bullke Trailer Jack Blocks 4-Pack - 11.5" Wide x 4" Tall Recycled Plastic RV Leveling & Stabilizing Pads, 10,000 lb Rating

BULLKE Trailer Jack Blocks 4-Pack are heavy-duty, USA-made recycled-plastic pads that stabilize and raise RV, camper, trailer, tongue and 5th wheel jacks for safer, more secure setups.

These jack blocks mount under trailer and tongue jacks to provide a solid, level bearing surface that resists sinking and uneven loads. Constructed from recycled plastic in the USA, each block is sized for easy handling, stacking, and storage, and is designed for repeated outdoor use. The set of four supports a wide range of jack types, from foot jacks to scissor jacks, and works best on firm, level ground.

How do BULLKE jack blocks improve stability during RV setup?

The blocks spread the jack’s load over a larger area, reducing pressure on soft or compacting ground. That means less risk of the jack foot sinking or tilting, and a steadier platform for leveling and repairs. Use them singly or stacked to achieve the height and footprint you need.

• 11.5" wide, 4" tall profile for greater surface contact
• Stackable design lets you adjust height in seconds
• Recycled plastic resists moisture and decay outdoors
• Works with tongue jacks, foot jacks, post jacks, and scissor jacks

What load capacities can these trailer jack pads handle?

The BULLKE blocks are rated up to 10,000 lbs when used alone on firm, level ground with the jack foot centered. When combined with BULLKE Flex Pads, the rated capacity increases to 18,000 lbs under the same correct conditions. Always place blocks on a stable, even surface and follow manufacturer guidance for safe use.

• 10,000 lb rating per set without Flex Pads on firm, level ground
• 18,000 lb rating when used with BULLKE Flex Pads (proper setup required)
• Capacity assumes jack foot centered and stable ground
• Not intended for use on loose rock, gravel, or very uneven terrain

How do I use and care for these recycled-plastic jack pads?

Position the block under the jack foot on cleared, firm ground; if more height or support is needed, stack additional blocks. After use, wipe off mud or debris and store the blocks with your towing or campsite gear. Avoid placing them on unstable substrates like deep gravel or loose rock.

• Clear area of rocks and debris before placing block
• Center the jack foot on the block for best load distribution
• Stack for added height and footprint as necessary
• Wipe clean and store indoors or in a dry compartment

Are these jack blocks durable and suitable for outdoor conditions?

Yes—the blocks are molded from heavy-duty recycled plastic designed to resist rot, moisture, and repeated outdoor use. Built in the USA, they offer a durable alternative to wooden or flimsy plastic pads. Still, using them on the appropriate ground type and avoiding concentrated sharp impacts will extend their service life.

• Proudly made in the USA from recycled plastic for longevity
• Resists moisture, splitting, and rot compared with wood
• Designed for repeated campsite and travel use
• Store away from prolonged high-heat exposure when possible
