Product Roundup: Best RV Slide-Out Supports For 2025
1. Ultra Fab Heavy Duty RV Slide-Out Supports

Best for: Heavy-duty stabilization
When it comes to keeping your RV slide-outs stable and secure, the Ultra Fab Heavy Duty RV Slide-Out Supports are an absolute standout.
These supports are designed with heavy-duty steel construction and a zinc coating for rust resistance, making them tough enough to handle the demands of any camping trip. I’ve used these myself and can confidently say they’re one of the most reliable solutions for reducing sway and protecting your slide-outs.
One of the standout features of these supports is their impressive adjustability. They’re available in three height ranges – 16" to 28", 21" to 37", and 26" to 47" – which makes them suitable for a wide range of RV configurations.
The quick-release nylon adjustment buttons are a game-changer, allowing you to set the height easily without fumbling with tools. This is especially handy when setting up on uneven ground, where precise adjustments can make all the difference.
I’ve noticed a significant reduction in rocking and swaying when these supports are in place, especially when multiple people are moving around inside the RV. They also help protect the slide-out extension tubes, preventing sagging and extending the life of your RV’s mechanisms.
The 5" circular base ensures a stable footing, even on softer surfaces like grass or dirt.
That said, it’s important to use these supports correctly. If not properly aligned, they could cause misalignment with the slide-out mechanism, leading to unnecessary wear. Some RVers debate their necessity, but in my experience, the added stability makes a noticeable difference in comfort and longevity.
For anyone looking to enhance their RV’s stability, the Ultra Fab Heavy Duty RV Slide-Out Supports are a must-have – they’re durable, easy to use, and an essential part of my camping setup.

2. Rieco Titan Stable Stix For Campers

Best for: Truck campers
If you own a truck camper, the Rieco Titan Stable Stix are an essential addition to your setup. These innovative supports are designed to minimize swaying and improve stability, particularly in challenging conditions like uneven terrain or strong winds.
I’ve recommended these to countless fellow RVers and truck camper enthusiasts because they deliver a noticeable improvement in comfort and safety.
One of the best features of the Stable Stix is its simplicity and effectiveness. The telescoping steel tubes are robust yet lightweight, and they extend from 57" to 87" in 3" increments, offering plenty of adjustability to fit most campers.
What I particularly appreciate is the included 10' ratchet strap, which ensures a snug, secure fit under the front cabover area. This design not only distributes weight evenly but also prevents tipping, which can be a concern for truck campers with heavy overhangs.
The setup is straightforward and takes just a couple of minutes.
The powder-coated steel construction is tough enough to withstand the rigors of the road while resisting rust and corrosion. Another advantage is how compact the Stable Stix are when not in use – they’re easy to store, saving valuable space in your camper.
However, I do recommend regularly checking the ratchet strap during use, as some users report that it can loosen over time. And while the Stable Stix are fantastic for stabilization, they work best when the camper is lowered as much as possible to maximize their effectiveness.
For truck camper owners, the Rieco Titan Stable Stix are a game-changer. They offer excellent stability, reduce movement, and make your camper feel more like home – even in less-than-ideal conditions.
It’s a small investment for a big improvement in your camping experience.

3. Husky Towing 5th Wheel King Pin Stabilizer

Best for: Fifth-wheel trailers
If you’re a fifth-wheel owner, you’ve likely experienced the frustrating movement that can happen when parked, especially on uneven terrain.
The Husky Towing 5th Wheel King Pin Stabilizer is one of the best solutions I’ve found for eliminating that sway and giving your RV a rock-solid feel. It’s a heavy-duty piece of equipment that enhances stability and comfort while protecting your trailer’s landing gear.
What I love about this stabilizer is its sturdy steel construction, which can handle up to 5,000 lbs. The adjustable legs accommodate kingpin heights ranging from 34" to 56", making it compatible with most fifth-wheel trailers.
The powder-coated finish ensures long-term durability by resisting rust and wear, even in tough weather conditions. The locking hitch cup is another standout feature. It allows for secure attachment to the kingpin and prevents theft, adding a layer of security to your setup.
The stabilizer’s chain system links the legs for added stability, and while it requires a bit of fine-tuning during setup, it pays off with a noticeable reduction in motion. I’ve personally seen how this can eliminate the rocking caused by people moving around inside the trailer or the washer/dryer running.
However, storage can be a challenge, as the stabilizer is a bit bulky. It’s also worth noting that setup might take a little extra effort to ensure the chain system and legs are properly aligned. But once in place, it’s a game-changer for long-term stays or when you want to feel more secure in your trailer.
The Husky Towing 5th Wheel King Pin Stabilizer is an investment in comfort and peace of mind: it’s perfect for anyone looking to improve stability and protect their fifth-wheel trailer from unnecessary stress and strain.

4. Lippert Drive Shaft Collar Support

Best for: Smooth slide-out operation
The Lippert Drive Shaft Collar Support may be a small component, but its role in your RV’s slide-out system is absolutely critical.
As someone who’s worked extensively with Lippert Above Floor Slide-Out systems, I can tell you that this support is essential for maintaining smooth, reliable slide-out functionality.
What makes this collar support stand out is its ability to prevent drive shaft sagging. Sagging can cause misalignment and jerky movements, putting undue stress on the slide-out motor and gears. By stabilizing the drive shaft, the collar support reduces wear and tear and ensures that your slide-out extends and retracts smoothly every time.
The construction is robust, with materials like steel or stainless steel that are built to last.
It’s designed specifically for Lippert’s Above Floor Slide-Out systems, so compatibility is seamless. Installation is straightforward, provided you follow Lippert’s guidelines carefully. A clean shaft and evenly tightened set screws are key to ensuring the collar does its job effectively.
One of the major advantages is how this component contributes to the longevity of your slide-out system. Proper alignment prevents costly repairs down the line, and I’ve seen firsthand how a well-maintained slide-out system can enhance the overall RV experience.
That said, this product is highly specific to Lippert systems, so it won’t be suitable for other types of slide-outs. Also, while it’s easy to install, incorrect placement or insufficient tightening can lead to slippage or noise during operation.
If you own a Lippert Above Floor Slide-Out system, the Drive Shaft Collar Support is an indispensable part of keeping your RV running smoothly.
It’s a small but mighty investment in the long-term health of your slide-out.

5. Carefree RV Roller Tube Support For SOKIII/Summit Slide Out Awnings

Best for: Awnings
If your RV has a Carefree SOKIII or Summit slide-out awning, the Carefree RV Roller Tube Support is a must-have accessory.
I’ve seen how vulnerable awnings can be to sagging and pooling, especially during heavy rain or wind. This simple but effective support prevents those issues and significantly improves the longevity of your awning.
The primary function of this roller tube support is to prevent sagging in the middle of the awning. By maintaining tension and keeping the roller tube properly aligned, it ensures smooth operation and reduces strain on the awning components.
One of my favorite features is how it helps prevent water pooling, which can lead to fabric damage, mold growth, or leaks. With the support in place, your awning stays taut and well-protected, even in challenging conditions.
Made from lightweight materials, this support is easy to install and comes with screws for added convenience. At just 1 lb., it’s compact and won’t take up much storage space when not in use.
Its design is specific to Carefree’s SOKIII and Summit awnings, so compatibility is guaranteed for those models.
That said, there are a few considerations. The support won’t address issues caused by debris or improper tensioning, so regular maintenance of your awning is still essential. Additionally, while the support is great for preventing sagging, it doesn’t resolve potential wind damage if the awning isn’t properly secured.
For Carefree awning owners, this roller tube support is an excellent investment in both performance and peace of mind.
This is just one of those products that pays for itself by extending the life of your awning and making your RVing experience more enjoyable.

6. Lippert Electric Stabilizer RV Jack Support Arm

Best: Electric RV stabilizers
The Lippert Electric Stabilizer RV Jack Support Arm is an essential upgrade for anyone looking to improve the stability of their RV.
As a direct replacement for Lippert’s electric stabilizer jack systems, this support arm is built to handle the demands of RV life while ensuring your setup remains secure and steady.
What I appreciate most about this support arm is its heavy-gauge steel construction. It’s designed for durability, with a powder-coated yellow finish that resists corrosion, even in tough outdoor conditions. Its compatibility with all Lippert power stabilizer jacks makes it a versatile choice, and at just 1.5 lbs, it’s lightweight yet strong enough to deliver the stability you need.
Installing this support arm is relatively simple, though it’s worth noting that the necessary mounting hardware isn’t included. Standard bolts and washers can be purchased separately, and with the right tools, you can easily replace a damaged arm in no time.
Once installed, the difference in stability is immediately noticeable. Swaying and rocking are significantly reduced, even when people are moving inside the RV.
One aspect to keep in mind is the importance of proper installation. If the arm isn’t secured correctly, it could bend under pressure, compromising the stabilizer’s performance. Following the manufacturer’s instructions carefully will help you avoid any issues and ensure long-lasting support.
For RVers using Lippert’s electric stabilizer jacks, this support arm is a cost-effective way to maintain the stability and comfort of your setup.
It’s a reliable, durable, and practical solution that ensures your RV remains steady no matter where your travels take you.

Buying Tips For Getting the Best RV Slide-Out Supports

Stabilizing your RV slide-outs is crucial for comfort, safety, and the longevity of your equipment. Choosing the right slide-out supports can make a huge difference in reducing movement, preventing damage, and enhancing your camping experience.
With so many options available, it’s important to consider key factors before making your purchase. Here are my top tips to help you find the best slide-out support for your needs.
Choose the Right Size and Adjustability
Slide-out supports come in various height ranges, so selecting the correct size for your RV is essential. Measure the clearance beneath your slide-outs and check the product’s height adjustability to ensure a proper fit. Supports with quick-release mechanisms or fine adjustment features make it easier to achieve the perfect setup, especially on uneven terrain.
Remember to: Opt for a product with enough range to accommodate slight variations in your RV’s leveling.
Prioritize More Durable Materials
Since slide-out supports bear significant weight, durability is key. Look for supports made from heavy-duty steel or aluminum, which offer the strength needed to stabilize your slide-outs while resisting rust and corrosion. Powder-coated finishes add an extra layer of protection, ensuring that the supports remain functional even after prolonged exposure to the elements.
Remember to: Look for the best materials – high-quality materials mean fewer replacements and long-term reliability.
Think About Weight Capacity and Stability
The weight capacity of slide-out supports is a critical factor. Ensure the supports can handle the weight of your slide-outs, especially if they contain heavy furniture or appliances. Exceeding the weight limit can compromise stability and damage the supports.
Remember to: Look for supports with high weight ratings and stable bases to prevent tipping or sinking on uneven ground.
Factor in Setup and Convenience
Ease of setup can make or break your experience with slide-out supports. Models with tool-free adjustment mechanisms or quick-release buttons save time and effort during installation. Supports with wide bases provide greater stability, particularly on uneven or soft surfaces.
Remember: For truck campers, consider options like Rieco Titan Stable Stix, which include ratchet straps for added security.
