Jeff's career in NASCAR began in 1974 working as a tire changer for Walter Ballard.
Becoming one of the best jackmen in the business, Hammond served on all three of driver Winston Cup championship seasons.
Legendary driver Darrell Waltrip took over for Yarborough in 1981 and the Junior Johnson-owned team won yet another championship. At the encouragement of Waltrip, Johnson promoted Jeff to the crew chief position for the start of the 1982 season. And as the old saying goes, "The Rest Is History". The combination of owner Johnson, driver Waltrip and crew chief Hammond set the sport of NASCAR on its ear. Two more championships followed and 43 wins as a crew chief placed Hammond in the record books as one of NASCAR's all time great crew chiefs.
After his duties as crew chief, he spent much of his time as a NASCAR television analyst.
