Everything is now SOLD...

 

do you know if the pulleys underdrive the alternator? or only the other components, or are they just lighter?

 

The pulleys are now sold.

To answer your question vapo- they are not only lighter in weight but are also designed to have a different ratio than stock, so yes they are slightly under driven. I have not heard of any lighting or electrical current issues with these.

vapo check your pm.....
