Roadmaster Anti-Sway Bar Installed

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.

  • Rear Anti-Sway Bar For A 2013 Chevy Express Van
    Since the Roadmaster Rear Anti-Sway Bar Item # RM-1109-173 is meant for as a stock sway bar replacement we don't carry the brackets but we do have a confirmed fitting sway bar with the brackets together - Roadmaster Rear Anti-Sway Bar Item # RM-1109-175.

  • Could Roadmaster Sway Bar # RM-1109-175 Fit 2015 Roadtrek 190 with Generator
    As long as the generator allowed the stock sway bar of your 2015 Roadtrek 190 the Roadmaster Sway Bar part # RM-1109-175 would also fit. I looked up pictures and it looks like there shouldn't be a problem as I was able to see the generator and the sway bar both fit at the same time.

  • Suspension Enhancement Recommendation for a 2007 Chevy Express Van to Fight Death Wobble.
    I spoke to my contact at Roadmaster and he informed me that to combat your death wobble they recommend you first start with a rear anti-sway bar like the Roadmaster Rear Anti-Sway Bar # RM-1109-175. He said that should fix your problem, but if not you next would want to get a Roadmaster Reflex Steering Stabilizer # RM-RBK17-RSSC that you referenced. My contact at Roadmaster did not recommend removing the coil either.

  • Suspension Upgrade for 2014 Class C Motorhome on Chevrolet 4500 Chassis To Reduce Sway From Wind
    Hi Joe; the best upgrade you can make is to add anti-sway bars like the # RM-1109-175 you looked at. This is a confirmed fit for your 2014 Class C motorhome. The rear is the most important addition but the best option is to also add a front anti-sway bar # RM-1109-149 so the two work together to keep you stable. If you really want to go all out you can also add the RM Reflex Steering Stabilizer # RM-RBK23-RSSC. The stabilizer returns your vehicle to center which helps you keep control...

  • Recommended Rear Anti-Sway Bar for 2007 Chevy Express Class C Chassis
    I checked with Roadmaster and did verify that the Roadmaster Rear Anti-Sway Bar # RM-1109-175-00 is confirmed to fit your 2007 Chevy Express Class C chassis. The axle mounting kit (which is included with this part number) is indeed to allow for an attachment point and base on the axle. My contact did say that if the chassis was built before 6/2006 the kit should be needed. Take a look at the installation video I attached so you can see exactly how the bracket kit is used. If you can send...

  • Fit of Roadmaster Swaybar RM-1109-175 on 2013 Chevy Express Van Class C RV
    The fit of a Sway Bar like Roadmaster RM-1109-175 depends on the specific version of your base Chevy Express Van. For instance, if you have the 2500/3500 Class C Cutaway you can use part # RM-1109-175. This also fits other versions such as the 2500/3500 Class C Van. Unless the OEM exhaust has been modified to allow installation of Thor RV components you should have no issue installing this on your RV. You can check with Thor using your VIN to confirm which base chassis you have and then...

  • Rear Anti-Sway Bar Fit For 2021 Thor Freedom Elite Motorhome on Chevy 3500 Cutaway Chassis
    I checked with Roadmaster for you, and verified that there is a rear anti-sway bar that fits your 2021 Thor Freedom Elite on a Chevy 3500 cutaway chassis, though there is not a front anti-sway bar that fits. The correct part number for the rear bar is the following: - Roadmaster Rear Anti-Sway Bar # RM-1109-175 A rear anti-sway bar like # RM-1109-175 is the best way to enhance the ride of your motorhome because it acts as a brace between the frame of your motorhome, and is constructed...

  • Rear Sway Bar Recommendation for a 2014 Forest River Sunseeker on a Class C Chevy 4500 Chassis
    Yes, for your 2014 Forest River Sunseeker built on a 4500 Class C Chevy Chassis you would want the rear sway bar part # RM-1109-175. This is a 1-1/2 inch thick sway bar confirmed to fit your vehicle. The part # RM-1109-150 will also fit your RV but since it's a slightly thinner bar it wouldn't offer as much stability. The trade off between thinner vs. thicker is that thicker is more stable but may cause a slightly harsher ride if the vehicle is on the lighter side. For the size of your...

    For your 2010 RoadTrek 190, I recommend the Roadmaster Rear Anti-Sway Bar for Trucks and Motor Homes # RM-1109-175 which is a confirmed fit for your vehicle and should not interfere with your generator. I've attached an installation video to assist, but it does not have the generator in that location. I also recommend the front sway bar # RM-1109-149 which is also confirmed to fit. This combination will work very well for your vehicle and will minimize sway and driver fatigue by improving...

  • Anti-Sway Bar for a 2002 Chevy 3500 Cutaway RV
    There are several items to reduce sway, see link, that will fit your 2002 Chevy Cutaway 3500. If the existing bar has a 1-1/2 inch diameter then you can use # RM-1109-175 that you have referenced. If the chassis was built before June 2007, you will also need bracket kit # RM-590061-00. If the existing bar has a 1-3/8 inch diameter then you would use # RM-1109-150 and the same bracket kit listed above # RM-590061-00 for chassis built before June 2007.

  • Rear Anti-Sway Bar for Class C RV Built on a 2001 Chevy 3500 Express Van Chassis
    It is most likely a Class C. For a rear anti-sway bar you would use # RM-1109-150. Since it is a 2001 Chevy 3500 chassis you will need an additional axle mounting bracket, # RM-590061-00, to complete the installation. I have included a link to the sway bar instructions for you. If it is rated as a Class B there are no confirmed fits listed.

  • Rear Sway Bar for Small School Bus on 2002 Chevy Express 3500 Cut-Away Chassis
    I spoke with my engineering contact at Roadmaster, who tells me that the # RM-1109-175 anti-sway bar is the correct choice for your Micro Bird Bus on a 2005 Chevy Express cutaway chassis. Because the vehicle was built before 2007, the # RM-590061-00 mounting kit will be needed.

  • Will Adding a Steering Stabilizer Stop the Death Wobble on a 2011 Chevy Express 2500 Conversion Van
    The first thing to look at is what is the underlying cause of the death wobble on your 2011 Chevy Express Conversion Van? Some vehicles just do it with no mechanical reason why. Others may be in need of some sort of repair or wheel balancing/alignment. Basically if the root cause is not addressed there is no guarantee that a steering stabilizer or other product would solve the problem. Steering stabilizer # RM-RBK17-RSSC does fit your van but the product that will make the greatest improvement...

  • Troubleshooting Noise Coming From the Rear of Vehicle When Turning Corners
    Sounds like the bushings that connect the sway bar to the vehicle's frame may be worn out. With the bushing worn out there will be extra slop and movement in the connection causing the noise when making your turns. I recommend replacing the sway bar and bushings. With worn out bushings, the bar may have started to wear on the busing ends and just replacing bushings may only put a band aid on the problem. Our sway bars from Roadmaster come compete with new bushings and all the hardware...
