Former Evernham driver Scott Riggs took over the No. 66 in 2008 with State Water Heaters as the sponsor, coming over from Morgan–McClure Motorsports. Hunt Brothers Pizza and Haas Automation also appeared on the car. Riggs struggled early on, but his performance picked up following the announcement of Tony Stewart as the new co-owner of the team in mid-summer. Riggs finished the season in the top 35, but was released in favor of Ryan Newman who had just departed from Penske Racing. With Newman driving, the car changed numbers to No. 39, which was Newman's midget car number. The U.S. Army signed on to sponsor the car alongside State Water Heaters and Haas Automation, but Hunt Brothers moved to JR Motorsports in the Nationwide Series.
