Crosswinds and passing semis can make steering feel twitchy. The tempered steel spring inside the Reflex stabilizer constantly works to keep the steering centered. When the wheel is pushed off course, the spring stretches or compresses to pull it right back to neutral. That tight connection between the steering mechanism and chassis keeps you tracking straight and steady no matter what the road throws at you.
Ruts, uneven pavement, or a sudden tire blowout can jerk the wheel out of your hands. This stabilizer resists those sudden movements by absorbing the force and pulling the steering back into line. Because the spring reacts both when extended and when compressed, it corrects oversteering and helps prevent wandering or drift. You stay in control instead of fighting constant corrections.
Holding the wheel against pull or sway for hours wears you out. With the Reflex stabilizer working to keep your steering centered, there’s less effort needed to maintain a straight line. That means reduced road fatigue and a more relaxed drive, even after miles of highway or winding roads.
Installation takes about an hour with no drilling or welding. The stabilizer mounts to the steering mechanism on one end and the chassis undercarriage on the other using the included custom brackets and hardware. Once it’s bolted in, it’s a clean, solid setup that’s ready to go to work keeping your steering firm and controlled.

Wonderful. E350 passenger van, drive it mostly on vacations from Michigan to Disney. The stabilizer makes a world of difference with straight line stability. No constant steering corrections needed. Long trips are no longer a chore on the driver.

That sounds like it is doing what it is meant to do! I am glad you were able to get it installed somewhere before the weather gets nice. Where is your next big trip to?

Worked great for about 250 miles on my trip to Minnesota but when I was cranking the wheel hard getting out of a gas station I heard a sproing soynd the it was pullu g to the left all the time. Turns out the fixed coller on the shock side sliped about 5 inches,shock itself, not included mounting hardware. I had to remove unit for rest of the trip. Contacted roadmaster and they sent a whole new unit to my sons house and I just installed on the previously mounted hardware and it worked fine with no adjustment. The trip back was great again, and still working great at over 3000 miles later. Thinking about sumo springs for the front but the ride and handling are great with the roadmaster steering stabalizer and my koni evo shocks.

That is awesome to hear! I am glad you were able to feel an instant difference, these make a huge difference in ride quality especially in those bigger motorhomes. New Orleans in January?? What brings you there? I am heading to Lafayette next year for a global music festival with my little pop up.

The stabilizer still works as it should. I have taken my van to trails and still drives straight on the highway. Again I think this is one of the best upgrade I made to the van and surprised the eTrailer have such product when dealers or specialty shops dont even carry it.

It’s been working great. Have take two cross country trips and zero sway from big truckers or high winds.

I still feel this has helped a lot. High winds will be an issue with almost all motor homes. Under normal or 65 or less mph traffic I feel less hassle in steering.

It is so much easier to drive when you can do it in a straight line Kerry =) What kind of camper did this go on, and what trip are you looking most forward to this camping season?

We used it for about 9 months and it made about an 80 improvement in loose steering and wander these old Roadtrek Chevy Express 3500 vans are prone to that. We have since sold the vehicle. It was easy to install. Save your installation instructions. If your front end needs mechanical work, and its not you thats doing it, the product usually has to be removed, and the person doing the work may not know hat to re install it and adjust it.

Its been a year and many miles since I placed this upgrade on our motorhome. Im so happy that I did! If your thinking about this, based on my experience I say do it and dont look back. I believe you will love the difference in steering.

If the vehicle continues to pull to the right or left, the stabilizer can be adjusted to one side or the other as outlined in step 7 of the instruction which Ive linked for you.
