ok, sway bar disconnects allow you to disconnect your sway bar for trail riding, which well really help off road ride and flex. Some people take off the sway bar altogether and save some money. Track bars connect your axle to your frame, keeping it in place. Most people agree that they are unnecesarry on a stock jeep, and on a lifted jeep, they do nothing but keep your suspension from flexing like it should. Take em off. Look up how to do it on this forum, lots of people have done it an done write ups on it, but its an easy, 2 bolt operation. Good luck!
