Features to know about

Steadier Steering in Crosswinds: Reflex Spring Keeps You on Course

When crosswinds or rough pavement try to yank your steering off track, this stabilizer keeps things under control. Its tempered steel spring constantly works to return your steering to center, pushing or pulling back into a neutral position whenever it’s compressed or extended. That means fewer corrections and a more predictable, straight path even when the conditions get sketchy.

Controlled Handling in Sudden Jolts: Centering Action Reduces Oversteer

If you hit a rut, edge of the road, or even lose a tire, this setup helps you keep your line instead of fighting the wheel. The tight connection between the tie rod and chassis keeps steering firm and responsive, and the spring’s centering force stops oversteering before it starts. It’s a huge boost in confidence when something unexpected happens out on the road.

Less Fatigue on Long Drives: Stabilizer Reduces Steering Effort

Long stretches behind the wheel can wear you out fast if you’re constantly making small corrections. This stabilizer keeps your steering centered so you don’t have to work as hard to hold your lane. The result is smoother tracking, steadier control, and less strain on your hands and shoulders mile after mile.

Quick, Straightforward Install: All Mounting Hardware Included

You don’t need to drill or weld anything to get the benefits of more stable steering. The unit mounts directly between the steering mechanism and chassis with the included custom brackets, hardware, and instructions. It’s a one-hour job that pays off every time you hit the road with tighter control and less wandering.

Video Transcript for Manufacturer Breakdown - Roadmaster Anti- Sway Options

Hello neighbors, it's Brad here from Etrailer and today, I'm with Jeff from Roadmaster. And today, we're taking a look at what you can do to your coach to enhance the suspension. So a lot of coaches out there, real top heavy feeling and people think, "Well, it is what it is. It's a big bus, you know, how do I improve this" But that's not necessarily the case. Roadmaster has a few different options to help make a better ride, overall. Definitely, it definitely does.

So typically, we educate our customer to let 'em know that yes, you can improve your ride or you can get that GT version suspension with your motor home. And how we do is we basically have to find out what's the root of the problem, okay. So typically, when a customer comes up to us, the very first thing they say is, "Hey, I'm constantly doing this when I'm going down the road." That that just means so many different things. So we actually ask a few more questions. "Hey, do you tow a vehicle behind your motor home Does it get worse when you put that motor home behind, or that vehicle behind the motor home And when it does, is this getting worse as well" And when the answer is yes, yes and yes, then we kind of know that the issue is tail wag at that point.

And that's usually fixed by a product called a track bar. And what it does, it just locks the rear axle in place. So it's not moving side-to-side. It's only moving straight up and down like it should, okay Or the next thing that I typically ask my customers is, is "Whenever you go in and out of turns, does it feel like the coach wants to roll over to its side" Most of the time, the answer is yes. And typically, the reason why is because when that coach or when the chassis was manufactured, they really had no Earthly idea what the final output was gonna be, how tall it was, how much weight was gonna be on it.

So you actually took center of gravity from probably a foot and a half, to a foot off the ground and all of a sudden, you're six feet off the ground or eight feet off the ground. We're putting air conditioners, solar panels, satellite dishes, everything else on top of these things. And we just need to drastically improve that. So how we do that in this case, is we upgrade the sway bars. In some cases, we're doing a remove and replace.

In other cases, we're actually piggybacking, adding a second sway bar to the rear or to the front of the coach. So sway bars are something predominantly, you see on passenger vehicles. And when I started working here, putting a sway bar on an RV, I go, "Well, I mean it's the same concept, why not" But seeing the difference, I've done sway bars on my own personal vehicle and the first turn you take, you go, "Oh, that's a lot better." Definitely. It's no different on an RV, in fact, it might even be. Jeff Much more noticeable. Yeah, absolutely, 'cause. Or before driving, it does feel like it's gonna topple over and you don't necessarily get sports car handling, but it's more response on the steering, it's more direct and you just feel a little bit more planted, more, honestly, confidence when driving. Yeah, and a lot of our customers are reporting back up, you know, they're saying up to a 60% increase in how they feel that their coaches is handling. And that's what we really like to hear and that's where we're trying to aim for. We wanna give that customer their vacation the minute they start out of the driveway and not once they get to their destination. Yeah, and so as far as sway bars, there's rear sway bars as well as front sway bars, correct Correct. So why would someone choose one or the other or should they go with both Typically, we suggest both. In some cases, yes, you can start off with the rear, but like I said, again, we like to suggest both because we're actually tuning the bars for the weight of that vehicle that it's gonna carry. So to have an upgraded bar in the rear and not one on the front, kind of does it a little bit of injustice. That's fair. Now something else too, as a long drive that's gonna wear you out is, is fighting the steering wheel back and forth and you guys have a way to fix that, correct Absolutely, we sure do. So once we turn and look at all the issues that the customer has, we determine what the issues are, we start talking to the customer and we resolve 'em by doing track bars, sway bars, the last and final thing that we usually recommend is a steering control. So basically, what the steering control does and essentially, is put center force pressure on a tie rod. So that way we're trying to hold that vehicle in a straight line. So if the customer has road ruts, if they turn around and hit potholes in the road, high winds, it's an assistance for that customer to keep in a straight line on their coach. Yeah, and that's, again, one of the installs, many of the installs that I've done is the steering stabilizer. And again, that's one of those, "Does it really make that big of a difference" Well, just going through our parking lot and cutting it, you let go of the steering wheel and it kind of still just tracks that way, whereas the steering stabilizer, you can see the steering wheel go back to center and then, when you're just going down a straight line, it just feels like it's in a nice natural groove. Jeff Yeah, sure does. So it's definitely a lot more comfortable, especially, you know, putting a lot of hours on the road or doing any twisty-turvy, you know, curvy roads out there, it's just gonna help balance it and kind of counter steer a little bit for you, bringing it back to center. That way, you're not having to fight that wheel back and forth. Now with both of, you know, our front sway bar, rear sway bar as well as the steering stabilizer, that's gonna get you a really good ride. And I think overall, better drivability, these also still work in conjunction with other suspension enhancements that you can add on as well, so you can really deck out the suspension of your RV. And I think it's. You'll be a believer once you start doing these, you're just gonna enjoy driving it more, I believe. Exactly, it brings the vacation back and the fun back into RV-ing. Yep, absolutely. Well, this was a look at some of the Roadmaster suspension components to just get your coach going down the road a little bit safer and a little bit more comfortable. Thank you Jeff from Roadmaster, for taking the time to break that down for us. All right, thank you.

Definitely a game changer my wide body motorhome drives straight down the road without white knuckling it



by:

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.



by:

I installed the stabilizer on a 2009 Pleasure Way Excel RV built on the E350 super duty chassis. Original handling of the RV was extremely poor with significant sway, oversteer and wandering that made it practically undriveable at highway speeds. Passing semis, road crown and rutting caused major problems with stability and created a true white knuckle experience.

Prior to installing the stabilizer I had installed a Roadmaster rear sway bar and Helwig front sway bar. Each was a noticeable incremental improvement, but the van was still prone to wondering with constant steering adjustments needed to stay on the road. This made for a very tiring experience. The steering stabilizer made a huge improvement. Can drive at highway speeds even with brisk cross winds and still feel stable. I had high hopes for the stabilizer but it honestly exceeded my expectations. Would highly recommend the kit for folks with a similar van with similar driveability issues.

I installed the stabilizer myself on a gravel driveway and completed the install in about and hour and a half. Please note that the frame on the 2008 E350 used for my 2009 RV WERE NOT tapped. I had to tap these myself to accept the M10x1.5 mounting bolts. Check your frame before starting the project and if you are not comfortable with this type of work then please consider having a shop install for you.

I would highly recommend this product.



by:

installed steering stabilizer along with a set of timbren blocks, what an amazing difference. easy directions andinstallation. delivered 1 day earlier than date posted. thank you!



by:

I was able to assemble the Reflex Steering Stabilizer by driving up onto 2 X 12 boards, and using my creeper, and an impact gun
. It took about an hour to assemble.



by:

Steering feels slightlymore solid than without it but thought it would bring the steering back to center which it does not. Also did expect it to have more impact when being passed by large trucks. Not sure if I would recommend it.



by:

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.



by:

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.



by:

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.



by:

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.



by:

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.



by:

I did the drive to find center on steering wheel which made installation easier. Removing existing steering stabilizer and brackets and installing the new wasn’t difficult at all with just basic tools. Read instructions and watch video at etrailer site. The reflex steering stabilizer is worth the money but should be the last modification done in my opinion. The first thing to install to help the swaying, leaning or just being pushed around by the semi trucks is #1 Roadmaster rear anti-sway bar if the manufacturer left the original small one on. #2 Roadmaster front anti-sway bar. Then #3 Roadmaster Reflex steering stabilizer. I say Roadmaster because the bushings and linkage for all of these are very heavy duty compared to the others that I compared. After doing all three of these upgrades to my 2022 E-450 33 foot class C the driving has gone from seriously gripping the steering wheel to driving relaxed with one hand in high wind or the passing of big rigs and ruff dipping road surfaces. I did this upgrades one at a time in the order I’ve indicated so I actually got to feel how each item help to control my motorhome. I am very pleased with all. Thanks etrailer for the excellent service.



by:

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!

Makes driving my motorhome a pleasure.Its an absolute night and day difference.



by:

This stabilizer is great! Installed today (10/24) on my Georgetown 34H5. Took my it for a ride down Interstate 20 for about 5 miles. Was passed by a couple of semis and hardly felt anything! Your product is great. Looking forward to my trip to New Orleans in January.



by:

It does do a good job. The only possible change that I would like to see is to the attachment at the tie rod end. It can be a challenge to torque the u bolts to spec.
Thanks



by:

Improved the handling but was just barely able to fit it on my Chevy Express 4500 chassis with a little modification to the bracket.



by:

If you have a Ford E350 or E450, but this. Your future RVing self will thank you. East to install and a real game changer when it comes to driving. It takes attention to detail to get it centered but it is not difficult to get it done. No more wandering from lane to lane and no white knuckles when driving in the wind or meeting wind jamming semi truck.



by:

The Roadmaster Reflex RV Steering Stabilizer has made a huge improvement in how our 22 E 450 coach drives. We live in South Central Kansas and wind is often a big problem . The Relex has been a great investment .



by:

Our Ford E350 got blown all over the Interstate on trips. It was so dangerous at times. At first I installed Bilstein shocks and though they helped a little, installing the front and rear anti-sway bars and the steering stabilizer made all the difference in the world. I changed them all at the same time so I don't know which one helped the most. These are certainly quality products and are pretty easy to install.



by:

Relatively easy install - huge difference in the steering of my Coach.

Steering is tight , no wandering ,love the return to center !!

These should be standard equipment on every motorhome sold - no exceptions.



by:

It took me about an hour to install the RM stabilizer and was surprised that no adjustment was needed after the test drive. I had to call back e Trailer to get torgue specs since it was not included in the package. Overall a great investment my van drives a lot better particularly on the freeway.



by:

As of right now it gives a tighter feel to the steering. I had it put on by a local Rv dealer on 1/2026 for the up coming camping season. I have a Coachmen 29FW 2024



by:

Quality built steering stabilzer. Well packaged and arrived within my expected time frame.



by:

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.

  • Is There A Steering Stabilizer for my 2020 Tiffin Phaeton with the Power Glide Chassis
    That's a really good question, Patrick. I checked with Safe-T-Plus and was able to confirm that part # ST59YR will work with your chassis, as long as you have the IFS, independent front suspension. From what I could find out about your model, there are some with and without IFS, so you will want to check to make sure before getting the kit. If you don't have IFS, you will want to pick up the Roadmaster part # RM29MR. Their kit is made for solid axle models only. Have you done any other...
