Highlights
- Custom Fit for Your Vehicle: Tuned to your suspension for better control and stability.
- Keeps Steering Straight: Steel spring constantly works to return steering to center for steady tracking.
- Handles Crosswinds: Tight link between steering and chassis helps control sway and wander in gusts or blowouts.
- Less Driver Fatigue: Stabilizer keeps you centered so you don’t fight the wheel on long drives.
- Improves Oversteering Control: Spring pushes or pulls back to neutral when steering is turned too far.
- Simple Bolt-On Install: Includes stabilizer, custom brackets, and hardware—no drilling or welding required.
Features to know about
Straighter Tracking: Reflex Spring Keeps Steering Centered
When gusts, ruts, or uneven roads try to pull you off line, the Reflex stabilizer fights back automatically. Its tempered steel spring constantly works to bring the steering back to neutral—pushing when compressed, pulling when stretched. Mounted between the steering linkage and chassis, it creates a solid connection that minimizes wander and oversteering. The result is steadier tracking and less steering correction when the road gets unpredictable.
More Control in Crosswinds and Emergencies: Firm, Predictable Steering Feel
Crosswinds, road edging, or even a front-tire blowout can throw off your course fast. This stabilizer helps keep steering firm and centered so you stay in control when it matters most. The steel spring resists drift in either direction, keeping the front end from darting off line. That built-in resistance makes the wheel return naturally to center instead of fighting you, giving a calmer, more predictable driving feel in rough conditions.
Less Fatigue on Long Drives: Steering That Stays Put
Constantly correcting the wheel on a long haul can wear you out. With the Reflex stabilizer in place, the spring does the small corrections for you. It keeps the steering centered so you don’t have to work as hard to stay between the lines. That steady tracking reduces the mental and physical fatigue that comes from chasing the wheel mile after mile.
Quick Install: Custom Brackets and Hardware Included
No drilling or welding needed—everything you need comes in the box. The kit includes the stabilizer, custom mounting brackets, hardware, and installation instructions. It bolts up in about an hour using standard tools, so you can get back on the road with a safer, more stable setup.

This installed in less than an hour, 2006 Monaco La Palma Roadmaster Chassis. I used a 1/2 cordless 1100 Ft lb. impact to remove the spring u-bolts, came right off. The rest is as the instructions say. I took for a road test and drives a straighter. etrailer shipped and I had in a couple of days. etrailer is the best for me. Tools for this is 1/2 drive 15/16 deep socket for the axle U Bolts, 3/8 drive 3/4 inch for the shock bolts and a 3/4 open end wrench, and a 3/8 drive 9/16 deep socket for the tie rod U Bolts. Easy to do yourself.

-- This stablizer was installed on a 07, Monaco Camelot, with a Dana Axle, & air bags -- Your web site states that the RBK6 will not fit a Dana axle -- I called Roadmaster, & they said it will fit, & it does --The The steering stablizer install was not a tough job at all -- The only problem was loosening the nuts that hold the axle, & the bolts not being long enough to add the bracket -- I do have air tools, & I heated the nuts with a plumbers tourch -- It took longer to free the the nuts, that it took to do the rest of the install -- On the test drive, no adjustment was needed -- Very pleased from order to install -- William Willard

Hey George, After speaking with your sales team I was kinda concerned this item was going to be backordered but was surprised with your prompt processing. I muscled this beefy steering stabilizer on in a little over an hour without any special tools (other than a cheater bar). I'm still waiting to road test it but don't anticipate any problems.
Thanks!
Thanks!

The purpose of controlling cross winds, trucks passing etc, this product works perfectly. However I did have a failure of the shock assembly. Something failed on the end of the tub causing the bracket to bend (not come off) then I had a strong pull to one side. Took it back to where it was installed. After examination and calling Roadmaster, a new unit is being shipped to and will be re-installed by a local RV retailer. Both Roadmaster tech support and warranty were great to work with as was/is the RV retailer. I will have to pay to install again as the labor is not warranted by either Roadmaster or the retailer, because I did not buy from them. However, I save considerably by buying from etrailer.

I replaced a generic sway bar a previous owner had installed with this one which is designed for this chassis. The difference was night and day - no more sawing wood down the highway. Drives like a pickup truck now and tracks nicely even when being passed by semi's. Great service form E trailer - as always

Received the part in three business days and installed the part in about an hour, on my Raodmaster RV chassis, including reading instructions and tuning. The stabilizer dramatically improves the steering creating a steering wheel experience similar to my late model Ford F150. It also reduces the anxiety of a high speed front tire blowout as it provides substantial turning resistance; certainly hoping so, heaven forbid.

Product is robust, mounting brackets are substantial. Installation can be a challenge - removing suspension u-bolt nuts can tax even a powerful impact gun, even after soaking with WD40. After that the unit installs easily. After a couple test drives I can definitely attest to the improvement in steering stability, much less tendency to track ruts in the roadway. Worth the investment.

The kit was easy to install, but definitely need an impact (1/2" drive) and a torque wrench (250 lb). Aligned the wheels carefully & we installed correctly the first time.
Made an immense difference in handling & control! My son-in-law, who assisted me, was absolutely astonished about the difference. I was anticipating a difference & am so very happy with the result.
etrailer has a very fair price and delivered quickly. Thank you Roadmaster and thank you etrailer.com. Only disappointed in that I can't leave right now on a long trip!

Received the Roadmaster RSSA yesterday and installed it today on my 2007 Holiday Rambler Diesel Pusher motorhome. The install went without a hitch. The directions were complete and easy to follow. I took a short test drive after installation and the unit seems to perform as promised. There was much less steering correction required with a stiff cross wind. I look forward to taking a long trip as soon as possible.

The steering stabilizer was easy to install, took less than 20 minutes. The motorhome is a lot easier to drive and large trucks do not effect the motorhome like they did before the stabilizer was installed.

Received my stabilizer and mounts RBK6 within 3 days of placing order. All parts and directions were in the box. I was able to install it on my 1999 Monaco diplomat within a few hours. Would have went quicker but getting the nuts off the chassis was very difficult (they were on very snug). Installed finally and took motorhome for road test and the difference is amazing. Thank you etrailer for satisfying my order so quick!

- Which Steering Stabilizer Will Fit a 2005 Beaver Monterey to Correct Steering ProblemsTo help with your steering issue you're going to need a Roadmaster Reflex Steering Stabilizer.

Works very good, but the attachment bracket failed after 10 mo., 6000 miles. Road master replaced the stable service but I had to pay another $100 plus to remove and replace.
