OULEME Trailer Jack Blocks for RV & Camper — 2-Pack Heavy-Duty Recycled-Plastic, 15,000 lb Capacity, 6.3" Height

OULEME Heavy Duty Trailer Jack Block is a reinforced recycled-plastic support pad set designed to stabilize RV tongue jacks, round/square jack feet, and scissor stabilizers with up to 15,000 lb capacity per block.

When you need a dependable base under your camper or travel trailer, these OULEME jack blocks give a low-profile, high-strength platform that resists sinking on soft ground and prevents jack feet from gouging concrete or asphalt. The pair is sized to work with common jack posts, wheels, and stabilizer pads and can be stacked for added height and footprint when required. Built from dense recycled plastic with anti-slip features, they balance portability with rugged load capacity.

How do these jack blocks keep my trailer stable on soft or uneven ground?

The blocks broaden the contact area beneath a jack foot or wheel to distribute weight and reduce ground pressure, which cuts the chance of sinking. Their dense construction resists deformation under load, while the grooved top and recessed post hole help lock jacks in place.

• Bottom footprint 11.2" x 8.8" spreads load to reduce sinkage
• Grooved top prevents lateral slip when stacked
• Reinforced post hole with iron plate prevents post wear and movement

Will these blocks fit my trailer’s tongue jack, wheel jack, or stabilizer?

OULEME blocks are designed to be versatile: they accept square jack feet, round jack plates up to about 9" diameter, common 2" tongue jack posts, and 6"x2" wheel-style jack pads. The shape and dimensions accommodate most consumer RV and camper jacks.

• Top measures 9.3" x 7" to fit many jack plates and wheels
• Recessed hole designed for 2" tongue jack posts
• Works with scissor stabilizers and other standard stabilizer feet

How much height and load capacity do these blocks provide?

Each block stands 6.3" tall and carries a rated capacity up to 15,000 lb. You can double-stack two blocks to gain additional height (about 11.1") when more clearance or lift is required. Stacking is supported by the interlocking groove design for improved stability.

• Single-block height: 6.3" for low-profile support
• Double-stacked height: 11.1" when extra lift is needed
• Individual load rating: supports up to 15,000 pounds per block

What materials and construction features make these blocks durable?

Constructed from dense recycled plastic, the blocks resist cracking and absorb heavy loads without significant flex. An iron wear plate embedded in the recessed post hole protects high-contact areas from abrasion, extending service life under regular use.

• High-density recycled plastic resists weathering and deformation
• Iron plate reinforcement in the post hole prevents premature wear
• Thick, solid walls and anti-slip top grooves for secure stacking

Who is this for: These OULEME jack blocks suit RV owners, camper and travel trailer enthusiasts, installers, and anyone who needs reliable support for tongue jacks, wheel jacks, and stabilizers. They’re particularly useful for boondocking or seasonal parking on soft soil, gravel, or asphalt, and for technicians who require a portable, heavy-duty pad that resists wear and prevents ground damage.
