Features to know about

Straighter Tracking: Steel Spring Keeps Steering Centered

Nothing’s more tiring than constantly correcting the wheel to keep your rig straight. The tempered steel spring inside this Roadmaster Reflex Steering Stabilizer constantly works to return the steering to center. Whether the front end gets pushed by a gust of wind or jolted by uneven pavement, it pulls back to neutral and keeps you tracking straight without the constant fight at the wheel.

Confidence in Crosswinds: Firm, Controlled Steering Connection

Crosswinds, rut tracking, or even a tire blowout can make any drive unpredictable. This stabilizer mounts between the steering mechanism and chassis for a tight, controlled connection that minimizes wander and corrects oversteering. When you swerve one way, the spring extends or compresses just enough to absorb the motion, then snaps right back to center—steadying the steering and keeping the vehicle composed.

Less Fatigue on Long Drives: Smoother, Easier Control

A long day behind the wheel is much easier when the steering isn’t fighting you. By keeping the wheel centered and absorbing those sudden jolts that cause drift, the Reflex stabilizer helps cut road fatigue. You’re not oversteering or wrestling the wheel through crosswinds or passing traffic, so the ride feels calmer and more predictable from start to finish.

Simple Bolt-On Setup: Mounting Brackets and Hardware Included

This kit comes ready to go with the stabilizer, custom mounting brackets, and hardware for an easy bolt-on install. No drilling or welding is required, and the whole job can be done in about an hour. Once it’s mounted, the steel spring does its job quietly in the background—keeping the steering firm, centered, and reliable mile after mile.

Sure. It pulled and was very heavy on the steering. Had to over correct to keep it stable. Plus it caused heavy jarring when on the road. Husband took it off and all was better. We tried to sell on line but the shipping was too much. Cant you take it back with a discount. It’s just collecting dust

Based on the information so far I know that the steering stabilizer ordered was the incorrect stabilizer for your motorhome. The main stabilizer is the same across vehicles - it is the mounting hardware that changes. I would like to find the correct hardware that you need. I do need to know what the GVWR of the motorhome is and if it has a V10 engine.



by:

A must for anyone who owns a motor home with the Ford F53 chassis.



by:

I had to modify gusset on barcket to clear tie rod, works great on the road.



by:

I have had this product installed for a year now. It has greatly reduced my driving fatigue on long trips.



by:

Why doesn't Ford make this standard on their equipment? This device made my RV so much easier to drive. Driving for six hours is now a pleasant experience versus what it used to be.



by:

It was for a customers motorhome



by:

Handling of the rv is so much better with this bar on. Great investment. Easy to put on we did it ourselves at a campground, took us about 20 minutes.
Don't hesitate to purchase as you won't regret it.



by:

It made driving my late model 37’ ford chassis Motorhome a lot more comfortable



by:

Great product. Great performance. Great dealing with Adam at etrailer.



by:

Great product. I wouldn’t have coach with out it. Handles great in cross winds and when trucks pass



by:

I installed myself. Pretty simple to install. Traveled Utah, Idaho and Wyoming with no issues. Well worth the price and the comfort of traveling. Took the working out of driving a Class A motorhome down the road.



by:

Very happy with all the suspension parts I have received from them fast shipping . I will be ordering more from them in the future .



by:

this works great. installation was easy and adjusting took a couple of tries, crowns in the road and windy conditions didnt help, but driving the coach is much more enjoyable.



by:

Even though I installed the item RMK25-RSSA it did not preform well. The wind blast from sims- trucks would move the RV over, the unit did not recover well.



by:

Works as advertised, installation is straightforward if you follow the installation instructions. Only difficulty encountered was retightening/torquing leaf spring u-bolts to 250 ft/lbs. It’s helpful to have a trained gorilla to handle the torque wrench!



by:

Product fit perfectly, no complaints about that at all.
etrailer’ s customer service is second to none, extremely helpful and knowledgeable not to mention that you talk to a real live person.
The shipping was perfect and on time, not like dealing with the big Amaz— web site where their shipping is not so good or on time.
As it turns out etrailer price is as good or better than the others, so with fantastic customer service, fantastic shipping, access to REAL LIVE people why would you go anywhere else?
I am not being compensated in any way for speaking the truth about my experience with etrailer.com



by:

Had one issue with shipping NOTHING to die with etrailer!! The shipper lost the package, I contacted etrailer on friday and by tuesday I had the missing item. Excellent customer service will continue to shop with them. Ask a question and they will get you an answer. Have an issue they will resolve it. Can’t ask for anything better. Thanks etrailer



by:

After watching a few YouTube videos and reading the fine print of the instructions, I was able to install this steering stabilizer with limited issues. The only problem I had was self-inflicted by overtightening one of the U-bolts because I didn't know how to properly use my new torch wrenches. I was able to find a similar size to replace one of the U-bolts and the stabilizer is working great!



by:

Arrived on time and simple install. It works



by:

I had the steering stabilizer installed. It performs as expected. I am glad I put in on. Now I can drive with less stress.

Works great makes a definite deference



by:

Easy installation took me less than 40 minutes from start to finish. Test drive was a “remarkable” difference than before.



by:

The hardest part is getting the U-boats off and back on again with 250 pounds of torque took me about an hour and I’m 73 years old so I think anybody could do it. We took it out for a test drive and it makes a big difference with the wheel coming back to center, even my wife found it easier to drive. There is know more drifting.

  • Best Steering Stabilizer for a Winnebago Motorhome on a 2018 Ford F-53 Chassis
    Hey Ron, thanks for reaching out! We have two different steering stabilizers for your motorhome on a 2018 Ford F-53 chassis; the Roadmaster Reflex and the Roadmaster Exact Center. The Exact Center was supposed to be an upgrade to the Reflex but after it's release Roadmaster is reverting back to the Reflex because the Exact Center wasn't working out very well. So for your application you'll want to go with the Reflex system that best matches the GVWR of your motorhome: - Up to 24,000...

    The Roadmaster Reflex Steering Stabilizer with Mounting Brackets for Class A Motor Homes # RM-RBK6-RSSA is not the correct fit for your 2018 Tiffin V-10 Motorhome. The # RM-RBK25-RSSA is the correct fit and will correct your fit issue so you will just need the Custom Mounting Brackets for Roadmaster Reflex Steering Stabilizer # RM-RBK25.

  • Recommended Steering Stabilizer For A 2019 Ford F53 Chassis
    Hey Paul-andre, Since you're looking at a steering stabilizer I'm assuming that's what you were wanting? If that's the case then the Roadmaster Reflex Steering Stabilizer # RM-RBK22-RSSA would be a compatible fit for your 2019 Ford F53 chassis as long as its GVWR is under 24,000lbs and it has a V-10 engine. If it has a V-10 engine but is over 24,000lbs GVWR then you'll need the # RM-RBK25-RSSA instead. If you were referring to something else just let me know and I'd be happy to help.

    Without knowing the exact model of your 2014 Thor ACE Motorhome I can only speculate on the correct fitting steering stabilizer. Most likely your motorhome is built on a Ford F-53 chassis like most are, but I'd hate to have you purchase one and it be the wrong fit so you'll want to verify the chassis prior to purchase. If you do have a Ford F-53 Chassis then I have the following recommendations based on the GVWR of the motorhome: For a GVWR over 22,000lbs you'll need the Roadmaster Exact...

  • Difference Between Standard Duty and Heavy Duty SumoSprings on 2019 Newmar Bay Star Motorhome
    Going with a heavy duty Sumo Spring like part # SSR-187-54-1 is going to make the ride quality a lot better on your 2019 Newmar. I would always go with the stronger option because when you hit pot holes or go over curbs the ride quality is going to improve tremendously. Most people add sway bars as well. A sway bar makes the motorhome feel more solid while traveling down a windy road or while changing lanes. Part # RM-1139-149 is the correct rear sway bar for your application. Part #...

This would make a massive improvement in the ride quality of your motorhome.

    Adding a rear sway bar is the route to go. The sway is being caused at the rear of your motorhome because of the weight there as well as the fact you are towing a vehicle.

  • Could Steering Wheel Vibration Be Due To Loose Connections?
    It sounds like there may be some "play" in the suspension parts. If it were pulling right or left, you would loosen the u-bolts pull forward a bit with the wheels straightened, then tighten the u-bolts up again using a torque wrench to the torque recommended in the installation guide. I know you said it was not pulling, but ensuring that the u-bolts are fully tightened is important. Also check all other bolts for proper torque.
