OULEME Trailer Jack Leveling Block 2-Pack 15,000 lb - 8.5" Pad Fit, Interlocking Anti-Slip RV Stabilizer Base

OULEME Trailer Jack Block is a heavy-duty, interlocking leveling block set that supports up to 15,000 lb per piece and adapts to square, round, scissor and tongue jacks for safer, stable RV and trailer leveling.

Stop relying on unstable boards or flimsy pads: these two high-density polypropylene blocks provide a robust, crush-resistant base when you need to raise, level or stabilize campers, travel trailers, 5th wheels and tow tongues. Sized to fit an 8.5" jack pad and designed with anti-slip feet and interlocking grooves, the blocks stack securely and resist deformation over repeated use in diverse outdoor conditions.

Will these blocks fit my trailer jack or tongue stand?

Yes — the OULEME blocks are engineered to work with most common jack foot shapes and small trailer wheels. Their top recess accepts 8.5" pads and can cradle square or round jack feet while the 2" tongue post and 6x2" tongue jack wheel also find a stable seat.

• Top dimensions: 8.5" x 8.5" — compatible with many standard jack pads.
• Accepts square and round jack feet, scissor stabilizers, and tongue wheel posts.
• Height per block: 4.85"; stack two for 8.2" total when more lift is needed.

How strong and durable are these leveling blocks?

Each block is rated to support up to 15,000 pounds and is molded from high-density polypropylene to resist crushing and long-term deformation. The construction holds up under repeated loads and outdoor exposure, giving a reliable platform for leveling and stabilization tasks.

• High-density polypropylene resists cracking and compressive failure.
• 15,000 lb support per block provides commercial-strength performance.
• Engineered shape disperses load to reduce localized stress on jack feet.

How do the blocks stack and stay stable on uneven ground?

OULEME blocks feature interlocking grooves that mate securely when stacked, plus an anti-slip base to resist shifting on soft or inclined surfaces. This design reduces wobble and keeps the jack foot aligned through setup and travel.

• Interlocking grooves prevent lateral movement between stacked units.
• Anti-slip textured base increases grip on gravel, dirt, and pavement.
• Compatible with additional OULEME leveling blocks for tailored heights.

What practical advantages will I notice while using these blocks?

You'll get faster, safer setups and more predictable leveling because the blocks provide a solid, repeatable platform for jacks and stabilizers. Their size and stackability let you fine-tune ride height and leveling without improvising with wood or random objects.

• Speeds up campsite setup and tear-down with predictable lift increments.
• Reduces wear on jack feet and tongue wheels by distributing weight evenly.
• Lightweight enough to carry convenient two-pack portability but rugged in performance.

Who is this for? OULEME Trailer Jack Blocks are aimed at RV owners, fifth-wheel and travel-trailer haulers, tow vehicle users and anyone who needs a dependable leveling and stabilizing base in the field. Whether you camp on uneven ground, park on gravel driveways or use scissor stabilizers, these blocks give a durable, stackable solution for lifting and stabilizing jacks, tongue stands and jack wheels without improvisation.
