WELLUCK RV Stabilizer Jacks 4-Pack — Aluminum Screw Jack Stands 11"–17" Adjustable, 6000 lb Single-Point Capacity

WELLUCK RV Stabilizers Jacks are a set of four adjustable aluminum screw jack stands designed to steady and level travel trailers and campers, providing up to 6,000 lb single-point support with 11"–17" height adjustment.

These compact stabilizer jacks combine a cast-aluminum base with thick-walled carbon-steel screw struts to deliver a balance of low weight, corrosion resistance, and heavy-duty capacity. Delivered as a four-pack, they’re intended to reduce sway and movement when your RV is parked, make replacements for worn or missing factory jacks, or serve as temporary supports while changing tires or performing light maintenance.

How do these jacks reduce RV movement and improve campground comfort?

The WELLUCK screw jacks stop side-to-side and fore-and-aft rocking by providing extra anchor points under the chassis. Their square base and reinforced edges spread load downward, while the support gasket increases the contact area for firmer engagement with the ground or vehicle frame.

• Four-point stabilization to limit swaying when people move inside the RV.
• Triangular bottom connection and embedded nut groove prevent loosening under vibration.
• Cast-aluminum bases resist corrosion while keeping overall weight low for storage.

What is the weight capacity and construction of each jack?

Each WELLUCK jack is rated to support up to 6,000 pounds (approximately 2.72 tons) at a single support point. The combination of a cast-aluminum square base and carbon-steel, thick-walled screw strut gives the jack both strength and relative lightness for transporting and storing as a set.

• 6000 lb single-point capacity per jack — suitable for many large RVs.
• Carbon-steel screw strut offers high hardness and toughness for load-bearing use.
• Total kit weight under 8 pounds allows overlap stacking for compact storage.

How does height adjustment and operation work for everyday use?

The jacks adjust from 11" to 17" by turning a T-shaped handle to raise or lower the threaded strut. When additional clearance is needed, placing a block of wood or a concrete pad under the base increases effective height and stability without altering the jack mechanism.

• 11"–17" adjustable travel covers common leveling needs for many campers and trailers.
• T-handle screw operation is manual and straightforward—no power tools required.
• Can be used with pads or blocks beneath the base for extra lift or ground protection.

Are these jacks durable and suitable beyond RV use?

Yes — the design includes rust-resistant materials and reinforced load-bearing points, so these jacks are useful for more than campsite stabilization. They work well as temporary supports for tire changes, equipment stabilization, or any situation requiring a compact, long-lasting support solution.

• Cast-aluminum base reduces corrosion compared with all-steel designs.
• Anti-loosening groove and reinforced edges maintain stability under repeated use.
• Portable, lightweight profile enables use around the workshop or garage.

Who is this for? These WELLUCK RV Stabilizers are designed for RV owners, towable trailer users, and DIYers who need an affordable, portable way to reduce movement and add support under a camper or trailer. They suit those who prefer a manual, durable solution that stores compactly, supports heavy single-point loads, and works for occasional maintenance tasks as well as everyday campsite stabilization.
