aluminum pulleys

does any one have or know where to get aluminum crank pulleys for xj???
or do they make tthem?

Im not really clear on the advantage of an Aluminum one over the traditional steel (cast iron, whatever).

Why would one want this? (not trying to be a smart ass, just curious)

I would NOT recommend swapping out a Crankshaft Vibration/Harmonic Balancer Pulley on Jeep 4.0L Engine for an Aluminum Crank Pully. However, here is something you may want to look at. I do NOT recommend it, however, it is your choice.

There is a Forum here on that may suit your needs better.
