I spoke with a Fox representative yesterday who told me they were about 2 months away from releasing the Steering stabilizer that correctly fits the geometry of the 2018 Super Duty trucks. I know there is another thread with part numbers and what not but just FYI the stabilizer that fits the 2017 will not work with the 2018 without doing damage as others have reported. I know this information is not consistent across multiple sales sights online who continue to reference the part number for the 17's as being correct for the 18's. I repeat it is not but one is on the way.
If anyone has information inconsistent with what I was told by both Fox and my Fox dealer yesterday please share. Bottom line we need to make sure we are getting the correct part number for our specific year model truck.

 

There's nothing different between an 18 and a 17.... If you get the stabilizer that still has the rubber slide bushing on the shaft, just cut it off. Not a big deal.

 

 

I installed one on a 2019, it was exactly the same as 17... Not sure why 18 would be any different?

 

 

Same as what everyones installed, the 985 part #.

 

 

Installed mine a few months ago. Have put more than 3000 miles driving all over the western US - zero issues.

Did carry along the old one - just in case something happened.

2018 with Fox 2.0 shocks. I'm currently running 63LBS in the stablizer and tires are 285/65-20 MIchelin LTX Defenders.

Anyone have a picture of the failed stablizer?

 

There's pics of the stock and Fox stabilizers side by side in that thread from last year on here. I didn't read to the end of thread but there were a couple of guys who reported damage. Others said it was fine. Who knows??
I think I will keep calling Fox and see if their response changes. My dealer straight up told me he wouldn't sell me the wrong stabilizer for obvious reasons. I respect the heck out of him for that.

 

 

Brick, that was my assumption as well but was in direct contrast to what I was told by Fox and my dealer. That is what got me to verifying and hence the responses and experiences have been all over the board so I am no more settled right now than I was when I started.
For an idea into my hesitation let me provide a glimpse into life in my world. I live under a black cloud. I honestly should write a book. Latest example. My JD Zero turn mower that I bought new in 2001 is approaching 1000 engine hours. Always well maintained. It stays at my farm where my brother lives next door. He uses the mower to mow his yard as well. Yesterday he calls me to tell me that the PTO switch has failed. Still has the original switch on it so I stop by the JD dealer and get the replacement part. I open the box and it appears to be new. Get to the shop and replace the PTO switch. Nothing. Then I get to looking at the "new" switch a little closer and its obviously not new as there are tool marks under good light that can be seen where it was removed. Someone bought a new one, took the old one back for a refund as the new one and it got put back on the shelf. I was the lucky guy that bought it again. So that screwed my whole day of mowing up since the JD dealer closes at noon on Saturday. That is just one example of things that happen to me daily so I hope that helps you guys understand why I go above and beyond to prevent bad things from happening. I would be the one guy that had a catastrophic failure with this steering stabilizer if there was any chance of it ever happening. As my Dad used to say some people can ***** in a swinging bucket but I am not one of those.

 

 

 

My uneducated experience with Death Wobble is lots of threads on message boards but I have yet to find one local SD owner who either has heard of it or experienced it. Doesn't mean it isn't real but at this point I would have to say the root cause is multiple components added that don't mesh well together. SD's are by far the most popular truck on the road in my area so I have asked several hundred owners to date. Yes I am that guy who will approach a complete stranger and ask him about his truck. I read enough on here that is scared the crap out of me too so I first went to my relatives who are diehard Ford guys and they looked at me like I had 3 heads. Then I spoke with as many others as I could find who all had never experienced it or ever heard of it.
My goal with the Fox stabilizer is to calm the little bit of steering wheel shimmy I get now after going to AT tires and different rims from stock along with the fact that I have already replaced the stock shocks all the way around the truck with Fox 2.0's. Unless something changes I won't ever own/drive a truck without Fox shocks. They are that much better than anything else on the market. I've been told the Fox stabilizer will clean that right up and I believe it based on the improvement in ride with the shocks.
