I installed the sway bar offered at Chevy Duty. It was a thick u-shaped sway bar that mounts under the front cross member (requires no drilling) and the ends attached via a bolt and bushings to a plate you install under the lower piston shock mount. It worked like a charm!! It does not bounce nor rotate to the right or left under acceleration or deceleration. I might now be able to go tremendous speeds but I certainly can travel highway speeds confidently.
