Choosing the right support for your slide-out comes down to matching your RV’s ground clearance and how much vibration you want to cut. While all these units share similar weight capacities, the main differences lie in their height ranges, the type of top plate they use, and how easily they adjust for your specific setup.
Best overall: Garvee RV Slide Out provides a versatile height range and includes a magnetic hex socket for fast drill adjustments, making it a reliable choice for most standard campers and travel trailers. Best for first-time buyers: Camco Eaz-Lift Support offers a trusted design with a simple two-stage adjustment system that helps beginners manage slide-out sagging without needing complex tools or extra installation parts. Best for high-clearance rigs: Quick Lift Support features an extended 25-53 inch reach, which is ideal for RVs that sit higher off the ground and require extra support for their slide-out mechanisms.
If you’re new to this, focus on measuring your rig’s clearance before buying to ensure you get the right height range.

1. Garvee RV Slide Out Support Jacks (Set of 4)
Best for: Most standard travel trailers and campers.
The Garvee RV Slide Out stands out by offering a broad 21.1 to 49-inch height adjustment, which covers the majority of standard RV slide-out configurations. The inclusion of both a manual crank and a magnetic hex socket for a power drill means you can set them up quickly without extra trips to the hardware store. Because these are designed to stabilize rather than lift, they’re perfect for reducing the “bounce” you feel inside when walking on the slide-out floor.
These jacks use a 5.1-inch by 1.2-inch steel top plate, which provides a wide contact point to distribute pressure evenly. This design helps prevent localized stress on your slide-out rails, which is vital for long-term maintenance. If your RV has very low ground clearance, the 21.1-inch minimum height might be too tall for your specific setup.
Pros
- Wide 21.1-49 inch height range.
- Includes magnetic hex drill socket.
- Rugged steel construction for durability.
Cons
- Not suitable for very low-clearance rigs.
- Designed for stabilization, not for lifting.
2. Camco Eaz-Lift Adjustable RV Slide-Out Support
Best for: Owners who prefer a trusted, well-known brand.
Camco Eaz-Lift Support uses a two-part adjustment system that allows for both coarse and fine tuning of the height. The red lever on the base handles the big height jumps, while the threaded rod lets you lock it in exactly where you need it. This dual approach is very helpful if you frequently camp on uneven ground where a simple one-way jack might struggle to find the right tension.
This model is built to fit standard slide-out rails, making it quite compatible with older and newer trailer models alike. Because the tops are reversible, you can flip them to accommodate either rail-style slide-outs or flat-bottom designs. If you need something that can reach higher than the maximum extension, this model will fall short of your requirements.
Pros
- Reversible top for different rail types.
- Simple two-stage height adjustment.
- Fits standard rails.
Cons
- Maximum 49-inch height limit.
- Heavier at approximately 9 lbs each.
3. Kohree RV Slide Out Support Jacks
Best for: Campers who park on gravel or uneven ground.
The Kohree Tripod Support uses a unique three-point base design that provides extra stability on surfaces that aren’t perfectly flat. By creating a wider footprint than standard circular bases, it helps reduce the side-to-side sway that often happens in extended slide-out rooms. It also features an ergonomic handle that makes it easier to position the jack accurately, even when you’re working in tight spaces.
The flat top design is a nice touch, as it allows you to place the jack directly under the slide-out without needing extra wood blocks or spacers. While the 7,500-lb capacity is high, remember that this is for stabilization only, not for lifting your RV. If you have a very tight storage compartment, the tripod base might take up more room than a standard cylindrical jack.
Pros
- Stable 3-point tripod base design.
- High 7,500 lbs weight capacity.
- Ergonomic handle for easier positioning.
Cons
- Tripod base occupies more storage space.
- Not for lifting or leveling the RV.
4. VEVOR RV Slide Out Support Jacks
Best for: Buyers wanting a reliable pair.
The VEVOR Slide Out is built using 0.08-inch thick steel pipes and a spray-plastic finish that resists rust, which is great for those who camp in humid or muddy environments. It provides a solid 5,000-lb capacity per jack, ensuring that your slide-out stays firm while you move around inside. The adjustment process is straightforward, using a folding handle to bring the bracket up to meet your slide-out rail.
These are lightweight, making them easy to carry from your storage bay to the campsite. Because they focus on a simple design, they lack drill-compatible features. If you prefer to use a power drill for setup, you may find the manual handle adjustment takes a bit more time.
Pros
- Corrosion-resistant spray-plastic coating.
- Lightweight and easy to store.
- Sturdy 0.08-inch thick steel construction.
Cons
- No power drill compatibility.
- Manual handle adjustment only.
5. Quick Lift Support
Best for: RVs with high ground clearance.
The Quick Lift Support is designed for those who need more reach, with an adjustable range starting at 25 inches and going all the way to 53 inches. The internal gear box is built with metal components, which the manufacturer notes is an upgrade over plastic gear designs. This setup allows for smooth, fast adjustment using a power drill, which is a major time-saver when you’re setting up camp.
The addition of a rubber mat on the top U-shaped bracket is a smart feature, as it protects your RV’s finish from scratches and helps dampen vibrations. If your RV sits low to the ground, this model will be too tall even at its lowest setting. It’s specifically meant for high-clearance vehicles and may not fit smaller pop-up campers.
Pros
- Extended reach up to 53 inches.
- Rubber top mat protects RV finish.
- Metal gear box for drill use.
Cons
- Too tall for low-clearance slide-outs.
- Not for low-profile campers.
6. Compact Slide Out
Best for: Pop-up campers and low-profile travel trailers.
The Compact Slide Out is the best choice if your RV sits low to the ground, as it adjusts from 13.2 to 24 inches. This allows you to support slide-outs that would otherwise be too close to the ground for standard jacks to fit. Despite its smaller size, it still maintains a 5,000-lb capacity and features an aluminum gear box for durability.
The company offers lifetime after-sale service, which is a significant benefit for long-term reliability. You can use either a power drill or the included side-wind handle to adjust the height, providing flexibility depending on what tools you have on hand. Because of the low height range, these won’t work for large motorhomes or high-clearance fifth wheels.
Pros
- Excellent for low-clearance slide-outs.
- Includes lifetime after-sale service.
- Drill or manual adjustment options.
Cons
- Limited to low-profile vehicles.
- Not for high-clearance RVs.
7. Heavy Duty Stabilizer
Best for: Quick setup at the campsite.
The Heavy Duty Stabilizer is designed for speed, with a metal gear system that allows for a full height adjustment in about 10 seconds when using a power drill. The range of 15.6 to 34 inches is a good middle ground for many mid-sized travel trailers. Like other premium models, it features a rubber mat on top to keep your slide-out rails free of scratches and reduce metal-on-metal noise.
The full metal structure is intended to improve durability over models that rely on plastic internal parts. If you’re looking for a simple, fast-acting stabilizer, this is a strong contender. If you have a very tall or very low rig, you should double-check your measurements to ensure this range fits your needs.
Pros
- Fast 10-second adjustment with drill.
- Full metal internal gear construction.
- Protective rubber mat included.
Cons
- Not for extreme height requirements.
- Mid-range height may not fit all.
8. Rubber Mat Support
Best for: Damping vibration on small trailers.
The Rubber Mat Support by SKYFISH is another excellent option for low-clearance rigs, offering a 15-26 inch adjustment range. The anti-vibration rubber pad on the U-shaped top is specifically included to stop the metal-on-metal clanking that can happen in wind or when moving inside the RV. It’s a simple, effective design that keeps things steady without unnecessary complexity.
The 5-inch circular base helps distribute pressure on firm ground. Because these are designed for smaller trailers, they’re compact and easy to store in tight compartments. If you have a large RV with a high slide-out, you’ll need to look for a taller model, as this one won’t reach.
Pros
- Rubber pad reduces noise and vibration.
- Compact size for easy storage.
- Fits low-clearance slide-out rails.
Cons
- Not for high-clearance RVs.
- Limited height range.
9. Adjustable Drill Support
Best for: Maximum stability with drill-ready operation.
The Adjustable Drill Support stands out with a 7,000-lb capacity, which is higher than most other options on this list. This makes it a great choice if you want the most rigid support possible for your slide-out room. It’s fully compatible with power drills and comes with an adapter, meaning you can lock it into place in seconds.
The wide contact plate with a non-slip pad ensures a secure grip on your slide-out rail, minimizing the chance of slipping during use. It offers a 24-45 inch range, which works for a wide variety of campers and motorhomes. If you prefer a lighter, more basic jack, this heavy-duty model might feel like overkill.
Pros
- High 7,000-lb capacity per jack.
- Fast power drill compatibility.
- Wide non-slip contact plate.
Cons
- Heavier than standard stabilizer jacks.
- Maybe too robust for small trailers.
10. MAXSA RV Slide Out Support Jacks
Best for: Multi-slide RVs needing a 4-pack.
The MAXSA Stabilizer Jacks come as a set of 4, which is perfect if you have multiple slide-outs or want extra stability for a large rig. The dual-drive system allows for both manual cranking and power drill adjustment, ensuring you can set up quickly regardless of your power tool situation. With a 21.1 to 49-inch height, they’re versatile enough for most standard RVs.
The enlarged saddle plate is designed to prevent dents in the chassis, which helps preserve the long-term alignment of your slide-out mechanism. They’re coated with a corrosion-resistant finish to handle outdoor conditions over many seasons. Since this is a 4-pack, it’s a significant investment for those who only need to stabilize a single slide-out room.
Pros
- Comes as a convenient 4-pack.
- Dual-drive drill and manual setup.
- Large saddle plate prevents chassis dents.
Cons
- More pieces to store if not all needed.
- Heavier to transport than the smaller, more basic sets.
How to Choose in Sixty Seconds
Should I prioritize height range or weight capacity?
Always prioritize the height range first. Your slide-out support jack is useless if it can’t reach the bottom of your slide-out rail or if it’s too tall to fit underneath. Most RV slide-out support jacks are rated for 5,000 lbs, which is more than enough for the weight they’re intended to bear, as they aren’t meant to lift the RV. Measure the distance from the ground to the bottom of your slide-out rail before you order. A jack that’s too short will leave your slide-out unsupported, and one that’s too tall will force you to lift the slide-out, which can damage the mechanism. Safety standards for recreational vehicle slide-out systems generally emphasize proper support to prevent structural stress.
Is power drill compatibility worth the extra cost?
For many campers, yes. Setting up a campsite involves many steps, and manually cranking four jacks takes significant time and energy. Power drill compatibility allows you to raise or lower your jacks in seconds, which simplifies your setup and breakdown process. If you already carry a cordless drill for your RV stabilizer jacks or other tasks, a drill-compatible jack will integrate perfectly into your existing routine. However, if you prefer a simpler setup with fewer tools to carry, a manual crank model is perfectly capable of doing the job. Just ensure the model you choose includes the necessary hex socket or adapter, as some basic manual models don’t come with these parts.
What should I look for in the top contact plate?
The top contact plate is the part that touches your RV, so it needs to be secure and protective. Look for a U-shaped top if your slide-out has rails, as this keeps the jack centered. Models with rubber pads or non-slip surfaces are superior because they prevent the jack from sliding and protect the paint or finish on your slide-out rail from scratches. A flat top is useful for slide-outs without rails, but ensure it’s wide enough to provide a stable base. Avoid any jack that lacks a protective surface, as metal-on-metal contact can lead to noise and long-term surface damage to your trailer.

Frequently Asked Questions
Can I use these jacks to level my RV?
No, these jacks are designed only for stabilizing slide-out rooms, not for lifting or leveling the RV. Using them to lift your vehicle can cause serious damage to your slide-out mechanism. Always level your RV with primary jacks before placing these supports underneath to reduce sway.
What maintenance do these jacks require?
These jacks require minimal maintenance to ensure long-term performance. Keep the threaded rods clean of debris and apply a dry lubricant to maintain smooth adjustments. Periodically inspect any rubber pads for wear and check the metal gear box for signs of binding to keep the system operating correctly.
What happens if I choose the wrong height for my slide-out?
Always measure the distance from the ground to the bottom of your slide-out rail to ensure a proper fit. A jack that is too tall risks damaging the internal mechanism, while one that is too short will not provide support. Choose a model with an adjustment range that accommodates your specific measurement.
Are these jacks enough to stop all movement?
These jacks significantly reduce vibration and bounce, though they cannot eliminate all movement in an extended slide-out. Because the RV rests on its suspension, some motion is natural. Placing the jacks on a solid, level surface like a concrete pad or sturdy block will maximize the stability of your living space.
Closing
Selecting the best RV slide out support jacks depends entirely on your rig’s specific ground clearance and your preference for setup speed. The Garvee RV Slide Out remains a top choice for its versatility and ease of use, while the Camco Eaz-Lift Support is excellent for those who want a trusted, proven design for their trailer. Before you make your final choice, measure the distance from the ground to your slide-out rail to ensure the height range matches your needs. Once you have your measurements, consider whether you want the convenience of a drill-compatible model or the simplicity of a manual crank. A quick check of your storage space will also help you decide between a compact pair or a more comprehensive set for all your slide-outs.
