Hellwig now has upgraded Sway Bars for 2017 Ford F250/F350 Super Duty Trucks that you can purchese thru Marken Performance. The stock F250/F350 pick up trucks come equipped with an undersized front factory sway bar that does not provide adequate roll control and small rear sway bar or no rear sway bar at all. Now, Hellwig’s upgraded forged sway bars deliver drastic improvements to handling and body roll control, making the truck safer and more fun to drive. Hellwig Products offers an upgraded 1 5/16-inch solid front sway bar (part #7712) and a 1 1/4-inch rear sway bar (part #7761) for 4 wheel drive trucks. They also offer an upgraded 1 1/2-inch solid front sway bar (part #7713) and a 1 1/4-inch rear sway bar (part #7762) for 2 wheel drive applications. Its Big Wig 1 5/16-inch rear sway bar is designed specifically for heavy duty towing applications for both 2 wheel (Part #7320) and 4 wheel (Part #7321) drive, single wheel and dually trucks. The larger Hellwig front sway bar replaces the undersized factory bar and when combined with the added larger Hellwig rear sway bar, provides the ultimate improvement for daily driving and tow/haul. These bolt-on upgraded bars are forged from 4140 Chromoly steel, heat treated for durability, and feature a forged 3-hole adjustable end to allow you to tune the bars to your exact load and driving style.
