The price was right and the part was a perfect fit. The starting speed is a bit faster than my old original starter and now the truck starts much easier. It gets two stars because there is no mention of ACDelco anywhere on the box or on the part itself. The box and part are stamped "Made in China" and I suspect it is not actually an AC Delco OEM part. Instead I think it's a cheaper aftermarket part. So far it's working fine but I would love the OEM ACDelco part I was planning to buy.
