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.

  • Roadmaster End Link Kit For A 2006 Ford F-250 Super Duty
    I took a look at what we have for your 2006 Ford F-250, and I was able to find the End Link Kit for Roadmaster Rear Anti-Sway Bar for Pickup Trucks # RM-590170-00. These are the same end links used in the Roadmaster Rear Anti-Sway Bar # RM-1139-170 according to the instruction manual. This kit includes the two end links, along with the necessary hardware for installation.

  • Recommended Suspension Enhancements To Improve Unloaded Ride Quality on 2006 Ford F-250
    I do have some recommendations to help improve your overall ride quality when driving unloaded, but I would not recommend the RoadActive Suspension # RAS3611 as it will add additional support to the springs when the truck is unloaded. Instead I recommend adding the Front # SSF-111-40 and Rear # SSR-114-47 SumoSprings to your 2006 Ford F-250. These are proportional springs which are designed to have a a small air gap or only just start to make contact when unloaded. That will help the truck...

    The Roadmaster Rear Anti-Sway Bar # RM-1139-170 you found will fit your 2007 Ford F-250 which did not come with a factory sway bar. Roadmaster makes my favorite sway bars as they made in the USA from quality steel.
