, September 27, at 3:00 PM EST. Each driver would have one lap to set a time. During the first round, the top 15 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 Saturday, September 28, at 12:00 PM EST. As with the first round, each driver would have one lap to set a time. For this specific race, positions 16-30 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 were given. If needed, a past champion who did not qualify on either time or provisionals could use a champion's provisional, adding one more spot to the field.

Harry Gant, driving for Leo Jackson Motorsports, won the pole, setting a time of 19.252 and an average speed of 116.871 mph (188.086 km/h) in the first round.

No drivers would fail to qualify.
