These King Superlift edition Coil Overs come completely assembled and ready to bolt in. No assembly or spring compressors needed.
For Superlift's part, OEM CAD models and the latest 3D design software were used to precision engineer a suspension system that hinges around a set of massive, high clearance tubular radius arms designed to bolt right into the factory mounts. These heavy duty radius arms use the giant press fit OEM Clevite bushings to reduce noise, vibration and harshness (NVH) feature a flat jack plate, include alignment cam bolts and are offset to the inside allowing maximum turning radius and tire clearance.
The 4" lift also contains a new track bar relocation bracket to ensure proper steering geometry and track bar phasing. The rear lift is achieved with a new design fabricated rear block that allows the removal of the stock block.
Avoid the long wait times and high costs associated with one-off builds. Make the ultimate upgrade to your Super Duty with the King Superlift edition Coilover Conversion Systems from Superlift.
