Welcome back Gunnar. The RoadActive Suspension Custom Leaf Spring Enhancement Kit item # RAS3611-SLHD is the correct one for your 4WD 2019 Ford F-350 dually. The RoadActive item # RAS686FR does not work with F-350 duallys.

The RoadActive Kit item # RAS3611-SLHD provides 3,000 lbs of load leveling support. It's designed to bolt directly to the top of your factory leaf springs to help with sagging, sway, body roll, and bounce.

Please note that the RoadActive Kit item # RAS3611-SLHD does require the removal of the top overload springs if your truck has them. This kit can indeed be returned if it doesn't fit. I checked with RoadActive to confirm this is the correct one so you won't have to worry about that.
