The back are stock leafs but i have airbags in the back as well which i put 50lbs in to lift it a bit. As for an alignment.... im taking it in for one after i bring it down another full turn maybe 2. It needed an alignment prior to this anyway. Havent measured the fenders but im thinking it's a bit on the high side still. What should the fenders be at to be in the safe zone? Looking to be at about 1.5" taller than stock. I did a measurement prior to lift but with the snow being uneven ground i think i am off a bit.
