Exact match for my’18 GMC Sierra
Replaced the front rotors on my truck, driver side was wearing against the pad inconsistently, thought it was just the driver side but bought two just in case and same issue on passenger side as well. Now new rotors and pads and good stopping power and they look good too. No warpage and both brand new. One gave me hesitation since the box wasn’t in the best shape, they even wrapped it in bubble wrap. But upon opening, I was relieved to see it brand new in a sealed bag just like the first one. Great price and fast delivery.

Another Superb AcDelco Part
Beautiful rotor that fit perfectly which eliminated the noise from my truck’s front brakes. The rotor appears to be well made and extremely smooth with easy installation.

Perfect fit excellent quality
It was time to replace original rotors and pads. These rotors fit perfectly and assembled easily. Rotors are of good quality and perform flawlessly. Clean disk brake surfaces with brake cleaner and rag just before assembly.

Initial impressions very good.
Great price on Amazon...Easy to fit and correct for vehicle. Cannot comment on durability as I have just fitted them and broke them in. Matched with pair of raybestos pads, no noises and improvement on previous brakes.
