OULEME RV Leveling & Stabilizer Jacks 4-Pack — Aluminium 11"–17" Height, 7,900 lb Each

OULEME 4PK RV Leveling & Stabilizer Jacks are a four-piece aluminum stack jack set that provides corrosion-resistant support and manual height adjustment from 11" to 17", with each jack rated for up to 7,900 lb.

These camper stack jacks combine lightweight aluminum construction with a high load rating to stabilize travel trailers, motorhomes, and fifth wheels without the bulk of hydraulic or electric systems. Designed for frequent campers and seasonal storage, the set includes rubber cushions and mounting nuts to reduce vibration, noise, and wear on vehicle frames. The compact, stackable design makes them easy to carry and store while delivering a solid footprint under jack points.

How do these jacks improve trailer stability at a campsite?

The OULEME stack jacks transfer load from suspension and chassis points to the ground, reducing sway and bounce when people move around inside the camper. Their wide base and durable aluminum casting create a steady support under static loads.

• Four jacks provide balanced support at multiple corners or landing gear points.
• Rubber pads cushion contact and dampen noise and vibration.
• High compressive strength resists deformation under heavy loads.

What adjustment range and load capacity should I expect?

Each jack adjusts from 11" to 17" (280–435 mm) to match varying chassis heights and ground conditions. With a 7,900 lb rating per jack, the set suits many recreational vehicles when used as stabilizers or temporary stands.

• 11"–17" height range covers typical RV frame clearances and leveling needs.
• 7,900 lb capacity per jack supports heavy campers when distributed properly.
• Threaded adjustment gives precise, step-free positioning for fine leveling.

What materials and extras are included for long-term use?

Constructed from premium-grade aluminum, these jacks resist rust and are lighter than comparable steel options, making them practical for towing and storage. The package includes four mounting nuts and four rubber cushion pads to protect contact points and reduce wear on both jack and vehicle.

• Casting-grade aluminum reduces corrosion risk and keeps overall weight down.
• Cushion pads protect frame feet and minimize metal-on-metal contact.
• Included nuts simplify installation and ensure a secure threaded connection.

How do I use and maintain the OULEME camper jacks safely?

Use these stack jacks on firm, level ground and place them under designated jack or stabilizer points only. Avoid using them as permanent supports for extended storage without additional safety measures like wheel chocks or cribbing, and inspect components periodically for damage.

• Set on compacted gravel, concrete, or a level paved surface for best performance.
• Add wooden or plastic cribbing under the base for extra load distribution on soft ground.
• Clean threads and apply appropriate lubrication to prevent gumming and ensure smooth adjustment.

Who is this for: The OULEME 4PK RV Leveling & Stabilizer Jacks suit weekend campers, full-time RVers, and storage preparers who need portable, rust-resistant supports that are easy to carry and adjust. They are ideal for owners who prefer a manual, durable solution to reduce movement in their camper without adding heavy or complex equipment. If you tow frequently and want a reliable, compact set of stack jacks that includes protective pads and fastening hardware, this product is designed for your needs.
