This is an interesting question and one that I too have looked into. The rear can't be shackle dropped unless you want the shackle to prodrude into the bed. The rear of the 2500 is not like the rear of the 1500 there is a totally different shackle arrangement. It looks similar to a new Ford setup, but with no room to work the only way to maybe make it work it to cut into the bed to make room for the shackle, I know i tried this route already. Other rear options are to de-arch the leafs and add a helper bag set up.
On the front the easiest way to lower it is to move up the upper control arms and take 1/2 coil out of the stock springs, it will still allign and ride ok. There is NO drop kit for this truck, the front's bump stops are also very close and will need removing and some steel cutting back.
