The best support for an RV slide-out depends on its height, the amount of support you need, and whether you prefer drill-assisted adjustment. Kohree’s standard pair suits buyers wanting a broad height range, LUSHIH’s jacks fit lower setups, and the four-jack Kohree set is designed for larger RVs. RVSHARK offers a higher stated capacity per jack, while Kohree’s flat-top pair avoids the need for a separate top block.
| Product | Best For | Listed Height Range |
|---|---|---|
| Kohree Set of 2 | General-purpose height range | 20–49 inches |
| LUSHIH 2 Pack | Lower slide-outs | 15–26 inches |
| Garvee Set of 4 | Four-point support setup | 21.1–49 inches |
| Kohree Flat-Top Set of 2 | Support without a separate wood block | 20–49 inches |
| RVSHARK Set of 2 | Higher stated capacity per jack | 20–49 inches |
Kohree RV Slide Out Supports, Set of 2
This pair is best for RV owners who need a wide adjustment range and want the option of drill-assisted setup. Each support is listed with a 5,000-pound capacity, and the height adjusts from 20 to 49 inches. The package includes two jacks, a crank handle, and a drill socket.
Choose this set if your measured slide-out support height falls within its range and you value having both manual and drill operation. The limitation is that the set contains only two supports; buyers looking for a four-jack setup should compare a four-piece option.
LUSHIH RV Slide Out Support Jacks
LUSHIH is best for buyers whose support point is lower than the ranges offered by many taller jacks. The stated travel range is 15 to 26 inches, with an 11-inch working range and a maximum lift capacity of 5,000 pounds per jack. The steel jacks have a zinc powder-coated finish and U-shaped tops.
The product information recommends placing a 2-by-4 along the tops to help avoid damage to the trailer. That means this option is less convenient for shoppers seeking a flat support surface without extra material. Confirm the required height before choosing it, since its maximum adjustment is lower than the other selections here.
Garvee RV Slide Out Support Jacks, Set of 4
This Garvee set is best for buyers who want four adjustable jacks rather than a two-piece set. Each jack is listed with a 5,000-pound capacity, and the height range is approximately 21.1 to 49 inches. A hand crank and magnetic drill socket are included for manual or drill-assisted adjustment.
Choose it if the height range works for your RV and you want four supports available for setup. The product description also refers to a two-jack set when discussing sway reduction, so confirm the package contents and follow the instructions for placement. Do not treat the combined capacity as permission to exceed the RV or support manufacturer’s limits.
Kohree Supports With Flat Top Blocks
This Kohree pair is best for RV owners who want a flat top support block built into the jack. The listed height range is 20 to 49 inches, and the supports can be adjusted with a power drill or hand crank. The product description says the flat top is intended to provide support without an extra wood block.
Compared with the standard Kohree pair, the distinguishing feature is the flat top design. The supplied information does not state a load capacity, so buyers should verify the capacity and intended use with the manufacturer before selecting this model for a particular slide-out.
RVSHARK 6,000-Pound Slide-Out Supports
RVSHARK is best for shoppers comparing a higher stated capacity per jack. The product lists each jack at 6,000 pounds and gives a 20-to-49-inch adjustment range with a three-level adjustable base. It supports drill-assisted and manual operation and is described as using high-strength alloy steel and reinforced galvanized tubes.
Choose this pair if its height and capacity specifications suit your setup. The listing specifies a 20–24V cordless drill for powered adjustment; check your drill’s voltage before relying on that feature. The stated capacity is a product specification, not a substitute for following the RV manufacturer’s support guidance.
Buying Guide: How to Choose RV Slide-Out Supports
What height range do you need?
Measure the distance from the intended support surface to the slide-out’s specified support point. Compare that measurement with the jack’s listed range. LUSHIH covers 15–26 inches, while the other featured options reach approximately 49 inches. A jack that cannot reach the required height is not a suitable match.
Should you choose two jacks or four?
A two-jack set may suit buyers seeking a pair of supports. Four-jack sets provide more individual supports, but the correct number and placement depend on the RV and its manufacturer’s directions. A set’s total or per-jack capacity does not establish how it should be positioned.
Do you want a flat top or a drill socket?
A flat top can reduce the need for a separate block, as described for the Kohree flat-top model. Other products include a drill socket or support a drill for faster adjustment. Manual crank operation is also listed on several models. Check included accessories and the product’s instructions before use.
How should capacity affect the decision?
Compare the listed capacity per jack, not just a set’s headline number. The featured products list 5,000 pounds per jack for several models and 6,000 pounds per jack for RVSHARK. Do not assume that a set’s stated capacity means the slide-out itself should carry that load. Follow the RV and jack manufacturers’ limits.
Frequently Asked Questions
Are RV slide-out supports meant to lift the RV?
These products are described as slide-out supports or stabilizer jacks. Do not use them to lift an RV unless the product and RV manufacturers explicitly permit that use.
Can I adjust slide-out supports with a power drill?
Several featured models support drill-assisted adjustment. Check the product details for the required socket or drill specifications, and retain the manual crank option where provided.
Do all RV slide-out supports need a wood block?
No. LUSHIH recommends a 2-by-4 along its U-shaped tops, while Kohree’s flat-top model says it does not require an extra block. Follow the specific product instructions.
How do I choose between a 5,000- and 6,000-pound rating?
Compare the stated capacity per jack with the support requirements specified for your RV. A higher rating alone does not confirm that a jack fits your slide-out or support location.
