ESPN.com Friday that Harvick has signed a multi-year agreement to drive for Stewart-Haas Racing beginning with the 2014 season.
Harvick will remain at RCR, in the No. 29 Chevrolet for the 2013 campaign, sources said.
"I'm looking forward to finishing out this season on a strong note with RCR, and continuing to build our program going into the 2013 season with the ultimate goal of winning a championship," Harvick told ESPN.com Friday at Phoenix International Raceway, when approached about his future plans. "Anything beyond that, once I know what my future plans are set I'll let you know."
Under Stewart-Haas' current plan, sources said Harvick will drive a fourth SHR Chevrolet, teaming with Tony Stewart, Ryan Newman and Danica Patrick to form a four-car stable.
"Stewart-Haas Racing's driver lineup is all set for 2013, but if you're talking about 2014 and if Kevin Harvick is available, that's something the team would have to look at," said SHR team spokesman Mike Arning. "Any team in this garage would do the same. "From the moment Stewart-Haas Racing was formed, becoming a four-car team is something it's been striving for. They have the infrastructure to accommodate a fourth team, and if everything aligns properly, it's something they'll do. So, if a driver the caliber of Kevin Harvick is available, it's something they would pursue." (ESPN.com)
