OULEME RV Leveling Blocks 12-Pack Gray — Stackable Interlocking Polypropylene Pads with Carrying Bag

OULEME 12 Pack RV Leveling Blocks are stackable, interlocking polypropylene pads designed to quickly and safely level campers, trailers, and jack stands.

These durable gray leveling blocks give you a customizable, high-strength platform that resists UV damage and handles the load of RV wheels and jacks. The set includes ten interlocking 1.5-inch blocks and two thinner top blocks, letting you build the exact height needed and finish with a stable, low-profile cap. They nest and lock together for secure stacking and stow compactly in the included carrying bag for travel.

How much height can I get from these leveling blocks?

You can combine blocks to reach the height needed for most RV leveling tasks. Each standard block is 1.5 inches tall while the two top blocks are 0.7 inches, so stacks are modular and precise.

• Ten interlocking blocks at 1.5" each for up to 15" of incremental height.
• Two 0.7" top blocks for finishing or fine adjustments.
• Interlocking design prevents slipping between layers under load.

Are these blocks strong enough for heavy trailers and jacks?

Yes — the blocks are molded from reinforced polypropylene with UV-stabilizing additives, giving them increased density and structural thickness for sustained load-bearing. They’re built to support trailer stabilizers, jacks and RV wheels without cracking in normal use.

• High-density polypropylene construction for long-lasting strength.
• Anti-UV additives reduce degradation from sun exposure.
• Thick walls and ribbed design distribute weight evenly across surfaces.

How do the interlocking features and top blocks improve stability?

The blocks have mating surfaces that fit together to form a single secure stack, preventing sideways movement or shifting when you drive onto them or set down a jack. The thinner top blocks serve as low-profile finishing pieces that create a flatter contact area for stabilizers and jacks.

• Raised ridges and matching cavities lock layers in place.
• Top blocks provide a level cap to protect stabilizer feet and jacks.
• Stacking system reduces rocking and improves load distribution.

How portable and easy to store are these leveling blocks?

The full 12-piece kit fits into the supplied soft carrying bag so you can keep the set organized and ready for travel. The blocks are lightweight and stack compactly, making them easy to store in RV compartments or a vehicle trunk.

• Includes a durable carrying bag for neat storage and transport.
• Blocks nest and stack flat to minimize space usage.
• Lightweight polypropylene makes them easy to load and carry.
