Only disadvantage is the lower output of the alternator. Not a big deal if your running stock stereo, but if you drain more juice don't put on the alternator pulley, just the rest.

The March Performance udp set (3 pc aluminum) uses the same size alternator pulley, so you get the same output as the stock. I just put a set on my truck and I love them (thanks again Wicked X).
