Chad Knaus was adamant Friday at Atlanta Motor Speedway that teams are not being given single-sourced supplied parts with correct specifications and Hendrick Motorsports only made the modifications to the hood louvers that resulted in penalties for the team in order to make them fit.

“We made sure our parts fit the hood, and the hood closed and did all the stuff that it needed to do,” said Knaus, Hendrick Motorsports’ vice president of competition (pictured at left, above, with team owner Rick Hendrick).

NASCAR confiscated the hood louvers from all four cars the Friday of Phoenix weekend. Although issues were found beforehand, all four teams were allowed to participate in practice before the louvers were taken.

The teams were penalized earlier this week. In addition to $100,000 fines to all four crew chiefs and suspensions, the Nos. 5, 24, and 48 teams were docked 100 driver points, and all four teams were docked 100 owner points. There was also the loss of 10 playoff points.

“When we started to get parts at the beginning of the 2023 season, we didn’t have the parts we thought we were going to have,” Knaus said. “Through a tremendous amount of back and forth with NASCAR and the OEM and the teams, there’s been conversations about whether we can clean up the parts, not clean up the parts and it’s changed, quite honestly, every couple of weeks. So, it’s been challenging for us to navigate, and we’re going to have to see what happens when we get through the appeal.”
