Tbar,
Give us a call, what he wants are Powerslots and Hawk Pads. Stay away from drilled rotors on a heavy truck they tend to crack between the holes and the slots acheive the same result with no cracking problems. I have a full set on my 6.0 and have been amazed at the stopping power and lack of fade as compared to the stock system. Be sure you follow the bedding in procedue for the pads and replace the caliper slide pins when you do this change over, makes for a trouble free install! Give us a call we have great prices on them.
