CONCORD, N.C. - Welcome to Hendrick Motorsports pit crew week!
Each day, we will attempt to shine some light on the brave men that leap over the pit wall every race, putting their bodies on the line to get your favorite drivers in and back out on the race track as quickly as possible.
Never before has the job of a NASCAR Cup Series crewman been more important, with track position more valuable than ever and the razor-thin margin between a good stop and a bad stop often deciding races.
