See my sig for pic of 33's on about 3" of lift, maybe a tad less, just OME 912 springs and a t-bar crank. As far as sand, it depends on where your at, when I lived in central florida I ran into plenty of mud but also sand and up here in north florida it's alot of red clay/sand/mud. I went with mud terrains but that's just me. I won't be playing in the sand a whole lot
