I did a D60 conversion combined with a front shackle reversal and rear shackle flip (fronts also have a 1" add a leaf). I tossed in a set of rancho rs9000x's for shock duty. Problem I have is that my truck bounces like crazy. I can run a dirt road at 70mph and it'll be smooth as glass till I hit a dip, then I bounce like I have no shocks. I have tried settings 1-9 in all combos and at setting 1 it is like there is no shocks, and at 9 it is o.k., but when I hit big "whooops" in the road I get sea sick. Little bumps that are real hard and fast are no problem, but slow gradual changes in road surafce leave my rig bouncing everywhere. Do the 9000x's just not have the damping ability my 7200 lb beast needs? I have ridden in my buddies jeeps and at setting 9 their rigs'll rattle your fillings loose. They run at setting 3 most of the time on pavement.
