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. If you’ve ever hit a manhole cover on the driver’s side tire and felt a shake in the entire truck or you’ve ever entered an off-camber driveway and smacked your head on the window – you can thank the factory sway bar. Truth be told, it’s responsible for many of the small-bump compliance gripes thanks to immobility.
So where does the factory sway bar come in? These trucks are heavy pigs… Even being radius arms (MUCH better for sway control than a 4-Link), a bit of supporting spring rate plays a substantial roll in keeping the body roll in check and suspension composed. 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.
For everyone that’s not loaded to the GVWR daily, the Carli Torsion Sway Bar provides the final link lightening the last spring on the truck maximizing the ride quality of the Super Duty Platform. Keeping your factory bar limits comfort, removing it completely makes for questionable control when hauling or emergency maneuvering. After several revisions and years in development, the Carli Torsion Sway Bar Splits the Difference perfectly allowing a small amount of differentiation side to side before progressively engaging to add the needed control as leverage is applied. Rip corners in the dirt with surgical precision knowing there’s exactly enough rate to hold the body steady while cutting your line through the dirt. Hit the tarmac and enjoy the benefit of the lighter rate bar cruising around town with it’s on-road feel reminiscent of an independent front suspension – no more chassis reverberation on small bumps and let the suspension dance in the level cab while hitting off-camber driveways
