I think FCS has the reputation of being the cheapest strut out there. Anyway won't work, that's RWD only. Mine is a 4matic with the sports package. Sports has a 1 inch lower suspension which I'm guessing is from the springs although there's a setting for the ride height on the strut so I guess it could also be just done on the strut. But I believe the rears are just the springs and shocks and no setting probably different set of springs for whether you have the luxury or sports package. No air suspension on the E-350, that was on the E-550/E63/wagon. Also that spring is just for classic/elegance which I think translates to the luxury package. Looks like they have two for the rear but they don't list an MB part number that you could cross reference it to. Had to get the MB strut mount pieces too which added up. For my 2011, the MB dealer had to order the springs from Germany.
