The help from his Hendrick Motorsports teammate enabled Johnson to nose out Bowyer by only 0.002 seconds -- the slimmest margin of victory in a Sprint Cup race since NASCAR began using electronic timing and scoring in the early 1990s.
Johnson, the five-time defending Sprint Cup champion, picked his 54th career Cup victory in the 500-mile race, which saw a record-tying 88 lead changes.
Pole-sitter Jeff Gordon came in third, Earnhardt finished fourth and defending Talladega champ Kevin Harvick claimed fifth -- all finishing within 0.145 seconds of each other.
