Ryan Preece drove the No. 18 to a third-place finish, while John Hunter Nemechek drove the No. 42 to a fourth-place result. Both cars are in the thick of an owners championship battle in the series.
The No. 52 Jimmy Means Racing Chevrolet driven by David Starr had one lug nut found to be unsecure.
In addition, the first and second-place cars of the No. 20 JGR Toyota (driven by race winner Christopher Bell) and the No. 22 Team Penske Ford (driven by Brad Keselowski) will be taken back to NASCAR’s R&D Center in Concord, North Carolina.
Last month, the No. 18 JGR team was assessed a L1-level penalty for failing post-race height measurements after Pocono that resulted in a one-race suspension for crew chief Eric Phillips, a $10,000 fine and a loss of 10 driver and owner points.
Any potential penalties will be announced next week by the sanctioning body.
