Kohree RV Slide-Out Support Jacks 4PCS — Flat-Top Telescoping Stabilizers, 20–49" Height, 20,000 lb Capacity

Kohree RV Slide Out Support Jacks (4PCS) are heavy-duty, adjustable stabilizers with a flat top that reduce slide-out shake and provide uniform support for large fifth wheels and Class A motorhomes.

When you park a motorhome or fifth wheel with extended slide-outs, movement from wind, people walking inside, or uneven ground can cause shaking that stresses components and reduces comfort. Kohree's 4-piece slide out support kit is engineered to give broader, more even bracing than two-jack setups, using high-strength steel and a flat-top design so you don't need extra wood blocks. These jacks are tool-adjustable and built to fit a wide height range, making them a practical add-on for full-time RVers and owners of larger rigs.

How do these supports reduce slide-out movement?

The four-jack arrangement delivers balanced support along the slide-out length to minimize bounce and lateral sway. The flat-top pads make direct contact with the slide-out frame for stable pressure distribution without additional shims.

• Four-point support spreads load evenly across the slide-out.
• Flat top eliminates need for wood or temporary blocks.
• Heavy-gauge steel construction resists bending under repeated use.
• Patent-pending design engineered to reduce shake by significant amounts.

What weight and height limits should I expect from these jacks?

Each Kohree kit is designed to work together to support slide-outs for large RVs and fifth wheels up to a combined rated capacity of 20,000 pounds. The telescoping columns adjust to fit a wide vertical range so you can level and brace on uneven ground.

• Combined support capacity: engineered up to 20,000 lbs.
• Adjustable height range: 20" to 49" to match most slide-out positions.
• Fine control using a socket and power drill for quick extension or retraction.
• Not intended to bear total vehicle weight—used only to stabilize slide-outs.

How quickly can I set them up and adjust them at the campsite?

Setup is faster than hand-cranked jacks because the top fitting accepts a socket for power-drill operation. That speeds deployment and retraction, so you spend less time fiddling and more time enjoying the campsite.

• Use a standard socket and drill for rapid height changes.
• Simple alignment and placement under slide-out frame—no cutting or permanent modifications.
• Flat top allows immediate contact without stacking blocks.
• Durable finish protects the steel from weather exposure.

Will these jacks work with my RV model and slide-out type?

Kohree designed the 4PCS set to be broadly compatible with common slide-out frames on Class A motorhomes, fifth wheels, and larger travel trailers. The adjustable height and flat top make them suitable for most installations, but you should verify clearance and frame contact points before purchase.

• Fits a wide range of slide-out configurations with 20"–49" adjustment.
• Flat top suits steel framing and box-style slide-outs for solid contact.
• Check that the slide-out underside has a secure bearing point for each jack.
• Not a substitute for primary suspension or frame supports; used for stabilization only.

Who is this for: Kohree’s 4PCS RV Slide Out Support Jacks are intended for RV owners who need stronger, faster, and more reliable stabilization than a basic two-jack setup—especially owners of larger fifth wheels and Class A motorhomes, full-time RVers, and anyone who experiences noticeable slide-out movement from wind, rain, or interior activity. If you want a durable, flat-top support set that adjusts quickly with a drill and provides broad, even bracing across your slide-outs, this kit offers a practical, non-permanent solution to improve comfort and reduce structural stress while parked.
