Alex Yontz

Alexander Kenneth Yontz (born July 13, 1986) is an American professional stock car racing crew chief and former driver who works for Kaulig Racing as the crew chief of their No. 10 Ram 1500 driven by Corey LaJoie. He also previously crew chiefed Kaulig's No. 16 car in the NASCAR Xfinity Series, driven by Christian Eckes, No. 11 car in the Xfinity Series, driven by Justin Haley and Daniel Hemric, and their No. 10 car driven by multiple drivers, as well as Kaulig's No. 25 truck from February to July 2026.

Racing career Driving career

Crew chiefing career Yontz began crew chiefing in the Xfinity Series midway through 2019 after the unexpected death of Nick Harrison, the crew chief of Kaulig Racing's No. 11 car driven by Justin Haley. He continued in that role in 2020 and 2021. When Haley moved up to Kaulig's new No. 31 car in the Cup Series in 2022, Yontz did not move up with him and he continued to crew chief the No. 11 car in the Xfinity Series, now driven by Daniel Hemric.

On September 9, 2022, it was announced that Yontz would be switching cars, moving from the No. 11 of Hemric to the No. 10 of Landon Cassill starting with the race at Kansas the next day. Both the No. 10 and No. 11 cars had struggled during the season compared to Kaulig's No. 16 car driven by A. J. Allmendinger and were close to the bottom of the playoff grid and in danger of falling out. (Even after the crew chief swap, Cassill's No. 10 car ended up missing the playoffs.) Jason Trinchere, who was the crew chief of Cassill's No. 10 car, switched cars with Yontz and became the crew chief for Hemric's No. 11 car. Yontz continued as crew chief of the No. 10 car in 2023 when it was driven by multiple drivers.

On December 19, 2023, Kaulig announced that Yontz would move from their No. 10 car to their No. 16 car in 2024 where he would crew chief A. J. Allmendinger, who returned to the Xfinity Series full-time after 1 year of running full-time in the Cup Series for the team. On December 19, 2024, the team confirmed that Yontz would return to the No. 16 car in 2025 with new driver Christian Eckes as Allmendinger moved back up to the Cup Series full-time for Kaulig.

In 2026, Kaulig closed down their Xfinity Series (now O'Reilly Auto Parts Series) program while they started a NASCAR Craftsman Truck Series program with Ram Trucks as the manufacturer, who re-entered NASCAR after having left after the 2012 season. Yontz would move to crew chief one of the new Kaulig trucks, the No. 25, driven by a rotation of noteworthy NASCAR stars as part of the "Free Agent" program, starting with Tony Stewart at Daytona. On July 9, 2026, Kaulig Racing announced that Yontz would switch trucks with Dan Stillman starting at Lime Rock Park. Yontz would move to their No. 10 truck driven by Corey LaJoie and Stillman would now crew chief the No. 25.
