VEVOR Trailer Jack Blocks 4-Pack — 6,000 lb Polypropylene RV Leveling Blocks, 8" Height, Stackable & UV-Resistant

VEVOR Trailer Jack Block 4-pack provides stable, stackable support up to 6,000 lb per block to level and steady RV jacks, posts, and feet.

When you need a compact, durable solution to stop rocking, lower sag, or raise a tongue jack, these VEVOR polypropylene blocks give a high-capacity platform that resists UV, water, oil, and temperature stress. Each 9.65" square block delivers an 8" support height and a broad footprint to spread load and reduce pressure on soft ground. The set of four stacks neatly, installs in minutes, and includes drainage features to protect metal jack components from standing water.

How do these blocks make leveling my RV simpler?

These blocks are designed to be stacked or used singly to fine-tune height beneath a jack or stabilizer. Their uniform dimensions and interlocking surfaces help you build consistent height increments quickly without tools.

• Stackable design for simple height adjustment.
• Wide, 9.65" square base spreads weight evenly.
• Lightweight polypropylene for easy handling.
• Consistent 8" support height per block.

Will they protect my RV jack, foot, or post from damage?

Yes — the solid polypropylene top provides a stable contact surface that prevents metal feet from sinking into soft soil and reduces wear from direct ground contact. Built-in drainage helps avoid water pooling that can accelerate corrosion on jack components.

• Non-porous material keeps moisture off metal surfaces.
• Integrated drainage holes prevent standing water.
• Resistant to oil, tar, and temperature extremes.
• Large footprint reduces ground penetration and rim stress.

How rugged are these blocks and how much weight can each handle?

Each block is engineered from polypropylene T30 to support up to 6,000 lb, making them suitable for many travel trailers, campers, and fifth-wheel setups. The compound and shape are chosen for long service life in outdoor conditions without cracking or deforming under typical loads.

• 6000 lb maximum capacity per block.
• Polypropylene T30 construction for toughness and flexibility.
• UV-resistant formulation guards against sun damage.
• Designed to withstand oil, tar, and dirt exposure.

How quickly can I set them up and store them away?

No tools or complicated steps are necessary: place a block under the jack foot, stack as required, and verify level. When not in use the four blocks nest or stack into a compact bundle that fits in most storage compartments.

• Tool-free placement on any flat or slightly uneven ground.
• Blocks stack securely for transport and storage.
• Lightweight 8.7 kg set for easy carrying.
• Includes simple instruction sheet for quick reference.

Who is this for: These VEVOR trailer jack blocks suit RV owners, weekend campers, and professional haulers who need a reliable way to level and stabilize trailers, fifth wheels, and tow tongues. If you want fast setup, corrosion protection for jack feet, and a high-capacity, weather-resistant platform that stores compactly, this 4-pack is built for those demands.
