Rize makes the big 8" lift kit, which in my opinion is ridiculously priced. You can find it on ebay for a quick peek.
Truxx makes a metal suspension spacer kit that is something like 2.75 or 3" I dont remember at this point.
Daystar makes a front level or all around poly 2-2.75" lift kit suspension lift kit. I have the front and rear daystar lift kit on my expy and would recommend it.
I've taken mine plenty of places off road that it shouldn't have been, be prepared to make repairs if you get too rough with it - or at least upgrade to the NBX/FX4 skidplate package!

Nobody makes a body lift specifically for the newer gen expeditions. I purchased a 3" body lift made for the 04-05 F150 and plan to adapt it to mine. So far it all looks like it will work ok with the snags coming in the form of bumpers, and engine doodad relocating. I just want plenty of room for my 35"s to move around while off the beaten path.
That will be my project in the upcoming weeks.
