Best Class A Chassis Anti-Sway Bars

I found this easy to install however the bracket to hold it onto the steering rod kept slipping. NOT a good bracket design. In addition, the stabilizer only improved the "wondering" by about 30%.

Nick S was GREAT help. He helped me with the right stabilizer for my motor home and had it shipped the very same day. Stabilizer was installed with very little effort and it is making quite a difference in my ability to steer the motor home. I will definitely recommend etrailer to my friends.

The kit arrived in about 3 days and was complete. I installed this myself as I am pretty handy. Hardest part was getting to where the brackets attached to the frame for drilling. There was also a junction box of some sort that I had to loosen to access the holes to put in the bolts. Other than that, it was pretty straight forward as far as installation. If you're not mechanically inclined. I would suggest having it installed. It does make a huge improvement as far as tail wag and uneven pavement are concerned. I will be installing to front anti sway bars in the next month.

I submistted a review for both front and rear kits. Both etrailer and Roadmaster are great companies to purchase products. Roadmaster made custom parts and sent them within days.

Usual excellent service— sway bar delivered on schedule. I’m in the process of installing the front swaybar for my Bounder and I will update once install.

After a year of usage, I couldn't be happier with the Roadmaster front and rear anti-sway bar kits. The rear kit for my W22 chassy, the mounting hardward would not fit properly. I call Roadmaster directly and they custom built the mounts, painted, and shipped within days.

The good is that the parts are first class, and it works very well. Even being mechanically inclined, the directions could use an upgrade. Needs more help where the spaces go.

I installed these anti-sway bars front and rear because I was fighting crosswinds and passing semi-trucks, very exhausting driving. Made a huge difference. Our old Newmar (Workhorse) had no sway bars at all.

This installed in less than an hour, 2006 Monaco La Palma Roadmaster Chassis. I used a 1/2 cordless 1100 Ft lb. impact to remove the spring u-bolts, came right off. The rest is as the instructions say. I took for a road test and drives a straighter. etrailer shipped and I had in a couple of days. etrailer is the best for me. Tools for this is 1/2 drive 15/16 deep socket for the axle U Bolts, 3/8 drive 3/4 inch for the shock bolts and a 3/4 open end wrench, and a 3/8 drive 9/16 deep socket for the tie rod U Bolts. Easy to do yourself.

Thanks for the fast shipment of this order -- This stablizer was installed on a 07, Monaco Camelot, with a Dana Axle, & air bags -- Your web site states that the RBK6 will not fit a Dana axle -- I called Roadmaster, & they said it will fit, & it does --The The steering stablizer install was not a tough job at all -- The only problem was loosening the nuts that hold the axle, & the bolts not being long enough to add the bracket -- I do have air tools, & I heated the nuts with a plumbers tourch -- It took longer to free the the nuts, that it took to do the rest of the install -- On the test drive, no adjustment was needed -- Very pleased from order to install -- William Willard

Finished installing somo springs and rear antiswaybar couple of days ago. Products seem to be of excellent quality and installation was relatively easy. Have not been able to get out on the road due to Covid-19 but hopefully will be able to travel in a couple of weeks.

Installed roadmaster anti sway bar on 2005 Fleetwood Southwind. Easy install works great, drives much better. Already have a track bar and a roadmaster front sway bar. Thanks for the quick shipping

Haven’t driven RV yet, front axle track rod installed easy and feels heavy duty, can’t wait to take it for a ride. Highly recommend etrailer for parts and their service

If you have an gas motorhome this is one of the best investments you can make. I opted for front and rear trac bars along with new shocks . What a world of difference. Absolutely not pushed by wind or passing trucks. After traveling over the country’s really bad roads we had sumo springs installed. They help but the trac bars were by far a better improvement. We traveled 12,000 miles this summer plus 5,000 in a tow car. We crossed the great divide a half dozen times. All with confidence in a 2005 model fleetwood. I couldn’t imagine trying to drive that trip with the original equipment.

FIXING TO INSTALL. HOPE IT IS NOT TOO HARD.

Installation on my 07 W16 was not all that easy. I am 65 years old but have training and years of experience with mechanical systems. I would advise using a small hydraulic jack to hold the shock plate in place while replacing the u-bolts one at a time. The drivers side went quickly and very straight forward. A tungsten step bit makes enlarging the frame holes much easier than a twist bit. Every time I torqued the passenger side u-bolts they slid just enough to prevent the mounting plate from sliding on. I got it as close as I could and used a die-grinder with a large burr to clean out the somewhat crude holes in the mounting plate. On my motor home with 2 slide-outs and automatic leveling jacks, equipment was mounted to the inside of the frame right where the frame mounts had to go. On the passenger side I had to drill (drill press is best) new mounting holes in the supplied bracket to utilize one of the existing bolts and a lower hole for a supplied bolt. All of the bolts were a lot longer than necessary. All of the parts are over built if anything and disregarding the frame difficulties, I am quite confident the end result is very strong and should last a long time.

No issues. Significantly helps steering.

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.

The item arrived faster than expected, thanks for that, I’m waiting for the weather to clear up before I can install it myself, thanks again for the help and the support

The part that Amber told me was the correct for my RV does not fit The spring hits the frame and will not allow the shock to rotate up. I also would have to rotate the shock spring unscrewing it ! I will be contacting Roadmaster

The anti sway bar helped a lot, but my Fleetwood could use a little more help. Probably needs the front end too. I installed the model made for coaches a year or two newer and it went on much easier than the unit requiring frame drilling and coil spring recounting. I ordered both to cover myself, didn't open the kit for older chassis and sent it back - for full credit, except for shipping, which is fair. Trailer met each promise - product, dates, and return of the unused unit. 5 stars for service 3 stars for eliminating the sway. ETrailer provided EXCELLENT videos for installation, and did everything they said they would! My wife is happy and I'm her hero. That's always worth 5 stars!

I spoke with Jameson, he understood my issues and recommended 2 stabilizer bars. They were delived on a tight time-frame. These ba4s made all the difference in the handling of my Newmar Baystar Sport. THANK YOU FOR YOUR EXPERTISE!!

First, I did have to grind off corner of the plate that mounts under leaf spring bolts. It would not lay flush so I tapered one of the edges where it met the axel a little bit till it laid flush. I did buy a 3/4 inch wrench set but with an rv, it's good to have and will possible allow me to get the 22.5 inch wheels off in an emergency. This with a good solid 3' pipe and I was able to fairly easily break the leaf spring bolts free. I used boards to ensure the fronts tires were fairly straight, laying them alongside the tires and eyeballing to see where they lined up with the back tires which are about 4 inches wider than the front outside width. I mounted the steering stabilizer and took it for a test drive and it was good the first time, no additional adjustments needed. Feels good on the road, good around turns, and even at low speeds around the driveway, I did not notice any extra effort to turn the wheel due to the heavy spring on the stabalizer. Put about 75 miles on it and it feels solid and stable though no high winds or passing semi trucks yet. But my 2007 ford f53 22000 lb chassis under a holiday rambler admiral body has always felt pretty good. Just trying to make better, next up is the new koni evo fsd heavy duty shocks coming today.

I have a class A motorhome, F53. I installed a Roadmaster reflex steering stabilizer, a Roadmaster rear anti-sway bar 1 3/4" diameter, 4 new koni shocks and 6 new tires. Now, it feels well planted on the road. Its a combination. Very happy !

I own 1995 Spartan Mountain Master chassis. No anti swaybars from factory. Installed front and rear bars and am very pleased. Rv was difficult to keep in lane while being passed by large trucks or during high winds. Now much better. Installed my self. Rear bar required welding. Front less involved. Do recommend for this chassis.

First, Eric was a great help throughout the purchasing and installation. I watched the tutorial numerous times and set up my tools. I bought a 3/4 inch torque wrench at Harbor Freight and a 4 ft galvanized pipe at Home Depot. I followed the instructions and the tutorial to the letter. The bar and mounting plates are heavy, so be very careful. This job isn't for a beginner, but if you are somewhat mechanically inclined, you can install it. The 300 Ft. Lbs torque of the 8 nuts took everything out of me. LOL...I adjusted the end links twice, and it leveled out great. Now, I will do a test run and see how it improves the handling of my motorhome. Its a 2022 Entegra Vision 29S.

The Anti Sway Bar completely removed impact of Semi Trucks passing us on the highway. It also significantly reduces issues with wind. Even reduced sway related to rough roads.

Easy installation took me less than 40 minutes from start to finish. Test drive was a “remarkable” difference than before.

The hardest part is getting the U-boats off and back on again with 250 pounds of torque took me about an hour and I’m 73 years old so I think anybody could do it. We took it out for a test drive and it makes a big difference with the wheel coming back to center, even my wife found it easier to drive. There is know more drifting.

We put this on a 2002 Holiday Rambler pusher with about 70,000 miles. I looked at this system a few years ago but I wasn’t sure it would make much of a difference. Wow was I wrong ! We were leaving for an out west trip and so I thought it would be a good test. First off the coach never handled (bad) it just wasn’t great. I would say that this cleaned up about 80% of the steering wheel (sawing). I literally had to retrain myself not to constantly over steer the coach and let the system recenter me. I found myself giggling as I would start the day’s drive because it made that much difference. My only regret is that I waited 12 years before trying this steering stabilizer. It was simple to install (did it myself) and I didn’t even need to adjust it. I went for a test drive previous to installing and made note of where the steering wheel needed to be when going straight, then set the wheel in that position when I installed the stabilizer. Still amazed something so small could make such a difference.

Excellent to work with very helpful folks and quick responses Thank you
