Four NASCAR Chevy Teams Penalized After Vegas: Video

Four NASCAR Chevy teams from all three national series were penalized following the races at Las Vegas Motor Speedway from March 14^th through 16^th, 2025.

According to the latest penalty report from NASCAR.com, the most severe penalty was handed to the No. 8 NASCAR Chevy team of Kyle Busch. During the Cup Series race, Busch’s race car suffered a detached wheel, causing him to slam the wall, severely damaging the No. 8 Chevy. Busch’s team was penalized for violating safety guidelines outlined in the NASCAR Rule Book; specifically, Sections 8.8.10.4.A & C.

As a result, Busch has lost two over-the-wall crew members for the next two races. As such, he will compete without jackman Dylan Moser and rear-tire changer Shiloh Windsor starting with this weekend’s race at Homestead-Miami Speedway and continuing through the race at Martinsville Speedway on March 30^th. Busch’s NASCAR Chevy team wasn’t alone, either – the No. 19 Toyota TRD Camry of Chase Briscoe also suffered a loose wheel and has also had two crewmembers suspended.

In the Xfinity Series, two NASCAR Chevy teams were fined $5,000 for having one unfastened lug nut following the race at Las Vegas on March 15^th. The No. 11 Chevy of Josh Williams and the No. 88 Chevy of Connor Zilisch each had a loose lug found in postrace inspection, meaning their respective teams, Kaulig Racing and JR Motorsports, must pay up. Two Toyota teams – Joe Gibbs Racing and Sam Hunt Racing – were also penalized for the same infraction.

Finally, in the Truck Series, the No. 07 Chevy Silverado RST of Justin Haley was also found to have a loose lug in postrace inspection. His team, Spire Motorsports, was fined $2,500 for the infraction. Spire was the only team penalized following the Truck Series race.

As a reminder, the NASCAR Cup Series race cars feature single-lug wheels, while the Xfinity and Truck Series race cars still utilize the traditional five-lug hubs.
