So I got a great deal on some Bilstein 5100 adjustable front shocks from a friend. They are for a 2013 4wd p# 24-187497. My question is will these work on my 2013 2wd? I currently have a 2" spacer and wanted to remove that and install these. I talked to Bilstein and they claim they won't work but could only say it was the valving that was different. What do all of you Ford F-150 wizards think???
