6 Best Heavy Duty Shock Stabilizers For Large Fifth Wheels Nomads Swear By

You hit that unexpected bridge transition on I-80 a little too fast and the whole world seems to explode behind you. The fifth wheel launches, cabinets fly open, and you spend the next ten minutes wondering what broke this time. If this sounds familiar, you’ve experienced the brutal reality of a stock RV suspension trying to manage the weight of a heavy, full-time home on wheels.

Why Heavy-Duty Shocks Matter for 5th Wheels

Stock suspensions on most fifth wheels are designed for a price point, not for the punishing reality of thousands of miles on varied road surfaces. They typically use a basic leaf spring setup with no shock absorbers at all. This means every bump and dip in the road sends an undamped shockwave directly into your rig’s frame.

Think of it like this: your leaf springs absorb the initial impact, but without shocks, they just keep bouncing. This uncontrolled oscillation is what shakes your RV apart over time. It loosens screws, cracks welds, and sends your belongings tumbling.

Upgrading your suspension isn’t a luxury; it’s a necessity for protecting your investment and your sanity. A good shock and stabilizer system dampens that oscillation, turning a violent jolt into a firm, controlled movement. The result is less stress on the frame, less wear and tear on appliances and cabinets, and a significantly less fatiguing tow for you.

MORryde IS System: The Ultimate Smooth Ride

If you’re looking for the absolute best ride quality and money is a secondary concern, the MORryde Independent Suspension (IS) is the answer. This isn’t just a shock absorber; it’s a complete replacement of your axles and leaf springs with a fully independent suspension system, similar to what you’d find on a modern car. Each wheel reacts to the road on its own.

The difference is night and day. With over five inches of wheel travel, the IS system soaks up potholes, expansion joints, and rough pavement like they aren’t even there. We’re talking about finding your coffee cup still on the counter after a long travel day. It dramatically reduces the transfer of road shock to the chassis, which is the single best thing you can do for the longevity of your fifth wheel.

The major tradeoff is cost and complexity. The MORryde IS is a significant investment, often costing several thousand dollars, and it requires professional installation, typically at the MORryde facility in Indiana. For full-time nomads who put serious miles on their rig and plan to keep it for years, many find the cost is justified by the unparalleled ride and protection it provides. It’s a foundational upgrade that transforms the entire towing experience.

Roadmaster Comfort Ride Shocks for Towables

For those who want a major improvement without a full suspension transplant, the Roadmaster Comfort Ride system is a fantastic, targeted solution. This kit adds gas-pressurized shock absorbers to your existing leaf spring suspension. Its primary job is to control the rebound of the springs, effectively killing the bounce that plagues so many heavy trailers.

The system works by mounting shocks longitudinally, one on each side of the axle. This setup is specifically engineered to counteract the up-and-down motion that causes "chucking" and "porpoising." You’ll feel the difference immediately on undulating highways and concrete roads with rhythmic expansion joints. The trailer settles down quickly instead of continuing to bounce long after the bump is gone.

Roadmaster’s kit is a bolt-on solution, making it accessible for a skilled DIYer or a straightforward job for any RV service center. It’s a powerful middle-ground option that delivers a huge percentage of the benefit of a more complex system for a fraction of the cost. It directly addresses the most common complaint—the violent bouncing—and does it exceptionally well.

Lippert Road Armor: A Robust Suspension Upgrade

Lippert’s Road Armor system is another excellent integrated upgrade that improves upon the stock leaf spring setup. It combines a heavy-duty equalizing system with a set of shock absorbers. The equalizer is the heart of the system, pivoting to transfer weight between the axles as you go over uneven terrain, which keeps the trailer more level.

The shocks then work in tandem with this improved equalizer to dampen the spring movement. This one-two punch results in a significantly smoother and more controlled ride. The Road Armor equalizer provides three inches of vertical travel, which is a big step up from the stock components and helps absorb rough road conditions before they reach the frame.

This system is a great choice for RVers looking for a comprehensive upgrade that addresses both load distribution and shock absorption. It’s more involved than a simple shock-only kit but less complex and costly than a full independent suspension. Many nomads see it as the sweet spot, offering a robust, tangible improvement in ride quality and stability that you can feel in the driver’s seat.

Joy Rider Shock System: Taming Highway Bounce

The Joy Rider system is another popular shock absorber kit that gets rave reviews from the full-time community. What sets it apart is the mounting design. The shocks are mounted at an angle, which allows them to control not just vertical motion but also some of the side-to-side forces that contribute to a shaky, unstable ride.

This angled approach is particularly effective at taming highway bounce and the jarring impacts from things like railroad tracks and bridge transitions. By resisting both up-and-down and lateral forces, the Joy Rider system helps keep your tires planted firmly on the pavement. This translates to better tracking and a more secure feeling, especially in windy conditions or when being passed by large trucks.

Like the Roadmaster kit, this is a bolt-on system designed to work with your existing suspension. It’s a direct and effective solution for the most common complaints about fifth wheel towing. For many, the Joy Rider provides that "ah-ha" moment where they realize their trailer can, in fact, ride smoothly without shaking itself to pieces.

SumoSprings: Reduce Sway and Stabilize Your Rig

SumoSprings offer a different approach to suspension enhancement. They aren’t traditional shocks; they are proprietary micro-cellular urethane "helper springs" that mount between the frame and the axle. They are designed to engage as the suspension compresses, providing progressive resistance to limit travel and reduce sway.

The beauty of SumoSprings is their simplicity and maintenance-free operation. There are no seals to leak or gas to lose. Once installed, they just work. They excel at reducing body roll in turns and minimizing the push you feel from crosswinds. While they do dampen some vibration, their primary role is stabilization.

Many RVers use SumoSprings in conjunction with a shock absorber system for the ultimate combination of control. The shocks handle the high-frequency bouncing, while the SumoSprings manage the larger, slower movements like swaying and rolling. If your main complaint is feeling top-heavy or unstable, SumoSprings are an excellent and cost-effective first step.

MORryde X-Factor for Frame Stiffness and Support

This one isn’t a shock, but it’s a non-negotiable part of any serious suspension upgrade. The MORryde X-Factor is a heavy-duty crossmember that bolts between the suspension hangers on opposite sides of the frame. Its sole purpose is to prevent the frame rails from flexing and the hangers from cracking under stress.

A flexing frame will undermine the performance of any shock or suspension system you install. The suspension hangers are a known weak point on many fifth wheel frames, and a failure here can be catastrophic. The X-Factor provides immense lateral support, locking the hangers in place and ensuring the force from the road is directed into the suspension components, not into twisting your frame.

Installing an X-Factor crossmember (or two, for a triple-axle setup) is one of the smartest preventative maintenance upgrades you can make. It’s relatively inexpensive and easy to install, yet it provides the rigid foundation your shocks need to do their job effectively. Many seasoned nomads won’t hit the road without one.

Choosing the Right Stabilizer for Your RV Setup

There is no single "best" solution; the right choice depends on your specific rig, budget, and the problems you’re trying to solve. The key is to correctly diagnose your issue before throwing money at it. A good framework for deciding is to consider your primary complaint.

• If your main problem is violent bouncing and chucking: Start by looking at a dedicated shock kit like the Roadmaster Comfort Ride or Joy Rider. These are designed specifically to tame that uncontrolled oscillation.
• If your issue is sway, body roll, and a top-heavy feel: SumoSprings are your most direct and effective solution. They are excellent at stabilizing the rig against lateral forces.
• If you want a comprehensive upgrade for a smoother, more controlled ride: The Lippert Road Armor provides an excellent balance of equalization and shock absorption at a reasonable price point.
• If you want the absolute best ride and plan to keep your rig for the long haul: The MORryde IS System is the ultimate goal. It solves every problem but comes with the highest price tag.

Don’t forget the foundation. Regardless of which system you choose, installing a MORryde X-Factor crossmember is a critical first step. It ensures your frame is strong enough to support the improved suspension. Many of these systems can also be combined. A popular and highly effective setup is pairing the Lippert Road Armor with an X-Factor and even adding SumoSprings for maximum stability. Assess your needs, start with the most critical component, and build from there.

Upgrading your fifth wheel’s suspension is one of the most impactful changes you can make to improve your travel experience. It moves beyond simple comfort and becomes about protecting the structural integrity of your home on wheels. By choosing the right system, you’re not just buying a smoother ride; you’re buying peace of mind for every mile ahead.
