Does anyone know where i can get a set of underdrive pullys for a 3.9? Not stock one's need aftermarket to pick up a little power

 

www.krcperformance.com should have them.

 

jcwhitney.com, performanceproducts.com,stylinconcepts.com

 

And it is spelled "pulley". This might help if you are searching.

 

please excuse my ignorance, but what is an underdrive pulley, and what do does it do???

 

underdrive pulley's are smaller then the originals to slow down the accessories and they give you a bit more power. I'm thinkin on just doing the crankshaft one, but I dont feel like buying another belt. I just bought one last year to by pass the A/C. these belts are freakin expsensive

 

ok so for my what will be my daily driver once i get my license this would really not make a hell of a lot of difference i assume, so im going to leave that off my list of mods as i am looking to give my truck a little more kick off the line and some more cruising power . . . if i can cheap enough

 

Thanks for the input i've looked into all of it found a few things but nothing is certin yet ya'll know how it goes haha.

 

you know you would gain more HP if you just replaced the fan clutch with an electric fan.

 

I'm not a big fan of them. I've had two and have had trouble out of both of them. Not going for any big number's with the v6 just lookin for a little more. I have a 5.9 I'm eventually going to put in.
