No, you cannot, and should not, use stabilizer jacks to level a trailer. Stabilizer jacks are designed to minimize bouncing and swaying once the trailer is properly leveled and stabilized. Using them to lift and level a trailer puts undue stress on the frame, potentially causing significant and costly damage.
Understanding the Critical Difference: Stabilizing vs. Leveling
It’s crucial to understand the distinct functions of stabilizer jacks and leveling equipment when setting up a trailer. Confusing the two can lead to serious structural problems and compromise the overall safety of your setup.
What are Stabilizer Jacks?
Stabilizer jacks are primarily designed to provide stability and prevent excessive movement within the trailer once it’s already level. They typically consist of lightweight scissor jacks or drop-down legs that extend from the trailer’s frame to the ground. These jacks are not designed to bear the full weight of the trailer. Their purpose is to eliminate or minimize the rocking motion caused by occupants moving inside the trailer. Think of them as preventing the “bounce” – hence the name.
What is Leveling Equipment?
Leveling equipment, on the other hand, is specifically engineered to lift and adjust the trailer’s height to achieve a perfectly level position. This equipment includes:
- Leveling blocks or ramps: Placed under the tires to raise the low side of the trailer.
- Tongue jacks: Used to raise or lower the front of the trailer.
- Electric or hydraulic leveling systems: Found on some higher-end trailers, these systems use powerful jacks to automatically level the trailer.
Why Leveling with Stabilizer Jacks is a Bad Idea
The structural integrity of your trailer is at stake when you misuse stabilizer jacks. Here’s why using them for leveling is a dangerous practice:
- Frame Damage: Stabilizer jacks are not designed to support the entire weight of the trailer. Using them to lift the trailer can cause the frame to bend, twist, or even crack. This damage is often irreversible and can significantly reduce the trailer’s lifespan.
- Jack Failure: Overloading stabilizer jacks can lead to premature wear and tear, or even catastrophic failure. If a jack collapses while you’re inside the trailer, it could cause serious injury.
- Uneven Weight Distribution: Leveling with stabilizer jacks can create uneven weight distribution across the trailer’s frame. This can lead to handling problems while towing and accelerate wear on the tires and axles.
- Compromised Stability: Ironically, using stabilizer jacks to level can actually reduce the trailer’s overall stability. If the jacks are overextended or improperly positioned, they can create a tipping hazard.
The Correct Procedure for Leveling and Stabilizing
To ensure the safety and longevity of your trailer, follow these steps for proper leveling and stabilization:
- Choose a Level Campsite: Ideally, select a campsite that is as level as possible to minimize the amount of leveling required.
- Use Leveling Blocks/Ramps: Place leveling blocks or ramps under the tires on the low side of the trailer until it is level side-to-side. Use a bubble level to verify.
- Disconnect from Tow Vehicle: Once level side-to-side, disconnect the trailer from the tow vehicle.
- Use Tongue Jack: Adjust the height of the tongue jack to level the trailer front-to-back. Again, use a bubble level to verify.
- Chock the Wheels: Securely chock the wheels to prevent the trailer from rolling.
- Lower Stabilizer Jacks: Finally, lower the stabilizer jacks to provide additional support and minimize movement inside the trailer. Do not over-tighten them. Just enough to make contact with the ground.

Frequently Asked Questions (FAQs)
FAQ 1: What happens if I accidentally used my stabilizer jacks to level the trailer a few times?
Monitor your frame closely for any signs of bending, twisting, or cracking. Inspect the welds around the jack mounting points. If you see anything suspicious, consult with a qualified trailer repair shop. It’s also wise to avoid doing it again.
FAQ 2: Are there different types of stabilizer jacks? Which are the strongest?
Yes, there are scissor jacks, drop-down jacks, and even some heavy-duty options. However, even the “strongest” stabilizer jacks are not intended for leveling. Their strength is relative to stabilizing, not lifting.
FAQ 3: My friend says he’s been leveling with stabilizer jacks for years and has never had a problem. Is he just lucky?
Potentially. But it’s more likely that the damage is accruing slowly and may not be immediately apparent. Structural damage can manifest over time, eventually leading to a major failure. It’s like smoking, the consequences often arise far into the habit.
FAQ 4: Can I use wood blocks under the stabilizer jacks for added stability?
Yes, placing wood blocks or pads under the stabilizer jacks is a good practice. It provides a larger contact area, especially on soft ground, and helps prevent the jacks from sinking into the dirt.
FAQ 5: What is the best type of level to use when leveling my trailer?
A bubble level is perfectly adequate for most situations. You can use a traditional bubble level or an electronic level. Some people also use apps on their smartphones to measure the trailer’s level.
FAQ 6: My trailer has an automatic leveling system. Does that mean I don’t need stabilizer jacks?
Automatic leveling systems level the trailer using powerful hydraulic jacks. While these systems often provide excellent stability, some people still prefer to use stabilizer jacks for added support, especially on uneven terrain or for extended stays.
FAQ 7: How often should I inspect my stabilizer jacks?
Inspect your stabilizer jacks before each trip and after setting up at your campsite. Check for any signs of damage, such as bending, cracking, or rust. Lubricate the jacks regularly to ensure smooth operation.
FAQ 8: Can I use my stabilizer jacks to change a tire on my trailer?
Absolutely not. Stabilizer jacks are not designed to lift the trailer for tire changes. Use a proper bottle jack or a specialized trailer jack designed for lifting the axle.
FAQ 9: What should I do if my stabilizer jacks are seized or difficult to crank?
First, try lubricating the jacks with a penetrating oil or grease. If that doesn’t work, you may need to disassemble the jacks and clean them thoroughly. If the jacks are severely damaged, it’s best to replace them.
FAQ 10: Are there any alternatives to stabilizer jacks for reducing movement inside the trailer?
Yes. X-chocks placed between the tires can significantly reduce fore and aft movement. Also, consider using jack pads beneath the tongue jack to prevent it from sinking.
FAQ 11: What are the weight capacity ratings of stabilizer jacks and how important are they?
The weight capacity rating of stabilizer jacks indicates the maximum load each jack is designed to support for stabilizing purposes only. Exceeding this rating can damage the jacks and compromise their effectiveness. Pay attention to the combined weight rating of all your jacks. While not for lifting the total weight of the trailer, the combined rating of all jacks should be appropriate for the general weight distribution of your rig.
FAQ 12: If I have a small pop-up trailer, does this rule still apply?
Yes, this rule applies to all trailers, regardless of size. Even with a lightweight pop-up trailer, stabilizer jacks are only for stabilizing, not leveling. Leveling blocks or ramps are still necessary.
Conclusion
Using stabilizer jacks to level your trailer is a dangerous practice that can lead to serious frame damage and compromise your safety. Always use proper leveling equipment to achieve a level position before deploying your stabilizer jacks. By following these guidelines, you can protect your investment and enjoy years of safe and comfortable camping.
