Howdy, I have been thinking about adding a set of underdrive pulleys and while researching I found Jusnes was listing the Mac pulleys from 97-06 but on Macs website they only list them from 97-03.

The same with a couple other vendors listing BBK's and Mac's. I was trying to find more than just the ASP Troyer carries to compare. Does anyone know if the 97-03 5.4L pulleys will work on the 3V?

Jusnes is normally pretty darn good but I want to hear it from others who aren't selling them. Also, I posted this here after searching and I didn't find the answer i was looking for, sorry if this is a beaten subject.

 

im dont know for sure, but i think they are the same...

 

have you talked to josiah?? i dont know what kind he has..

 

I think he got them from troyer.. so that would make them the asp pullies..

 

Yes, Josiah had the ASP ones.

The other interesting thing about the Mac one's is they state they don't lower your alternator output at idle so no low/slow charging problems...

 

also if you have a tuner you can bump up the idle a little, there worth the money.
