In 2008, Bowyer continued to drive in the Cup and Nationwide Series full-time.
Bowyer dominated the late stages of the Daytona 500 but was spun out by Juan Pablo Montoya with 17 laps remaining.
On May 3, 2008, Bowyer earned his second Sprint Cup victory, winning the Crown Royal Presents the Dan Lowry 400 at Richmond International Speedway.
Bowyer led only two laps, going to the front after Dale Earnhardt Jr. and Kyle Busch got together with less than four laps remaining in the race.

On August 23, 2008, Bowyer was announced as the driver of the No.
33 Chevrolet Impala SS for RCR.
 Casey Mears from Hendrick Motorsports replaced Bowyer in the Jack Daniel's-sponsored car.
 This move was necessitated by a sponsor's request, as General Mills did not want Mears, who had been driving in the 2008 season for rival cereal maker Kellogg's, representing them, so Childress sponsors General Mills and Brown-Forman Corporation (parent company to Jack Daniel's) agreed to the swap so Bowyer, who drove for Brown-Forman, would drive for General Mills, and Mears could drive for Brown-Forman, as they had no problems with Mears representing the company.

On November 15, 2008, Bowyer won the NASCAR Nationwide Series Championship at Homestead-Miami Speedway with a narrow margin of victory over Carl Edwards of 21 points.
Edwards won the race with Bowyer finishing 5th.
