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.

Video Transcript for Complete Breakdown of the Roadmaster Rear Anti-Sway Bar-RM-1209-113

Hello everybody, this is Jeff at etrailer.com. Today we're gonna take a look at this Roadmaster rear anti-sway bar. Now this is a custom fit part. This is designed to fit the 1991 to 2002 Freightliner FL-series, the FL70 EV Type1 that has the airliner suspension and the six inch by four inch U-bolt pattern. And it will also fit the 2003 to 2016 Freightliner m2 EV Type1, also with the airliner suspension and the six inch by four inch U-bolt pattern. Now, one note I do wanna mention this will not fit models that have the optional center fuel tank.

Now this will minimize side-to-side movement, improves overall stability of your vehicle. This'll let you execute turns and quick maneuvers with confidence. It'll allow for a nice level ride, even on irregular surfaces and it helps reduce driver fatigue 'cause it'll minimize the effort that's required to keep your vehicle in line. This does diminish any effects of cross winds, passing motorists, shifting cargo. It is designed to fit your vehicle and work in conjunction with its suspension system.

Basically this will attach to the rear axle and to the chassis and it uses the weight of that axle to brace the frame as it shifts and turns. And it is also engineered to avoid interference with most of your popular aftermarket add-ons and accessories. Now this is made with polyurethane bushings, going to zoom in and just show you a few of them. There's some of your polyurethane bushings instead of the standard rubber variety, gives you a lot longer-lasting system. The polyurethane is more durable and resistant to damage that can be caused by oil, gas, and ozone, and of course less wear'll mean less give in the system and better support.

The bar itself right here is constructed of a thick 4140 chromoly steel for superior strength. The diameter on this bar is 1 1/2 inches and this does include everything shown here on the table. It includes the heavy gauge mounting brackets, all the hardware you need, comes with a nice set of easy-to-follow instructions and they even give you a little tub of bushing lubricant that you want to apply to the bushings when you go to install 'em. This part is made in the USA. But that should do it for the review on the Roadmaster rear anti-sway bar..

  • Anti-Sway Bar and Steering Stabilizer for a 2012 Freightliner M2
    We have different sway bar options depending on how your 2012 Freightlinter M2 is equipped. The sway bars for this vehicle will fit 2 different Class A motor home models and 3 different EV Type 1 vehicles (emergency vehicles). Starting with Class A models, if it has an 8,000 pound rear axle you would use # RM-1209-116 but it won't fit if the vehicle has the auxiliary cooling package. If the vehicle is an EV Type 1 with airliner air suspension with chains and 5 x 4 u-bolt pattern you would...

  • Is The Shackle For The Roadmaster Rear Anti-Sway Bar Available For A 2005 Freightliner M2?
    The Replacement 12-5/8' Shackle for Roadmaster Anti-Sway Bar Kits # RM-B404 that you mention is the correct replacement for the Roadmaster Front Anti-Sway Bar Kits 1169-110, 1169-208, and 1169-212, as well as the rear anti-sway bar kit RM-1139-149. These kits are not the correct kits for your 2005 Freightliner M2, and in turn, the shackle mentioned won't be compatible with your vehicle. Unfortunately, the shackle in the rear anti-sway bar kit like the Roadmaster Rear Anti-Sway Bar #...

  • Which Rear Anti-Sway Bar for a 2015 Freightliner M2 Sport Chassis
    I checked with my contact over at Roadmaster and he tells me that you'll want to check the U bolt pattern on your suspension in order to make sure you get the correct sway bar, since there could be two potential fits for your 2015 Freightliner M2 Sport Chassis. If you've got a 5"x4" bolt pattern, then the # RM-1209-106 will work for you. If you've got the 6"x4" bolt pattern then you'll want to use the # RM-1209-113. This would be the only way to determine the correct fitment for this chassis.
