The only reason you will get death wobble is if you set it too low. I am sure if you have a convo with Owl or Agile etc prior to buying they will happily refund you if you have an issue that cannot be attributed elsewhere.Having experienced the Dodge death wobble on my 1996 Dodge ram 2500 I can tell you the track bars are terrible and way underbuilt. I replaced mine years ago with a heavy duty track bar and never had a problem again. I am hesitant to replace the overly stiff factory steering stabilizer to improve the steering that I don't really have a problem with because I have heard a few reports of death wobble after the change.
I hope you will give it a shot and report back here. I think there has been a lot of circumstantial issues with some people install that has lead to a couple bad reviews. Plus the new designed bracket is much more appropriate on the FOX. The King looks like it just drops right in as well.
