Features to know about

Stay Centered on the Highway: Gas Spring Keeps Steering Tight

No more fighting the wheel when the road wants to pull you around. The Exact Center uses a nitrogen-charged tandem gas spring that applies consistent force to keep your steering centered. It prevents wandering before it starts, so the wheel stays steady in your hands instead of drifting off course. That means a smoother, more predictable feel whether you’re rolling down the interstate or threading through uneven surfaces.

Confidence in Crosswinds: Stabilizer Controls Movement

Strong gusts and passing semis don’t have to throw you around. This steering stabilizer keeps the front end planted by resisting unwanted side-to-side movement. It helps your rig track straight through crosswinds, rut tracking, and road edging without the constant corrections that wear you out. The ride stays level and the steering stays responsive no matter what the conditions throw at you.

Heavy-Duty Build: Stainless Steel for Long-Term Control

Built with heavy-duty stainless steel, the Exact Center is made to handle the demands of large, high-GVWR setups—22,000 lbs and above. The sturdy construction keeps performance consistent over time, so you can depend on it to stay tight and smooth after thousands of miles. It’s a setup built for the long haul, not just the next trip.

No Frame Mods Needed: Installs Using Factory Mounts

You don’t need to drill or weld anything to get solid steering control. The stabilizer bolts to your existing factory axle bracket holes on one end and the tie rod location on the other. Custom mounting brackets are sold separately, but once you have the right kit, installation is straightforward and secure.

Note

Speaking for myself, and in all honesty from my opinion and with experience using Exact Center Steering Stabilizer. Driving with the ECSS, I’ve found it will be useful on my Jeep being towed. I have several thousand miles on my Jeep, and found city driving okay, but steering you must keep your hands on the wheel. This also goes even more so on the highway. Just returned from a long trip out west to Yellowstone NP, towing a very small camper, and it was very difficult at times when driving only 65-70 mph, with special focus when on the highway when the highway makes direction turns, and really white knuckle both hands on wheel when the road isn’t smooth. As it turns out, on July 2, 2025, I removed the ECSS, and replaced with a normal steering stabilizer, and realize it’s much better, both city and highway driving. I also realize I shot over $400 on something I believed would work better, and I was wrong. The ECSS, may be good when your vehicle is towed, maybe even better on a smooth race track, but on my Jeep, it’s actually unsafe in my opinion and from my experience. I’m thinking more testing is needed, along with additional engineering with adjustments before I would spend that kind of money and knowing it will work first before wasting my money again. Long story short, I had focus on my driving the entire 4000 miles practically with white knuckles way too much, and because of this I missed most of the scenery with is the first time almost thats ever happened. Only bad weather did that before, and a damaged tie rod. I would not recommend the product to anyone, with the exceptions mentioned above. It’s not worth the amount I had to pay, and a mistake buying it. Hopefully you’re honest enough to accept my honesty and truth as I have experienced.
Regards,
Steve

This it the second Roadmaster stabilizer I have purchased from Etrailer. Other was for our older 2011 motorhome and after having it I did not want to drive without 1. This is different than prior unit- big factor is so much lighter and easy to adjust, so far working perfectly…



by:

I stopped short of 5 stars because the instructions could be a lot clearer.



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:

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:

The motorhome drives so much easier now. I would recommend this if your on the fence.



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:

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:

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.



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:

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:

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.

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:

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:

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.

HUGE difference. Easy install! Do it!

It's funny I'm writing a review for one of your employees Sherry S. today. I spent most of today dealing with two different phone service companies regarding my cell phone service and have had nothing but a complete nightmare dealing with these two companies' customer service departments. It's been a complete joke and a waste of a lot of my time today. It's not possible in today's world to find anyone in customer service willing to help the customer anymore without speaking a foreign language or spelling out exactly what you need.

On the other hand, my experience of placing an order through your company's website and getting exceptional help from Sherry S. in your service department has changed my outlook. There is hope and Sherry proved it to me. She went out of her way to find a solution to what I needed, then she understood my concerns and most of all she "Listened to Me". Wow! Whatever you're paying this Lady I suggest you give her a raise and don't let her go! She showed me the most impressive customer service I've experienced in 20 years and that's the truth! Sherry, if you ever need a job in Denver then call me. I'll hire you in a heartbeat! I Truly & Sincerely appreciate your help!

Too early to rate the item but the delivery time was awesome!



by:

Easy install and it makes an amazing difference. etrailer has great video tutorial on this. I installed on a Newmar Baystar that was difficult to drive, and made a night and day difference. Took maybe 4 hours including test drives. Be sure to drive before and find the center point on the steering wheel. I hit it the first time so no adjustment needed afterwards. But if needed, the fine adjustments are easy on this compared to the SafeTPlus in was considering.
