  • Stabilizer prevents your vehicle from wandering and improves steering
    • Keeps your rig centered, taking the fight out of steering
    • Helps maintain control during crosswinds, rut tracking, and road edging
  • Nitrogen-charged tandem gas spring applies full force right when you need it

  • No drilling or welding needed for installation
    • Uses factory axle bracket holes on one end and tie rod location on the other
    • Includes custom mounting brackets
  • Heavy-duty, stainless steel construction
  • Made in the USA
  • Limited lifetime warranty


Note: It's important that worn steering components are addressed before installing this kit.


Exact Center vs. Other Steering Stabilizers

The Exact Center works better than other steering stabilizers because it's always working to prevent unwanted movement.


Where other stabilizers react to movement, Exact Center works to prevent it

Other steering stabilizers slowly activate to control steering only after your vehicle has already begun to wander or make a turn. Basically, other steering stabilizers are reactive - they fight against the unwanted movement, but only after the movement has already started. They will get your rig 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.


Exact Center uses a nitrogen-charged tandem gas spring to apply force right when you need it

Roadmaster's Exact Center is proactive. It uses a nitrogen-charged gas spring that applies full force right when you need it. This helps prevent the unwanted wandering and white-knuckling you typically get when driving your vehicle. The improved responsiveness makes driving to your next adventure less of an exhausting chore.

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:
2020 Jayco Redhawk Motorhome

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.



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.

Great product, fast shipping. Follow up as soon as I use stabilizer.

took off. liked the reflex better but could not return center steer. still have it. too much steering wheel movement over cracks and bumps.



by:

make sure steering wheel is straight before you start. test drive was vastly improved. almost no wander. my roads suck in the country, so its really hard to tell how good until i get on a real highway.



by:

Installation was easy. Only had to adjust it a couple
times to get it dialed in. The motorhome handles a lot better now.



by:

I can always count on e trailer for the right part at a good price. In addition, their product knowledge and customer service is outstanding.

It is unusual that the stabilizer did not help driving the motorhome. Did the auto body shop point to the stabilizer as being problematic?

Russell

@JennyN The rv was taken to blue hen spring works . The motor home was a ford chassis E-450 . It was a white nuckle driving experience to bring it home from Florida on I-95 . Mini vans going by would blow me off the road and pot holes would yank the steering wheel out of your hands . So I purchased the steering damper to hopefully help , but did not make any difference. The Rv dealership was no help and told me to take to a ford dealership. They could not help recommend Barr international who works on big trucks No help. Finally went to blue hen spring works they adjusted the caster and did front end alignment. When they test drove it the service manager said it was way better and wanted to put stock unit back on and made the rv drive normal . It was a amazing difference

@Russell I really appreciate the information. Since you are not using it, I would suggest selling it locally. I am happy to send over a list of vehicles that it fits to you.

I added this Roadmaster exact center stabilizer to my 2022 Entegra Odyssey 26M class C RV and it was a game changer. I felt like I was driving a car i didn’t have to keep making huge adjustments with the steering wheel and it helped so much when pass Semi trucks. It also helped on roads that were rutted. I didn’t feel like I was going all over the road. I think that the combo of this stabilizer and the Sumo Springs that I added to the bump stops on the frame (1000 lb front springs, 3000 lb rear springs) have made RV travel way more enjoyable. No more white knuckle driving.



by:

Suggest this is one of the first steps ever new class c owner do to replace the OEM component. The OEM component on my unit was complete trash with less than 5K miles.



by:

Made such a big difference when doing our c class motorhome. We definitely recommend your company with getting this Roadmaster .

Ford F-150

Delivered on time. Great videos available for installation. It may have taken a half hour to install. I bought this for a 2021 Cross Trek 22XG on E350 chassis. It made a big difference. It's not like driving my F150, but with this set up I'm 90% there. So instead of having to concentrate on staying in my lane so much I could actually enjoy the scenery! Game changer!



by:

installed myself. could not get adjusted right. took rv to two different well known sales shops and they could not get it adjusted correctly either. has helped some but cannot recommend this product



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.



by:
2019 Entegra Coach Odyssey Motorhome

Very easy to install and does what it says it will do. Easier to handle on the road now. No problem with the wind.



by:
2017 Forest River Forester Motorhome

I love this product. I would have installed it sooner, but I needed to find a video of someone installing a bracket on my style C-Class. I wasn't sure if there was a nut on the inside of the frame. An install demo would be helpful on this one for Ford C-Class.



by:
2017 Winnebago Aspect Motorhome

After being blown all over the highway on a windy day in my 2012 Winnebago Class-C, I decided to purchase Roadmaster Anti-Sway bars and steering stabilizer. The sway bars and stabilizer were a perfect fit for the 2011 Ford E-450 chassis. After having the parts installed, I immediately felt a remarkable difference in the way my 30' RV handled. I can now drive down the highway without a fear of being sucked into big rigs or being pushed into the next lane under windy conditions. This "Exact Center Steering Stabilizer" does exactly what it says, it helps keeps you centered as you drive down the highway. Well worth the money!

Seems to be high quality. Very easy to install and adjust. THE PICTURES IN THE DIRECTIONS COULD BETTER. I haven't tested on freeway. Stabilizer is installed on 2023 Ford E350 classC motorhome.

  • Steering Stabilizer and Rear Sway Bar for 2011 Itasca Cambria E-450
    A Roadmaster steering stabilizer like the Exact Center part # RM47MR is going to fix the wandering issue you are having and is exactly what you are looking for from your 2011 Itasca Cambria built on a Ford E-450 chassis. Before I would do a set of SumoSprings a rear sway bar like the Roadmaster part # RM-1139-147 would be what I recommend. For motorhomes the biggest and best improvement you can make to the ride quality and stability is with a rear bar like Roadmaster I mentioned.

It's important that before you install this that your alignment is correct.

I use the parking spaces to gauge if I'm going straight when I test for this.
