Perfect replacement on my 2500HD truck
Just right as my old ones lasted 110K miles and were getting warped. These were cheap enough that purchasing them is better than cutting down the originals.

OE Rotors - only way to go
Have used these on a few different HD trucks - make sure you check the opening size for you application - these have the larger 4.8 opening which is needed for the HD trucks - I mention as Amazon may inadvertently tell you the smaller 4.6 fitsQuality rotor - easy to install

Warped within the first month of use.
These may be GM but not sure if they are OEM I did a lot of research and thought these were original OEM, but they still started shaking soon after install.

Annoying overspray
Annoying paint over spray, you'd think with how much these cost they could add an extra step to the manufacturing process to prevent that. I was able to clean it off with scotch Brite and some brake cleaner. It might be fine to just install them with the paint on there but I don't cut any corners when it comes to brakes. The original rotors on my 2006 Duramax lasted 225k miles until they warped. These are OE replacements so they should last just as long.

Nothing better then GM original Equipment, my truck had a terrible vibration while braking these were incredibly easy to install and worth every penny.

Good OEM replacement
I'm only giving these a 4 star review at this time. If they last as long as the originals I'll edit this review and give it 5 starts. Easy to install.
