7 Jack Stabilizer Bars For Windy Conditions That Nomads Swear By

There’s nothing quite like being parked in a beautiful spot, only to have a 30-mph gust of wind turn your peaceful home into a rocking ship on the high seas. That constant, unnerving sway isn’t just an annoyance; it’s a sign that your rig’s foundation is fighting a battle it can’t win alone. The secret to a rock-solid feel, even when the weather turns nasty, lies in transforming your simple landing gear into a rigid, triangulated structure.

Why Wind Makes Your Jack Stabilizers Crucial

When you park your RV, you extend jacks to lift the weight off the tires and suspension. This creates a stable platform, but it’s a platform with a hidden weakness: lateral force. Your jacks are designed to handle vertical loads, but wind pushes against the massive, flat side of your rig, introducing side-to-side and front-to-back motion.

This movement translates directly inside. Every step you take, every gust of wind, creates a wiggle that travels through the frame. Over time, this isn’t just uncomfortable; it puts cumulative stress on your jack legs, welds, and the RV’s frame itself. It’s the difference between feeling like you’re in a house and feeling like you’re in a temporary shelter waiting for the storm to pass.

Jack stabilizer bars solve this problem with simple geometry. By adding bars that connect the jack legs to the RV frame, you create a series of rigid triangles. A triangle is the strongest shape in engineering, and it effectively eliminates the pivot points that allow your jacks to wobble. This triangulation is the key to turning your rig from a wobbly box into a solid foundation.

Lippert JT’s Strong Arm Jack Stabilizer Kit

The JT’s Strong Arm is one of the most recognized names in the RV stabilization game, and for good reason. It’s a permanent, bolt-on system designed to integrate directly with your existing landing gear and stabilizer jacks. The kit includes several telescoping steel tubes that form those crucial triangles on both your front and rear jacks.

Once installed, using them is incredibly simple. After you level your rig, you just loosen the T-handles on each arm, let them extend, and then re-tighten them. That’s it. This convenience is a massive selling point for full-timers or anyone who moves frequently. You never have to store them or get them out of a bay; they’re always right where you need them.

The tradeoff for this convenience is the installation. While not overly complex for someone comfortable with tools, it does require drilling into your RV’s frame, which can be intimidating for some owners. It’s a commitment. But for those who want a "one and done" solution that dramatically reduces side-to-side and front-to-back sway, the Strong Arm system is a proven, heavy-duty performer.

The SteadyFast System for Ultimate RV Stability

The SteadyFast system is the other heavyweight contender in the permanent, bolt-on stabilizer market. It operates on the same principle of triangulation as the JT’s Strong Arm but achieves it with a slightly different, and some would say more elegant, design. Instead of individual arms on every jack, SteadyFast uses a unique three-point system.

Two arms brace the front landing gear, and a single, long arm braces one side of the rear jacks. All three points are then tightened with a single wrench at one central bracket. This design is brilliant because it reduces setup time at the campsite; instead of tightening four or six T-handles, you tighten one single bolt. It makes an already convenient process even faster.

Like its main competitor, the SteadyFast requires a permanent, bolt-on installation that involves drilling. The decision between SteadyFast and JT’s Strong Arm often comes down to personal preference. Do you prefer the simplicity of a single tightening point, or the redundancy of individually tightened arms? Both are top-tier systems that will transform the feel of your rig in windy conditions.

MORryde X-Brace for Fifth Wheel Campers

If you have a fifth wheel, you know the front end is where most of the wobble originates. Those long, independent landing gear legs are the primary culprits. MORryde, a company known for its suspension and pin box upgrades, tackles this problem head-on with their X-Brace stabilizers.

This system is specifically designed to create a rigid ‘X’ between the two front landing gear legs. It directly counteracts the lateral forces that cause that pronounced side-to-side shimmy you feel in the bedroom area. The installation is straightforward, and a simple lever or turnbuckle applies tension, locking the two legs together.

While the X-Brace is fantastic at what it does, it’s important to understand its focus. It primarily solves the front-end wobble. For a truly locked-down feel, many nomads pair a front X-Brace system with rear stabilizers or even a full system like the JT’s or SteadyFast. Think of it as the most effective first step you can take to stabilize a fifth wheel.

Ultra-Fab Eliminator: A Universal Stabilizer

Not every rig is a massive fifth wheel, and not every owner wants a complex, model-specific kit. This is where the Ultra-Fab Eliminator shines. It’s a more universal, telescoping stabilizer system designed to work with a wide variety of jack types, from scissor jacks on a travel trailer to the landing gear on a smaller fifth wheel.

The Eliminator functions on the same triangulation principle, using adjustable steel tubes to connect your jacks to the frame. Because they are designed to be universal, they often come with a variety of brackets and hardware to adapt to different setups. This makes them a versatile and often more budget-friendly choice.

The user experience is solid and functional. While the setup might lack the integrated polish of the premium systems, the end result is undeniable: a much more stable RV. For the RVer with a travel trailer or an older rig, or for someone who wants a robust, bolt-on solution without the premium price tag, the Ultra-Fab Eliminator is a workhorse that gets the job done.

BAL Lock-Arm: A Bolt-On Stabilizing Bar

BAL is a giant in the world of RV jacks and leveling, so it’s no surprise they have their own excellent stabilizing solution. The BAL Lock-Arm is another permanent, bolt-on system that competes directly with the likes of Lippert and SteadyFast. Its goal is the same: create rigid triangles to eliminate movement.

The Lock-Arm’s unique feature is its patented locking mechanism. Once you’re leveled, you flip a lever, and the arm locks into place, bracing the jack against the frame. It’s a simple, positive-locking system that’s easy to engage and disengage. For those who already have BAL jacks or other BAL products, sticking with the same manufacturer can ensure seamless compatibility and a perfect fit.

Ultimately, choosing the BAL Lock-Arm often comes down to brand trust and specific application. It is a well-engineered, reliable system that performs exceptionally well. It proves that while the principle of triangulation is simple, there are multiple high-quality ways to achieve that rock-solid feel.

Valterra Universal RV Stabilizer Bar Set

What if you’re not ready to drill holes in your brand-new RV’s frame? Or maybe you have a smaller travel trailer and just want something to help on those extra windy weekends. The Valterra Universal RV Stabilizer Bar Set is a perfect example of a non-permanent, portable solution.

These are essentially adjustable bars that you put in place after you’ve set up your rig and remove before you leave. One end typically cups the jack leg, while the other braces against the frame, held in place by tension. You set them up at camp and store them in a bay when you travel.

The major benefit here is the lack of commitment. There’s no permanent modification to your RV, and you can easily take them with you to your next rig. The downside is that it’s one more task during setup and teardown. For the part-time RVer or someone testing the waters of stabilization, this is an excellent, low-cost way to get a significant reduction in wobble without a permanent installation.

Stromberg Carlson Landing Gear Stabilizer

Stromberg Carlson offers another fantastic, targeted solution for the wobbly front end of a fifth wheel. Their Landing Gear Stabilizer is a simple, robust cross-brace that functions much like the MORryde X-Brace. It’s designed to do one thing and do it exceptionally well: stop side-to-side motion at the front of the coach.

The system typically consists of two telescoping arms that clamp to each landing gear leg, meeting in the middle at a large, easy-to-use turnbuckle. After extending your landing gear, you simply tighten the turnbuckle by hand, and it cinches the two legs together, creating an incredibly rigid A-frame structure.

This product is a nomad favorite because of its simplicity and effectiveness. The installation is often tool-free, and the impact is immediate and dramatic. While it won’t eliminate rear-end wiggle, it tackles the most annoying motion on a fifth wheel. For many, this single addition provides 80% of the desired stability for 20% of the cost and effort of a full-rig system.

Ultimately, choosing the right stabilizer isn’t about finding the "best" one, but the right one for your specific rig, travel style, and budget. Whether you opt for a permanent, fully-integrated system or a simple, portable cross-brace, the goal is the same: to transform your home on wheels from a vessel tossed by the wind into a solid, unshakeable foundation. That feeling of stability, when the world is blowing outside, is worth every penny.
