Features to know about

Better Control on Every Drive: Nitrogen-Charged Tandem Gas Spring

Nothing takes the fun out of driving like constant wandering or steering that feels loose. The Roadmaster Exact Center uses a nitrogen-charged tandem gas spring that applies full force right when it’s needed. Instead of reacting after steering movement starts, it works to stop it before it happens. You get a tighter, more centered feel and better control even when the road tries to push you around.

Stops “Death Wobble” Before It Starts: Proactive Steering Stability

If you’ve ever felt that violent shake in the steering wheel after hitting a bump, you know how unnerving it can be. This stabilizer keeps the front end planted by maintaining constant tension to hold steering true. Because it’s always working, it prevents the wobble before it can build, keeping things smooth and predictable no matter where you’re headed.

Confident Towing and Backing: Holds Line When Flat Towing

Backing up a flat-towed setup can be nerve-racking when the front wheels want to twist and jackknife. The Exact Center helps keep the tires straight, reducing the risk of tow bar damage and keeping your setup steady. It’s the first stabilizer of its kind that works in reverse too, so you can make careful corrections without disconnecting your tow bar.

Simple Setup: Bolt-On Brackets, No Drilling or Welding

Installing this system doesn’t mean cutting or drilling into anything. It bolts directly to factory axle bracket holes on one end and to the tie-rod location on the other. The kit comes with custom mounting brackets and heavy-duty stainless-steel components built to last. With a spring length of 19-3/8", it’s a precise fit that’s ready to go with the tools you already have.

Built for the Long Haul: Heavy-Duty Stainless-Steel Construction

Every part of this stabilizer is made to handle the miles. The stainless-steel body resists corrosion and hard use, and the limited lifetime warranty backs it up. Once it’s on, you’ll feel the difference every time you take the wheel—steady, centered, and confident.

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.

Do not like how it handles with the center steer

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.



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!



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.

The exact center has performed has been a great addition. The drivability of my 2017 Jeep JKU has been beyond my expectations. The steering while driving has been tight and responsive. I get no wobble when hitting potholes. While towing behind my RV there is no sway and I have had back up a few times and the exact center made that a breeze. One of the best items installed on my Wrangler.



by:

I could not get it center. Even took it to alignment shop and they spent four hours trying to get it aligned to center. They recommended to remove it and not use it. Call road master a couple times but just get voicemail and never got a return phone call.

Sorry to hear that, Sidney. Little surprised as well. These tend to do a very good job, but I have heard they can be difficult to install from time to time. I will see if I can get a response from Roadmaster, but I do have a couple questions. Does your 2014 Jeep Wrangler have stock tires? What size? Is you Jeep lifted? Any other modifications?
