RVMATE 12 Pack Leveling Blocks

RVMATE’s 12-pack offers heavy-duty leveling blocks with stackable height adjustments. These blocks are designed to secure RVs on uneven ground and reduce movement while parked. They use an interlocking construction to prevent direct tire contact with the block body, preserving tire tread. Best for campers who need a robust, modular system and frequent stacking for varied sites. Limitation: the top-to-bottom height combination should be checked to ensure compatibility with your tongue jack height.
OX BLOX Heavy Duty Trailer Jack Block

With a 10,000 lb capacity per block and stackable design, they support tongue jacks, stabilizers, and other jacks on gravel, grass, dirt, or pavement. Best for heavy setups that require consistent performance across surfaces. Be mindful of the need to correctly align stacked blocks to avoid wobble when additional height is added.

ROBLOCK’s 6″ high block prioritizes durability with a high-performance polymer and anti-UV additives. It supports a wide range of jacks and stabilizers and features a stackable height design. Best for RV owners who want a sturdy, weather-resistant option that reduces movement on uneven terrain. Limitation: ensure the top-height combinations don’t exceed the block’s designed load path to avoid deformation under heavy loads.

Made from polypropylene with anti-UV additives for durability. Best for campers who want a modular, portable solution with convenient storage.

Buying Guide: Key Purchase Considerations
What capacity do you need? For most travel trailers and small campers, blocks rated from 6,000 to 10,000 lbs per block cover common tongue jack and stabilizer loads. If you own a larger RV or fifth wheel, prioritize higher capacity and stable, interlocking designs to minimize wobble.
How important is height adjustment? Interlocking and stackable systems let you tailor height precisely. Choose blocks that offer clear stacking limits and maintain stability when added height is required on uneven sites.
What surface are you camping on? Some blocks perform better on grass, gravel, dirt, or pavement. Look for durable polymers with weather resistance and fixed contact surfaces to prevent slippage or damage to tires.
Are storage and portability priorities? Sets with carrying bags or compact, uniform shapes are easier to store in a trailer or truck bed. Confirm that the bag or case fits your gear and that blocks stack securely for transport.
Is compatibility a concern? Ensure the blocks fit your tongue jack, stabilizers, or 5th wheel hardware. Some blocks are designed for universal use, while others specialize for certain jack types. Check the top surface design and the interlock compatibility before purchase.
Frequently Asked Questions
- What height should trailer leveling blocks add? Choose height based on the unevenness of your site; most sets offer 1–1.5 inch tall blocks per layer and allow stacking up to higher heights.
- Can I use any block with any tongue jack? Some blocks are universal, but verify compatibility with your specific tongue jack model to avoid unstable setups.
- Are interlocking blocks worth it? Interlocking designs reduce movement and provide a more stable base, especially on uneven ground.
- How many blocks should I carry? A small kit (4–6 blocks) covers common uneven sites; larger rigs may require 8–12 blocks or more for precise leveling.
- Do I need a carrying bag? A carrying bag or storage case helps protect blocks from UV exposure and makes transport easier, especially for frequent travelers.
- What is the best way to stack blocks? Place blocks on firm ground, align edges, and stack evenly. Avoid leaning or angled stacking to prevent tipping or crushing.
