Unlike other adjustment-type bars, this one does not sacrifice your on-road control to allow off-road maneuverability. You can choose the amount of force/resistance you desire for your driving conditions. Through the use of a locking mechanism (hub), you can lock or unlock the sway bar completely. When unlocked, there is zero resistance on the sway bar and it moves freely throughout the suspension travel cycle. In the locked position, you also have three options of resistance with the three mounting hole options on the selectable torque arm. It�s a must have item for the avid off-roader and Jeeper.
