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.

Honda Odyssey

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.


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!


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.


Auto repair shop had to remove it to get the steering corrected on my motorhome and put the original back on

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



@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.

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!


It’s night and day difference the way my RV handles

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.

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.


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.


Works fine once the installer adjusted it properly.


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

2011 Jeep Grand Cherokee

easy to install on my 2011 e450 super duty jayco grayhawk. test drive proved good control. will know more when towing our jeep grand cherokee.


Made a HUGE difference in ride on our 2021 Sunseeker.
