Fabtech 17-21 Ford F250/350 4WD Diesel 6in 4Link Sys w/Coils & 2.25 Dl Resi Frt & Dl Rr Shks

The heart of this Fabtech 4-Link system for your 2017-2020 Ford F-250 or F-350 Super Duty is its heavy-duty tubular Radius Arms. These arms are built with a reinforced tubular structure, featuring dimple die side plates and substantial gusseting, drawing design cues from Fabtech's race components. This robust construction makes them a significant upgrade over the stock stamped arms, and this design has a proven track record in military applications for over a decade.

This complete suspension upgrade is designed to handle both on- and off-road demands, providing the extra strength needed for oversized tires. The system includes Fabtech's own 6-inch lift coils and Dirt Logic 2.25 stainless steel reservoir shocks for the front, paired with non-reservoir Dirt Logic shocks for the rear. These shocks are specifically tuned to work with the Fabtech coils and larger tires, aiming for a comfortable and capable ride quality on any terrain. The 2-inch diameter, heavy-wall links feature 1-inch Uniballs for superior strength, and thick 1/4-inch steel brackets attach the 4-links to the frame without requiring any cutting or welding.

Beyond the links and shocks, this kit also comes with Sway Bar Drops, a Trac Bar relocation bracket, a Pitman Arm, and a U-Bolt kit to ensure a comprehensive suspension transformation. Fabtech backs this system with a free 5-year, 60,000-mile powertrain warranty, offering added peace of mind for your investment.
