Qb Supreme Alternator, New
Price was right
Installed fairly well. Ran in no problems putting it in. Had it in place in less then an hour and I'm 76 years old.. Seems to be working just fine, but only time will tell.. I like that it's 136 amp and not just the OME 90 amp an only costing a few bucks more for a new and not rebuilt..

Qb Supreme Alternator, New
I am a retired journeyman automotive master tech. 40+ years at new car dealers. This alternator is the exact fit. It looks right, fits right, and works right. I would have no problem buying again, or installing on my truck. I do recommend buying a new part and checking the reference of other buyers. This company checks out as good to do business with.
