Pretty sweet deal, looks like UCA's and LCA's in there, and I'm definitely going to check if my XJ is compatible.... I'm thinking it is.

 

That is for a Grand Cherokee so it is setup a little differently especially since it has coil springs in the rear instead of leaf springs.

 

you can use everything in the front, the zj coils will give you a weebit more lift than 4" though.

its an ok deal if you could use all of it

 

I would think the front end stuff should work fine. You should get about 1 inch additional lift in the front since you are using GC stuff. I used GC coils on my XJ to achieve 3 inches of lift instead of 2 that the normal Old Man Emu coils would have provided.
