bullke Trailer Jack Blocks 4-Pack – USA-Made Recycled Plastic RV Leveling & Stabilizing Pads, 11.5in x 4in, 10,000 lb Capacity

BULLKE Trailer Jack Blocks are a 4-pack of heavy-duty, USA-made recycled plastic pads engineered to stabilize and level RVs, campers, trailers, and jack systems. These stacking jack blocks provide a compact, durable solution for supporting tongue jacks, post jacks, foot jacks, scissor jacks and stabilizer jacks during setup and storage. Built from recycled plastic in the United States, each block is sized for easy handling and designed to resist outdoor wear so you can rely on predictable footing at campsites, driveways and storage areas.

How much weight can a single BULLKE jack block support?

Load capacity depends on whether you pair the blocks with BULLKE Flex Pads and on correct placement. Used alone and placed on firm, level ground with the jack foot centered, the blocks are rated up to 10,000 lbs; when combined with the Flex Pads and used properly, the system rating increases to 18,000 lbs.

• 10,000 lb rating per block on firm, level surfaces without Flex Pads.
• Up to 18,000 lb system rating when used with BULLKE Flex Pads.
• Ratings assume centered jack foot and stable substrate.

What surfaces are appropriate for these jack blocks?

These blocks are intended for use only on firm, level ground. They are not designed for soft, uneven, or loose substrates such as gravel, rock piles or saturated soil — clearing and prepping the area before placement is important for safety and performance.

• Use on packed dirt, concrete, asphalt or other firm, level surfaces.
• Avoid placement over gravel, rocks, sloped ground, or soft/muddy areas.
• Always clear debris and confirm the jack foot is centered on the block.

How do I handle, stack and store the BULLKE 4-pack?

Each block is about 11.5 inches wide and 4 inches tall, making them light enough to carry and simple to stack for extra height. The design allows easy positioning under jack feet and compact storage in bays or with other RV gear when not in use.

• Individual block dimensions: ~11.5 inches wide by 4 inches tall.
• Stack blocks to achieve required height — ensure stable, level stacking.
• Compact footprint for storing in compartments, storage bins or a trailer tongue box.

Why choose recycled-plastic BULLKE blocks made in the USA?

These blocks combine durability and sustainability by using recycled plastic while being manufactured domestically for consistent quality control. The material resists weathering, is easy to clean, and stands up to repeated seasonal use so you get reliable performance without frequent replacement.

• Recycled-plastic construction resists cracking, rot and corrosion.
• U.S. manufacturing supports consistent build quality and supply traceability.
• Low-maintenance: rinse clean and store dry between uses.

Who is this for? If you own an RV, camper, fifth wheel, trailer or frequently use post, tongue, foot or scissor jacks, the BULLKE Trailer Jack Blocks 4-Pack offers a portable, heavy-duty option for creating a stable base on firm ground. These blocks are aimed at RV owners, weekend campers, tow vehicle operators and fleet managers who want a reusable, weather-resistant solution that’s easy to carry, stack and store. For best results, use them on prepared, flat surfaces and pair with BULLKE Flex Pads when higher load capacity is required.
