Damn that's a lot more. I'll trade you my 3.0 for your 4.0 and then you'll only have to pay $115 for pullies. Haha jk!

 

who has the best price on pullies?

 

here's my little install guides. Removing the fan and shroud gives more room on the 3.0, but the fan removal is difficult for some people:

you won't regret it when they come in the mail. I picked up the package and was like holy crap these are light!!! And they are SO pretty. Great mod for the money. I noticed 2 more mpg on average. i could go like 20-30 extra miles a tank

 

MPG is what I was curious about. Did you change more than the crank pulley? Any problem with idle or charging? How difficult to install? I change oil, plugs, exhausts, etc, but nothing major. Thanks

 

That's awesome!

 

after briefly looking at that it makes it look very simple...provided you have the right tools...thankfully my dad loves tools so I always have what I need.
