bullke Trailer Jack Blocks 4-Pack — 11.5in Wide Recycled Plastic Stabilizing, Stackable RV Jack Pads

BULLKE Trailer Jack Blocks 4-Pack are sturdy, recycled-plastic jack pads built in the USA to stabilize and lift RVs, campers, trailers and various jack types while camping or storing your rig.

These jack blocks give your trailer a broader, non-slip contact point that prevents jacks from sinking into soft ground and protects surfaces from concentrated pressure. Each pack contains four durable pads sized to handle standard tongue, foot, post, scissor and stabilizer jacks. Designed for repeated outdoor use, the blocks stack for extra height, store easily in trailer compartments, and are made from recycled plastic for long life and weather resistance.

How do these jack blocks keep my RV stable on soft ground?

The wide base of each BULLKE pad spreads the jack’s load over a larger surface area, reducing soil compression and the likelihood of the jack sinking. Their textured top helps prevent slippage between the jack foot and the pad, and the stacking feature lets you customize height without makeshift solutions.

• Broad 11.5" width gives better load distribution than a jack foot alone.
• Textured contact surface reduces shifting under load.
• Stackable design adds height in stable increments.
• Suitable for many jack types: tongue, post, foot, stabilizer, scissor.

What weight can each block support and when should I add Flex Pads?

Used correctly on firm, level ground with the jack centered, the blocks support up to 10,000 lbs without additional accessories. If you add BULLKE Flex Pads under the block system, the rated capacity increases to 18,000 lbs. Always follow safe lifting practices and avoid placing blocks on loose gravel or uneven terrain.

• 10,000 lb rating per proper setup without Flex Pads.
• Up to 18,000 lb capacity when combined with BULLKE Flex Pads.
• Only use on stable, level ground—clear debris first.
• Center the jack foot on the block for correct load transfer.

Are these blocks easy to use and store with my camper gear?

Yes—each pad is roughly 11.5 inches wide and 4 inches tall, a size intended to be lightweight yet robust enough for frequent use. Their shape and material make them simple to pick up, position under a jack, or stack for extra height. When not in use they nest or stack neatly for compact storage in toolboxes or under-seat compartments.

• Compact dimensions for easy handling and storage.
• Lightweight recycled plastic construction for portability.
• Stackable profile reduces clutter in storage areas.
• Durable for repeated outdoor deployment and travel use.

How should I prepare the surface before placing a jack block?

Clear the chosen spot of loose rocks, sticks and debris to ensure full contact between the pad and ground. Only place blocks on firm, level areas—avoid slopes, gravel, and markedly uneven surfaces that can compromise stability. If additional bearing surface is needed, consider using multiple blocks stacked or adding a purpose-made support board beneath the blocks on marginal ground.

• Remove debris and level small irregularities first.
• Do not install over loose gravel, rocks, or very uneven ground.
• Stack blocks for extra bearing area or use support boards when necessary.
• Always center the jack foot on the block and recheck stability before loading.

Who is this for: The BULLKE Trailer Jack Blocks 4-Pack is aimed at RV owners, camper and trailer enthusiasts, overlanders, and anyone who regularly parks or stores trailers on soft or variable surfaces. If you want a reusable, compact solution to prevent jack sinking and protect both the jack and ground surface—especially when you travel, camp seasonally, or perform maintenance—these heavy-duty, USA-made recycled-plastic pads provide a reliable, low-maintenance option.
