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 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.

I have no more sway on our 2005 Fleetwood Southwind Class A after installing this sway bar. However, I must be honest, When I went to install this sway bar, I found that both of the bushings and one of the brackets that attached the factory sway bar to the chassis were completely missing. I replaced the bushings and bracket at the same time that I installed this Roadmaster HD sway bar. I can't honestly tell whish fix or the combination made the difference. 728746
I purchased a 2000 Itasca 35U on the Ford Chassis last fall. On the 250 mile drive home on the Coquihalla Hwy in BC Canada ( highway thru hell ) I was white knuckled and afraid this was not ever going to be enjoyable or safe drive. Did I waste my money? No. With a little research I found what I hoped would save my dream of hitting the road in this motor home. I found etrailer on line and they had everything I wanted and at the best price I could find anywhere. I purchased the Roadmaster Front and Rear Anti-Sway bars for this Ford chassis and replaced all four shocks. The " Roadmaster Products" transformed the drive better than I could expect or ask for. It feels safe and solid on the road! I am so thankfull. etrailer earned my business and trust. If you are looking to feel safer and more in control in your motorhome, buy this package! I deserved to enjoy a safe and stress free ride and so do you. In conclusion, etrailer and their Roadmaster products are a must for this motorhome. 587694
Great service. Shipped UPS 3 days. Arrived yesterday. Some of the packaging could be better, but overall I'm very happy. Haven't installed yet, I'll post some pictures of them later. Hopefully they will improve the ride/driving in my F53 chassis motorhome as much as Roadmaster claims. 566799
Bought this a year ago. Arrived promptly. Installed with no real problems. I had to get a larger torque wrench to get the bolts tightened to specs. 5000 miles later, I have really enjoyed the improved handling. I also installed the front sway bar. I would highly recommend this to anyone. 390801
I received but not installed .I will get back with you with pics and review in a few months after I travel some. Order was received and shipping was spot on. great job! 363210
ROY J - 04/05/2018I installed the 1-3/4" sway bar kit. I have a 38' coach so wanted all the help I could get. Thus far the improvements to the handling have been very very welcomed. It's now a rarity that that I encounter any sway or push from passing trucks and barely noticeable sway from strong crosswinds. Now I don.t have to fight the coach constantly. Driving is much more relaxed. 360941
What a complete difference this made on my Class A motorhome. At highway speed, I am no longer pushed aside by the big rigs. The coach tracks straight a whole lot better, and body roll is improved. Installed it myself, with help from a buddy? Highly recommend this sway bar! This is my second purchase from etrailer. Both flawless, with quick shipping. 322342
It has significantly helped with sway of the coach. I am looking to install next year front steering control for additional safety. Etrailer is a great source to purchase RV products. 316485
Easy to install, but of questionable value. Reduction in sway was perceptible, but in the end it resulted in only modest improvement. 248522
Vince - 05/05/2017I bought this kit with the intention of installing myself, but a quick review of the instructions convinced me to take it in to a shop instead. The installation is not particularly difficult, but was facilitated by some tools that I simply didn't have. In particular, you'll need a BIG torque wrench to retorque the U-bolts, and on a lesser difficulty level, you'll need a very compact drill and stubby bit to install the frame brackets. I could not get a straight path to the correct location with my drill. It took the shop less than an hour, and was probably much simpler for them since they could put the vehicle on a lift. Otherwise, no surprises. The install could be completed by a home mechanic, but would require at least one somewhat specialized tool - a torque wrench rated to around 400 ft-lbs. The Roadmaster instructions suggest reusing the old U-bolts if they are long enough. I called a different source for new U-bolts, and the tech there suggested that, whether the old bolts fit or not, I should probably purchase new bolts. Apparently suspension U-bolts are threaded in such a manner that they are not intended to be reused. News to me. 224317
Good price , got it fast that = happy customer . The sway control was easy to install drilling the frame takes a good sharp drill bit . The only problem I had was when I install the bar I install it upside down witch make it hit . When I called RoadMaster after a bit they told me to flip the bar over . I told them in the instructions they only say to install bar , no this side up or this side down so I put it with the RoadMaster name up . He said there was a running joke if the label was down it probably was rite . NO JOKE TO ME . 204092
I ordered the sway bar on Thursday 8/15/2013 and received it on Thursday 8/22. That was very quick shipping for something as heavy as the kit. Price was the lowest I could find on the net. The list price is $980.00 found some places charge around $100.00 less then list plus shipping. Saved a lot by buying from etrailer.com. What surprised me was that etrailer.com was able to ship it right away, when I talked to Roadmaster they said the kit was out of stock and would be two to three week before it would be shipped, was told the samething by other's I checked with. Good experience shopping at etreailer.com, will be back. 96569

Installed on MB Sprinter 3500 RV. Corrected sway and yaw when being passed by big rigs. Install directions were confusing. Called Roadmaster, they sent better instructions and talked with installer and solved the issue. 643712
Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
RM-1209-131 delivered a day earlier than promised. Installed on 2018 Winnebago 24V View on 2016 Mercedes 3500 sprinter chassis. Good fit had to modify the exhaust which exits on shotgun side ahead of wheels which was to close to the long links. Drove 20 miles to my indoor storage. Quite a reduction to side to side sway. Handles like a different vehicle (better). Can’t WAITE till our next trip. Tulsa auto spring did the installation. Mikes custom muffler shop did the exhaust modification. Do believe l made the right decision not to tackle the job on my own $250 to install. $120 for exhaust modification. In Tulsa, Ok wouldn’t, go anywhere else to get the job done. 715992

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
Good anti-sway bar. Installation was made difficult by being unable to easily remove the OEM anti-sway bar. Although this item was intended to go on a near-new 2015 motorhome, the original retaining bolts were very difficult to remove. However, installation of the RM 1139-140 was relatively easy and completed in about an hour by one person. If two people did the task, it could be done in half that time. The only disappointment, and it was significant, is that there was no mention of torque values for the mounting bolts. 223089

Great customer service from purchase to delivery. Kept informed all the way by George with fast shipping. Sway bar was quick and easy to install on my 2018 Windsport, about 1 1/2 hours by myself. Considerably heavier than original, helps reduce sway as advertised. Great experience with company would purchase other items in future. 483047

Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
I received my order, but all the parts wasn't with it. All I got was the bar and the two bushing and brackets that mounts the bushing to the frame. All this came in one long box. According to the picture there are suppose to be more parts. I thought this is an expensive part for no more than I got with it. $ 600.00 for a bar really!! 211264
Review from a similar Sway Bar with Bushing Kit in Anti-Sway Bars
I put this on my 2015 Winnebago view. I left the stock swaybar and added this one to the front of the rear axle. It was the single biggest improvement that I did to the suspension. I can't believe Winnebago sells the RV without this upgrade. It improves handling in the wind or turning corners tremendously. 258934
