More info

Obtain maximum front suspension damping for Super Duty's with our Dirt Logic 4.0 Coilover Conversion system. The upper coilover mounts are constructed with 1.75 diameter DOM tubing that replaces 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, providing solid mounting points for the Dirt Logic 4.0 Coilover piggyback reservoir shocks. Also included in this system are billet sway bar end links with heim ends and quad layer limiting straps.
