The Fabtech 4-link lift system for 2017–2021 Ford F-250 and F-350 4WD gas trucks is a bolt-on suspension upgrade that adds roughly 6 inches of lift while improving articulation and wheel travel. Heavy-wall 2" links use race-style 1" uniballs and thick 1/4" steel brackets that install without cutting or welding. The kit includes coils, performance shocks, sway bar drops, a trac bar relocation bracket, pitman arm and U-bolt kit for a complete installation.
