WJ front coil springs on a xj??

I just got a set of front WJ springs at work today out of one with a 4.0 do anyone know if they can be put into a 98 xj? i know the v8 zj coils give a 2-3 inch lift i was wondering if these would work on my DD i was about to order a budget boost but if these worked i would maybe just get some new leafs in the rear.
If anyone could help that would be great or if someone had a pic of what it did, if they tried it.

:huh:

i didnt think any wj's came with a 4.0..

4.0 , 4.7 or 4.7 H.O. im a chrysler tech ...... why i got the springs for free hahaha
