Features to know about

Tighter Control on Every Drive: Nitrogen-Charged Gas Spring Stabilizer

Wandering and rut tracking make it tough to keep your steering steady, especially when the road or wind starts to push back. This Exact Center uses a nitrogen-charged tandem gas spring that applies full force right when you need it, keeping your steering centered and responsive. Instead of waiting to correct movement after it starts, it stops wobble and drift before they happen. That means better control, less fight in the wheel, and a drive that stays pointed where you want it.

Stops the “Death Wobble” Before It Starts: Constant Centering Force

A sudden front-end shake can turn any road into a wrestling match. The Exact Center fights that by constantly working to keep your steering true. Its tandem gas spring resists unwanted motion before it builds up, killing the dreaded “death wobble” and stabilizing the front end the moment bumps or potholes try to throw it off. The result is smoother handling and a calmer ride whether you’re cruising straight or rolling through rough patches.

Better Towing Control: Back Up Without Jackknifing

Flat towing usually means stopping before you ever think about backing up. The gas spring design here makes it possible to carefully reverse your full setup without twisting or bending your tow bar. By keeping the front wheels aligned, it cuts down the chance of jackknifing and protects your gear when you need to reposition. It’s the first setup that actually makes backing a towed rig practical.

Built to Last: Heavy-Duty Stainless Steel and Custom Brackets

Durability is baked in with heavy-duty stainless steel construction and custom mounting brackets. The hardware bolts up cleanly using the factory axle bracket holes on one end and the tie-rod location on the other, so there’s no drilling or welding needed. With a 21" spring length (center of bushing to center of bushing), it’s a straightforward fit that’s designed to hold up through years of use.

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.

@MarkO Anytime, Mark! I'm glad that they were able to get a new one out to you so you could get back on the road!


by:

Used for towing Jeep Wrangler behind motor home. Made Jeep generally unpleasant and a chore to drive. Removed and disposed.



by:

Made a noticeable difference in the steering on the highway.



by:

Installed the product on a 2019 Jeep Wrangler. The vehicle would not maintain lane and when I would try to move the vehicle back to the center of the lane I had to force the steering to move. Had the front end aligned and the problem didn’t go away. The vehicle would also pull to the left and then pull right. I was constantly struggling to maintain the lane. Tried to contact Roadmaster tech support by email, no response. No one answered the phone and the phone would keep ringing. Called customer service, nice person, related there are only 2 tech support persons and they don’t have time to answer the phone. Instructed me to let the phone ring about 15 minutes and I could leave a message. I’ll have to remove it, expensive lesson!

Helped, how ever not the total answer. Can at least feel somewhat comfortable



by:

Installation by qualified shop went smoothly, about 1.2 hours labor. Tracked perfectly so no adjustments needed. Impact on Jeep steering moderate- slightly more force to turn but not a problem. Definitely returns to center more briskly. Looking forward to being able to back up under tow! Will make those gas stations and campgrounds a lot less stressful.

  • Which Roadmaster Steering Stabilizer Should I Use on My 2025 Jeep Wrangler 4xe?
    Hello John, Thanks for writing in. Your 2025 Jeep Wrangler 4xe uses the same JL chassis as the standard Wrangler JL, so both of the Roadmaster Exact Center steering stabilizers you're looking at are designed to fit. If your Jeep is stock or running tires up to 32" in diameter, I recommend the Roadmaster Exact Center Steering Stabilizer # RM99RR. If you have a lift and larger 33" to 37" tires, you'll want the heavier-duty # RM49RR instead. The larger stabilizer is designed to handle the...
