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

WELLUCK RV Stabilizers Jacks 4 Pack are adjustable aluminum screw jack stands that prevent sway and steady travel trailers and campers, each supporting up to 6,000 lbs and extending from 11" to 17".

If you tow or camp with an RV, trailer, or camper, unstable movement and sway are constant annoyances. These WELLUCK stack jacks are built to reduce rocking, stop small shifts, and give a firmer footprint when parked, using a cast-aluminum base combined with carbon-steel hollow bolts for strength without excessive weight. The set of four stores compactly and installs without complex tools — useful for routine leveling, temporary maintenance, or adding stability when the ground is uneven.

How do these jacks stop my camper from rocking?

Stability comes from a wide contact base and a screw-driven lift that eliminates lateral play. When you raise each jack to the chassis, the reinforced square bracket and triangular lower connection spread load and resist sideways motion.

• Cast-aluminum square base increases contact with the ground for steadying force
• Carbon-steel thick-walled hollow bolts provide high hardness and toughness
• Anti-loosening groove on the nut prevents gradual descent or rattling

Are these jacks strong enough for large RVs and easy to transport?

Each WELLUCK stabilizer is rated to support a single point load up to 6,000 lbs (2.72 tons), making them suitable for large trailers when used as stabilizers rather than primary axle supports. Despite that capacity, the total kit weighs under 8 pounds and nests for compact storage, so transporting them is simple.

• Single-point capacity: 6,000 lbs for robust local support
• Total kit weight below 8 pounds; stackable design for tight storage
• Lightweight materials resist corrosion while preserving strength

How do I set them up and adjust the height safely?

Setup requires no power tools: position the jack under the RV frame, rotate the T-handle to raise the screw until the jack contacts the chassis, then secure the nut into the anti-loosening groove. The screw adjusts from 11" to 17", and you can use a wood or concrete block under the base for additional elevation.

• Screw-operated T-handle gives controlled, gradual lift
• Adjustment range: 11" minimum to 17" maximum; add blocks for extra height
• Embedded nut and groove lock the jack at set height to prevent unwinding

What features improve durability and reduce noise when parked?

Durability comes from corrosion-resistant materials and reinforced edges that resist deformation under load. The support gasket and square bracket design increase contact area and stabilize the RV, reducing creaks, friction, and cup-spill incidents when people move inside the vehicle.

• Anti-corrosion cast aluminum and treated carbon steel for long service life
• Support gasket and reinforced edges reduce slipping and rattling
• Triangular bottom connection distributes load and strengthens the base

Who this is for: WELLUCK RV Stabilizers Jacks are ideal for RV owners, caravaners, and trailer maintenance crews who want a lightweight, tough, and easy-to-store set of screw jacks to reduce sway and stabilize camp life. They suit anyone needing temporary support during repairs, tire changes, or whenever a firmer, quieter parked vehicle improves comfort and safety.
