where can I get an under drive pulley? What does it do?

www.stuffforyourranger.com is a good place to look. I know they sell them there. And they change the circumferences of the pullies (depends on what you get, theres many options) Say you just get the crank pulley, it will be bigger and make the engine accessories turn less which is supposed free up robbed power. I didn't explain it too well...check out this thread (I know 3.0L but the concepts are the same) http://www.therangerstation.com/forums/showthread.php?t=56572
