Coyote alternator question

[cfriedman67]

There seems to be an extra pulley in the box. Do I replace one of the pulleys already installed?148282148281

This is a gen 3 coyote and the alternator is the m8600 m50balt from Ford performance

Thanks

I received an extra one too. Keep it for a spare

Not sure it matters -- but since it looked a bit different than the one on the engine, I used it and saved the original as a spare. Still in the "extra parts" box.
