Features to know about

More Control on the Highway: Gas Spring Keeps Steering Centered

Wandering lanes or chasing the steering wheel in crosswinds gets old fast. The Roadmaster Exact Center Steering Stabilizer w/ Custom Brackets uses a nitrogen-charged tandem gas spring that applies full force right when you need it. Instead of reacting after your wheel drifts, it keeps your steering centered the whole time. That means steadier tracking through gusts, ruts, and passing traffic without the white-knuckle grip.

Smoother, Easier Driving: Prevents Wandering and Rut Tracking

This stabilizer takes the fight out of steering by preventing unwanted motion before it starts. It keeps your rig from following grooves in the pavement or edging off the shoulder, so you spend less time correcting and more time enjoying the drive. The result is a relaxed, predictable feel that makes long stretches behind the wheel far less tiring.

Simple Bolt-On Install: Custom Brackets, No Drilling or Welding

You don’t have to modify your chassis to get better handling. The Exact Center mounts using factory axle bracket holes on one end and the tie-rod location on the other. With the included custom brackets, it bolts right up—no drilling, no welding, no guesswork.

Built to Last: Heavy-Duty Stainless Steel Construction

Made from stainless steel and designed for real-world use, the stabilizer stands up to the road’s worst punishment. Its construction resists corrosion and keeps performance consistent mile after mile. Once installed, it’s one of those upgrades you can count on every time you turn the key.

Get responsive steering for your vehicle with this gas spring stabilizer. No more wandering, rut tracking, or white-knucked driving. Custom brackets included.

by:

Good product appears to do what it claims, easy enough to install. I haven't driven it in the wind or with semi truck traffic yet. However the feel is nice as you can actually FEEL the road as opposed to skinning over it



by:

Installation was easy. This product improved the handling of my motorhome.



by:

I have been using the exact center steering stabilizer for several months now. The steering stabilizer improved my steering 10 to 15% leaning towards 10 more than 15. It was relatively easy to install but difficult to adjust due to the fact that adjustments require driving on the highway and adjusting by trial and error. The price is slightly elevated for the worthiness of the product in my opinion. I am not against this product at all. It’s definitely better than Ford’s stock stabilizer, but it’s not a magical fix and should be priced lower.

The product works excellent as long as you buy a track bar for the rear end and larger anti-sway bars. 30 feet of plywood 10 feet tall going down the highway is going to get pushed sideways by trucks and other vehicles no matter how you slice it. The best way to deal with it is to stop the sway first. I still think the price is a little too much for what you get. I think $300 would’ve been a fair price for this product.



by:

only received the stabilizer and no brackets .. so far this is useless



by:

Steering stabilizer was every thing that I had hoped for. Josh was very helpful and courteous. Every item I have ordered from etrailer has been more than expected. All items ordered have been shipped before expected delivery. Etrailer will always be my go to supplier



by:

etrailer the best service (thanks)



by:

My E450 chassis steering was all over the place and it was incredibly tiring to keep the Winnebago in the lane! This product fixed it!! So grateful!!



by:

Great shipping time products as advertise ! Sales person was great also.Will definitely buy from etrailer for my class C motorhome again!



by:

It makes driving a lot more enjoyable. You’re not constantly correcting the steering like you had to with the factory stabilizer.



by:

My customer is extremely happy with the way his RV drives now



by:

I got it installed. I test drove and did the adjustment to get it to drive without pulling to the right and now the coach is driving straight. I am going on a month long trip starting next week but I’m confident it will drive much better than the factory stabilizer. Very happy so far.



by:

Part was an easy installed everything fit as it should. The folks a etrailer are wonderful to deal with, shipping is fast and every body is available for questions if needed. Staff is very helpful. A pleasure to deal with. Thank You

This product has made a huge difference in the drive quality of our RV.



by:

Works as described



by:

Had it installed by a local company adept in RV chassis work. Made a big and appreciated change to handling. Helps to keep the steering sway down to a minimum. Really reduced the effect of passing traffic. Nice



by:

Driving our 30 ft. Class C motor homes, is like driving a sports car, haven’t had steering problems with road ruts, no more white nuckle driving, sure help driving between big
rigs. I glad I waited on them during the Covid shortages instead of buying some other product. You need to put ty raps on the end of the boots that’s keeping it in place. Great investment.



by:

The unit is on a class C motorhome with a Ford E-450 chassis. The factory steering damper could not maintain a stable center in high crosswinds or, for example, when a truck was passing. With the Roadmaster device steering correction is still needed in crosswinds and when some trucks pass the coach but it is a minimal correction compared to the factory damper.

Installation was as simple as described in videos but, the Ford hardware is metric and the Roadmaster is American standard



by:

This steering stabilizer made a noticeable difference while driving my 2018 Forest River Forester Motorhome. The instructions were easy to follow and it didn't take much time to install. I don't have to be on the wheel constantly now as it tracks straight down the highway. Looking forward to many more stress free trips. Highly recommend this product.



by:

I really like the way the vehicle handles after finally getting it centered. I had issues with the rubber boot constantly sliding off one side or the other. This would cause major vehicle pulling one way or the other especially after one heavy rain storm. I placed hose clamps on the boot and clamped it to the steering stabilizer, that fixed the issue.

It has worked very well over the year. No complaints and the clamps work.



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:

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:

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.

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:

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!

  • Steering Stabilizer for 2025 Class C RV on Ford E-450 Chassis
    Hey Kevin! Welcome back. Since you have a 2025 Class C on a Ford E-450 chassis you need the Roadmaster Reflex RV Steering Stabilizer with Mtg Brackets # RM-RBK24-RSSC. This is specifically designed for Class C motorhomes built on the E-450 and includes everything you need for installation. The Reflex will keep you center and remove that play resulting in a much better experience and reduction in road fatigue. If you need anything else don't hesitate to reach out in the comments below.

  • Parts to Improve Ride Quality on 2025 Jayco Greyhawk 27U
    Hi Ed; unfortunately, that is a pretty common problem with new motorhomes. The front and rear anti-sway bar are typically the best way to start so adding the Hellwig Front Anti-Sway Bar # HE26GR is a great idea. After that, I recommend a steering stabilizer. The Roadmaster Exact Center Steering Stabilizer # RM47MR will drastically improve steering and really cut down on fatigue. Since you have the rear anti-sway bar, do you have the JRide Plus package? That comes with the Koni shocks...

  • Roadmaster Anti-Sway Bars For a 2024 Ford E-450 Cutaway Chassis Used on a RV Motorhome
    We have the Front # RM-1139-176 and Rear # RM-1139-147 sway bars to fit the 2024 Ford E-450 chassis under your RV. These are much stronger than any that were installed from the factory and will greatly reduce body roll and sway. I do recommend installing the Roadmaster Exact Center Steering Stabilizer # RM47MR when you install these sway bars as it will greatly improve your steering feel.

  • How To Adjust The Roadmaster Exact Center Steering Stabilizer For A More Comfortable Ride
    The Roadmaster Exact Center Steering Stabilizer w/ Custom Brackets # RM47MR typically comes centered and you would only need to make adjustments after installation and testing to see if it continues to pull. If you adjusted it all the way out to where there wasn't room on the ends to adjust then you went too far. The rods are meant to be slightly adjusted out and then locked back in place with the jam nuts. Roadmaster only recommends turning the rod enough to have the loose jam nut turn...

    Hey Al! The best place to start is with the anti-sway bars. I would add the Roadmaster Rear Anti-Sway Bar # RM-1139-147 first. After that, the front # RM-1139-176 would be the next upgrade. Then to help cut down the wandering and keep you centered I would add the Roadmaster Exact Center Steering Stabilizer # RM47MR. I would add them in that order, it doesn't all have to be done at once, and it is a good idea to start with the rear and see what you think. The best option of course is all...

  • Steering Stabilizer Recommendation for 2019 Ford E-450 Cab and Chassis
    Hey Kevin, we have the Roadmaster Exact Center Steering Stabilizer part # RM47MR that is a fit for your 2019 Ford E-450 Class C. I think the issue was that you had a F-450 cab and chassis truck in our fitguide so the results weren't accurate that you were seeing. The Roadmaster Exact Center setup is the best stabilizer around so this will do a great job improving handling.

  • Recommended Suspension Enhancement For a 2019 Ford E-450 Class C 31' Chassis
    I recommend going with the SumoSprings Front # SSF-106-47 and Rear # SSR-106-47-1 for your 2019 Ford E-450 Class S chassis. I find these provide the support you need without causing a lot of stiffness in the suspension. If you notice your camper has a lot of body roll you can upgrade your Rear Sway Bar # RM-1139-147. And we have the Exact Center Steering Stabilizer # RM47MR to help with the other common problem of steering wandering due to the overhang on the front of Class C RV's.
