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 motor home's frame and its rear axle, using the axle as a brace to more effectively balance the shifting weight of your motor home 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 cadmium-plated 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 had side-to-side sway in my 35 foot Class A motorhome on a Workhorse W-22 chassis. I initially thought shocks would help but after reading the benefits of rear sway bars on e-Trailer, I bought them. Wow, what a difference in handling and sway. As it turns out, this is what I needed and could have wasted $800 on shocks had I not read e-trailer's article and then confirming with my RV shop. Thanks e-trailer for a great recommendation, a great price and fast delivery. My upcoming 3,400-mile trip is going to be much more relaxing. 157033

I put the sway bar on a 2012 25t I did shorten the exhaust about 9 inches I think 2 or 3 inches would have been good. That was easy to do, as new as they are just take exhaust loose at first coupling pass the elbow slide it out and take some off the piece that goes to the inside. Worked well for me. Going from our drive onto the blacktop road in front of our place was all it tuck to decide it was worth the effort. It fit very well. Thanks Mack. PS I am 75 and 240 Made a man door step for drivers door .It works well Love it. Mack

Review from a similar Roadmaster Sway Bar with Bushing Kit in Anti-Sway Bars


I ordered both the Front and Rear anti-sway bar upgrade kits. The install on my 2016 E450 was quite simple, and accomplished easily in my driveway. The kit for the front was a simple remove and replace the OEM bar. The rear kit required drilling two holes to accomodate new mounting points. Other than that, it was also simply a matter of removing a few bolts, and replacing the factory bar. Some minor nits associated with the kits. The washers included in the kit for the rear didn't fit the bolts, also included in the kit. And, the instructions for the front kit didn't include torque specs for the bolts. A quick trip to the local hardware store, and a call to Roadmaster tech support solved the respective problems. Oddly, the Roadmaster tech guy read me THEIR instruction over the phone, and they DID include the necessary specs. I've intalled these kits on two different motor homes now. They work GREAT, and I highly recommend them if you're towing and it feels like the vehicle has a bit more roll than you like. HOWEVER, I would note that the difficulty of installation can vary widely. If you're planning to install yourself, I highly recommend downloading the instructions in advance, and crawling under your vehicle to check on accessibility. For the E450 kit, you'll have to be able to get under there with a drill, and not drill through any cables/lines that may run along the frame rails. You'll also have to be able to get a (typically somewhat large) torque wrench up in there. My experience suggests this can be nearly impossible on some vehicles without access to a grease pit or lift. Good luck! 302774

Review from a similar Roadmaster Sway Bar with Bushing Kit in Anti-Sway Bars


I received my front anti sway bar (RM-1139-140) around noon on the day it was promised. The package was undamaged and all parts were contained within. After lunch I installed the bar in less than 30 minutes, which included the removal of the factory bar. I installed it by myself from the ground. Simple install although I did deviate some from the instructions to make it easier for me as the bar is heavy. Instructions say to attach the bar to the axle with the bushings and saddle clamps first, then bolt the endlinks. Instead I bolted the endlinks first then simply swung/rotated the bar to the axle and attached with the saddle clamps. I did not have to lift the heavy bar to the axle as the weight was already supported by the endlinks. Easier if doing the install alone in my opinion. About a week prior I had installed a Roadmaster Reflex Steering Stabilizer ( RSSA-RBK9). These 2 items greatly improved the steering and sway problems which were extremely bad in my 2013 Winnebago Vista 26HE. So bad that I considered the drive extremely stressful and dangerous. With these 2 parts added the drive is now 80 to 90 per cent improved. Very happy. 263320

Review from a similar Roadmaster Sway Bar with Bushing Kit in Anti-Sway Bars


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


Comments

After over a year the sway bar is still the best investmentupgrade I made to the F53 to eliminate the tailwag of a motorhome with a long overhang. Handles great in side winds and on winding roads. The sway bar is well worth the cost and etrailer has the best price with free shipping.

Review from a similar Roadmaster Sway Bar with Bushing Kit in Anti-Sway Bars


Very high quality product. The bar is much more substantial than the original bar. I debated buying the Roadmaster bar for a long time because it is expensive but I never liked the way the original bar was designed to run through grommets in holes in each axle half. The Roadmaster bar provided an immediate ride improvement. 1 mile down the road on my test drive, I was already convinced I made a worthwhile purchase. I found a greater sway improvement by replacing the rear sway bar than the front but I do notice a definite improvement with the front. If I had to do it over again I would repeat my process which was rear bar first then front bar if I felt more was needed. 108360

Review from a similar Roadmaster Sway Bar with Bushing Kit in Anti-Sway Bars


I have completed the circuit of upgrading my F-53 RV chassis with Roadmaster anti-sway bars and steering stabilizer, and I am completely satisfied. I cannot the RV manufacturers put a RV on the market without these or competing product as standard or optional equipment. The front sway bar and steering stabilizer were self installed. Additional help was needed for the rear sway bar due to the 200+ pound torque and frame drilling requirements. ps> The instructions for the front sway bar indicated using the original hardware, but I used the new hardware provided. 230805


Comments

After a year, I am completely satisfied with anti-sway bar and steering stabilizer, without these additions, I would have traded the RV.

Review from a similar Roadmaster 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


Comments

After a year of use over about 8,000 miles, I have to say the improvement they made are moderate at best even considering I put them on the front and back.

Review from a similar Roadmaster Sway Bar with Bushing Kit in Anti-Sway Bars


I 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

Review from a similar Roadmaster Sway Bar with Bushing Kit in Anti-Sway Bars


Shipping was excellent! Product quality was excellent! I installed on a Pleasureway Class B Ford E350 chassis, it fit "like a glove". The chassis had 3/8" holes (short slots) in exactly the position required to bolt on the upper linkage end (after drilling out to 1/2"). The bar center positioned itself perfectly after bolt-up to the area in between the differential cover and the fresh water tank. One feature was the the center portion of the bar angles up from the two linkage ends, the fulcrum being at the axle U-bolt attach regions. Installing this angle up allows the antisway bar center "U" to tuck up and not interfere with access to the differential or reduce ground clearance. This was not addressed in the installation notes and was determined by trial and error. There definitely should be a specific note about installing on the E350 chassis for Pleasure-way RV addressing this. One other comment is that the bar is 1.5" and the vertical linkage bars are maybe 5/8" thick, could they buckle/deform when a strong force is transmitted via the axle given the stiffness of the sway bar? 22610

Review from a similar Roadmaster Sway Bar with Bushing Kit in Anti-Sway Bars


The product arrived quickly and complete from etrailer. I had these installed on my 2011 Sprinter 2500 144" about a year ago by a regional tire store. Seems like they charged me an hours labor, maybe a bit more. At first they were a bit tentative about installing someone else's product, but once they saw it, they said no problem. I remember them saying it was really straightforward with no unexpected challenges. Huge improvement. I didn't think it would make that much of a difference, but I noticed it immediately driving out of the mechanic's parking onto the street. The old rocking after crossing uneven ground is gone, but it's not too abrupt, either. I think it makes highway driving better as well but maybe that's my imagination. I've put on almost 20k miles since, and no complaints. Considering the many modifications and upgrades I've done since buying this Sprinter new, this is probably the best bang for my buck so far. Should have done it earlier, but I appreciate it more now, I suppose... 243777

Ordered on Monday and received on Friday. Installed on Saturday. No problem other than I had to trim the urethane bushings with a razor blade so hanger bar would fit over the sway bar end. Etrailer did an excellent job. 94397


Comments

Bar made major improvement. Reduced understeer. Sold van and bought Ford Transit. Do not think Ford will require any suspension changes. It is already a much better handling van than the Sprinter.

Review from a similar Roadmaster Sway Bar with Bushing Kit in Anti-Sway Bars


I purchased this kit and the Roadmaster rear anti-sway bar kit for installation on my 2015 Fleetwood Flair, 26-foot. Before purchasing, I called Roadmaster to make sure this kit could be installed on my small RV, as they make smaller kits for smaller RVs. They indicated it could be installed, and I'm glad I went with the heavier kit. The install took maybe an hour, with the only glitch being some difficulty getting the poly bushings and brackets over the new bar. I called Roadmaster, and the tech noted that the brackets DID look to small, but with some jiggling and finesse, the bolts should fit, and they did. My only irritation with this, and the rear anti-sway bar kit, is that the Roadmaster instructions do not provide ANY torque specifications for bolts to be replaced, either Ford F53, or kit specific, so be prepared to make some calls or go on an Internet search to find the right torque specs. 224319

Excellent product, I installed front sway bar and rear sway bar bushings in less than two hours without using air tools. Working by myself, I put end bushings and saddles on first, put sway bar in both sides then lifted bar and put in the two center bushings. Fit perfect, thank you Roadmaster for a quality product. Wow did it make a difference, really reduced side to side sway and much more comfortable driving. This was installed on a 2000 Winnebago Brave P32 Workhorse chassis. 248584

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

Box was torn up on receipt. One washer missing was all. Product was straight forward and is really ment for experienced installers as modifications to the product had to be made to install the brackets to the frame. We had no way to remove the rear wheels to drill the holes in the frame and had to work in the wheel wells. I like the over all product, it seems to me that they can and should make parts that will fit any frame application. 189934

This is the best possible upgrade to a Ford 53 chassis. It is like driving a different vehicle and virtually eliminated the side to side sway. The steering stabilizer eliminates fighting with the steering wheel and make it much easier to stay in the center of the lane. It I could do only one upgrade, these stabilizers would be it.

I have a F350 dually with a 2300 pound slide in camper that rocked to the point it was scary to go around a turn. I just installed the rear sway bar and the difference is unbelievable. I have just ordered one for the front. Well worth the money. 135527

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

It's not the same as a good pair of shocks. My 2008 durango still sways when going over uneven roads. However it does help it in a small way. 39795

Easy to install, but of questionable value. Reduction in sway was perceptible, but in the end it resulted in only modest improvement. 248522

  • Rear Anti-Sway Bar for a 2007 Winnebago Built on a Workhorse W24 Chassis
  • Roadmaster rear anti-sway bar # RM-1259-109 will fit your 2007 Workhorse W24 chassis. It is intended for models that are 33 feet or longer. Since yours is 36 feet long it fits that description. If you also want to upgrade the front of the RV you can use # RM-1259-105. Some other helpful items that will greatly improve ride quality and drivability include a steering stabilizer such as # RM-RBK13-RSSA, front axle stabilizer # TT2304 and rear axle stabilizer # RM-TRACW-22 (the rear one...

  • Improving the Ride Quality of an RV Built on a 2005 Workhorse W22 Chassis
  • Yes! Probably the single best addition you can make to provide better handling in your RV would be to install a rear anti-sway bar. Helper springs treat the symptom but not the cause like an anti-sway bar would. There are 2 rear sway bar options for your 2005 Workhorse W22: # RM-1259-108 and # RM-1259-109 (for applications 33 feet or longer). Additional products for even more stability include axle stabilizers: # RM-TRACW-22 or # TT2304 for the front and # TT2601 for the rear. And...

  • Recommendation for Roadmaster Front and Rear Sway Bars for a 2005 Fleetwood Bounder 34F
  • Yes I can! For a front sway bar to fit your 2005 Fleetwood Bounder 34F built on a Workhorse W22 chassis you would want the Roadmaster Front Sway Bar part # RM-1259-105 and for a rear sway bar you would want the part # RM-1259-108. I confirmed these fits with Roadmaster so they will work very well for your vehicle.

  • Parts Recommended that Will Reduce Sway and Driver Fatigue in a 2010 Fleetwood Fiesta Motor Home
  • One way to fix sway problems on a motor home is to brace the rear axle, to eliminate excessive axle side movement. The Blue Ox TigerTrak, # TT2601, and similar products, mount between the rear axle and the chassis and hold the axle in place. This will greatly reduce rear end sway. The TT2601 is the correct part for the Workhorse W22 chassis. This part is very similar to the Davis TruTrac bars made by Roadmaster and you will see similar results. Adding front and rear sway bars are an...

  • Roadmaster Rear Anti-Sway Bar for 2005 Newmar Kountry Star 3302
  • According to my research, your Newmar Kountry Star uses a Workhorse W-22 chassis, which would use the # RM-1259-108 Rear Anti-Sway Bar. Unless your motorhome uses a Firestone Ride-Rite air suspension kit, everything needed to install the Roadmaster anti-sway bar is included. If your motorhome does use the Firestone Ride Rite air suspension, an additional bracket kit, part # RM-590054-00 will need to be welded to the bottom of the air bag bracket. The RM-1139-143 is designed for motorhomes...

  • Rear Sway Bar Recommendation for a Workhorse W22 Workhorse Winnebago Adventurer
  • Actually for your W22 chassis RV the correct rear sway bar would be the # RM-1259-109 for if you are 33 feet or longer or part # RM-1259-108 for if you are shorter than that. There will be some drilling required for installation. I attached instructions for both products for you to check out as well.

  • Rear Anti-Sway Bar for a 2003 Winnebago Adventurer on a Workhorse Chassis
  • Regardless of the length of your RV you can use the Roadmaster anti-sway bar # RM-1259-108 (for 2003 Workhorse W20, W22, and W24 chassis). Bar # RM-1259-109 only fits the W22 and W24 chassis that are 33 feet long or longer like you said. Your 2003 Winnebago Adventurer 33V is 33 feet and 6 inches long so you can use this bar. I have also included a link to our help article on heavy duty vehicle stability for you.
