My $0.32, FWIW.
Things you will likely need to do, assuming you move forward with your plan above.
Body lift: - fan shroud clearance issues, expect to modify
- Tcase linkage alignment...expect to either replace linkage with aftermarket adaptor, OR crawl underneath the Jeep to shift. About $50 (I've done both
)
Coils 3"+ : - for comfort and usability, plan on SYE and a new rear driveshaft. $600+ to your current plans
Tires...I would recommend 31", unless you plan to regear. We run 33's, and 4.10's, and dream of 4.88. Yes, it will be driveable, but you'll likely not be happy with it either in town or on the highway.
