No, there is not. To adjust it you have to have adjustable suspension links. But back to your shakes. The braking issue is probably a warped rotor which you did not notice before. When you lift a Jeep, it will start to exhibit this shaking you did not have before due to the new angles of the suspension track bar and drag link. The most likely culprit for all this is the track bar bushing. Have someone saw the steering wheel back and forth with the engine running while you inspect the track bar attachment points as well as tie rod ends. If anything moves at attachment points, it needs to be fixed. You might want to adjust your steering box too
