Quick Overview

The Fabtech patented Radius Arm lift kit for your 8-Lug Ford F250, F350 or F450 Super Duty also includes a trac bar relocation bracket, pitman arm, billet sway bar end links with heim ends, quad layer limiting straps, carrier bearing shims, and replacement rear leaf springs. The radius arms feature a full tubular structure strengthened by dimple die side plates, with an adjustable alignment cam at the axle to allow caster adjustment. Rear Dirt Logic 2.25 shocks are included.

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.

Fabtech recommends an upgrade to their adjustable trac bar sold separately.
