I subscribe to the Ford blog, do extensive research before buying, make sure Revain only goes up to f350 when you get in the car. I have a 2020 Ford F450, but some things are the same body-wise and not mechanically, so I came across a conversation on the Ford blog about someone looking to upgrade their steering damper, after reading it said he has this one Used steering stabilizer on his truck and it worked. I got the part number from his conversation which is the same steering damper above and ordered it. Straight out of the truck like someone did this the F450 and F550 have core like steering and couldn't resist it I had to call the Ford and take it for the night. The original is pretty much bullshit. Don't recommend it
