Features to know about

Steady Control in Crosswinds: Nitrogen-Charged Gas Spring Keeps You Centered

Getting pushed around by wind or road ruts can make even a short drive feel like a workout. The Roadmaster Exact Center uses a nitrogen-charged tandem gas spring that applies full force right when you need it. Instead of reacting after the steering starts to wander, it works proactively to keep your rig centered and steady. That means less correction, smoother tracking, and a big drop in those white-knuckle moments when the road turns unpredictable.

Better Handling and Responsiveness: Prevents Wandering Before It Starts

Most stabilizers only step in once the steering drifts off center. The Exact Center is different—it’s always working to prevent unwanted motion before it happens. By tightening up that soft spot in the middle of the steering, this system helps your setup respond more immediately to input. The result is tighter, more confident handling that makes long drives and narrow lanes a lot less stressful.

Durable Construction: Heavy-Duty Stainless Steel Build

Every part of this setup is built to last. The stabilizer itself is heavy-duty stainless steel, tough enough to take on rough roads and years of use without losing performance. It’s a simple design that stays strong, reliable, and consistent through every mile.

Simple Installation: Custom Brackets, No Drilling Required

There’s no need to drill or weld to get this stabilizer in place. It mounts using the factory axle bracket holes and tie rod location, with custom brackets included to fit perfectly. With all the hardware ready to go, the install is straightforward and clean—you’ll be back on the road with a steadier wheel in no time.

Built for Confidence: Medium-Duty Performance up to 22,000 lbs GVWR

Designed for medium-duty applications, this Exact Center is rated for chassis up to 22,000 lbs GVWR. With a 32" spring length (from center of bushing to center of bushing), it delivers the right balance of strength and precision for your setup—keeping you in control and ready for whatever the next road brings.

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.

No more white-knuckled driving on your adventures. This gas spring steering stabilizer will help keep your rig from wandering while also giving you responsive steering. Includes custom mounting brackets.

by:

Hey RV'rs.... I upgraded from the Roadmaster stabilizer and the difference was phenomenal... Prince Edward county to Key West with minimal steering correcting



by:

This it the second Roadmaster stabilizer I have purchased from Etrailer. Other was for our older 2011 motorhome and after having it I did not want to drive without 1. This is different than prior unit- big factor is so much lighter and easy to adjust, so far working perfectly…



by:

I stopped short of 5 stars because the instructions could be a lot clearer.



by:

worked great and was easy to install



by:

This is absolutely a must for anyone with a Class A gas motorhome and fighting the steering. Steering feels tighter and self-centers quickly. Makes driving my 35' RV much easier and a LOT less fighting with steering when passing big rigs or in wind.



by:

The motorhome drives so much easier now. I would recommend this if your on the fence.



by:

I installed the exact center myself. It took me about an hour due to a couple rusty bolts. Test Robin on some side roads and the main road today and I love it. Keeps me on the lane. I don’t have to play the wheel back-and-forth constantly. It doesn’t pop back to center as quuck as I thought it would, but maybe I just gotta get used to it. Definitely an improvement for a long trip.



by:

This has improved the steering significantly for our 2021 Jayco Redhawk 25R! It's almost incredible how much better it is. Can now hold the steering with one hand and does not pull in one direction. Huge improvement!



by:

Supper easy install takes about 1 1/2 hours and most definitely made a difference in the steering input and holding the road is definitely improved.



by:

I will have to wait until next year to install the stabilizer. I had to have the kingpins replaced in the Ford front end at 13,500 miles because parts were left out at the factory. We were not able to use the motorhome much this year.



by:

Joshua did a great job on the phone with me.
The product that I bought seems to be high quality.



by:

Do not like how it handles with the center steer



by:

Made a world of difference. Installed on a Class C RV and was a marked improvement over the anemic OEM “steering stabilizer.” Very little adjustment required.



by:

Best investment I have made on this Motorhome. So much easier to drive and keep in it's lane.



by:

Super easy install on a 2019 Leprechaun 319MB ,Class C RV. Hardest part was taking off the old hardware. Followed the instructions and test drove at 60mph and it drove totally straight and did not have to make any micro adjustments. A very well made product.



by:

I had the road master exact center steering stabilizer installed on my RV and tried it out and it was perfect driving and maintaining position on the road way with out drifting. Although my tow vehicle was not connected I thought it felt good without out it a believe it will be fine.



by:

Everything arrived on time. I did a preliminary fit check, parts look beefy and it looks right for my vehical. Just need to find steering center and install it. So far so good !



by:

We installed the Roadmaster steering stabilizer on our 2018 Thor Chateau 24F motorhome. The drifting issue we'd experienced was significantly improved making driving easier and less stressful.



by:

Great product! My installer Martins Auto Tech did a fantastic job!!! Jeff Martin the owner took the extra time to make sure everything was aligned correctly and took the time to explain why he liked the product we chose from etrailer! If i ever needed or will need any work done to my RV. I would use etrailer and Jeff Martins Auto Tech in Hollywood Maryland! Btw your source page led us to Martins Auto Tech with great reviews! Thank you again!

This one of the best if not the best exact center steering stabilizer on the market. Steering my 38 foot class A gas motorhome is simply a breeze. I use to fight my steering wheel to keep my motorhome straight on every type of road. I use to brace and prepare to input multiple steering corrections whenever a Semi truck was about to pass me. With my exact center steering stabilizer installed plus the addition of air bags (front and rear) driving my motorhome is now as easy as driving my F-150 super duty. The exact center steering stabilizer alone improved all of the white knuckle constant steering adjustments i was experiencing. The air bags prevent the side to side movements from cross winds and when a Semi truck passes my motorhome. The vast improvement is the same with or without the toad. This was by far the most cost effective, easily installed, and immediate improvement I have made to my 2015 Coachmen Encounter 37LS Motorhome.



by:

Easy to install if you have the right tools, 3/4" torque wrench etc. Seems to be doing the job on smooth roads, our roads are terribly rutted and lots of frost heaves. Did not have to adjust after install.



by:

First road trip with our new Integra Odyssey from New York to Key West. It was a nightmare driving this thing down south! Ordered this Roadmaster and had it shipped to my friend's house in Florida. We installed it in about an hour and it is a night and day difference. Sway is almost completely gone and you can let go of the wheel and it stays centered. No more white knuckle driving!



by:

Item arrived quickly the video on the site actually helped with the installation and it was very simple, installation is on a 2023 Nexus Wraith 34w on the international MV 670 chassis



by:

The Exact Center Stabilizer itself is very good. The bracket that was sent only worked on one side of vehicle. Instruction say it is universal for either side mounting. That is incorrect for the kit I received. The stabilizer itself would have fit better on my 2022 F53 if it were about 2 inches longer.



by:

It was an easy install...by me,(above average mechanical skill).
You don't need to be a "mechanic" to install yourself, again good directions and web page videos to help.
The unit itself does exactly what is advertised, makes steering a little more "stiff" and centers the steering wheel with little effort.
Great product.
