Piano Bars

Piano bars may be necessary if the car is too low to get the jack underneath.

­When it comes to NASCAR, a piano bar isn't something Billy Joel used to play in. Sometimes a car will come into the pit with severe body damage or even flat tires, making it ride low to the ground. In some cases, it's too low for the jack man to get the jack underneath to lift it up. That's where piano bars come in.

Piano bars are essentially long, strong bars that the crew can slip under the car. They use the bars like a lever to lift the car off the ground -- at least far enough to get the jack underneath. The piano bars are a basic, almost failsafe tool because there are no moving parts to break and they use the basic principle of leverage to overcome the weight of the car. All the crew needs to do is add is a little bit of ­muscle and they're good to go.

­In racing, you've got to have gas to go -- NASCAR is no exception. But without making a stop at the local fuel pumps, how does a NASCAR car go the distance? Read on to find out.
