Hello! I have a 2002 Ford Ranger Edge 4X4 and I'm looking for more power and better MPG. All I have changed are the tires, completely re-built and upgraded trans and computer, and put a Dynomax exhaust system in and looking at getting a Flowmaster 40 Series Delta. However, that is not enough. I was looking at getting and underdrive pulley but I don't know what to get and if it would even be worth it. Can you guys help?

Good luck.
i can only find the crank pulley.
apparently "underdog" used to have them but no more.
if you have any news, please reply

Not worth the price tag for the minuscule difference it will make. Besides, you'll want to have overdrive pulleys fitted to the alternator and power steering to keep their speed ratios the same. I had contemplated it long ago, but since they're all pretty much discontinued or way overpriced and troublesome to install, I dropped the idea.

It's a truck. And it's a 3.slow. It sucks gas and goes no where fast. It just is.
