RV Stack Jacks 4 Pack Screw Jack Stands for RV Leveling - Stable 11

In this review of the RV Stack Jacks 4 Pack the bottom line is straightforward: these jacks are aimed at RV owners who need a lightweight, corrosion-resistant way to stop sway and stabilize a camper or trailer while parked. The single biggest reason to buy is the combination of compact portability and surprisingly high per-jack capacity: cast aluminum bases with carbon steel bolts give a stable support rated up to 6,000 lbs per jack while keeping the set under 8 lbs for transport. They are a stabilization solution rather than lifting gear.

Key Features

• 4-pack included: Four identical stack jacks let you stabilize all corners of an RV, trailer, or camper without mixing and matching different supports.
• Lightweight construction: Cast aluminum bases and hollow carbon steel bolts keep each jack light for carrying while remaining robust on site.
• High per-jack capacity: Each jack is described to support up to 6,000 lbs, making them suitable for larger rigs that need secure unloading and anti-sway support.
• Adjustable height: Smooth adjustment from 11in to 17in covers lower-to-the-ground rigs and lets you fine-tune stabilization; additional blocks can be used for more height.
• Stability-focused design: Wide square bases, a triangular support shape and an anti-loosening groove work together to distribute pressure and keep the nut from backing off under load.
• Corrosion resistance: Materials and finishes resist rust, which helps maintain function and appearance through seasonal use.

Who It's For

These jacks are best for RV and travel trailer owners who need a portable stabilization system that reduces sway and movement while parked at campsites or storage. They suit people who value light carry weight and simple mechanical adjustment over hydraulic or permanent leveling systems.

They are not intended for anyone who needs to lift a vehicle or perform major chassis work; the product is explicitly for stabilization only. Those who require exact leveling for heavy modifications or who prefer motorized, automatic leveling should look at powered jack systems instead.

Pros & Cons

Pros

• High stated load capacity per jack provides confidence when stabilizing larger trailers.
• Very light total weight makes the set easy to stow and carry between sites.
• Thoughtful base and support gasket reduce movement and friction noise for quieter evenings in the RV.
• Smooth, simple height adjustment from 11in to 17in fits many lower rigs without added blocks.

Cons

• Designed for stabilization only, these jacks should not be used to lift an RV; users must rely on primary lifting gear for maintenance.
• Additional height requires stacking wood or concrete blocks rather than built-in extension beyond 17in.
