Features to know about

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

Long drives shouldn’t feel like a workout. The Exact Center steering stabilizer uses a nitrogen-charged tandem gas spring that applies full force right when it’s needed, keeping steering tight and predictable. Instead of letting your rig wander before correcting itself, this system prevents unwanted movement altogether, so crosswinds, ruts, and road edges don’t have you constantly fighting the wheel.

Confidence Through Wind and Traffic: Keeps You Centered

When gusts or passing trucks push against the body, the stabilizer helps keep everything pointed straight. By holding the steering centered, it maintains control in conditions that usually cause drift or pull. The result is less steering correction and a smoother, calmer experience mile after mile.

Stronger by Design: Heavy-Duty Stainless Steel Build

This is a setup built for the demands of big rigs. The stabilizer’s heavy-duty, stainless steel construction stands up to high-mileage use and harsh conditions without flexing or corroding. It’s engineered for vehicles with a GVWR of 22,000 lbs and above, giving you solid support where it counts.

Simple, Secure Install: Custom Brackets and No Drilling

No need to cut or weld anything. The Exact Center uses factory axle bracket holes on one end and the tie rod location on the other. It comes with custom mounting brackets and all necessary hardware, so the installation is straightforward and solid from the start.

Note

It's important that worn steering components are addressed before installing this kit. If you have a lighter chassis but feel you're pushing the weight limit for a lower-rated steering stabilizer, this heavy-duty Exact Center will work for lighter applications.

Video Transcript for Review of Roadmaster Anti-Sway Bars - Steering Stabilizer - RM92RR

Hello, every buddy. This is Jeff at etrailer.com. Today we're gonna take a look at the Roadmaster Exact Center steering stabilizer with the custom mounting brackets for motor homes. Now this is a custom fit part. It is designed to fit the 2006 to 2018 Freightliner XC Chassis motor homes with the solid front axle. And it will not work on the XCR Chassis.

It will also work on the 2016 and newer Freightliner XC Chassis V-Ride motor home. And again, no XCR Chassis. On a custom fit part like this, I do like to recommend for you to go to our website, use the fit guide. Put in your year, model, vehicle, and it'll show if this will work for your application. Now, this is an exact center stabilizer.

It works better than other steering stabilizer because it's always working to prevent unwanted movement. Whereas the other stabilizers react to movement, this exact center works to prevent it. Other steering stabilizers will slowly activate to control the steering. Only after your motor home has already begun to wonder or make a turn. Basically, other steering stabilizers are reactive which means they fight against unwanted movement but only after the movement has already started.

They'll get your RV back in line and absorb shock while doing so, but they still allow some play in the steering because of their soft centers, which can cause the steering to feel spongy. So this Raodmaster's Exact Center Stabilizers is proactive. It uses a nitrogen charged tandem gas spring on the inside that applies full force right when you need it. This will help prevent the unwanted wondering and the white knuckling that you'll typically get when driving your RV. The stabilizer prevents your motor home from wandering, improves the steering, keeps your RV centered, taking the fight outta your steering.

And it'll help maintain control over your RV during cross winds, rut tracking, and even road edging. It is a bolt on installation. There's no drilling or welding required for installation. Does use the factory axle bracket holes on one end. The tie rod location on the other end includes the mounting brackets or the mounting hardware to install everything. Even has a nice set of instructions. It'll describe how this goes together. Now the stabilizer itself is a heavy duty stainless steel construction. It is made in the USA. Now this is designed to work with motor homes with a gross vehicle weight rating of 22,000 pounds and above. And one last note, as kit is designed to work with a suspension system that is in good working order. But that should do it for the review on the Roadmaster Exact Center Steering Stabilizer with the custom mounting brackets for motor homes..

I installed the Roadmaster Steering Stabilizer RM92RR about 1 year ago. It does help my 2016 Allegro AA drive better. Wind gusts do not push me around as much and I find the RV tracks better and is more relaxing to drive.

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:
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.

Once I got it tuned in, it has performed exactly as advertised! It has kept me from constant steering correction and no white knuckle driving! I have had other steering stabilizers in the past, this one beats them all!

@Scott,W This is really a great product in my experience! What road trips have you taken it on so far?
by:
Nissan Leaf
I was scared to drive my Winnebago before I put this on. I am now driving it with one hand. I took it out to Vegas from Illinois and even though wind will still push the camper to one side or the other, driving was fine. It did take a while to get the nuts off the leaf springs as they were on there pretty good but the rest was easy. It took a few times to get the alignment right.
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:
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.

The Roadmaster Exact Center has definitely been a driving game changer when semi trucks are passing you up.

by:
2018 Winnebago Sunstar LX Motorhome
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.

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:
2015 Ford F-150
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.

Still the very best steering stabilizer I have ever purchased. As annotated in my original review the exact center steering stabilizer has completely eliminated my steering issues on my 2015 Coachmen Encounter 37LS.

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 is awesome, Fred! I'm so glad that we could connect you with Martin Auto. Your kind words are definitely going to be shared with them, I'll make sure of it! It also looks like you have already headed to some great places with the RV, too!

@GwendolynY my Installation was done by a recommended etrailer shop. The installation takes about 40 minutes to connect to the steering rod. Seems simple but tuning and finding the perfect center may take 1-2 hours! It is constant tweaking to get it perfect by a Professional. Jeff Martin is a serious pro! If you want this installation to go right hire a pro. The best way i can explain this installation is it’s like tuning and set Up your instrument for perfect performance!

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 !

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:
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.

I am still very glad I bought this product. It settled down the constant diving into the corners in the mountain roads and has made driving the Class C much safer in my opinion

@CharlesB glad to hear it! It definitely makes a big difference.

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

Joshua did a great job on the phone with me.

The product makes a big difference. Steering is much better, less play, less fighting the steering wheel.

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.

Still havent used it. I just got the motorhome back with a new steering box. It took over a year to find someone that would check out the steering box. The steering box and kingpins were not set up properly at the factory and had to be replaced at 13,800 miles. Im learning what Fix Or Repair Daily means.

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:
2019 Thor Chateau Motorhome
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 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.
