4.0 5 piece combo kit red or blue [4.0combo] - $419.00 : Underdog-Performance, The Art of Power

saw these. is it worth the money? i understand what they do, just want to hear what someone says that bought them. and are they hard to install?

 

bump

 

i would say they are worth it i had just a crank pulley on my probe gt and it seemed to free up a little

 

Search man. Everyone that gets them loves them. Don't get the idler pulley though. It is just for show.

 

I have them for the 3.0. Not to bad. Good for the money. Got like 1 mpg and revs quicker and looks cool in the engine bay. Don't know about the 4.0 ones but if they are like mine then they are a good bang for your buck

 

I doubt you will be disappointed. Wayne is a top-notch guy to deal with, and everything he sells is good stuff.

 

i would run them if i didnt have a supercharger.

 

I would only buy the crank pulley and maybe the alternator pulley if you have a stereo with an amp or have a few offroad lights.

 

sounds good. buy the whole kit or just certain ones? i know the crank pulley would be worth it, the altenator might be ok since i have a few extra lights, the water pump pulley i have no idea about and i dont need the idler pulley.

why is the crank pulley so pricey?

 

Because the crank pulley has the teeth on it for the crank sensor.
