This Hellwig Big Wig rear sway bar is a bolt-on handling upgrade for the 17-26 Ford F-250/F-350 Super Duty 2WD, including single and dual rear wheel (dually) models and F-250 cab and chassis. It uses a larger 1-5/16in solid, heat-treated chromoly bar that cuts body roll and adds stability under load, while towing, and through corners, and it offers multiple rate settings so the stiffness can be tuned to the load.
