What kind of jack does Nascar use?

Answer 1

The only rule is the jack has to be strong enough to lift a race car and operated by human power - you can't use one that runs on air, and such jacks exist. The jacks they use are called "race jacks." They're made from aluminum and will lift the car high enough to remove the wheel with one pump of the handle. The handle can be as long as you want, but a rule says you can't exchange a jack during a pit stop unless the old one broke; this keeps guys from buying jacks with handles 30 feet long for that extra leverage because you wouldn't be able to use it on the side next to the pit wall.
