These brake pads fit well and last even better on my 2015 F-250 4X4. I currently only use them with my stock rotors because they still have a lot of life in them. I plan to install Power Stop rotors next time I change the pads. The break-in process was easy, although I think I upset a few other drivers by doing so! I've put about 5,000 miles on these pads now, I regularly tow a 10,000th truck trailer (3-4 times a week), and these pads still look freaking new! Can't wait to replace them so I can upgrade my rotors too!
