Johnston served as crew chief for Martin Truex Jr.'s No. 56 team at Michael Waltrip Racing during the 2012 and '13 Sprint Cup seasons. He is replacing Steve Addington, who has left SHR. Addington had guided Stewart's efforts since the start of the '12 season.

Greg Zipadelli was named vice president of competition at SHR. Zipadelli will manage all four of its Sprint Cup teams. Matt Borland was elevated to vice president of engineering. Borland had been the crew chief for SHR's No. 39 car, which was driven by Ryan Newman.

SHR promoted Daniel Knost from race engineer on the No. 39 to crew chief for the team's new No. 41 car, which will be driven by Kurt Busch.

Roush Fenway made numerous crew chief swaps within its organization. Crew chief Mike Kelley will be reunited with driver Ricky Stenhouse Jr. at the No. 17 team in Sprint Cup after the two won back-to-back Nationwide championships from 2011-12.
