The QDII system in the WK is true lockers. They automatically lock and unlock as conditions require it. I'm not sure why Jeep ever decided to call them what they did, but they are lockers front and rear. The QDI system is brake based, but still works fairly well.
I had a completely stock 07 WK with the QDI system and the 4.7. It even had stock tires. I took it out from time to time playing on some easier stuff that led me to some stuff that I should have been on. It really surprised me. I was with some lifted and locked TJs and could do everything they did, at least that my ground clearance allowed me to do. It really was pretty capable rig.
I ended up trading it in on a 09 JK because I got rid of my old trail TJ and wanted a rig that could do everything. However, for a rig that will see daily driving and mild wheeling / exploring a WK is hard to beat in my opinion. A mild spacer lift will allow you to run 31s or 32s and it would do most everything you would need. If I had the money, I would have another one, but I needed something more hardcore for the rocks and stuff I play on.
