well i just bought my second jeep, first with a lift, and it has a superlift. my first jeep was almost 5 years ago so i don't remember right off hand how the ride was, but this one doesn't seem to ride to harsh with the lift. i THINK it's a 4" lift but i'm not sure. i just took pictures of the suspension if you want to see what it will look like when it's 5 years old. the springs are pretty rusty now, but winters in Michigan can do that.
not sure how much that helps, but thought i'd chime in.
