Features to know about

Steadier Highway Control: Gas Spring Keeps You Tracking Straight

Tired of constant corrections when crosswinds or passing trucks push you around? The Exact Center uses a nitrogen-charged tandem gas spring that applies full force right when you need it. Instead of waiting for the vehicle to wander and then correcting, it works proactively to keep you centered. The result is a solid, predictable steering feel that takes the fight out of keeping your rig in its lane.

Less Fatigue on Long Drives: Responsive, Centered Steering

When the wheel wants to drift, every mile feels longer. This stabilizer keeps the steering tight and on center so you’re not chasing the wheel all day. By cutting out rut-tracking and lane wander, it makes long drives less of a workout. You stay relaxed, the steering feels consistent, and you arrive fresher and more comfortable.

Built for Strength: Heavy-Duty Stainless Steel Construction

A stabilizer that works this hard has to be built to last. The heavy-duty stainless steel body resists corrosion and holds up to real-world miles. The design uses tough internals that deliver reliable gas-spring action without soft spots or spongy steering. It’s built for long-term stability and confident handling.

Simple Bolt-On Install: Custom Brackets, No Drilling Required

You don’t need to cut or weld to get the benefits. The kit includes custom mounting brackets and uses existing factory holes—one on the axle bracket, the other on the tie-rod location. With mounting hardware included, the install is straightforward, and you’ll be back on the road quickly with a tighter, more controlled drive.

Exact Center Feel: True On-Center Stability

The name says it all. By giving your steering a defined center point, the system delivers a sports-car-like feel that makes control instinctive. It prevents unwanted movement before it starts, improving both safety and comfort on every stretch of road.

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.

by:

I wish I had installed the stabilizer years ago. My motorhome is so much easier to drive.
A great product.



by:

Easy to install



by:

Recent easy install time will tell if it works as advertised.
