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.

  • Availability Of Front And Rear Sway Bars For 2001 Dodge Ram 3500 Dually
    Hello Derek, thanks for reaching out. We do have a rear sway bar for your 2001 Dodge Ram 3500 dually, but I am sorry to say we do not offer a front sway bar option at this time. For the rear bar, here is what I recommend: - Roadmaster Rear Anti-Sway Bar - 1-1/4" Diameter # RM-1129-122

  • Will Upgrading Rear Anti-Sway Bar Help Reduce Body Roll on a 1999 Dodge Ram Pickup
    Upgrading the rear factory anti-sway bar with # RM-1129-122 will help reduce side to side body roll. This bar fits 2500 and 3500 series 4x4s only. Other option to reduce body roll is to install some suspension helper springs. If you have a 4x4 with standard height (no factory or aftermarket lift) I recommend # TDR1525H4 which will fit a 1500 or 2500 but not a 3500. For a 3500 use # TDR3500 for a 4x4 or # TDR3500B for 2-wheel drive models. For a 1500 with standard height and 2-wheel drive...

  • 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.

  • Best Suspension Upgrade for a 1999 Dodge Ram 2500 with Arctic Fox Truck Bed Camper
    For your 1999 Dodge Ram 2500, I recommend replacing the rear sway bar first since the majority of the added weight is placed on the rear suspension. Adding a front or rear sway bar will not affect the ride quality. The Firestone airbags you have work great for helping to evenly distribute the added weight but will not compare with an upgraded sway control bar as far as reduced body roll goes. I recommend taking a look at the Roadmaster Rear Anti-Sway Bar part # RM-1129-122. The Roadmaster...

  • Rear Axle Anti-Sway Bar for 1999 Dodge Ram 3500 Extended Cab Dually
    The Roadmaster Rear Axle Anti-Sway Bar # RM-1129-122 that you referenced is a correct fit for the 1999 Dodge Ram 3500 extended cab 4-wheel-drive dually. I verified the fit of this kit on your truck with my technical contact at Roadmaster. This will not fit 2WD versions. This anti-sway bar installs without drilling since it replaces the factory sway bar.

  • Rear Sway Bar Recommendation for 1999 Dodge Ram 2500 with Camper
    A rear sway bar will help greatly with the body roll you are experiencing with your 1999 Dodge Ram 2500. For that you'd want the Roadmaster sway bar part # RM-1129-122 which is a confirmed fit and designed for your situation.

  • Does Install of Roadmaster Swaybar on 2002 Dodge Ram 2500 Require Drilling
    The Roadmaster rear sway bar part # RM-1129-122 is a confirmed fit for your 2001 Dodge Ram 2500 4WD, it replaces the factory sway bar, uses factory mount locations and does not require drilling. It wasn't tested with aftermarket 4 inch exhaust but looking at how the exhaust routes on your vehicle and the location of this I do not believe it would be an issue. Removing the tank bracket is sometimes required to access the bolt. It's not as difficult or challenging as it may sound like though.
