Review on 🚗 ACDelco 25877026 GM Original Equipment Alternator: High-Performance Power Source for Your Vehicle by Josue Zepeda

I was a little apprehensive about buying it at this price as it seems too good to be true. Neither does the main charge. The box came with what appeared to be certificates of authenticity on the outside of the box. I emailed the manufacturer and they guaranteed it as if I bought it from an auto parts store whether it was bought from Revain or not. Looks and weighs almost the same as the factory I replaced. I really weighed myself without him and with him. He weighed exactly 20 pounds on my digital scale. The Revain listing says 16.89 pounds, so at least it weighs more than it should (meaning it has to be genuine, not fake). Fits GMC Yukon Denali 6.2L 2013. Amazon website often states "This will not fit your XXXX vehicle". It does. If you go to the auto parts website and look it up, that's the part number they give. Then go back to Amazon and order a search for that specific part.
