From Carli Suspension
Like any other spring native to a stock Super Duty, the factory Sway Bar is nearly immobile. Conversely, it’s the most neglected spring on the vehicle as people fail to look past the front coils and rear leaf springs when looking to “soften” the factory ride. Well, the factory sway bar is essentially a brace locking the axle to the frame. What does this mean? What you hit with one tire is immediately transferred to the other tire and into the frame causing a high frequency reverberation/chatter felt in the cab.
So where does the factory sway bar come in? The Factory sway bar is setup to load the truck to it’s MAX legal weight and haul it safely – for this application, there’s no better bar. Throw a 3,500 pound cab-over camper in the bed and hit some remote mountain roads en-route to your destination and it all starts to make sense why Ford did what they did.
