Addington worked with Kurt Busch's brother, Kyle, for the last two years at Joe Gibbs Racing, where they scored 12 victories together. However, the younger Busch failed to make this year's Chase for the Sprint Cup and Addington was removed from his position and replaced with Dave Rogers.
The 45-year-old will replace outgoing crew chief Pat Tryson, who worked with Kurt Busch for the past two and a half seasons, scoring five victories in that period. Tryson will join Michael Waltrip Racing to work with the team's new driver Martin Truex Jr.
"Steve Addington has a proven track record of success in NASCAR and we are excited to welcome him to Penske Racing," said Roger Penske. "By adding Steve to the winning team and working closely with Kurt, we believe we have the combination in place to compete for a championship as we head into the 2010 season."
This year Kurt Busch was among the title contenders for the Cup after missing out on the Chase in 2008. He finished fourth in the series' standings, his best since joining Penske in 2006 and best also among the non-Hendrick drivers who swept the top-three places in the championship.
"I am really looking forward to working with Penske Racing, Kurt Busch and the Dodge team," said Addington. "This a championship-caliber team with a great driver, and with the resources and experience at Penske Racing we have the opportunity to add to the team's success starting next season."
Despite the great success Penske has enjoyed in racing, the team is still looking for its maiden Cup title - its best result being runner-up in 1993 with Rusty Wallace.
