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.

  • Difference In OEM And Aftermarket Anti Sway Bars / Recommended Fit For A 2016 Sunseeker 2860 DS
    Aftermarket sway bars are stiffer than OEM sway bars and many come with polyurethane or hybrid bushings. Anti-sway bars are mainly to reduce body roll while cornering while the steering stabilizer's primary function is to dampen or stabilize the side to side movement of the wheels in much the same way shock absorbers limiting excessive suspension movement & oscillation. Both will offer better handling and less body roll for a smoother and safer ride. The correct fitting anti-sway bars...

The SumoSprings do help some with sway and body roll, but are more designed to support your suspension.
