Dave Rogers, who has been working as crew chief for the organization's Mo. 20 Nationwide Series car for the past four years, will replace Steve Addington from the eighth race of the Chase onwards.
Addington, who has served as crew chief for the No. 18 team the previous five seasons, working beside Busch for the past two, will be reassigned to a position within JGR following this weekend's race at Talladega Superspeedway.
After an impressive run during the regular season last year where he scored nine wins, Busch failed to translate his success into the Chase, finishing only 10th in the championship.
This year he claimed four victories in the regular season, but just missed the play-off only for the second time since his rookie season in the Sprint Cup series.
"We evaluate all of our teams on an ongoing basis and believe this is a change that will make the 18 team stronger as we prepare for next season," said JGR president J.D. Gibbs.
"We think highly of Steve and the job he has done and we look forward to him remaining a part of the JGR family.
"Dave has proven himself a talented crew chief and we think he will work well with Kyle. We hope that by making the move following this weekend's race at Talladega they can use the final three weeks of this season to begin working on communication and setups for the 2010 season."
Rogers led JGR to their first Nationwide Series Owner's Championship in 2008 taking nine victories, six poles, 16 top-five finishes and 26 top-10 finishes, with drivers Kyle Busch, Tony Stewart, Joey Logano and Denny Hamlin.
This year the team has won five races under Rogers' leadership, all of them with Logano.
