These heavy duty control arm drop brackets help reset JK control arm angles to a more natural and comfortable geometry. By reducing the operating angle of the front control arms, the force applied to the arm when hitting a bump is now directed up into the springs instead of being absorbed into the frame. These drop brackets allow a JK with 3in to 4in of lift to operate more like stock, with a more appropriate geometry to increase force on the front wheels. More force means more traction in straight line braking and reduced weight shifting and inertia when braking during a curve.
