Tlaleikejia Trailer Jack Blocks, RV Leveling Blocks Set of 4 — 6000 lb Capacity, Stackable

Tlaleikejia Trailer Jack Blocks are heavy-duty, stackable polypropylene leveling supports that safely hold up to 6,000 lbs per block and simplify stabilizing and leveling your RV or camper.

If you tow a camper or park an RV on uneven ground, reliable jack blocks make setup faster and steadier. These Tlaleikejia blocks are molded from durable polypropylene T30, sized for broad contact with jack pads and designed to stack up to two high so you can dial in height precisely. The set includes four identical supports, each engineered for frequent outdoor use and quick deployment at campsites, driveways, or work sites.

How much weight can each block safely support?

Each Tlaleikejia block is rated to bear up to 6,000 pounds, giving you strong, individual support under a trailer jack or stabilizer. Using two stacked blocks increases reach while maintaining the rated capacity per block when installed properly.

• 6000 lbs capacity per block
• Use single or stacked (up to 2 units) per jack point
• Wide footprint spreads load to reduce sinking on soft ground

What are the dimensions and material—will they fit my trailer jack?

Each block measures 9.65 x 9.65 x 8.03 inches, providing a large, stable surface for most common trailer jacks and stabilizer feet. The polypropylene T30 construction resists impact and weather, while the size accommodates a variety of jack pad shapes without slipping.

• Dimensions: 9.65" x 9.65" x 8.03" per block
• Material: polypropylene T30—durable, weather-resistant plastic
• Designed to fit common round and square jack pads securely

How easy is setup and storage for camping trips?

These jack blocks are built for quick, tool-free placement: set a block under the jack, crank down, and add a second block if more height is needed. When not in use, the blocks nest together or stack flat to save cargo space and keep your gear organized.

• Tool-free, immediate placement and leveling
• Stackable design allows two-unit height adjustments
• Total set weight: 20.39 lbs—easy to carry and store

Will they perform on soft or uneven ground?

The broad base and sturdy polypropylene help distribute weight over a larger area, reducing sinkage on softer surfaces like gravel, grass, or sand. For very soft ground, pair with an additional ground plate or use multiple blocks where needed to increase stability.

• Wide footprint minimizes pressure per square inch
• Durable material resists cracking under load
• Stacking gives adjustable clearance for uneven terrain

Who is this for: The Tlaleikejia Trailer Jack Block set is ideal for RV owners, camper van travelers, and anyone who needs dependable leveling and stabilizing support at campsites, long-term parkings, or work locations. If you want a lightweight, weather-resistant solution that fits most trailer jacks and stacks for extra height, these blocks are a practical addition to your towing toolkit.
