Perfect!
Perfect fit for my Suburban. AC Delco OEM. Much better than the duralast or other generic brands from local auto store... And the price is right for OEM parts!

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.
