The 2008 LifeLock 400 was a Sprint Cup Series event held at Michigan International Speedway on June 15, 2008. Dale Earnhardt, Jr. snapped his seventy-six race winless streak with a dramatic victory, running out of gas as a caution ended the green-white-checkered. Junior coasted around to hold off Kasey Kahne. Kyle Busch finished 13th but actually expanded his points lead to 32 markers on Jeff Burton (15th).
