Ever felt like you’re living on a boat while parked at a campsite? That unsettling “RV wiggle” can turn a peaceful night into a dizzying ordeal. Stabilizer jacks are the unsung heroes of the road, grounding your rig to eliminate the swaying and bouncing caused by foot traffic or wind. Whether you’re after the permanent brawn of scissor jacks or the nimble portability of aluminum stacks, our guide breaks down the elite gear designed to keep your sanctuary steady.
1. Kohree 6500lbs Heavy Duty RV Stabilizer Jacks
- Capacity: 6,500 lbs per jack
- Lift Height: 4″ to 24″ range
- Material: Electrophoresis-coated heavy duty steel
- Included: Crank handle and drill socket
The Kohree 6500lbs stabilizers are a masterclass in combining ruggedness with fluid movement. Forged from high-tensile steel and treated with a specialized electrophoresis coating, these jacks laugh in the face of rust and road salt.

How to Purchase the Right Stabilizer Jacks for Your RV
Buying stabilizer jacks isn’t just about picking the highest weight rating or the lowest price. It’s about understanding the physics of your specific trailer and how you intend to camp. This comprehensive guide will walk you through every nuance of the purchasing process, ensuring that your investment results in a rock-solid, comfortable living space.
Step 1: Understand the Goal (Stabilization vs. Leveling)
Crucial Warning: Never use a stabilizer jack to lift your RV for a tire change or to level a significantly tilted trailer.
The most common mistake is confusing a stabilizer with a leveling jack. High-end motorhomes have hydraulic leveling systems designed to lift the vehicle. However, the scissor and stack jacks listed above are purely for stabilization. They are meant to be deployed *after* you have used leveling blocks to get the rig flat. Their job is to create tension between the frame and the ground to stop swaying. Over-tightening them in an attempt to “lift” the trailer can result in bent jack arms or, worse, a warped trailer frame.
Step 2: Scissor Jacks vs. Stack Jacks – Which is Right for You?
Choosing between a permanent mount and a portable stand depends on your trailer type and your patience for setup.
- Scissor Jacks: These are bolted or welded to the chassis. They are incredibly convenient because they are always “there.” They offer higher weight capacities (up to 9,000 lbs) and a longer reach (up to 24 inches). Choose these if you have a mid-to-large travel trailer or fifth wheel.
- Stack Jacks (Jack Stands): These are individual, portable units. They are usually made of aluminum, making them rust-proof and lightweight. They are perfect for pop-up campers or as “supplemental” support in the middle of a long trailer to prevent the floor from flexing in the kitchen area.
Step 3: Measuring Your Ground Clearance
Before you hit “buy,” you must know your frame-to-ground distance. Park your RV on a level surface and measure the distance from the bottom of the frame to the ground.
- Standard Clearance: Most trailers sit between 15 and 20 inches from the ground. A 24-inch scissor jack is the perfect choice here, as it gives you a few inches of “wiggle room” for uneven terrain.
- Low Clearance: Pop-ups and small teardrop trailers often sit lower. Stack jacks with an 11-17 inch range are usually sufficient and easier to fit under the rig.
- High Clearance/Off-Road: If you have an off-road package, your frame might be 22+ inches off the ground. In this case, you must either buy “high-lift” jacks or use specialized jack blocks to bridge the gap. Using a jack at its absolute maximum extension reduces its stability.
Step 4: Decoding Weight Capacity
You’ll see ratings like 5,000 lbs, 6,500 lbs, and even 9,000 lbs. Since these jacks don’t support the full weight of the RV, why do you need such high numbers?
The answer lies in rigidity. A 9,000 lb jack uses thicker steel and a beefier screw mechanism than a 5,000 lb jack. This means less “flex” in the metal itself. If you want the most stable feel inside your trailer, aim for a capacity that exceeds your trailer’s total weight, even though the jack isn’t lifting it all.
Step 5: Material Science and Coatings
Your jacks live in a “death zone” of mud, salt, and water.
Steel Jacks: These must have a high-quality finish. Look for Electrophoresis or Powder Coating. Plain painted steel will chip and rust within one season, causing the screw to seize.
Aluminum Jacks: These are the champions of coastal camping. Aluminum doesn’t rust, making these stands ideal if you frequently camp near the ocean where salt air is a constant threat.
Step 6: Installation Readiness
If you choose scissor jacks, determine how you will attach them.
Bolt-On: Most DIYers prefer this. Ensure your trailer frame has a flat section where you can drill holes. Check if the kit includes bolts; many (like the ROCKMAN) do not.
Weld-On: This is the most secure method but requires a professional welder. It’s the best choice for heavy-duty applications.
Universal Fit: Check the mounting plate dimensions. Most are 3″ x 6″ or 4″ x 9″. Ensure your frame cross-members can accommodate these footprints.
Step 7: Ease of Use and Accessories
Don’t overlook the small features that make setup easier:
Power Drill Compatibility: Manually cranking four jacks is a workout you don’t want after a long drive. Ensure the jack has a 3/4″ hex nut and that a drill socket is included.
Magnetic Sockets: Brands like LIBRA include magnetic sockets. This prevents the bit from falling off and rolling under the trailer in the dark.
Footpads: Wide “bow-tie” feet are essential for stability on sand or grass. If the jack has small feet, you’ll need to buy separate plastic jack pads.
Step 8: Maintenance for Longevity
To ensure your purchase lasts, you need a maintenance plan. At the start of each season:
- Clean: Use a brush to remove grit from the screw threads.
- Lubricate: Use a dry silicone lubricant. Never use grease or WD-40, as these attract road dirt and create a grinding paste that destroys the threads.
- Inspect: Tighten mounting bolts and check for any signs of metal fatigue or cracking.
Conclusion: Investing in a Solid Base
A stable RV isn’t just about comfort—it’s about preserving your vehicle. Excessive rocking puts strain on door frames, cabinets, and plumbing connections. By choosing a high-capacity, well-coated stabilizer system tailored to your rig’s height, you’re ensuring your home on wheels remains a peaceful sanctuary. Whether you opt for the permanent strength of Camco or the rust-proof portability of SHALL, the right jacks are the foundation of every great camping memory.
