Try running about 17 lbs rear, 23 lbs front to start. You won't pop a bead, especially running stock rims. I find with mine, for the weight distribution of the Trackicks, 5 lbs less in the rear gives an even ride with better suspension compliance. I don't even remember what mine was like stock, but it certainly was never as " harsh " as you describe. Also, Forget what RR told you, OME stuff rides WAY better than stock stuff. Expensive yes, but worth it. How many miles on your rig? It may be time for replacement stuff anyway. Do your rear shocks work through their travel smoothly? Disconnect them and try moving them through their travel by hand, should be smooth and with some resistance. Are your rear coils binding somehow? Also, do you have all the stock equipment in your truck? backseat, etc? I carry a box of spares weighing about 85 lbs, strapped to the floor in the back. At first it was just for my cross country trip, but I found the extra weight made it ride a lot nicer so I just leave it in now.
