Texas Motor Speedway is a speedway located in the northernmost portion of the U.S. city of Fort Worth, Texas – the portion located in Denton County, Texas. The track measures 1.5 miles (2.4 km) around and is banked 24 degrees in the turns, and is of the oval design, where the front straightaway juts outward slightly. The track layout is similar to Atlanta Motor Speedway and Charlotte Motor Speedway (formerly Lowe's Motor Speedway). The track is owned by Speedway Motorsports, Inc., the same company that owns Atlanta and Charlotte Motor Speedway, as well as the short-track Bristol Motor Speedway.

Initially, two practice sessions were scheduled for the event- however, second practice would be rained out, meaning that second practice was canceled.^[2]

Qualifying would take place on Friday, June 8 on 4:45 CST. Since Texas Motor Speedway is at least a 1.5 miles (2.4 km) racetrack, the qualifying system was a single car, single lap, two round system where in the first round, everyone would set a time to determine positions 13–32. Then, the fastest 12 qualifiers would move on to the second round to determine positions 1–12.^[3]
