yea that doesn have to do with ur shocks, just your springs. Its doing that simply b/c they have less weight to put down, i have to add 1.5" spacers to level out my 4.5" rubicon express lift from my tnt bumper and winch

THIS IS A BAD IDEA!! Use synthetic oil in everthing ells but the diffs! Not one gear manufacture recomends them. The minerals needed to cusion the gears properly are not in synthetics.

I know I have heard that before.. Im going off aftermarket gear companies suggestions, And the experiance of the folks i work for. I personaly have seen more loud/burnt gears because off synthetics then i can count. The OEM diffs were not really designed to put up with the type of abbuse that we all put them threw.

I swear by Lucas additives and QS Synthetics in EVERYTHING. The synthetic is some pretty slick stuff, and that Lucas Oil treatment makes it slicker than cat**** on linoleum. Upgrade the ignitin system to high quality stuff from Mallory, MSD, or Accel. I use a MSD6T with an Accel cap, rotor and wires, and either AC-Delco or Champion Truck Plugs. Read your old plugs before getting the new ones so you can increase/decrease the heat range if needed.

Did you recalibrate mileage for the error considering bigger tires?
