The Fabtech patented Radius Arm lift kit for your 8-Lug Ford 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, a rear block and u-bolt kit. 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. The upper coilover mounts are constructed with 1.75 diameter DOM tubing that replace the factory coil spring mounts and span across a wide section of the frame for proper impact load distribution. The lower mounts are 1/4" thick steel that attach to the axle housing. To complete this conversion, opt for the optional Dirt Logic Hydraulic Bump Stops sold separately.
