    • Delco quality at a discount price
Direct replacement for a 2013 GMC Sierra 5.3L . Installed easily & worked as it should.

    • Great replacment Item
I have over 300k on my 2008 Silverado, and I had issues with the voltage regulator in the original alternator, with voltage fluctuating. Tried this item and it only took about 15mins to change out. Problem was instantly fixed, love the quality of this item and ease of installation.

    • OEM part
I’ve never installed an alternator before but I thought with a You Tube video I’d give it a try. I’ve had flickering lights and battery problems with the after market alternator that was installed in the truck. 2011 Chevy Silverado. Easy change out and it only took about a half hour. A 15mm long ratcheting wrench made it easy. Engine light that was on before is now off and battery is being charged. ... show more

Review Image by Jeff C. Jeff C.
The write up for this on amazon says: "100% newly manufactured as an exact replacement for your GM vehicle's original alternator" - When I bought is April 1, 2015 and as I write this review on April 3, 2015. The box indicates "re manufactured". Shame on Amazon! I do not like false statements or false advertising! The box does state AC Delco and the item is an exact match to the original one that was on my truck. I went ahead and installed it as I needed a new alternator. Installation took less that 15 minutes. Hopefully it last 4+ years and 201500 miles like the original did. 2011 Chevrolet Silverado 1500 4WD Crew Cab LT Vortec 5.3L V8 ... show more

    • Works like a champ!
Easy to install. Box came from the factory. Looks brand new. So far working well in my 2008 Silverado.

    • Not New
This product is NOT new. Comes in a brown box and is definitely a refurb. I received one that wasn’t even built back to specs. Does not charge properly.
