I have a 98 xj with an ax15 trans and np231 tcase, also running a Chrysler 8.25 rear. I just bought an IRO hack n tap kit. From what research tells me, this makes for the longest rear shaft length being the ax15 is shorter than aw4. I've read that most running this setup have to use a 93-96 zj front shaft i6 or v8. I'm at 4.5" of lift. Can anyone give me a straight answer on whether I'm correct or not? I'm trying to make this a simple install without multiple runs to the JY. Thanks

 

Install sye then measure only for sure way, theres a list that tells you what years to look for.

mesure from the end of the output shaft to the center of the ujoint the front is center to center unless you have the tin can style (gnk) then face to face at ride height
