Features to know about

Better Control on the Highway: Nitrogen-Charged Gas Spring Keeps You Centered

Nothing wears you out faster than fighting the wheel when your rig drifts around in crosswinds or tracks every rut in the road. The Exact Center steering stabilizer uses a nitrogen-charged tandem gas spring that applies full force right when you need it. Instead of reacting after the movement starts, it works proactively to keep steering tight and predictable. The result is a centered, confident feel even when the road or wind wants to pull you off line.

Less Fatigue on Long Drives: Stable, Predictable Handling

When your steering stays where you point it, the drive stops feeling like a workout. This stabilizer prevents your motorhome from wandering, softening the constant corrections that cause arm and shoulder strain on long hauls. You can relax your grip, hold a steady line through wind gusts, and arrive without feeling wiped out.

Built for Heavy Rigs: Heavy-Duty Stainless Steel Construction

Designed for Super C class vehicles, this system is rated for GVWRs of 22,000 lbs and above. The stainless steel build adds strength and corrosion resistance, so it stands up to the weight and vibration of heavy-duty use. Every component is made to handle the loads that standard stabilizers struggle with.

Simple Bolt-On Setup: Custom Mounting Brackets Included

There’s no drilling or welding required. The stabilizer bolts directly to factory axle bracket holes on one end and the tie-rod location on the other. Custom mounting brackets come in the kit, so installation is straightforward with basic tools. Once it’s in place, the improvement in steering feel is immediate.

Video Transcript for Review of Roadmaster Anti-Sway Bars - Steering Stabilizer - RM46MR

Hello, etrailer neighbors. Welcome back I'm Steven. Today we're looking at this Roadmaster exact center steering stabilizer with the custom brackets for your Class A motor homes. Now folks, this stabilizer will prevent your motor home from wandering and help improve the steering. It's gonna help keep your RV centered and it takes the fight out of steering. So if you've ever driven an rv, you know how it is when you get crosswinds, rut tracking, and ride or road edging and stuff.

This helps keep you straight and narrow and it dramatically improves that steering. Now this is a nitrogen charge tandem gas spring, and it applies full force right when you need it. It does help prevent unwanted movement rather than just correcting it after it's begun. Now, the nice thing with this kit is there's no drilling required. You get all the plates, all the U-bolts, hardware, the two bolts.

You even get some lock tide included, and again, you don't have to worry about drilling, it just mounts up in place. It uses your factory axle bracket hole on one end, and then the tie rod location on the other end. So very simple install. You do get, again, the included mounting brackets. Those are powder coated black steel and they're heavy duty made from the USA.

They're not gonna rust or corrode or anything like that. Now this is rated for GVWR of 22,000 pounds and above. Now this will fit your 2022 to 2022 Nexus Ghost Motor Home, MV 607, the 2019 to 23 international trucks MV Series, MV 607, and also the 22 to 23 Nexus Triumph or Wraith Motor Home MV607s as well. Well, folks, that's gonna wrap it up today for our look at this Roadmaster exact center steering stabilizer with the custom brackets. I'm Steven, thank you so much for your time.

I hope this information's been helpful for you. Stay safe out there, have fun installing this. Just take your time, you'll be okay, have a great day.

Do not like how it handles with the center steer



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:

Speaking for myself, and in all honesty from my opinion and with experience using Exact Center Steering Stabilizer. Driving with the ECSS, I’ve found it will be useful on my Jeep being towed. I have several thousand miles on my Jeep, and found city driving okay, but steering you must keep your hands on the wheel. This also goes even more so on the highway. Just returned from a long trip out west to Yellowstone NP, towing a very small camper, and it was very difficult at times when driving only 65-70 mph, with special focus when on the highway when the highway makes direction turns, and really white knuckle both hands on wheel when the road isn’t smooth. As it turns out, on July 2, 2025, I removed the ECSS, and replaced with a normal steering stabilizer, and realize it’s much better, both city and highway driving. I also realize I shot over $400 on something I believed would work better, and I was wrong. The ECSS, may be good when your vehicle is towed, maybe even better on a smooth race track, but on my Jeep, it’s actually unsafe in my opinion and from my experience. I’m thinking more testing is needed, along with additional engineering with adjustments before I would spend that kind of money and knowing it will work first before wasting my money again. Long story short, I had focus on my driving the entire 4000 miles practically with white knuckles way too much, and because of this I missed most of the scenery with is the first time almost thats ever happened. Only bad weather did that before, and a damaged tie rod. I would not recommend the product to anyone, with the exceptions mentioned above. It’s not worth the amount I had to pay, and a mistake buying it. Hopefully you’re honest enough to accept my honesty and truth as I have experienced.
Regards,
Steve

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:

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:

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:

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



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:

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:

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:

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:

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



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:

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



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:

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:

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:

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.

  • What Is Needed To Install The Roadmaster Exact Center RM46MR?
    Hi Jeff, sweet camper! To get the Roadmaster Exact Center Steering Stabilizer w/ Custom Brackets for Class A Motorhomes # RM46MR installed on your 2026 Nexus Ghost 38DS, you will first need to make sure you have the solid front axle. It will not fit if you have the independent suspension up front (some of the International MV607 chassis do have this, but it isn't super common). Once that is confirmed, this is actually a bolt on application and no drilling is required. Some of those bolts...
