The Kohree 7500lbs Scissor Jacks are a robust solution for campers seeking serious stability. Constructed from heavy-duty steel with an electrophoresis coating, these jacks are built to withstand the elements and provide long-lasting support. I found their wide bow-tie base especially effective at distributing weight and preventing sinking on softer ground.

The ability to use a power drill is a huge time-saver, especially after a long drive. Just remember to use them for stabilization, not for lifting the entire RV off its wheels.

Designed specifically for RVs and travel trailers, each jack boasts a 7500 lbs support capacity while being surprisingly lightweight thanks to its corrosion-resistant aluminum construction.

The LUSHIH RV Slide Out Support Jacks are specifically designed to address a common pain point for RV owners: wobbling slide-outs.

Expert Opinion: These jacks are a fantastic addition to any RVer’s stabilization arsenal, especially if you have slide-outs. They are not meant to replace your main RV stabilizer jacks for the entire rig, but rather to specifically support the slide-outs, which often contribute significantly to interior movement. The triangular screw design is a clever detail that really locks things into place, and the U-shaped tops fit perfectly. Remember to use a 2×4 with them to protect your slide-out frame.


Helpful Comparison Insights

When you’re looking for the best RV stabilizer jacks for stability and safety, it’s crucial to understand the subtle differences between types. We’ve seen a mix of scissor jacks and screw-type jacks, each with its own advantages.

For those with heavier RVs or motorhomes, the Kohree 7500lbs RV Stabilizer Leveling Scissor Jacks stand out. Their heavy-duty steel construction and high capacity are unmatched for sheer brute strength and robust leveling capability. They offer dual operation (manual or drill), which is a huge convenience for larger rigs that take more effort to stabilize. If your primary concern is rock-solid support and you don’t mind the extra weight, these are an excellent choice.

On the other hand, if portability and lighter weight are paramount, the aluminum screw-type jacks like the RV Stabilizer Jacks Set of 4 – Aluminum Trailer Jack, SHALL RV Stabilizer Jacks, and RVGUARD RV Stack Jacks are fantastic. All three offer an impressive 7500 lbs (or 6000 lbs for RVGUARD) per jack, proving that aluminum can still provide serious stability. The SHALL RV Stabilizer Jacks impressed me with their extra rubber pads and nuts, showing a commitment to long-term use and chassis protection. The RVGUARD RV Stack Jacks shine with their included storage bag, making them incredibly easy to transport and store, though with a slightly lower capacity. The RV Stabilizer Jacks Set of 4 – Aluminum Trailer Jack offers a well-rounded package of high capacity, adjustability, and protective pads without any unnecessary frills. These aluminum options are generally easier to set up and adjust using their “T” handles, making them user-friendly for most campers. It’s important to remember that all these aluminum options are designed purely for stabilization, not for lifting the RV, a crucial safety distinction.

Finally, for RVs with slide-outs, the LUSHIH RV Slide Out Support Trailer Stabilizer Jacks offer a specialized solution. While they aren’t meant to stabilize your entire RV, their heavy-duty steel and unique triangular screw design are incredibly effective at preventing sag and movement in slide-outs. If you’ve ever felt your RV sway when someone walks on a slide-out, these are a game-changer. They complement, rather than replace, your main RV stabilizer jacks.

Consider your RV’s weight, your desire for portability, and whether you need specialized support for slide-outs when making your decision. Each of these products offers a compelling solution for enhanced RV stability and safety.


Final Verdict

Choosing the best RV stabilizer jacks for stability and safety really boils down to your specific needs and type of RV. For those with hefty motorhomes or large travel trailers where maximum stability and heavy-duty performance are non-negotiable, I’d lean towards the Kohree 7500lbs RV Stabilizer Leveling Scissor Jacks. Their steel construction and high capacity instill confidence, especially when dealing with significant weight.

If you’re an RVer who values lightweight portability combined with robust stabilization for your travel trailer or smaller RV, the aluminum options are your best bet. Among them, the SHALL RV Stabilizer Jacks get a strong nod for their extra accessories and durable die-cast aluminum, while the RV Stabilizer Jacks Set of 4 – Aluminum Trailer Jack offers a fantastic all-around package.

Comprehensive FAQ Section

Q1: Why are RV stabilizer jacks important for stability and safety?
A1: RV stabilizer jacks are crucial because they prevent your RV from rocking, swaying, and bouncing, especially when people move around inside or when it’s windy. This not only makes your camping experience more comfortable but also enhances safety by reducing the risk of items falling or the RV shifting unexpectedly, providing a solid foundation for your temporary home.

Q2: What’s the difference between leveling jacks and stabilizer jacks?
A2: This is a common point of confusion! Leveling jacks (or systems) are designed to lift and level your RV, correcting for uneven terrain. They support the full weight of the RV and ensure it’s perfectly horizontal. Stabilizer jacks, on the other hand, are primarily designed to prevent movement and sway after the RV is leveled. They add rigidity and reduce bounce but are not meant to lift the RV or bear its full weight. Using stabilizer jacks to level your RV can damage them or your rig.

Q3: How many RV stabilizer jacks do I need for my RV?
A3: Most RVs benefit from having at least four stabilizer jacks – one at each corner of the frame. This provides the most comprehensive support and effectively minimizes movement. Some larger RVs or those with multiple slide-outs might benefit from additional jacks, like specialized slide-out support jacks, to further enhance stability.

Q4: Can I use a power drill with my RV stabilizer jacks?
A4: Many scissor-style stabilizer jacks, like the Kohree model we reviewed, are designed to be operated with a power drill (using a specific socket bit) in addition to a manual crank. This can significantly speed up the setup and teardown process. However, always check the manufacturer’s instructions for your specific jacks to ensure they are compatible with power tools and to avoid overtightening.

Q5: Are aluminum RV stabilizer jacks as strong as steel ones?
A5: Modern aluminum stabilizer jacks are surprisingly strong and can handle significant weight capacities (e.g., 6000-7500 lbs per jack, as seen in our reviews). While steel typically has a higher ultimate tensile strength, aluminum’s excellent strength-to-weight ratio makes it a great choice for RV stabilizers. Aluminum jacks are also lighter and more resistant to rust and corrosion, which are big advantages for RVers. For pure stabilization, quality aluminum jacks are generally more than adequate.

Q6: What are RV slide-out support jacks, and do I need them?
A6: RV slide-out support jacks, like the LUSHIH model, are specialized stabilizers designed to support your RV’s slide-outs. Slide-outs, despite adding space, can sometimes sag or contribute to the RV’s overall sway, especially when people walk on them. Slide-out support jacks prevent this movement, making your extended living space feel much more solid and reducing stress on the slide-out mechanisms. You might need them if you experience noticeable bounce or instability in your slide-outs.

Q7: How do I properly set up my RV stabilizer jacks for optimal stability?
A7: First, ensure your RV is level using your leveling system or blocks. Once level, extend your RV stabilizer jacks down until they make firm contact with the ground or solid blocks (wood or concrete pads are recommended to prevent sinking). Don’t overtighten; you just want them snug. The goal is to apply upward pressure to the RV frame, making it rigid and resistant to movement, not to lift the RV further. Start with the corners and then add any mid-point or slide-out jacks.

Q8: Can RV stabilizer jacks be used on uneven ground?
A8: Yes, most RV stabilizer jacks are designed with adjustable heights to accommodate uneven ground. However, their primary role is stabilization, not leveling. You should always level your RV first, using your leveling system or appropriate leveling blocks, before deploying your stabilizer jacks. Once the RV is level, the stabilizers can then be extended to firmly contact the uneven ground and prevent movement. Using sturdy pads or blocks under the jacks is always recommended on uneven or soft surfaces.
