Fabtech 17-21 Ford F250/F350 4WD Diesel 6in 4Link Sys w/Coils & Stealth

This Fabtech 6-inch 4-Link suspension system for your 2017-2020 Ford F-250 or F-350 Super Duty 4WD Diesel gives you a substantial lift while improving off-road capability. What you get in this kit includes the heavy-duty 4-link arms, replacement front coil springs, a rear block and U-bolt kit, sway bar drops, a track bar relocation bracket, and a Pitman arm. It also comes complete with front and rear Stealth shocks to handle the increased travel.

The heart of this system is the 4-link setup, featuring 2-inch diameter, heavy-wall control arms. These arms use robust 1-inch Uniballs, which are common in racing applications for their strength and ability to allow for significant suspension articulation. The mounting brackets are made from thick 1/4-inch steel, designed to bolt directly to the frame without requiring any cutting or welding, making for a cleaner installation. This design allows the use of the included replacement coil springs, which are specifically chosen to work with the 4-link geometry and the 6-inch lift height.

With the 4-link system, you'll notice improved wheel travel and better articulation, which translates to a more capable vehicle off-road. The included Stealth shocks are built to handle the demands of a lifted truck, providing controlled damping for both on-road comfort and off-road performance. This kit is a comprehensive solution for those looking to significantly upgrade their Super Duty's suspension.
