I've had the same setup on mine for ~5 years now. 2.7" of lift up front and 2.2" rear. I've got the 4.0, auto trans, OEM front bumper with no winch, 33" spare and MORryde kit in the rear, soft top and run with the rear seat out. I did wind up needing an SYE, and did adjustable control arms shortly after the lift, as the OEM bushings were shot.
Initially, I installed the JKS discos when I did the lift. They were great, but in the last year, I upgraded to a Swayloc. Well worth the extra $ if you plan any serious wheeling and budget allows.
