You don't have to be Isaac Newton to know that when a moving vehicle makes a sharp or abrupt turn, the force shifts outside of the turn. This invariably pulls one side of your Jeep closer to the road, while the other side rises up a bit. That is, unless you have a sway bar. These simple but effective devices attempt to keep the Wrangler's body flat by transferring force from one side to the other. This is generally a good thing, except when you take your Jeep Wrangler off road. Since sharp, fast turns are uncommon on unpaved trails, any benefits you might gain from the part pales in comparison to what you might lose in performance, which is why sway bar disconnects are popular off-roading accessories.
