Kaulig Racing

Cup Series

During the first round of the inaugural NASCAR In-Season Challenge at Atlanta, Dillon started as the #32 seed and finished 8th, defeating #1 seed Denny Hamlin. He made it to the final round at the Brickyard 400 against Ty Gibbs, but Gibbs defeated Dillon to win the US$1 million. Kaulig Racing also fields a third car on a part-time basis. Smith made his official Cup debut at Richmond, finishing seventeenth. Dirt racer Jonathan Davenport drove the entry in his Cup Series debut at the Food City Dirt Race, finishing 36th.

Xfinity Series

Kaulig Racing first fielded an Xfinity Series car in 2016. In 2018, Austin Dillon drove the No. 10 entry once, at Indianapolis Motor Speedway, and placed eighth. The following year, on January 31, Kaulig confirmed Ross Chastain would pilot the No. 10 at Daytona, Chicagoland, and Texas. Dillon came back for the spring race in Las Vegas, and Elliott Sadler, who had retired from full-time racing after 2018, took the wheel at Richmond and the fall Vegas event.

A. J. Allmendinger joined on March 21 for a five-race stretch covering Daytona, Watkins Glen, Mid-Ohio, Road America, and the Charlotte Roval. He was disqualified again at Watkins Glen after his second-place car measured too low on both rear corners. Allmendinger then beat Tyler Reddick to win at the Charlotte Roval, giving Kaulig its second victory of the season. Days before the Kansas race, the No. 10 hauler crashed on a North Carolina highway, leaving its drivers hurt and the race car wrecked.

In 2020, the team ran a full schedule with Chastain and crew chief Alex Yontz. Chastain never won a race and missed the Daytona field, but he notched five second-place finishes and 27 top-tens—the most of any driver that year—to end seventh in points. He left after 2020 to take over Matt Kenseth’s No. 42 Cup car at Chip Ganassi Racing, and Jeb Burton stepped in for 2021.

Craftsman Truck Series

The team would field up to five trucks, including the No. 10, marking the first factory-backed Ram entry in NASCAR since 2012. The No. 10 was initially used as a show car. In November, Ram Trucks launched a "Free Agent Program" for the No. 25 truck, where drivers could win a prize based on individual performance without competing for the championship. Kaulig confirmed its truck numbers in December. A. J. Allmendinger substituted for Dye at Darlington. Dye was released later that month, and Corey LaJoie took over the No. 10 for the remainder of the season. Brenden Queen drove the No. 12. Mini Tyrrell won the "Race for the Seat" competition, produced with Dana White's Thrill Sports Productions and aired on Fox, earning a full-time ride in the No. 14. Justin Haley drove the No. 16.
