Kaulig Racing

Kaulig Racing is an American professional stock car racing team that currently competes in the NASCAR Xfinity Series. The team is owned by Matt Kaulig, an owner of team sponsor LeafFilter. It currently fields three Chevrolet Camaro SS teams: the No. 10 full-time for Ross Chastain, the No. 11 full-time for Justin Haley, and the No. 16 part-time for A. J. Allmendinger. The team has a technical alliance with Richard Childress Racing, and formerly operated out of the NTS Motorsports facility.

Car No. 10 history
In August 24, 2018, Kaulig Racing announced it will field a second entry for Austin Dillon at the September 8 Xfinity race at Indianapolis Motor Speedway.

On January 31, 2019, Kaulig Racing announced that Chastain would drive the No. 10 car for three races from Daytona, Chicagoland, and Texas. Dillon returned to the team for the Las Vegas spring race, while Elliott Sadler, who had retired from full-time racing after the 2018 season, drove the No. 10 at Richmond and the fall Vegas event. A. J. Allmendinger joined the team on March 21 for a five-race schedule at Daytona, Watkins Glen, Mid-Ohio, Road America, and the Charlotte Roval. At the 2019 Circle K Firecracker 250 at Daytona, Allmendinger finished third, but was disqualified after a post-race vacuum inspection revealed a discrepancy in his car's engine. Allmendinger was once again disqualified at the 2019 Zippo 200 at The Glen at Watkins Glen International on August 3, 2019 when his second-place finishing car was discovered to be too low on both rear corners during post-race inspection. He held off Tyler Reddick to win at the Charlotte Roval, scoring Kaulig Racing's second win of the season. Days prior to the Kansas race, the No. 10's hauler lost control on a North Carolina highway and crashed, leaving the hauler's drivers injured and the race car damaged.

The team will run full-time in 2020 with Alex Yontz as crew chief. On October 15, 2019, it was announced that the driver, competing full-time for the Xfinity Series championship, would be Ross Chastain.

Car No. 11 history
In June 2015, Blake Koch announced he and longtime sponsor LeafFilter Gutter Protection would re-sign with TriStar Motorsports for the 2016 season. However, in the 2015 offseason, LeafFilter owner Matt Kaulig decided to start his own team, Kaulig Racing. He brought along Koch, who he had sponsored the past two seasons, to pilot the No. 11 Chevy. Longtime NASCAR crew chief Chris Rice was hired as the team's general manager and crew chief. Kaulig Racing formed a technical alliance with Richard Childress Racing for the 2016 season. The team also used the owner's points of TriStar's former No. 8 team. In the team's debut, they finished 9th at Daytona after a strong showing, followed by a 20th-place finish at Atlanta the following week. For the team's third race Koch was running solidly in the top 15 before mechanical problems regulated him to a 26th-place finish six laps down. At Fontana, Koch finished 12th and on the lead lap, after running in the top 10 for much of the day. The team would later have several top-10 and top-15 runs, enough to get into the new Xfinity Chase, and also made to the 2nd round as well, but was unable to get to the final round, as he missed out by 7 points after finishing a strong 8th after running in or near the Top 5 all day. Blake finished 7th in the points, a Career best for Koch and Kaulig. On January 9, 2018, Kaulig Racing announced that they parted ways with Koch and had signed Camping World Truck Series driver Ryan Truex to drive the No. 11. Truex finished 7th in his team's debut.

After a mediocre 2018 season with only one top-five finish, the team announced on December 1, 2018, that Truex would be replaced by NASCAR Truck series title contender Justin Haley, who will compete for Sunoco Rookie of the Year honors in 2019.

Car No. 16 history
On June 27, 2019, Kaulig announced Ross Chastain would drive a third car, the No. 16, at the 2019 Circle K Firecracker 250 at Daytona. After a grueling race at Daytona, Chastain led 49 laps, won stage one, and later went on to score Kaulig Racing's first win.

Car No. 16 history
On January 10, 2020, Kaulig Racing announced they would make their NASCAR Cup Series debut at the Daytona 500, fielding the No. 16 for Justin Haley. The Fraternal Order of Eagles will sponsor Haley's entry. On February 8, Kaulig announced the team was looking to do more races in 2020. The next day, Haley made the field by posting the fastest qualifying speed of all the non-charter teams (190.018 mph; 31st overall).
