So far, I've not seen any problems with Centric brake parts, even though their new parts are all imported.
Ford will give you a two year unlimited mileage warranty, I don't know about Centric.
If Motorcraft offers super duty pads (SD suffix on part number), I recommend them as they don't fade or dust the wheels.
Just my $0.02.
