huge lifts are only useful if you're gonna roll with 56 inch tires or soemthing and you need the body lift to get clearance for the tires.. so it'll lift your axel higher.
not practical for a daily driver, those trucks need to come off the trailer and into the mud and back on the trailer.
nice jeep, tires do look bald in the pics though : ) maybe time for some mickey thompsons, i have a CJ5, 1979 with 35's thompsons, got it stuck once in pretty much the same situation you have there, deep mud sucks.
