Dillon paced the 38 cars that took to the track with a speed of 180.294 mph. Hemric was close behind in second place at 180.078 mph.
Of note, several drivers and teams took part in drafting, which is typically unusual at a track like LVMS. But with the new aero package in use this weekend, speeds were enhanced for several cars by utilizing drafting.
