Roadmaster Anti-Sway Bars

  • Steering Stabilizer
  • Roadmaster
  • Includes Mounting Hardware

The sturdy steel spring on this stabilizer keeps your vehicle in line by constantly working to maintain its position. Mount it between the steering mechanism and the chassis for a tight connection that will minimize wander and correct oversteering.


  • Compensates for oversteering and returns your vehicle to center
    • Tempered steel spring works to return to its normal state - when compressed, spring pushes back into neutral position; when extended, it pulls back
  • Attaches to the steering mechanism on one end and to the chassis undercarriage on the other
    • Tight connection between these components keeps steering firm and controlled
  • Helps you to maintain control of your vehicle in the event of crosswinds, rut tracking, road edging or a tire blowout
  • Reduces road fatigue - stabilizer keeps you centered so that you don't have to work as hard to steer
  • Installs in approximately 1 hour with no drilling or welding
  • Includes stabilizer, custom mounting brackets, hardware and installation instructions
  • Made in USA
  • Limited lifetime warranty

A variety of things can make your vehicle veer - crosswinds, uneven pavement, tire blowout. The key to a pleasant, and safe, driving experience is learning how to deal with these situations. Roadmaster's Reflex Steering Stabilizer works to return your vehicle to center when something happens that causes it to swerve or jolt. As a result, you won't have to oversteer in an attempt to stay in line, thus minimizing road fatigue.

The stabilizer attaches to your vehicle's tie rod on one end and to the frame on the other. A heavy-duty steel spring runs the length of the rod, constantly working to keep steering controlled. If you steer your vehicle one way and it gets pulled the opposite way, the spring will stretch momentarily and then quickly pull back to its normal state. If you oversteer your vehicle in the same direction it is already moving, the spring will compress for a moment but then push back out to its prior state. No matter how you steer or how the frame is pushed or pulled, your vehicle will always return to center.

Video Transcript for Roadmaster Reflex Steering Stabilizer Review

Speaker 1: Today we're going to be taking a looks at Roadmaster's reflex steering stabilizer with mounting brackets for class A motor homes. You'll want to verify in our fit guide which part number fits your inaudible 00:00:10.Now we're taking a drive without our steering stabilizer installed so we can compare the differences. Right now you can see there, when I hit bumps, you can see the wheel jerk. Once we get our stabilizer installed, that will help minimize those jerks in the steering wheel. What this means for you, is you're going to have more control over your vehicle, as well as it's going to reduce fatigue when driving down the road, because you're not going to have to fight to hold it straight like you we're before.As we head into our test course here, you're going to notice as we go over the various terrains, car's steering wheel's going to react. We're going to start with something that will simulate uneven pavement.

You can really see here how it jerks the wheel. Now you have to fight it to keep it straight. Next, we're going to be going over something that's going to simulate potholes or speed bumps. You can see how it still jerks the wheel, but not as bad as our uneven pavement did. Another think you'll notice is that when you're turning, on some of them back country roads, your steering wheel will return to center, but we'll see how much more our stabilizer's going to make a difference in bringing our vehicle straight for us.

As of right now, it continues to turn left and is not straightening out.Once we get our steering stabilizer installed, we'll show you the difference. You can already tell when we go over our bumps, our steering wheel doesn't move nearly as much as it used to. It's much easier to maintain control. We come around our turns, you see we let go of the wheel and it immediately bring our steering wheel back to center. Unlike before, where our wheel kept at an angle and our RV just went right around in a circle all by itself.

Here we can let go and watch it return.Now, as you can see when we're turning, you'll see our spring expand and contract. It pulls our steering back to center. You can see here as we go over bumps, the dampener bringing our steering back to center right away. What this really means for you, is it's going to help reduce driver fatigue by keeping the steering wheel straight, returning to center, doing a lot of the work for you. It's going to give you an overall more stable ride by keeping that wheel straight.

You're going to feel safer and more confident going down the road.This is what our steering stabilizer's going to look like when it's installed. It's going to mount between your tie rod and your front axle. It's going to help keep your vehicle in a straight line going down the road. This will help reduce driver fatigue, because you won't have to fight that back and forth motion while going down the road. It will also help stabilize your vehicle, making for a safer trip. This works using the large spring installed on the shock. As it expands and contracts, it's going to want to return to its normal position. Since we have it installed with our wheels in a straight line, it's going to try to bring those wheels back to a straight line. The shock inside of it is going to help absorb those impacts in the road, so if you hit any potholes or uneven terrain, that's actually going to help dampen it, making so you don't have so much of a jarring motion up on the steering wheel inside the vehicle.The spring is made of a tempered steel, so it's going to be durable and last a long time. It has a rust resistant coating on it as well to help extend the life. This will help improve the safety of your motor home, especially on those long trips, because of high crosswinds that you may encounter in certain areas, uneven rough terrain, and in the even of a blowout it will help you maintain control so you can safely pull over. It comes with all the hardware you need to get it installed. There's no drilling required and it's a really easy quick install.Our customer William J. Had to say, "Our Winny Brave experienced violent front end oscillation at three different times; after driving over diagonal rail road tracks on two occasions and once again after a pothole I had the front end aligned and it needed it. The shop recommended the steering damper to remedy the oscillation problem. I drove the unit 36 miles without the addition of the damper and handling was improved, but it still drifted and changed directions with road surface changes. I have put another 36 miles on the unit since the damper addition and I can feel the change. The steering feels rock steady with no side to side drift or direction change, even some over some of our local rough roads. We are planning a trip that will take us back over the diagonal railroad tracks and I can't wait to see if the violent oscillation is gone for good. Initial indications are that the problem is cure."William J.'s right. I could tell a major difference just driving around on our test course here and the few moments we had with it. Compared to other suspension enhancements out there, such as sway bars and air bags, none of those are really going to achieve the same level of stability that this is on your steering when going over bumps. Those are going to be great to help prevent sway and other things, but not for that direction of center that this is going to bring back.That complete our look at Roadmaster's reflex steering stabilizer with mounting brackets for class A motor homes.

The sturdy steel spring on this stabilizer keeps your vehicle in line by constantly working to maintain its position. Mount it between the steering mechanism and the chassis for a tight connection that will minimize wander and correct oversteering.


Excellent setup, road manners are so much better. I don't have to work to keep the truck straight anymore. Installed in less than an hour with just a few basic tools.

2004 Chevrolet Kodiak

This stabilizer made my truck much safer to drive. When pulling a trailer, the truck was difficult to handle. Any line or imperfection in the pavement would lead the truck around and cause it to sway. It now handles much better.


Had an issue where the top eye rattled loose and the spring parted company. I contacted Roadmaster and they had a brand new complete unit shipped to me no charge the next day.

I didn't think support like that existed anymore.


Product was great and installed with ease , ordering and arrival was on time and accurate , Angela was a great help and great at her job ! Thanks to her we are on time and ready to roll ! Thanks again Angela we will be doing business with you again soon ! Sincerely your customer Jeremy Gerstner

2005 Chevrolet Kodiak

Stabilizer showed up quick. Easy to install for someone who has some knowledge about the vehicle. You better have 3/4 in drive tools for the U-bolt nuts one truck. Requires a large amount of torque to remove and reinstall them. Only have one test drive on it, but much improvement already. Would recommend this to stop the road wander.


Review from a similar Reflex Stabilizer in Anti-Sway Bars

We have driven about 3,400 miles since the Roadmaster Reflex Steering Stabilizer install. I can honestly say it has made a significant difference in the handling of our Class C RV. Before installing the Stabilizer the RV steering felt like it wanted to drift one way or the other depending on road conditions. This is no longer the case. Much less work to steer.

I still feel this has helped a lot. High winds will be an issue with almost all motor homes. Under normal or 65 or less mph traffic I feel less hassle in steering.

Review from a similar Reflex Stabilizer in Anti-Sway Bars

We had this installed by Camping World on our 2019 Thor 26HE. It was a handful on the interstate when a semi passed.

Now there is just a small push-pull when they pass with the steering stabilizer.

I recommend this to everyone who buys a C Class RV.

Fantastic our Thor 26HE still handles like a dream on the interstates.

Review from a similar Reflex Stabilizer in Anti-Sway Bars

I installed this on my 2003 Chevy Express 3500 Roadtrek Class B motorhome to help with steering wander. It improved the issue by about 75%. A noticeable improvement. The instructions were a little difficult to follow, but with some tech support help, I was able to remedy the issue by reversing the position of the small end bracket (see pic) that attaches to the steering center link. This is basically a shock absorber (dampener with spring) mounted horizontally on the steering Linkage. It worked well.


Review from a similar Reflex Stabilizer in Anti-Sway Bars

Installation not terribly difficult. Driving considerably easier after adding this product. There is still room for improvement, so we will be looking at other solutions as well, but we are very pleased with this upgrade. I am particularly impressed with etrailers tech support and purchase experience. Highly recommended.

A year later, were still very happy with the product and even more pleased with etrailers buynig experience. They are now our first go-to for trailer or RV equipment and parts. Very knowledgeable and always ready to help. Thanks!

Review from a similar Reflex Stabilizer in Anti-Sway Bars

To start off, the folks at etrailer were the most professional and helpful. I cannot remember a company I have dealt with in the past that offers such help in determining the correct product and answering my many questions.

The installation of the RBK22 bracket was flawless. I was very concerned because of the size of my Newmar Country Star 3911 motor home (26,000 GVRW). The U bolt nuts came off without a lot of strain, since I went out an purchased a 3/4" breaker bar. We installed the mounting bracket and re torqued the U bolt nuts to the factory 250 ft. lbs of torque.

Installing the RSSA went smooth as well. Check out the pictures below. We then took the motor home out on the freeway and drove it between 65 - 70 mph. Steering was wonderful! Before, I could only drive 55 mph and had to constantly fight with the steering wheel to keep the motor home straight.

Thank you etrailer and Roadmaster for such a great product!

Ron W.

It’s been working great. Have take two cross country trips and zero sway from big truckers or high winds.

Review from a similar Reflex Stabilizer in Anti-Sway Bars

We've put 3500 miles on our rig, traveling through 5 states in 9 months, and I feel the Roadmaster Reflex Steering stabilizer was well worth the money. Our '98 Safari Serengeti didn't have a lot of wander before, but I could get some bump steer and rut tracking on worn or bumpy roads. I'm having to make fewer corrections in these conditions after installing the stabilizer. Also it's really helped while towing our Honda CRV. I get much less tail wagging the dog. Only had one small issue and that was the U-bolts on the tie rod bracket would slip over time allowing that end of the stabilizer to sag down out of alignment. There weren't enough threads to get it tight enough, but adding a couple washers solved the problem and it's been fine for 1000s of miles after that.

Installation was easy and didn't take any special tools. I just took care to make sure my wheels were straight before tightening it down. Took it for a test drive and there was no need to make any adjustments. You can use a simple string line from front to back tires across the outside of the tires to get the front tires straight.

While I hope it never happens, I feel better having a stabilizer should I have a front tire failure.

Another year and a total of 9000 miles of driving has passed and the Roadmaster Reflex Steering stabilizer continues to work very well. Weve recently driven through the plain states where gusty side winds tried to push me around. I cannot imagine what it would have been like without the stabilizer. Im still very happy with its performance. Semis passing me in narrow lanes are no longer a white knuckle experience. It wont fix all the wander of your RV but it certainly helps.

Review from a similar Reflex Stabilizer in Anti-Sway Bars

What a difference this made. I was on the fence about this for quite a while because of the investment needed. Now that’s it’s on my 2018 Coachman Freelander 28QB sitting on a Ford E450 my only advice is don’t wait any longer, put this on as soon as possible! It took all of that steering wheel shake out. No need to hang on with a death grip anymore. The stabilizer is very easy to put on, it took me about 1 ½ hours to complete including taking the old one off. Just follow the great video and printed instructions from etrailer and you will have no problems at all.

Its been a year and many miles since I placed this upgrade on our motorhome. Im so happy that I did! If your thinking about this, based on my experience I say do it and dont look back. I believe you will love the difference in steering.

Review from a similar Reflex Stabilizer in Anti-Sway Bars

Works well, install was a little tough as the video showed mounting bracket instructions different then the bracket I installed . I had to remove the spring u bolt nuts. That was not an easy task. Had to use a breaker bar and my legs to remove them. Install was easy and took about 20 minutes. Steering feels good.Happy with etrailer and the product.

it has worked out well, no complaints
Rick R - 07/08/2020


Review from a similar Reflex Stabilizer in Anti-Sway Bars

My coach came with a great suspension upgrade from the factory for the rear, but the front, not so much. I did two upgrades for the front. One was a anti sway bar from Roadmaster, which was awesome, and the second was the Roadmaster Reflex steering stabilizer. The stabilizer was the icing on the cake and made a huge difference. Going down the road now feels safe and secure and for a 30ft rig, handles like a much smaller vehicle. Love it.


Review from a similar Reflex Stabilizer in Anti-Sway Bars

Installed the roadmaster stabilizer on my 2017 F450 Fleetwood Jamboree and just got back from the test drive. Got the positioning just right on the first try. This with my sumo springs have completely transformed my ride.

Excellent product. Driving has been greatly improved!
Steve M - 02/24/2020


Review from a similar Reflex Stabilizer in Anti-Sway Bars

Installation was easy and it made a significant improvement in controlling our Forest River Sunseeker especially while driving on the interstate. Prior to installation it was hard to control our rig when a tractor trailer or equal size vehicle passed us on the road and ever since we installed the steering stabilizer, driving has been less of a white knuckle moment.


Review from a similar Reflex Stabilizer 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.


Review from a similar Reflex Stabilizer in Anti-Sway Bars

I installed the Roadmaster Steering Stabilizer on my 2017 Thor Miramar 34.1. The installation was pretty simple and straight forward after the passenger side leaf spring u-bolt nut removal. Those leaf spring u-bolt nuts are torqued to 250 ft lbs and it required a 24" long 1/2" drive breaker bar and a 1-1/8" deep socket to get the job done. Torquing those back to 250 ft lbs while lying on your back underneath the coach is a challenge. I'm just saying all this for anyone considering home installation. The rest of the installation was a breeze and upon performing my test drive I was impressed with the improvement in the steering handling. I also installed the Roadmaster rear anti-sway bar and I am very impressed with the improvement in the ride and handling of my coach!


Review from a similar Reflex Stabilizer in Anti-Sway Bars

So far so good; after installation of the stabilizer the rv steering straight as expected. I have not going the highway yet but... locally; the rig is doing well... and doing very well sitting at the drive way looking pretty!... i have to revisit this review for the final test of 1000 miles.

etrailer's staff is very helpful in communication and responsive through email support. I rather pay little more for the product with the proper guidance and advice from etraile'r staff. I included a few pictures after i installed the stabilizer at night.

On the installation; the instructions doesn’t instruct you to put red lock tight on the nuts; but i put the lock tight on there anyway to reinsure the nut doesn’t come off due to vibration since the bolt and nut holding the bracket barely shows any treads after torque.


Review from a similar Reflex Stabilizer in Anti-Sway Bars

I ordered this steering stabilizer for our 2011 Winnebago Adventurer 32H. As always it was on my doorstep in just a few days.

Installation was pretty straightforward although I did have to call Roadmaster for clarification on the mounting location. I've included pictures that should be helpful for anyone else installing it. Particularly notice where the plate mounts on the leaf spring u-bolts.

The stabilizer works as described and I did notice a much better handling experience after installation. Glad I purchased it.


Review from a similar Reflex Stabilizer in Anti-Sway Bars

I bought this stabilizer for a 99 class A Motorhome. The steering stabilizer kit came quickly and complete. Instructions are easy to follow. The whole install took about 40 mins. Just a couple adjustments to center the steering up. I initially bought the stabilizer because in strong crosswinds the motorhome was hard to maintain lane control. The stabilizer has improved handling. You must also insure that other steering components are not worn. I recommend the Roadmaster Steering Stabilizer for older Motorhomes.


Review from a similar Reflex Stabilizer in Anti-Sway Bars

If you are on the fence about installing a steering stabilizer just do it and be rid of the dangerously exhaustive driving and start enjoying your Motorhome.
I am, by nature, a very skeptical person. However, the 2018 Thor Freedom Elite 26HE I own was a dangerous thing to drive. I already installed Air bags and a heavy duty rear sway bar; the Motorhome was no longer dangerous to drive but will work you to exhaustion fighting the wind and passing trucks. I researched and inquired about how to fix this and was told to install a steering stabilizer. After installing the Roadmaster Reflex Stabilizer I took my Motorhome for a drive expecting to be disappointed and more financially broke for chasing ghost; WOW was I wrong! I didn’t just notice a minor improvement but an improvement so major that I had to share this information with everyone I know and anyone I come in contact with that has the same problem.


Review from a similar Reflex Stabilizer in Anti-Sway Bars

Just had the Roadmaster Reflex Steering Stabilizer installed on my 2007 Coachman Freelander Class C motorhome (28 feet) with Ford E-450 chassis. On my first test drive what an immediate and noticeable difference! Met several semis and the improvement was evident. The motorhome is much easier to handle. I look forward to upcoming road trips. Service from etrailer was EXCELLENT!


Review from a similar Reflex Stabilizer in Anti-Sway Bars

What a difference in handling. Even my wife could notice how steady my 24' class C handles. Prior to installing I would grip the wheel hard with two hands, it was very tiring. Now I don't sway all over the place while being passed by a semi. I took a shot and glad I did. Simple install.

Thanks for you help Rebecca N

Big difference, now I wouldnt ride without one. Just bought a New RV and added it.
