Careful with the stock alternator

I honestly didn't get to use this item because I was unable to remove the old pulley...to the point the pulled got cross threaded. So be careful if you decide to swap them! But the item is soundly constructed and looks fantastic compared to stock! Will attempt another install when I'm brave enough to fool with a $600 alternator again! (2021 ascent)

Matt,

Thank you for your 5 Star Review! We appreciate your honest feedback about the Perrin Alternator Pulley. Sorry to hear about the trouble during removal, but we are glad the part itself exceeded your expectations. Best of luck on your next attempt!
