Works fine out of the box.

Had to replace my old one because of bearing noise. The new one spins instantly and works well out of the box. There are no pulleys.

Pros
  • Alternators and alternators
Cons
  • Questionable purchase for the elderly

The Delco alternator was the perfect fit.

Perfect for my Chevrolet Truck. Very easy to install. Well packaged for shipping. Fast and hassle free next day delivery. Couldn't be happier.

  • Automotive
Cons
  • Secret

True Substitute. Fits exactly like my original.

This generator was at a good price and great deal. It turned out to be my battery but I installed that and kept mine as a spare. This works well and holds a charge.

Pros
  • Generators
Cons
  • Vulgarity

ACDelco 15263858 Alternator

Damaged. The main connection B+ is bent, the plastic housing is torn. The end nut was missing. The original packaging material and literature were missing. The original box was torn. Obviously this was a comeback that was likely scrapped. I returned it on credit. Bought the same model from Rock Auto which worked great on an 05 Silverado 5.3L.

Pros
  • Starters and alternators
Cons
  • There are new competitors
