motorcraft 75-140 syn for diffs and mercon 5 for transfer
If you have a locker in the rear make sure to add friction modifier to it or you will develop a chatter from the clutchs

Royal Purple is what I use. Same weight as Ford suggests, but you just can;t beat full-synthetic Royal Purple. They may cost just a hair more than some of their competitors, but the result is astounding. Check out their website. They put a lot of money into R&D and subsequently have gotten an awesome product. Just my opinion - take it for what is worth.
