BEBOBLY RV Screw Jack Stabilizers 4-Pack — 11–17 in Adjustable Aluminum, 6,000 lb Support

BEBOBLY RV Stack Jacks 4 Pack are lightweight aluminum screw jack stabilizers that provide steady, adjustable support for RVs and travel trailers from 11" to 17" without lifting your rig.

These versatile jack stands are engineered to reduce sway and movement when your RV, camper, or travel trailer is parked. Built with a cast aluminum square base and thick-walled carbon steel hardware, each jack balances strength and portability. They’re designed for stabilization rather than vehicle lifting, so you can set up a stable living space at campsites, rest stops, and driveways.

How do these jacks keep my RV stable?

The BEBOBLY screw jacks distribute load evenly using a wide square base and a triangular internal support structure. An anti-loosening groove helps lock the nut securely in place, and a support gasket increases contact area to reduce rocking. Together these features minimize swaying and vibration when people move inside the RV.

• Wide cast-aluminum square base for improved pressure distribution
• Triangular reinforcement resists bending under load
• Anti-loosening groove secures adjustments during use
• Support gasket increases grip and reduces slippage

What size range and weight can each jack handle?

Each BEBOBLY jack adjusts smoothly from 11" to 17" to suit lower-to-mid-height rigs. The thick-walled carbon steel screw and hardware are rated to stabilize loads up to 6,000 pounds per jack. Note that these jacks are intended to hold and steady the camper—not to lift it for maintenance.

• Adjustable height: 11" to 17" per jack
• Rated support: up to 6,000 lbs per jack
• Light overall weight keeps each unit under 8 lbs for portability
• Can be paired with blocks for extra height when needed

Are these jacks durable and weather resistant?

Materials were selected for a balance of strength and corrosion resistance: cast aluminum bases resist rust while the carbon steel screw provides structural integrity. The components are built to withstand outdoor conditions encountered during travel and storage, helping maintain reliable performance season after season.

• Cast aluminum base resists rust and reduces overall weight
• Carbon steel, thick-walled screw for long-term strength
• Finish and engineering reduce wear from repeated use
• Portable design eases handling and storage between trips

How easy are these jacks to use and transport?

BEBOBLY stack jacks are hand-operated and require no special tools to set the desired height; simply turn the screw to extend or retract. Each jack is compact and light enough to carry and stow in most RV compartments, making them practical for weekend getaways or extended travel. For additional height, you can place a block under the base rather than altering the jack design.

• Tool-free, screw-driven adjustment for quick setup
• Compact footprint fits common storage spaces in RVs
• Lightweight units keep overall carry weight low
• Works with common blocks for added elevation when required

Who is this for: BEBOBLY RV Stack Jacks 4 Pack are suited for RV owners, families, and solo travelers who need a reliable, portable stabilization solution for campers and travel trailers. If you want to reduce interior sway, create a steadier cooking and sleeping area, and carry a low-weight set of stabilizers that store easily, these jacks are built to fit those needs without serving as a lifting device.
