The Richard Petty Motorsports drivers are currently lying 24th (Allmendinger) and 29th (Sorensen) in the Cup standings, and Allmendinger says the switch should help the team to pool information and prepare for the 2010 season.
"I'm pumped about working with Mike [Shiplett] and his crew again, we went testing at Dover last week and worked really well together," he said.
"Sammy Johns and those guys did a heck of a job getting us ready to go racing right before the season and we had some really good runs. They are going to go over with Reed and we'll pool the information and improve our teams.
"We're here to win and get a jump on 2010. Mike and I want to work on everything that will make us a contender the rest of the season and hit the ground running in Daytona in February."
The Mike Shiplett-led crew will switch from Sorensen's #43 car to work on Allmendinger's #44, while crew chief Sam Johns will take his team the other way.
