What Are the Positions in a NASCAR Pit Crew?

A NASCAR pit crew has six positions, including rear and front tire carriers, rear and front tire changers, jack man, and gas man. NASCAR occasionally allows an extra person who must stay behind the wall but can lean over to clean the windshield or assist the driver.

A NASCAR pit crew also has a support team. These people assist the wall crew by rolling tires, retrieving air hoses, finding wrenches and handing them fuel. Support team members must stay behind the wall for all pit stops. A NASCAR official watches all pit stops for violations. The crew chief is responsibility for the race strategy and pit stop setup.
