There is no direct bolt on option to upgrade your single piston, hub pressed in rotor style brakes. I think the 'easiest' way would be to do the ford brake conversion. I still have some of the parts to do this project for my old 99, never did it, ending up selling it. The earlier 90's ford dana 60's interchange with our danas. You cant interchange the newer 01. 5+ dual piston brake assmebly. I wish it could have been that easy when I had the old truck. Do a search on here, it has been done. I think it is member Jmcoy that has a nice write up on it, helped me out getting necessary parts, correct yrs, etc. If that doesnt suit you, running slotted rotors with a good pad like hawk or ebc is about the best you can do.
