  • Custom-designed for a specific chassis and suspension system
  • Easy, bolt-on installation
  • Each kit comes complete with heavy-gauge mounting hardware, easy-to-follow instructions, and the bushing lubricant
  • Larger diameter, powder-coated 4140 chromoly steel bars and heavy-duty polyurethane bushings ensure maximum support and more durability than factory bars


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.

I have a RV (Ford E450 Base) and it used to sway a lot when bug rip passed by my RV. After installed it, it improved a lots, and the sway situation just felt like just drive a sedn.

Quality bar. It has a very hard coating and looks great, like a work of art. Too bad it is hidden out of sight. It took me about an hour to install it. Save about $500 installing it myself. I did call around but no one liked installing customer supplied parts -- greed, I think -- and if they would do the job they could not get to it for several months -- just another way of saying, no. And forget about asking the Dealership of these Ford Chassis -- as soon as the work, Motorhome, is mentioned you are politely told, "We do not work on Motorhomes". FINE, thank you everyone for saving me some money -- and for finding out this was not a job beyond anyone who can turn a wrench. Yes, you have to crawl around but if I, an 80-year-old man in reasonable shape can do it, well, so can you. I installed the front sway bar as well, and a set of Sumosprings. The Roadmaster Sway bars really improved the sway effect you get when a cross wind hits or pulling in and out of sloped driveways. Yes, there is still some sway, but the whipping action that follows, which is the part of the sway that tosses the dishes around and anything not tied down goes flying. I checks the sway in its comeback and actually makes it feel like you might be in control. These should be stock on all E350 and E450 chassis used for any conversion to a motorhome. Until then, we have to install our own. The upside is that if the Manufacture were to install these, they would figure out how to cut corners to save a dolloar but when you do it yourself you can give it the grade A treatment. Yes, I would do it again and I am very, very pleased with the quality of the Roadmaster kits.

Great improvement over stock. Helps when you pass the big rigs so you don't move all over the road. Install was very straightforward.
