Roadmaster 1139-147 Rear Anti-Sway Bar Kit For Ford E450

Both Stock And Custom Anti-Sway Bars Are Designed As A Link Between The Suspension And The Frame, And Both Use The Weight Of The Axle As A Brace Against The Chassis, So That Pressure To One Side Of The Motorhome (By Weight Shift, Wind, Or Passing Trucks) Is Countered By The Bar. An Rss Anti-Sway Bar, However, Is Built To Offer Significantly More Resistance To Sway. Rss Anti-Sway Bars Have A Thicker Diameter Than Stock Bars – Often, A Quarter To Three-Eighths Of An Inch More. Each Incremental Increase In Diameter Has An Exponential Effect On Performance – On Average, Torsional Roll Stiffness Is Increased By 30 Percent With Every Eighth-Of-An-Inch Increase In Diameter. In Plain English, Rss Anti-Sway Bars Offer Up To 90 Percent More Resistance To Sway. A Remarkable Improvement In Stability And Cornering Control Is Just A Few Bolts Away. Anti-Sway Bars From Roadmaster Suspension Solutions Deliver A ‘Wow!’ Difference In Control You’Ll Notice The First Time You Turn The Wheel.
