Minimize sway and driver fatigue by improving the stability and driveability of your vehicle. The bar on this sturdy, effective anti-sway system mounts to the rear axle and to the frame to balance weight transfer and reduce body roll.

Specs:
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.
Superior Construction
The Roadmaster anti-sway bar is made of black powder-coated 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.

Everything pretty much fit like it should. Seemed to reduce the heavy rocking when You make sudden turns or coming out of a parking lot where the road is at a different level.
What a serious improvement on my motorhome made it so stable. It’s actually unbelievable how nice it drives now easy to install fit perfect. Just amazes me every time I drive it how nice it is to drive. I don’t feel like I’m gonna roll over anymore.
Wow, This sway bar is big, heavy, beefy and strong. I saw all the great reviews but was still surprised when I got it. Installation was straight forward but I did have to have a mechanic shop jack the RV up and take the huge bolts of the U-bolts because my impact wrench was not strong enough. I've only put a few mines on it since I installed it but I have already noticed a difference.
It works great. I can definitely tell a difference.
I love both of the Roadmaster anti-sway bars I had installed right before a trip to Iowa. I purchased bushing kits for front and rear but, I didn't know the front sway bar came with new bushings. So I have an extra front sway bar bushing kit. The biggest difference I noticed right away was the handling on the highway. The people I talked to at etrailer were very helpful and always are when I call. Thanks
Have not opened. Looks good in the pict ure.
Roadmaster Rear Anti-sway Bar and Roadmaster Reflex Steering stabilizer made a 1000% difference on my driving experience. No more being pushed around by the big rigs or the wind. I recommend these upgrades to any motor home.

purchased a 1995 Fleetwood storm 30ft in 2018 install new tires and a alignment
went on a trip to AK from Mi it was exhausting trying to keep it straight and from swaying when trucks pass us . in 2019 I purchase a RM1139-143 sway bar from E Trailer Installed it and went on our trip back to Ak . This time no swaying when semi passes drove straight not exhausted at the end of the day Very , Very pleased with the difference it made
I Install it my self not real difficult if you have some basic mech. skills
Installed on a Tiffin Allegro 31SA by Whited Truck and RV Center in Auburn, Maine. The Roadmaster anti-sway bar and associated parts are rugged and of high quality. Installation time was about 3 hours; drilling the frame to secure brackets took the longest time. This anti-sway bar improved handing and reduced sway, especially on rough secondary roads.
Excellent product. Well made. Great instructions. Easy install with proper tools.
Made an incredible improvement in the handling of our 35 ft MOTORCOACH with F53 chassis.
All necessary hardware was included. Delivery and shipping by etrailer was spot on.
Would definitely recommend to anyone wanting to greatly decrease sway in a coach.
I just received the product, which weighs in at "Over 70 pounds" according to the UPS tape attached, and will be returning it unopened once I receive the Return Authorization slip. Please note that this action had to be taken because of "Operator Headspace"on MY PART !!! I failed to properly read the requirements and limitations in their advertisement. The 1139-143 is for a motorhome with the Ford F-53 for an up to a max of 34 foot motorhomes. Mine is a 37 foot and need the one for 18,000 to 24,000 lb. My mistake and the correct one is on the way thanks to the help from the wonderful service personnel at etrailer.com. Great service for less than smart people like me... Thank you so much etrailer.com!!!
Sway bars and steering dampener are installed and the sway has been reduced and dies out much quicker. I am 80 and was able to install everything myself but it is hard work.
Very pleased with the improvement in ride and handling after about a year of use. Would certainly buy again!
took a lot of the rock and roll out of the coach
Sway bar made a big difference driving in windy conditions. The motorhome is much more stable than before.
Just got it today but all look good
ALTHOUGH I HAVE NOT INSTALLED IT YET, I AM SURE IT WILL BE
OK, THE WEBSITE WAS WELL WRITTEN AND EASY TO UNDER
STAND, AND THE ANTI SWAY BAR WAS DELIVERED TWO DAYS BEFORE PROMISED. GOOD JOB

Driving in the wind is a breeze. No more rock and roll. Great product. Very Happy
Great delivery. Checked all parts, ready for installation.
All the products I have ordered arrived promptly and in secure packaging. The pricing was great and with the free shipping I doubt you will find it for less anywhere on the net. I definitely will do business with the guys again. I will be sending photos of completed project when I am finished installing.
Thanks
Steve.
