There were no issues for race winner #42-Kyle Larson in post-race inspection at Dover International Speedway. His car passed and he is officially the winner.
Pole winner #11-Denny Hamlin did have one loose lug nut. That will be a $10,000 fine.
#4-Kevin Harvick’s car will be taken back to the NASCAR R& D Center for NASCAR to examine (just as a reference, not for potential penalties).
