You can get the kevlar pads and steel lines from EGR and it will make an improvement. The works from EGR was at $900. It includes slotted rotors, blueprinted calipers, pads, lines and fluid. Their calipers uses silicon seals and takes the heat better than factory. Heat is the killer on these trucks. Several aftermarket suppliers sell brake upgrades for Rams, but most are the 1500 series. Hard to find for the REAL trucks.
EGR advertises on TDR so look them up and price what they are now. I did mine over a year ago and haven't had any pull or problems since. Pads aren't showing any wear and I do the hardest driving you can do with these trucks. Back and forth to work thru town 13 miles each way.
If is don't burn oil, it ain't a truck!
