OULEME Trailer Jack Block 15,000 lb Leveling Block — 8.5" Pad Fit, 1-Pack, Anti-Slip Interlocking

OULEME Trailer Jack Block is a heavy-duty, interlocking leveling block that supports up to 15,000 lbs and fits 8.5" pads, round and square jack feet, tongue stands, wheels and scissor stabilizers.

When you need a reliable, portable base for your RV, camper, travel trailer or fifth wheel, this single OULEME jack block offers a compact, high-strength solution. Made from high-density polypropylene, the block resists crushing and deformation while the anti-slip base and interlocking grooves make stacking stable and predictable. It’s sized to work with common 8.5" jack pads and also accepts smaller or round feet and tongue wheels, letting you adapt to uneven ground, soft soil or campsite gravel.

How does this block help stabilize my trailer on uneven ground?

The block spreads load across a larger footprint to reduce sinking and tilting, giving your tongue jack, scissor stabilizer or wheel a firmer base. Interlocking grooves and a textured base keep stacked layers from shifting under load.

• Supports up to 15,000 pounds per block for heavy rigs.
• 10"×10" bottom footprint disperses pressure on soft surfaces.
• Anti-slip base and interlock features secure multi-layer stacks.

Will it fit my jack, wheel or stabilizer?

This block is designed to accept a wide variety of jack foot shapes and tongue wheels: square pads, round feet up to 9" and 2" tongue jack posts all seat securely. The top surface measures 8.5" to match common jack pads while the cavity and contact shapes accommodate other styles.

• Top pad area: 8.5" × 8.5" — fits standard jack pads.
• Accepts round jack feet up to 9" diameter and 2" tongue posts.
• Works with scissor stabilizers and 6×2" tongue jack wheels.

How do I stack and transport multiple blocks safely?

Blocks stack securely thanks to interlocking grooves; the anti-slip base reduces lateral movement so you can build height without instability. When transporting, the lightweight polypropylene construction reduces bulk while remaining crush-resistant.

• Height per block: 4.85"; double-stacked height: 8.2" for more lift.
• Interlocking connectors prevent slippage under load.
• Durable but lightweight for easy carrying and storage.

How long will the block last and handle outdoor use?

Manufactured from high-density polypropylene, the block resists deformation, cracking and long-term compression under heavy loads. It’s designed for repeated campsite use and built to withstand UV exposure and moisture when stored or used outdoors.

• Crush-proof polypropylene resists permanent compression.
• Engineered to tolerate repeated stacking and loading cycles.
• Low-maintenance — rinse off mud and debris, store dry when possible.

Who is this for: The OULEME Trailer Jack Block is ideal for RV owners, camper and fifth-wheel travelers, weekenders with travel trailers, and anyone who needs a dependable, portable leveling base. It suits those who camp on soft grass, gravel or uneven ground and want a compact, stackable option that fits common 8.5" jack pads, round feet, tongue wheels and scissor stabilizers.
