I had a 2005 Avalanche that I bought this for and used for about 2 months. Still in perfect condition. It works on 2005 and up Chevy and GMC vehicles with the 2-wire alternator connection.
I bought an Excessive Amperage custom 300 amp alternator about 3-4 months ago for my 2005 Avalanche. Since then I have traded it in so I have this alternator left over. I'm asking $400 for it. It is for the 2-wire connection.
