Good value
These looked just like the ones that came on the truck and are probably just as good for my purpose. There are a lot of much more expensive disks that claim to last longer and stop quicker and I can not verify their worth. I used them on the rear and that is only about 30-40% of the stopping effort for the truck. They will slide the tires and that is all I need. At the price I can afford to replace them every time I change pads (100,000 miles) so I think I got my money's worth.

Quality not bad

One Star
this product seemed of a good quality but did not fit my Silverado. Silverados (and I'm sure other GM vehicles) either have SINGLE piston calipers or DUAL/DOUBLE piston calipers. This product is designed for dual, which is why it did not fit for me since my truck has single piston rear calipers. I only assumed mine were dual since my front ones were. AC Delco makes rear rotors that work for single pistons

Doesn’t fit 03 Silverado 1500 5.3
I had tore my old ones off the night prior to these arriving, I was ready to install them as soon as I received them. Unfortunately upon opening I realized right away that they were going to be way to thick to fit the rear of my 03 Silverado like advertised. Returned a week ago now, I got confirmation from ups that they were delivered back to the Amazon warehouse 2 days after being picked up and I have yet to receive my refund.
