GEARBONE Trailer Jack Block Four Pack — Heavy-Duty RV Leveling Pads, 40,000 lbs

Universal RV leveling base you can trust

When parked on uneven ground or in challenging outdoor conditions, the GEARBONE Trailer Jack Block Four Pack provides a reliable, modular base for your RV. Designed to work with virtually any jack setup—trailer tongue jacks, wheel jacks, 9" fifth wheel hydraulic jacks, and scissor stabilizers—these blocks offer a single, adaptable solution for leveling and stabilizing your rig. With a robust capacity of up to 40,000 lbs, you can approach setup with confidence, knowing you have a solid footing beneath your jacks and stabilizers.

Key benefits that fit real-world needs

• Universal fit and secure stacking: modular pads stack to the desired height, improving leveling accuracy and reducing jack extension for stability on varied terrain.
• Heavy-duty performance: crafted from high-strength polymer to handle heavy RV loads without cracking or deforming, even on soft ground.
• Outdoor-ready durability: UV-aging additives and a resistant surface keep the pads looking and functioning well through sun, dirt, oil, and weather.
• Portable and simple to use: lightweight design with a straightforward stacking and retrieval process, plus a storage bag for quick transport between stops.

Real-world use cases

• Stabilizing a tall tongue jack on uneven gravel or dirt, minimizing wobble and movement.
• Supporting wheel or hydraulic jacks in soft ground where solid contact is hard to achieve.
• Leveling a trailer on sloped surfaces while keeping the rig steady during setup and teardown.
• Using the blocks with scissor stabilizers for added baseline stability during roadside stops or camping

What you get and how to use

• Pack contents: four heavy-duty leveling pads plus a convenient storage bag for portability.
• How to use: place under the jack base, stack to the desired height, ensure flat contact with the ground, and retrieve with the molded handle or rope to avoid crawling under the rig.

These blocks are designed to be a practical, durable companion for RV setups. They offer possibilities for safer, more stable leveling without claiming guaranteed results, and they’re built to stand up to outdoor use year after year.
