Fabtech 17-21 Ford F250/F350 4WD Diesel 8in 4Link Sys w/Coils & Stealth Shks

When you're looking to give your 2017-2020 Ford F-250 or F-350 Super Duty a serious suspension upgrade, this 8-inch 4 Link Conversion System from Fabtech is a comprehensive solution. It replaces the factory radius arm setup with heavy-duty 4 Link components, designed to enhance both your truck's capability off-road and its manners on pavement. This system includes the necessary coils and Fabtech's Stealth shocks to complete the transformation.

The advantage of this 4 Link design is twofold. On the road, it offers less caster change throughout the suspension's travel, which translates to more stable and predictable steering. When you venture off-road, the 4 Link geometry provides greater articulation than the stock radius arms, allowing your truck to tackle rougher terrain with more ease and at higher speeds. A key feature unique to this 8-inch system is Fabtech's extended-length Track Bar. This component is crucial for addressing the sensitive steering box found in late-model Super Duty trucks. It's 4 inches longer than stock, offset to the driver's side, and mounts with a robust 1/4-inch thick steel bracket. This setup helps bring the Track Bar and Draglink closer to a parallel angle compared to the factory setup, reducing steering push and allowing for full lock steering with up to 15.50-inch wide tires on 4.75-inch backspace wheels.

Fabtech has proven this 4 Link system over a decade in demanding commercial and military applications, ensuring it's built for long life even on a daily-driven vehicle. This kit comes with a 5-year, 60,000-mile powertrain warranty for added peace of mind. For a complete understanding of the components and their benefits, refer to the detailed features list.
