The Fabtech 4-Link Lift System is a 4-inch suspension kit for 2017–2021 Ford F-250 and F-350 4WD gas models that increases wheel travel and articulation. Fabtech's bolt-on design uses heavy-wall 2-inch links, race-style uniballs and thick 1/4-inch brackets to attach without cutting or welding. The system includes sway bar drops, a trac-bar relocation bracket, pitman arm, U-bolt kit and performance shocks for improved suspension dynamics.
