On July 29, 2019, following a string of disappointing finishes during the 2019 season, Hendrick Motorsports announced that Daniels would replace Kevin Meendering as the crew chief of the No. 48.[1][3][4]
On October 28, 2020, Daniels was announced to become the crew chief for No. 5 of Kyle Larson. The 5 car would replace the No. 48 in 2021.[5]
On March 7, 2021, Daniels earned his first win as a crew chief in the 2021 Pennzoil 400. He won his first championship as a crew chief in 2021 at Phoenix.
On June 14, 2022, Daniels was suspended for four races due to a tire and wheel loss during the Sonoma race.[6]
On March 15, 2023, NASCAR suspended all four Hendrick Motorsports crew chiefs (Daniels, Alan Gustafson, Rudy Fugle and Blake Harris) as well as Kaulig Racing No. 31 car crew chief Trent Owens for four races after it was discovered during practice for the race at Phoenix in March that the hood louvers on all five cars were illegally modified. As a result, each team received an L2 penalty (a loss of 100 driver and owner points as well as the four-race crew chief suspension).
