What did you do about your pinion angle? Did you shim the leaf pack? I am planning on relocating the rear shackle mount up about 2" and forward 3". I want more droop than stuff so I plan on a 30 degree or so shackle angle. The 52" leaves I am using are Tuff Country 2" lift rear springs. I removed 3 leaves and the overload so they are very soft now, they flatten out with only a small amount of arc. I would guess they offer around 2-3" of lift over stock.
