Hyfico Trailer Jack Blocks 4-Pack — HDPE RV Leveling Blocks, 20,000 lb Capacity with Storage Bag

Hyfico Trailer Jack Block 4 Pack are heavy-duty HDPE leveling blocks that stabilize jacks, wheels and feet on trailers and RVs, supporting up to 20,000 lbs and stacking for compact storage.

When you park a travel trailer, camper, or towable, unstable ground and uneven surfaces make setup slower and less secure. These Hyfico jack blocks provide a low-profile, durable platform that reduces sway, prevents buried or sinking feet, and gives jacks a reliable surface on grass, gravel, dirt, or asphalt. The set arrives with four upgraded blocks and a storage bag designed for convenient transport and neat stacking.

How do these jack blocks improve stability for my trailer or RV?

By creating a solid, non-slip platform under a jack foot, stabilizer, or wheel, the blocks spread load and reduce motion. Their HDPE construction resists crushing and holds shape under heavy pressure, while anti-UV material maintains strength outdoors.

• Distributes weight to prevent sinking into soft ground.
• Compatible with scissor jacks, tongue jacks, stabilizers and post feet.
• Stackable design allows extra height without compromising contact area.

Are these blocks easy to set up and store?

Yes. The blocks are small enough to handle quickly and include side holes that make positioning easier and reduce water pooling. When not in use they nest and stack compactly in the supplied bag for tidy storage in a truck bed or camper bay.

• Side holes for quick alignment and easy lifting.
• Compact stacked footprint to save space in storage compartments.
• Carry bag keeps all four blocks together and protected from dirt.

Will these work on different surfaces and with different jacks?

Designed for versatility, Hyfico blocks provide a stable base on turf, packed gravel, dirt and paved surfaces. Their shape and top contact area accept a wide variety of jack feet and stabilizer pads without slipping.

• Suitable for wheels, jacks, and stabilizer feet on trailers and campers.
• Non-corrosive HDPE tolerates outdoor exposure and wet conditions.
• Stacking in two layers increases height—note rated load per configuration.

How durable are the blocks and what load can they handle?

Manufactured from high-density polyethylene, these blocks resist cracking, UV damage, and corrosion. Each block is built to endure heavy loads; follow stacking guidance because the rated capacity changes when blocks are stacked.

• HDPE construction is corrosion-resistant and recyclable.
• Rated support up to 20,000 lbs for typical single-block placement.
• Two-block stacks reduce the load-bearing capacity per block—use per instructions.
