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.

  • Will Rear Anti-Sway Bar Fit a 2023 Ram 2500 with Air Spring Kit
    Hey Gregory, thanks for reaching out! The fitment of the Roadmaster Rear Anti-Sway Bar # RM73FR on your 2023 Ram 2500 actually has more to do with whether or not you have a factory swaybar. This one will work if you DON'T have the factory swaybar, but if you DO have the swaybar then you'll need the Anti-Sway Bar # RM34GR instead. Both options work just fine with the air spring kit on your truck.

  • Is Timbren Or SumoSprings The Better Option For Occasional Towing?
    Hi Paul! Since you said occasional towing, I am going to steer you away from the Timbren option. They can be pretty rough and you will definitely feel it when you are not towing. If you had a constant load, it would have been an option, but I don't think you will be happy with them. The SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-312-54 will be the much better choice. Yes, it does have a lower capacity than the Timbrens, but I believe they are much better suited to your needs....

  • Recommended Rear Anti-Sway Bar for a 2021 Ram 3500 Dually
    Hey John. No, you will not have to remove your TorkLift SuperHitch item # TLD1111-30 or any tie downs to install the Hellwig Big Wig Rear Anti-Sway Bar item # HE24MR on your 2021 Ram 3500. Does your Ram 3500 have a diesel engine? The Hellwig Big Wig Rear Anti-Sway Bar item # HE24MR will only work on the diesel models of the 2024 Ram 3500. It is not compatible with the 6.4 Hemi model. You would need the Roadmaster Rear Anti-Sway Bar item # RM73FR, which has a different orientation and mounting...

  • Best Rear Sway Bar For 2022 Ram 3500 Laramie Mega Cab 6.4 Hemi
    Hello. We do have a rear sway bar that will fit your 2022 Ram 3500 Laramie mega cab short bed 6.4 Hemi 4x4, but the # HE24MR you mentioned will only fit Diesel models and is not compatible with the 6.4 Hemi. Instead, what we recommend for your truck is the Roadmaster # RM73FR. This is compatible with both gas and Diesel models. Just keep in mind this is intended only for vehicles without a factory sway bar.

  • Rear Sway Bar For A 2026 Ram 3500 Dually With 4 Wheel Drive And 6.4L Gas Engine
    Hi Jerry! We do indeed have a rear sway bar for your 2026 Ram 3500 Dually 4 wheel drive with the 6.4 gas engine. There are actually two options and I have them listed below: Without Factory Sway Bar: Roadmaster Rear Anti-Sway Bar - 1-1/2" Diameter # RM73FR With Factory Sway Bar: Roadmaster Front Anti-Sway Bar - 1-5/8" Diameter # RM47VR It doesn't look like Hellwig has one for the gas engine 3500 as of yet. Roadmaster makes very good sway bars though, so either of these would work very...

  • What Replacement Bushings Go With The Roadmaster Anti-Sway Bar RM73FR
    Hello Ed, thanks for reaching out. I pulled up the parts breakdown for the # RM73FR sway bar, and it looks like the correct replacement bushings are parts 205220-20 and 205223-50. We carry the 205223-50 bushing as part # RM74ZR, but sadly we do not carry the 205220-20 for some reason. If you get ahold of Roadmaster directly they should be able to provide one for you. Leave a reply below and let me know if there is anything else I can do to help.

  • Best Anti Sway Bar Option For My 2024 Ram 3500?
    Hey William, We have a great option for a rear anti sway bar for your 2024 Ram 3500. Both the 2 wheel and 4 wheel drive models use the same anti sway bar so I recommend the Roadmaster # RM73FR. I will add with these since the Ram's do not come with a factory sway bar, drilling into the frame is required to install this on your vehicle. Are you towing with that truck or do you have more of a truck bed camper setup?

  • Best Rear Anti-Sway Bar for 2019 Ram 2500
    Hi Steve; assuming you have a factory sway bar then yes, the Roadmaster Rear Anti-Sway Bar # RM34GR is the best option. The 1-1/2" diameter is the largest available so it will add the most stability. If you do not have a factory sway bar you need the # RM73FR instead.

  • How to Get the DeeZee Custom-Fit Truck Bed Mat to Lie Flat After Install
    Hey Norman welcome back! Heats going to work but for now you can lie something heavy on the end of the DeeZee Custom-Fit Truck Bed Mat item # DZ28GJ to speed up the process. Those come rolled up so it's still got that memory to it from being stored that way as soon as it was manufactured. You could also remove it and lie it upside down with something heavy on that tailgate end too. Happy to hear you're enjoying the bed mat. What do you use your truck bed for?

  • Will the Roadmaster Rear Anti-Sway Bar # RM73FR Fit a 2021 Ram 3500 Crew Cab 4WD Truck
    Yes, the Roadmaster Rear Anti-Sway Bar # RM73FR will fit your 2021 Ram 3500. Anything listed on this site as having a confirmed fit means it has either been installed by an etrailer Tech on site or we have been provided confirmation by the vendor that it has been installed successfully, on that year, make and model, at their location. We also have the Roadmaster Front Anti-Sway Bar # RM47VR as a confirmed fit for the front.

    No, it won't and it's because of the exhaust. The Hellwig Big Wig Rear Anti-Sway Bar item # HE24MR will only work on the diesel models of the 2024 Ram 3500. It is not compatible with your 6.4 Hemi model. The Roadmaster Rear Anti-Sway Bar item # RM73FR has a different orientation and mounting hardware so it is compatible with both the gas and diesel engine models.

  • Can TorkLift StableLoad be Used with Air Bags and RAS on 2021 Ram 3500
    The TorkLift StableLoad Suspension Upgrade w Quick-Disconnect # TLA7310S should fit just fine with the Air Lift air bag kit and RAS on your 2021 Ram 3500. My concern though is that you've either already worn out the factory suspension on your truck, you have something loaded well off-balanced, or you're overloading your pickup. It could also be a combination of the 3 as well. Normally air bags OR the RAS alone are enough to handle standard loads which is why I'm concerned you're using...

    We have the TorkLift Camper Tie-Downs Front # TLD2142 and Rear # TLD3112 for your 2023 Ram 3500 Crew Cab long bed dually with the factory running boards. You may need the Anchor Relocation Kit # TLA7004 if your slide in camper is less than 90" from the front slide in portion to the rear anchor points.

  • Do I Need Front And Rear Anti-Sway Bars On My 2019 RAM 2500 With Factory Air Suspension.
    Having both Anti-sway bars will help but you may only need the rear one. The Roadmaster Rear Anti-Sway Bar # RM73FR will be able to give you the performance you need with hauling a truck camper. Having the Roadmaster Front Anti-Sway Bar # RM47VR installed will help to and give you better performance but it will not be a massive increase.

    We don't carry Hellwig products so I can't speak for them, but the Roadmaster Rear Anti-Sway Bar # RM73FR will not interfere with your Torklift Super Hitch Magnum 30k D1111-30 or the Air Lift LoadLifter 7500 XL Air Helper Springs - Rear Axle # AL57531 on your 2021 Ram 3500.

  • Roadmaster Anti-Sway Bar and Level of Installation Difficulty on a 2022 Ram 3500 w/ Air Suspension
    If you were to trade up the the 2022 Ram 3500 with air suspension then the Roadmaster Rear Anti-Sway Bar # RM73FR would be the correct sway bar for that truck. This sway bar would be an installation of similar difficulty as the sway bar on your 2021 Ram 3500, as it would also still require you to drill into the frame for the bushing clamp hole.

  • How Do I Minimize Body Roll On 2020 Ram 3500 While Towing 5th Wheel
    Yes, the Timbren Rear Suspension Enhancement System, # T94VR will enhance your current suspension reducing the body roll you are currently experiencing. With the Timbren Suspension Enhancement System, each hollow rubber spring works independently to support the driver's or passenger's side of the vehicle. Each spring is activated when it is needed, so body roll is greatly reduced. This is a great option for the price. I suggest you consider the Roadmaster Rear Anti-Sway Bar, # RM73FR....

  • Is An Anti-Sway Bar Recommended For A 1998 Dodge Ram 2500 Hauling A 2000 Lance 1010 Truck Bed Camper
    Yes, adding a rear anti-sway bar on your 1998 Dodge Ram 2500 will make a major difference in your vehicle's handling while hauling your truck bed camper. Truck bed campers are very top heavy and can cause side-to-side sway so an anti-sway bar will help keep you upright on the road. For a 1998 Dodge Ram 2500 you would need the Roadmaster Rear Anti-Sway Bar # RM-1129-122.

  • Recommended Front and Rear Sway Bars for a 2019 Ram 2500
    Rene, you unfortunately are not going to be able to use both air bags and SumoSprings like # SS68RR at the same time. The air bags fit inside the coil springs on the bag so there would not be room to also have the SumoSprings. Even if you were able to use the two at the same time, you'd have an unbelievably stiff ride that it would actually have negative effects. You could upgrade your rear anti-sway bar and add one in the front and that would definitely help keep you stable on the highway....
