Kohree RV Slide Out Support Jacks 4PCS — 20,000 lb Capacity, 20"–49" Adjustable Stabilizers

Kohree RV Slide Out Support Jacks 4PCS are a set of four adjustable stabilizer jacks designed to dramatically reduce slide-out movement for large fifth wheels and Class A motorhomes.

If you own a large camper with one or more long slide-outs, movement from wind, passing traffic, or uneven ground can stress the slide mechanism and create annoying swaying. The Kohree 4PCS slide-out supports give heavy-duty reinforcement with a total rated capacity of 20,000 lbs, an adjustable height range of 20" to 49", and dual operation options so you can set and hold slide-outs quickly and securely.

How do these supports reduce slide-out shake?

These jacks sit under the slide-out and transfer lateral and vertical forces down to the ground, sharply cutting the amount of movement felt inside the camper. Using four jacks distributes load across multiple contact points for longer slide-outs or multi-room extensions.

• Total rated capacity: 20,000 lbs for the full 4-piece set
• Four-point support lowers sway and vibration compared with 2-jack arrangements
• Solid steel construction resists bending in wind and snow conditions

What tools and methods are used to adjust the jacks?

Kohree jacks provide two operating options so you can choose speed or precision. Use a power drill with the supplied socket for fast deployment, or switch to the included hand-crank handle for manual control when fine adjustments are needed.

• Fast adjustment: power drill + socket (saves time vs. hand crank)
• Manual option: traditional hand-crank handle for precise leveling
• Socket-compatible head designed for common drills and impact drivers

Will these supports fit my RV and different ground surfaces?

The adjustable 20"–49" height range covers most common distances from the slide-out bottom to ground on trailers and motorhomes. The wide range helps compensate for uneven terrain and gives a stable base for long slide-outs or multi-room extensions.

• Adjustable heights: 20 inches minimum to 49 inches maximum
• Works on gravel, packed dirt, campsite pads, and paved surfaces
• Use leveling blocks or pads if needed for very soft ground

Are these jacks intended to support the RV’s entire weight?

No — these stabilizers are intended to stabilize and reduce slide-out motion, not to bear the full weight of the vehicle. They protect slide mechanisms and interior stability but should not replace chassis or leveling jacks for lifting or long-term vehicle support.

• Designed to prevent slide-out shaking, not to lift the motorhome/trailer
• Complement, don’t replace, existing RV leveling or landing gear
• Recommended for longer or multiple slide-outs to improve longevity

Who this is for: Kohree RV Slide Out Support Jacks 4PCS are a practical choice for full-time RVers, families with large fifth wheels, and owners of Class A motorhomes who want to protect slide-out mechanisms and enjoy a steadier interior. They are especially useful when you have slide-outs longer than 12 feet, multiple adjoining rooms, or frequent camping in windy or uneven sites. If you need rapid setup and flexible adjustment tools, or you want to lower vibration without modifying the RV’s structure, this four-piece set is engineered for that purpose.
