2013-2018 Cummins 4" 4 Link Lift Kit (BDS697H)
Convert your Cummins away from the problematic factory radius arm suspension setup to the custom BDS Suspension 4-Link system. The design starts with 2 massive frame brackets that provide the mounting points for the new upper and lower control arms. These brackets locate off of the factory radius arm brackets, no factory bracket removal is required. The new 4-Link brackets mount is similar to the current radius arm relocation brackets, wrapping the frame and nesting in the factory radius arms mounts. As with the radius arm brackets, there is a minor amount of welding required to install the threaded frame insert (1 per side). This insert is necessary to provide the strongest possible mount.
