Unless you change your lower pulley you don't need to change your stock alternator pulley.
If the lower is stock leave the stock pulley on the alternator.
It might even be safe with a 2 pound lower. But when you get up to 4 pound or higher it is a must to slow down the alternator with the bigger alternator pulley.
