Darian Grubb Named Interim Crew Chief at Kaulig Racing

Kaulig Racing has announced the immediate departure of Travis Mack as crew chief for the No. 16 Chevrolet Camaro ZL1 in the NASCAR Cup Series, with Darian Grubb stepping in as his replacement. The decision comes after a challenging season for Mack, who recorded one top-five and four top-ten finishes with a rotating cast of drivers, including Shane van Gisbergen. Mack, who joined Kaulig Racing from Trackhouse Racing, has had a total of one career win as a crew chief. Grubb, a seasoned crew chief with 24 Cup Series wins, will lead the team this weekend at Las Vegas Motor Speedway. The team expressed appreciation for Mack's commitment and stated that further announcements regarding the crew chief position would follow. This change is part of a broader trend of team adjustments in NASCAR, with other teams also making significant personnel changes recently.
