KDSS is a double edge sword. For 95% of buyers, I think it is a good thing. It will improve off-road capabilities in an automagic way without impacting on-road manners.
It is basically a hydraulically controlled sway bar tensioning system.
Here it is explained in laymen terms.

It will work fine with a lift. It won't allow for extreme articulation that one might want for extreme off-roading. As bimrunner mentioned, this requires long travel. Since our 5th gens have IFS long travel is still very difficult to obtain in the front, but it is very achievable in the rear (where it is actually more important for traction...) Most lifts are good for about 10-11" of wheel travel in the rear. Long travel will get you as much as 18" (I'm honestly guessing here because I don't know the motion ratios). That is all in the form of additional down travel (think longer legs). To get true long travel you have to remove the sway bars completely and that is a PITA with KDSS, yet super easy without.
This is not a 4 runner, but an FJ with the same suspension. This is long travel in the rear. I'm sure bimrunner has some pictures of his truck flexing. That is not lift (the truck is just lifted 3") it is added down travel.
The next pic is my truck. Currently without Long travel (I'm working on changing that very soon, it's not that expensive....). It will give you and idea of why long travel is so desirable in extreme terrain. I actually have the rear sway bar on with extended links in this pic. So it would be a little better with KDSS, but not by much. With long travel, both rear wheels would be well planted on the ground.
If you are just doing easy trails...long travel is rarely if ever needed and you can usually get around it with recovery or just picking perfect lines...
