    • Great Value!
Worked perfectly for my 2015 Tahoe LT. Was brand new and came in AC Delco box and packaging. This alternator was $250 less than AutoZone and O’Reilly Auto parts. Great value!

Review Image by Dusty Rhoads Dusty Rhoads
So it turns out, my truck's computer fooled me into thinking I needed an alternator because the voltage meter kept dropping. Silly me didn't realize the computer "alternates" the voltage to the battery regularly, and you don't even notice it unless you're watching it. As long as your gauge doesn't go above or below the warning marks, then you are fine. GLAD I REPLACED IT ANYWAY since my old alternator was 11 years old, and I run a lot of LED nonsense off one battery 👍 ... show more

    • OEM PART
Installed took about an hour was getting a lot of noise from the old one n didn't really trust a no name brand one. The brick and mortar store wanted $480.00 for the same brand new. So half the price came in a big OE box was a tight fit but so was the old one all around so far so good
