Great product, fair price.
No issues, perfect fit as expected. Could not beat the price compared to local auto part places. I got 2 AC Delco drums for what it cost for just one locally.

Cheaper than a scrap yard.
I was able to get this to my door step cheaper than the price I was quoted by the scrap yard. Works great for my forge.

Rear drums
The drums that I bought for my 06 Chevy Equinox Were defected when I applied the brake it's like putting on the brake and releasing it fast When coming to a stop. And then applying the brake again really fast and then releasing. they must have been dropped at the warehouse from a high Storage area And fell down below Landing on the Drum side on the pavement maybe a bunch of them were on a pallet or something. So yeah that's the problem with them. overall my brakes went back up again I have breaks now . my old drums had 30000 500 miles on them. I guess I will have to go biomix parts store their little mark expensive but at least if I have the same problem I can return I have 1 year warranty on the there.

I would expect better quality from GM, but these disappoint. Right off the bat i noticed the machining of these drums were not up to standard as witnessed after a 1500 km inspection. They required machining to true them up
