BEBOBLY RV Stack Jacks 4-Pack Screw Stabilizer Stands, 11"–17" Adjustable, 6000 lb Capacity Each

BEBOBLY RV Stack Jacks 4 Pack are compact screw-style stabilizer stands that steady and level travel trailers and campers, adjustable from 11" to 17" and rated to support up to 6,000 lb per jack.

If your RV rocks, tilts, or slides when parked, these lightweight, corrosion-resistant stack jacks provide quick stabilization without lifting the frame. Designed for campers, travel trailers and towable RVs, the BEBOBLY stands blend a cast-aluminum square base with thick-walled carbon-steel threaded hardware to resist wear and distribute load evenly. They arrive as a set of four so you can secure all corners or add support exactly where you need it on uneven ground.

How do these jacks secure an RV at the campsite?

The BEBOBLY stack jacks use a screw-adjust mechanism and a broad square base to stop sway and micro-movement once the RV is parked. The triangular support geometry and an anti-loosening groove keep the nut locked in place, preventing gradual settling or rattling during windy conditions or when people move inside.

• Wide cast-aluminum base spreads load and resists sinking.
• Triangular reinforcement under the base increases load-bearing stability.
• Anti-loosening groove secures threaded components against vibration.
• Support gasket improves contact with uneven surfaces for steadier positioning.

Will these jacks handle a large travel trailer?

Each BEBOBLY jack is rated to support up to 6,000 lb as a single support, making them suitable for heavy rigs when used as stabilizers (not as lifting jacks). Their corrosion-resistant materials let them stand up to seasonal use, and the relatively light unit weight makes moving and storing the jacks simple for most owners.

• Single-support capacity: up to 6,000 lb per jack.
• Rust- and corrosion-resistant cast aluminum and carbon-steel components.
• Compact, portable design for easy stowage in RV bays or garage.
• Recommended for stabilization and leveling only, not for lifting the vehicle.

How easy is it to adjust the height and fit uneven ground?

The screw-jack action lets you make fine height adjustments between 11" and 17" for lower-to-ground rigs, with smooth turn operation for precise leveling. If you need extra height, you can safely place approved wood, concrete blocks, or leveling pads beneath the base; the wide footprint keeps the jack from sinking in soft terrain.

• Adjustable height range: 11" to 17" for precise leveling.
• Screw mechanism allows slow, controlled height changes.
• Works with timber or leveling blocks for additional elevation.
• Large base reduces sinking on soft or loose surfaces.

What design details improve long-term reliability?

BEBOBLY focused on load distribution and anti-vibration features to extend service life and reduce noise. Thick-walled threaded components resist bending under repeated use, while the base shape and support gasket cut down on friction noise and movement so interiors stay quiet and cups stay in place.

• Carbon-steel thick-walled hollow bolts for strength and durability.
• Cast-aluminum square base that resists corrosion and spreads pressure.
• Support gasket and anti-noise design reduce cabin vibration and rattling.
• Lightweight construction for convenient transport and storage.

Who is this for: The BEBOBLY RV Stack Jacks 4 Pack is ideal for RV owners who want a portable, robust stabilizing solution to stop sway and improve on-site comfort. Choose these jacks if you camp on mixed surfaces, need fine-level adjustments for a low-to-mid-height trailer, or want corrosion-resistant hardware that’s easy to store and carry. Remember these are stabilization jacks—not replacement lifting jacks—so pair them with appropriate leveling equipment if you need to raise your RV.
