need a little lowering help

[apachedaddy]

Ok guys, i want to order a lowering kit to be there for when i get home in july from iraq. did a search and found plenty of stuff but my real question is how low can i go without doing a bunch of mods on a statis drop. i know i will prob need a adj trac locator and i can do a c-notch if needed. just wanted to know how much i can go and have the truck sit level. any help would be great. thank you for your help.
