Yeah, you're right about that. Weird. I was actually thinking about picking these up for my 2010 MKS 3.5 turbo and it's the same part number. Not sure why they don't have it listed for the 11 sho.
Your car uses the same motorcraft strut part as my mks, so i'd assume it's the same exact suspension. Not sure why the kyb's aren't listed for your car, but they are for mine.
