I went with Powerstop Rotors and Pads on my Ram, and they work great. They help stop my 7,000 lb boat. They have a little over 30k on them now and they show minimal wear and no warpage whatsoever. I got them through autoanything and they were considerably cheaper than the competition.
you can get all 4 or just the front 2. I just did the front and will do the rears when the pads need done.
