Vacallity RV Trailer Jack Block 1-Pack — HDPE Stabilizer, 16,000 lb Capacity, Stackable

Vacallity RV Trailer Jack Block is a single, heavy-duty HDPE stabilizer designed to give trailer jacks a wide, non-slip base and up to 16,000 lbs of load support.

When you need a reliable, portable platform for scissor jacks, tongue jacks, wheel jacks or leveling pads, this Vacallity one-pack block delivers a sturdy, weather-resistant solution. Molded from high-density polyethylene, the block resists cracking, rotting and water damage while remaining lightweight for easy handling. Its stepped design lets you stack blocks for extra height, and textured surfaces reduce slipping under load so your trailer stays steady during setup and use.

How does this block improve jack stability on uneven ground?

The wide top and bottom footprint spreads weight over a larger surface area to prevent sinking on soft soil, gravel or wet sites. Anti-slip textures and a carefully engineered profile keep the jack foot centered and reduce lateral movement under load. You can stack blocks to fine-tune height without sacrificing stability.

• Large top platform for secure jack seating
• Textured surface reduces slippage under pressure
• Stackable design for incremental height adjustment
• Bottom footprint disperses pressure to avoid sinking

Will it fit my trailer jack and handle heavy loads?

The Vacallity block is compatible with a wide variety of jack types including scissor, tongue, wheel and hydraulic jack feet. Rated for up to 16,000 pounds load capacity, it supports most light- and medium-duty RV and trailer jacks when used properly. Check your jack foot size against the block’s top dimensions to confirm a snug fit.

• Top dimensions: 9.3 x 6.9 x 6.3 inches for secure seating
• Bottom dimensions: 4.7 x 3.2 inches for pressure distribution
• Designed for scissor, tongue, wheel and leveling jacks
• 16,000 lb rated capacity when used as directed

How easy is it to carry, set up, and store on the road?

Made from durable HDPE, the block is both lightweight and rugged—simple to carry between your vehicle and campsite. No tools are required: place the block under the jack foot and lower the jack into position. Its compact shape stacks with identical blocks for neat storage in an equipment bay or trunk.

• Tool-free installation—just position and lower the jack
• Light enough to move by hand but strong under load
• Stackable for compact storage and adjustable height
• HDPE resists weathering, freeze-thaw, and rot for long life

What should I consider before buying this single pack?

One Vacallity block provides a reliable base for many setups, but some situations require multiple blocks for height or extra load distribution. Confirm the jack foot dimensions and your typical ground conditions—soft or unstable sites may benefit from additional blocks. If you frequently set up on uneven terrain, consider purchasing more than one pack to create a customized support stack.

• Ideal as a single stabilizer or combined into a stacked set
• Assess ground firmness and required height before relying on one block
• Pairs well with leveling pads or additional Vacallity blocks
• Store stacked to save space in your RV bay or trunk
