Benefits of an Anti-Sway System

The Roadmaster anti-sway bar does for side-to-side movement what a good pair of shocks does for up-and-down motion. You will notice a marked improvement in your vehicle's stability as the bar works to balance weight transfer and reduce body roll. The anti-sway bar acts as a link between your vehicle's frame and its rear axle, using the axle as a brace to more effectively balance the shifting weight of your vehicle as you maneuver it. Lubricated bushings allow just enough pivot and rotation to compensate for the pressure placed on one side of your vehicle when it goes into sudden maneuvers, hits crosswinds or encounters shifting weights.


Roadmaster Anti-Sway Polyurethane Bushings

Superior Construction

The Roadmaster anti-sway bar is made of 4140 chromoly, a chromium and molybdenum steel alloy. This type of steel is considerably harder and stronger than the standard 1020 steel that is typically used in anti-sway applications. In addition, the larger diameter of the bar increases its torsional roll stiffness. The result is a bar that is not only stronger than the competition, but also nearly 30 percent better at resisting sway. The polyurethane bushings and grommets used at the attachment points are durable yet flexible, ensuring that the system is neither so rigid nor so malleable that it becomes ineffective.

Video Transcript for A Closer Look at the Roadmaster Rear Anti-Sway Bar

Speaker 1: Today we're gonna be taking a look at Roadmaster's Line of Rear Anti-Sway Bars for motorhomes. You want to refer to our fit guide to find the appropriate sway bar for your vehicle.The large size and heavy weight associated with motorhomes can cause drastic amounts of sway when driving down the road. To help create a safer ride, and reduce driver fatigue, we can minimize the sway by adding an additional rear sway bar. So when making basic maneuvers or sharp turns, you'll minimize the risk of a rollover.Also, when driving on windy days, on uneven pavement, you can get a sway affect going back and forth, and you'll have to compensate for that with the steering wheel to maintain and safe, straight path.This additional bar will help reduce that amount of sway, making it easier to maintain control of your vehicle and reduce vehicle fatigue, 'cause you're not having to compensate as much.The Polyurethane Bushings will help dampen road vibrations, and additionally stand up to corrosive road oils, salts, and UV rays. The bar is made up of 4140 chrome steel, where most factory bars are only made of a lower strength, 1020 steel.And to maximize your reduction of sway, Roadmaster recommends you also get a front anti-sway bar. Using our fit guide at etrailer.com you can pick out the appropriate rear and front end anti-sway bars for your motorhome.Now we'll take our anti-sway bars out on our test course.

When we go into our alternating bumps, you can instantly feel a difference in the amount of sway. It's a lot more stable side to side then it was before, making it much easier to maintain control of the steering wheel.And then we'll head onto our straight bumps. When we hit those, there's a definite difference in how much forward and back movement than we had before. It's definitely a more comfortable ride than what we had. And again, it's easier to maintain control of the steering wheel.And now we'll head onto our slalom where we can really test our the sway capabilities.

So if we have some evasive maneuvers, how our motorhome would react. And it's a massive difference. When turning, there's hardly any sway. I feel much more confidence taking sharp, evasive turns.Our customer David S purchased both front and rear Roadmaster anti-sway bars, and had this to say."I installed front and rear sway bars on my 2006 Itasca Suncruiser after making a winter trip to Florida from Ohio. We made a return trip this past winter, through the smoky mountains etcetera.

The improvement in handling was so noticeable, my wife noticed it from the passenger seat. I highly recommend both of these products. I have a workhorse w24 chassis. Crosswinds and semi-push was very minimal. One handed driving in most situations in the norm now, and driver fatigue was minimal.

Driving the coach is much more enjoyable."And that completes our look at Roadmaster's line of rear anti-sway bars for motorhomes.

  • Comparing RoadActive Suspension Kit and Sway Bar For 2006 Chevrolet Express Van
    For your 2006 Chevrolet Express 12-Passenger Van I recommend the RoadActive Suspension Custom Leaf Spring Enhancement Kit # RAS2611-V which gives you 2000lbs of load leveling support when you have the van full of cargo and passengers, but also eliminates axle wrap and does a great job of minimizing body roll and sway when you get a side wind. The Roadmaster Rear Anti-Sway Bar and Axle Mounting Kit # RM-1109-150-00 would only help with sway while not changing the ride quality of the van,...

  • Compatible Rear Anti-Sway Bar For A 1999 Chevy Roadtrek 200 Popular

The brackets will attach to the outside of the frame, as you can see in the attached picture from the installation manual. The end links are 12.19 inches from the center of the eyelet to the end of the threads so with it being bolted to the outside of the frame and that length down...

  • Recommended Rear Anti Sway Bar For A 2004 Chevy Express 3500 Class C Motorhome
    Both the # RM-1109-175-00 and the # RM-1109-150-00 sway bars are a confirmed fit for your 2004 Chevy Express 3500 Class C Motorhome. The # RM-1109-150-00 is 1-3/8 inch in diameter with a more shallow bump to fit around the rear differential and and the # RM-1109-175-00 is 1-1/2 inch in diameter with a larger bump to clear the rear differential. Because of the thickness and clearance space the # RM-1109-175-00 is the better option for your motorhome.

  • Anti-Sway Bars For 2008 Fleetwood Jamboree Sport Motorhome
    With the extensive sway you are experiencing driving your 2008 Fleetwood Jamboree Sport, the best thing you can do is add an aftermarket rear anti-sway bar because it acts as a brace between the frame of your motorhome, and is constructed with higher-strength, thicker steel than OEM sway bars. This means it has much higher roll stiffness to combat sway - the higher the roll stiffness the better sway control - and its placement at the rear of the vehicle allows for the greatest improvement...
