I want to lift my 1998 jeep grand cherokee, at what point to i need to upgrade axles?

[Noah]

I have a 1998 jeep grand cherokee with the 4.0 straight 6 4X4 that i plan on lifting. I am ordering JKS adjustable control arms all the way around, JKS rear and fron adjustable track bars, JKS quick disconnects, 5.5" re coil springs and Edelbrock XT series shocks. With this set up would i have to upgrade anything else? such as axles? If i lift it 5.5 inches and put some 33 in tires on it wont i be fine? or will i need to upgrade axles? Can i wait it out while i save up more if i dont drive it to ruff till i get new axles? thanks
