Maybe a dumb question, but these three pulleys are crank, jackshaft and alternator? And are they aluminum or steel?
The crank pulley is aluminum. It is actually lighter than the SCI crank pulley from the SCI underdrive set that I bought, so I kept the ASP crank pulley since it was lighter and not easily seen.For the crank-waterpump-alternator dude... And they are steel....had the same set before, but the crank might be aluminum....
