VEVOR Trailer Jack Blocks 6" High RV Leveling Blocks, 2-Pack Heavy-Duty 6000 lb Capacity, Non-Slip Polypropylene

VEVOR 6" Trailer Jack Blocks are heavy-duty polypropylene leveling supports that give trailer jacks and stabilizer legs a wider, non-slip base and hold up to 6,000 lbs per block.

When parking on soft, uneven, or sloped ground, small jack feet can sink, tilt, or slip — causing instability and damage. These 6-inch high VEVOR jack blocks expand the bearing surface for round or square legs, trailer support wheels, and insertable jacks. Built from reinforced PP, each block is rated for 2,722 kg (6,000 lbs) so you get dependable support whether you’re overnighting on grass, gravel, sand, or packed dirt.

How do these blocks improve jack stability on soft ground?

The tall cylindrical shape increases contact area, reducing pressure on the substrate so jacks don’t sink or tip. Their textured top surface helps prevent slipping while the hollow-but-ribbed design resists deformation under heavy loads. You’ll see better leveling performance and reduced risk of jack leg damage.

• 6" height spreads load across a larger footprint to limit sinking.
• Textured top keeps jack feet from sliding during vehicle movement.
• Ribbed interior structure preserves shape under repeated use.

Will these work with my trailer’s different jack types?

Yes — the blocks are made to accept both round and square metal jack legs, plus trailer support wheels and insertable legs. Their universal opening and sturdy walls accommodate common jack sizes without rearrangement. This makes them a practical choice for fifth-wheels, travel trailers, and many motorhomes.

• Universal fit for round and square jack legs and support wheels.
• Generous opening accepts insertable or threaded jack tubes.
• Two-block set lets you support multiple points or carry a spare.

Are these blocks durable and safe in different weather conditions?

Manufactured from robust polypropylene, the blocks resist cracking, moisture absorption, and most road salts. Their non-slip, matte finish maintains grip on icy, wet, or sandy surfaces, and the UV-stable material reduces sun-related degradation. These features help ensure consistent, long-lasting performance across seasons.

• Reinforced PP resists weathering, corrosion, and salt exposure.
• Non-slip texture for reliable grip on wet or smooth ground.
• UV-resistant formulation keeps blocks functional outdoors.

How else can I use these blocks around camp or in the garage?

Beyond supporting jacks, the VEVOR blocks serve multiple practical roles — from temporary seating to motorcycle stands or steps when needed. Their hollow, strong form is stable under weight yet easy to carry, so they work as multi-purpose gear for travel and upkeep tasks. The stackable design also helps with storage and height adjustment.

• Use as a low seat or stepping platform while camping.
• Support small motorcycles or garden machinery for maintenance.
• Stackable for incremental height increases and compact storage.

Who is this for: These VEVOR 6" Trailer Jack Blocks suit RV owners, tow vehicle operators, and weekend campers who need reliable, portable support on uneven or soft surfaces. They’re a practical accessory for fifth-wheels, travel trailers, and Class A / C motorhomes, and they also benefit DIYers who want a robust, multi-use block for vehicle maintenance, camping setups, or emergency roadside use.
