Richard "Slugger" Labbe will take over as crew chief for Dillon's No. 3 Chevrolet, replacing Gil Martin, who will move into a leadership role within RCR's research and development department. Labbe had worked in the department as well as served as crew chief for Dillon's younger brother, Ty, when he has run the No. 33 for Circle Sport Racing.
Austin Dillon, the 2013 Xfinity Series champion, is currently 23rd in the Cup series standings with just one top-10 finish.
Labbe's wins include the 2003 Daytona 500 and 2011 Brickyard 400, as part of 433 Cup starts to his credit.
