I installed these today (rear) on my Dodge Ram 2500 HD 2007.5 6.7. I didn't need the OEMs to put in 100,000 miles, but they still had 1/4 inch of meat on them. Ok these new pads are holding up well, haven't used them with a trailer yet. Fronts were replaced at 79,000 miles, best replacement at 50,000 or so.
