Clutch style fan?
I run that mopar performance clutch/fan package. It is a lot lighter then a Hayden clutch and the fan is light too. A lot less stress on the water pump shaft not to mention freeing up some power. And my car runs nice and cool too. Not cheap but well worth the money. For what you get its a pretty good deal. I have plenty of room between fan clutch and factory 3 core radiator. I'll never use anything else.
