NASCAR has penalized the crew chiefs of two Cup teams for unsecured lug nut violations incurred in Monday’s Gander RV 400 at Dover International Speedway.
Billy Scott, crew chief for the No. 41 Stewart-Haas Racing Ford driven by Daniel Suarez, and Chad Johnston, crew chief for the No. 42 Chip Ganassi Racing Chevrolet driven by Kyle Larson, were fined $10,000 apiece for unsecured lug nuts on their respective cars.
Larson finished third, his best showing of the season, while Suarez finished 11th.
There were no other violations in the Cup, Xfinity or Truck Series.
