The 2004 Carolina Dodge Dealers 400 was a Nextel Cup (now Sprint Cup) event held at Darlington Raceway on March 21, 2004. Jimmie Johnson held off a charging Bobby Labonte in the thrilling few final laps to record his first victory of the year, holding off Labonte by just over a carlength. Points leader Matt Kenseth struggled to 31st and watched his points lead shrink to twenty-one points on Dale Earnhardt, Jr (10th) as a result.
