Fabtech 17 Ford F450/F550 4WD Diesel 6in 4Link Sys w/Coils & Dl Shks

Fabtech is known for building robust suspension systems that can handle tough conditions, and this 6-inch 4-Link Conversion system for your 2017 Ford F450 or F550 4WD Diesel is a prime example. If you're looking to significantly upgrade your truck's stance and capability for both on-road driving and off-road adventures, this kit is designed to meet those demands.

This kit features 2-inch diameter, heavy-wall link arms that attach to strong 1/4-inch thick steel frame brackets, ensuring a solid foundation for the new suspension geometry. The axle brackets are also 1/4-inch thick steel and include adjustable alignment cams along with Fabtech's 5 Ton joints, which pivot at the frame for a long service life. American-made coil springs are included, tuned to provide a compliant ride quality whether you're on the pavement or exploring trails. The kit also includes a dropped Pitman arm made from forged steel that exceeds factory specifications, and 1/4-inch thick steel brackets to control suspension travel and eliminate deflection, especially with the track bar.

To accommodate the increased ride height, the system includes 1/4-inch thick steel drop brackets that reposition the front sway bar, allowing its link ends to cycle freely without binding. Brake line brackets are also included to relocate the factory lines without needing to open the brake system. The factory steering stabilizer is retained with a 1/4-inch thick steel bracket and support brace to help reduce tire shimmy. For the rear, steel lift blocks replace the factory ones for additional height without affecting ride quality or load capacity, and American-made U-bolts secure the rear differential. The included Dirt Logic 2.25 shocks feature a stainless steel body and a NitroSteel piston rod for excellent corrosion resistance and durability, contributing to superior ride quality.
