Quick Overview

For unsurpassed articulation and wheel travel, install the Fabtech 6" 4 Link system on your 8-Lug Ford F350 or F450 Super Duty. These large 2" OD heavy wall links feature race style 1" Uniballs for superior strength. No cutting or welding is required to secure the 4 Links to the frame using the thick 1/4" steel brackets.

Front lift comes from our Dirt Logic 4.0 Coilover Shock conversion that replaces the stock coil spring buckets with the Fabtech Coilover conversion towers with super stout gusseting. This conversion system is specifically designed for the Fabtech Dirt Logic 4.0 piggyback adjustable coilover shock. To complete this conversion, opt for the optional Dirt Logic Hydraulic Bump Stops sold separately.

Also included are billet sway bar links with heim ends, quad layer limiting straps, trac bar relocation bracket, pitman arm, carrier bearing shims and a rear block & u-bolt kit. Rear Performance shocks are included.
