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 Fitment for a 2WD 2019 Ram 1500 Classic
    Hey Kevin, The only rear anti-sway bar that fits your 2WD 2019 Ram 1500 Classic is the Hellwig Adjustable Rear Anti-Sway Bar # HE29GR. If you don't already have factory end links then you also need the kit # HE74SR to install this anti-sway bar. The Roadmaster kit # RM-1129-135 you're asking about is only compatible with the 4WD model, so it won't work for your truck.

  • Comparing Roadmaster and Hellwig Rear Sway Bars For a 2009 Dodge Ram 1500
    Personally, when I have a choice between Roadmaster # RM-1129-135 and Hellwig # HE29GR I choose Roadmaster. I have used their sway bars for several years and have never had an issue. You are correct that the Hellwig is a solid 4140 steel and the Roadmaster is also a solid 4140 steel so with the larger 1-1/8" diameter it is going to be stronger than the 7/8" Hellwig option.

  • How to Reduce Sway on a 2016 Ram 2500 with a Lance 820 Truck Camper
    With how the Firestone Air Helper Springs, like the # F2706, will attach to the frame, you would not be able to install a Timbren # TDR2500D as well. Both of these options will mount in the same place, unfortunately. That being said, the # TDR2500D may be better for your situation than the air bags. I do typically suggest air bags as they are fully adjustable, but they can be a little lacking when under constant heavy load and are not as good at handling sway problems. Another upgrade...

  • Rear Suspension Enhancement Springs For A 2022 RAM 2500 With Factory Air Suspension
    Yes, The Timbren Rear Suspension Enhancement System # TDR2500D will fit your 2022 RAM 2500 with factory air suspension. The Roadmaster Sway Bar # RM-1129-135 will not. The Timbrens will give you up to an additional 8,600 pounds of suspension support. These springs act like shock absorbers, taking the brunt of bumps and rough roads. Using these springs will not exceed the vehicle's weight-carrying capacity. I attached an installation video link below.

  • Recommended Rear Anti-Sway Bar for 2016 Ram 1500
    The best and only anti-sway bar we offer for a 2016 Ram 1500 is the Roadmaster Rear Anti-Sway Bar part # RM-1129-135 which replaces the factory rear anti-sway bar so there will be no fit issues. The larger diameter bar will do a better job of improving overall stability of your vehicle. It also offers a simple bolt-on installation.

  • Are Upgraded End Links Needed For Roadmaster Rear Anti-Sway Bar on 2021 Ram 1500 Classic
    Upgraded end links are not something that are necessary for the Roadmaster Rear Anti-Sway Bar # RM-1129-135. It does come with end links that you'll use to replace the factory end links on your 2021 Ram 1500 Classic, and like the anti-sway bar, these are strong, as are the heavy-duty polyurethane bushings. If you feel like you need to upgrade them after some time you can, but the end links for the # RM-1129-135 will absolutely do the job that is intended. In regards to the fuel tank or...

  • How To Eliminate Sway On a 2018 Ram 2500 With Truck Bed Camper
    The most beneficial component that you can add/upgrade to help eliminate sway is an anti-sway bar, the Roadmaster Rear Anti-Sway Bar part # RM-1129-135 in particular. The Roadmaster Rear Anti-Sway Bar will replace your factory sway bar and because it has a larger overall diameter will do a better job of helping to limit the sway you are experiencing with your truck bed camper at highway speed. The Roadmaster Rear Anti-Sway Bar also comes with polyurethane bushings that are more durable...

    The Roadmaster Rear Anti-Sway Bar # RM-1129-135 will replace your factory sway bar on your 2017 Ram 2500 with a stronger bar and polyurethane bushings. If your only issue is sway this is what you need to help reduce sway. If you are also dealing with rear suspension sag the SumoSprings Rebel Custom Helper Springs # SS27GR will reduce sag and provide additional stability to reduce sway. These can be used with the sway bar listed above for increased sway reduction if you do not feel there...

  • Best Anti-Sway Bar For 2021 Ram 1500 Classic 4WD
    The best anti-sway bar for your 2021 Ram 1500 Classic 4WD is the Roadmaster option: - Roadmaster Rear Anti-Sway Bar # RM-1129-135 Reason for that is it is the thickest available at 1-1/8" diameter, which means it has higher roll stiffness to combat sway - the higher the roll stiffness the better sway control - and allows for the greatest improvement in overall handling.

  • Will the Roadmaster Rear Anti-Sway Bar #1129-135 Fit My 2021 Ram 1500
    I have an option for you if you are looking to enhance your suspension on your 2021 Ram 1500 but the Roadmaster Rear Anti-Sway Bar # RM-1129-135 will not be a fit. Roadmaster has not developed or confirmed an anti-sway bar for the 2019-2021 Dodge Ram 1500. The option I have for you depending on your needs is helper springs. These helper springs can be beneficial to you with support and added control with heavy loads. Depending on how much you are towing I have two recommendations. The...

  • 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....

  • Is There a Front Anti-Sway Bar for a 2017 Ram 1500
    I do have an option for you but we only offer an upgraded rear anti-sway bar for a 2017 Ram 1500, the Roadmaster Rear Anti-Sway Bar part # RM-1129-135 which like a front anti-sway bar will work great to reduce body roll and improve stability. The only type of suspension enhancements we offer for the front are the Timbren Front Suspension Enhancement System part # TDF15004B or similar which like a sway bar, can reduce side to side rocking but admittingly won't be quite as good as an anti-sway...

    The Roadmaster Rear Anti-Sway Bar # RM-1129-135 that fits your 2018 Ram 2500 with 4WD replaces the factory anti-sway bar, and just like the aftermarket anti-sway bars for motorhomes, they are an improved version of an anti-sway bar, made from 4140 chromoly steel which is a high-grade steel that means they are much stronger than standard steel. The anti-sway bar will be an upgrade but I also highly recommend adding air bags for additional suspension enhancement. The Firestone Ride-Rite...

  • Thickest Anti-Sway Bar For 2021 Ram 1500 Classic 4WD
    The thickest anti-sway bar for your 2021 Ram 1500 Classic 4WD is indeed the 1-1/8 inch thick Roadmaster: - Roadmaster Rear Anti-Sway Bar # RM-1129-135 We don't offer Moog so I can't offer any insight into that, but the # RM-1129-135 is the thickest available for your truck.

  • Will Anti-Sway Bar Fit 2016 Ram 1500 with Two-Wheel Drive
    We do have suspension enhancements that will be a great option for your 2016 Ram 1500, but I checked with Roadmaster and the Rear Anti-Sway Bar # RM-1129-135 will only fit four-wheel drive models. What I recommend instead is the SumoSprings Solo Custom Helper Springs - Rear Axle # SSR-307-40 which will fit your '16 Ram 1500 2WD and help reduce the amount of body roll because the work independently by compressing when making a sharp turn, for example. The SumoSprings are also extremely...

  • Rear Anti-Sway Bar for 2015 Ram 1500 4x4
    Hello Lee; for a rear anti-sway bar on your 2015 Ram 1500 4x4 I recommend the Roadmaster. Their anti-sway bars are well constructed, reliable, and backed by a limited lifetime warranty. The 1-1/2" diameter and 1-3/8" diameter are actually designed for the Rebel so you can rule those out. That makes for an easy decision since the Roadmaster Rear Anti-Sway Bar - 1-1/8" Diameter # RM-1129-135 is the only option.

  • Does the Roadmaster Sway Bar # RM-1129-135 Require Drilling to Install

  • Will the Roadmaster Rear Anti-Sway Bar Help Reduce Sway on a 2012 Ram 1500
    Yes, the Roadmaster Rear Anti-Sway Bar # RM-1129-135 that you referenced will help reduce sway and help stabilize the vehicle, especially with the other suspension components that you are also upgrading. However, a properly loaded trailer is the best defense against trailer sway. You will want to make sure you have as much weight as far forward on the trailer as possible. Another option you have to fight sway is a weight distribution system. Weight distribution systems do what their...

If you're leaning towards something that is maintenance free and helps with the sway then go with the anti-sway bar. For something that offers more control and will help with rear sag then definitely go with an air bag kit. Let me know what you're looking to get out of...
