I installed mine a few weeks ago. After driving several trails I can tell you that the difference is tremendous. The Jeep feels far more controlled when the suspension is working. When the Jeep is leaning, the body doesn't flop to the low side the way it would when disconnected.
The Antirock provides increased articulation over the stock sway bar while giving stability and control that is simply not available when disconnected. It is the single best thing I have added so far.
