Features to know about

Steady Steering on the Open Road: Nitrogen-Charged Gas Spring Control

Few things drain the fun from a drive faster than fighting the wheel. The Exact Center stabilizer uses a nitrogen-charged tandem gas spring that applies full force right when it’s needed. Instead of waiting for the steering to wander before reacting, it keeps the rig centered and steady from the start. Crosswinds, rut tracking, and road edging don’t throw it off. Every mile feels more controlled and predictable.

Confidence Instead of Correction: Prevents Wandering Before It Starts

Other stabilizers only step in after the steering has already drifted. This one is proactive. It prevents unwanted movement before it begins, cutting out that soft or spongy feel at the wheel. That means tighter, more responsive steering and a true “Exact Center” feel that stays consistent through turns, straightaways, and uneven roads.

Less Fatigue on Long Drives: Controlled, Predictable Handling

Long highway runs don’t have to be an endurance test. By keeping the vehicle centered and reducing sway, this stabilizer takes the fight out of steering. The improved stability reduces how often you correct the wheel, which makes for a calmer, less tiring drive from start to finish.

Built Tough for Heavy Loads: Stainless Steel Strength

With heavy-duty stainless steel construction, the setup is built for serious use. It’s rated for up to 22,000 lbs GVWR and uses a 32" spring length (center-to-center of bushings) for solid, consistent support. The hardware and custom mounting brackets hold everything tight, giving the system long-term durability under demanding conditions.

Simple, Bolt-On Installation: Custom Brackets and No Drilling

Installing stability shouldn’t mean cutting or welding. This unit bolts on using the factory axle bracket holes at one end and the tie-rod location at the other. The custom-fit brackets and included mounting hardware make it a clean, direct install—no frame modifications required, just practical engineering that works.

Video Transcript for Review of Roadmaster Anti-Sway Bars - Exact Center Steering Stabilizer With Bracket Class A - RM58RR

Hi, everybody, Andy here with etrailer.com and today we're gonna take a look at this Roadmaster Exact Center steering stabilizer with custom brackets for Class A motor homes. Now this is going to fit the 1989 to 1999 Ford F53 and F550 class A motor homes with V8 and V10 engines. To confirm that this is going to work for your application, take advantage of our vehicle fit guide here at etrailer.com and input the year, make and model of your vehicle and our fit guide will let you know if this will work for you, or if we have something comparable that will work for you. This gas spring steering stabilizer is going to give your motor home a responsive steering experience that's going to keep your rig from wandering. This works better than other steering stabilizers because it always is working to prevent unwanted movement. It's going to help keep your RV centered, taking the fight out of the steering and help maintain control of your RV during crosswinds, rut tracking and road edging.

This nitrogen-charged tandem gas spring has a maximum gross vehicle weight rating of 22,000 pounds. And it's going to apply full force right when you need it, preventing unwanted movement, rather than just correcting it after it has already begun. So no drilling or welding is needed for installation, it uses factory axle bracket holes on one end and tie-rod location on the other. And as you can see, this does include custom mounting brackets along with the hardware and instructions to guide you along through the installation process. It is important to note that worn steering components should be addressed before installing this kit.

This is made in the USA of heavy-duty stainless steel construction. And as I pull out my tape measure here, I just wanna give you the length here of the spring itself. So measuring center of bushing to center of bushing, as you can see, we are sitting right at 32 inches long and this does have a limited lifetime warranty. Well, that's gonna conclude our brief look today. I do hope that it was helpful for you.

Again, my name is Andy. Thank you for joining me..

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.

Can't wait to get on the road and try it out. After installing this now I understand the whole theory of how this stabilizer will improve the driving experience. I also noticed during installation the previous owner of the coach must have had one installed as well due to the nuts on the leaf springs showing evidence of being removed recently. I did have to grind off the corner of the black bracket that comes with the kit and give it a bigger radius as the axle was flat in that corner. See picture for a better understanding.Just a 5 min setback so nothing difficult. Will come back and update after a test drive.2001 Fleetwood Southwind 37U on a F53 chassis.



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:

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:

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:

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



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:

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:

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:

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:

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:

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 installation is pretty much straight forward. The written instructions are a little on the vague side, but the installation videos help with the details. I haven't taken a trip yet, but will in a couple of weeks. I'm looking forward to not having to fight the steering wheel.



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:

Naomi D was instrumental in figuring out which steering stabilizer would work for our motorhome. We were thankful for the quick shipping and delivery. I truly liked how we were given a list of people who took care of our order, even with pictures! A nice personal touch! The installation went well and we only had one small adjustment to make after driving it a little bit. The instructions were very helpful. Thank you so much!



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.



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

MADE MY F53 DRIVABLE.



by:

Made a big difference in how well the RV handles. Installation was simple. One full turn on the adjustment makes a big difference so use 1/2 turn or less each time until you get it set right.
