This Hellwig rear sway bar is a bolt-on handling upgrade for the 11-16 Ford F-250/F-350. It uses a larger 1-1/4in solid, heat-treated chromoly bar that ties the suspension together to cut body roll and add stability under load, while towing, and through corners. It mounts in the factory locations with the included hardware, and it offers multiple rate settings so the stiffness can be tuned to the load.
