[Stocker]

I don't have pics, sorry -- but I do have stock rear springs on my light-duty K20, with add-a-leafs that I put in a long time ago.

Not counting the add-a-leafs, I have a 5-leaf pack that's ~2" thick, plus the ~5/8" spacer atop the spring pad.

If your sticker says HD springs, I believe that would be your spring pack, not something extra. Any additional hardware would be overload springs.
