Richard Childress Racing teammates Austin Dillon and Brendan Gaughan led the way in Friday’s second and final Xfinity Series practice at Dover International Speedway.
Gaughan appeared as if he would hold on to the fastest position until a late run by Dillon put him on the top spot.
Dillon’s speed was 154.261 mph, followed by Gaughan’s 154.195 mph burst. They were the only two drivers to exceed 154 mph.
Third-fastest was Daniel Suarez (153.932), followed by Darrell Wallace Jr. (153.702) and Matt Kenseth (153.185).
Next up for the Xfinity Series is Saturday qualifying at 11:15 am ET, with the Buckle Up 200 race later that afternoon at 2:30 pm ET.
