OULEME RV Leveling Blocks 12-Pack, Blue — Stackable Interlocking Pads, UV-Stable Polypropylene

If you tow a camper, travel trailer or use a jack on uneven ground, having a simple, durable leveling system makes setup faster and steadier. These OULEME blocks come as a kit of ten interlocking flat blocks plus two thin top blocks, so you can build a level surface in small increments. Constructed from UV-stabilized polypropylene and engineered with extra thickness and density, the set is built for repeated outdoor use and resists weathering and deformation.

How do these blocks help me level a camper or trailer?

They stack to raise a wheel, stabilizer, or jack in controlled one-inch increments until your rig sits level. Interlocking edges keep the stack aligned under load, and the thin top plates provide a low-profile final surface for tires or jacks.

• 12-piece kit: ten 1.5" tall interlock blocks plus two 0.7" top blocks for fine adjustments
• Blocks measure 8.5" x 8.5" for broad contact area and improved stability
• Stacking permits small, repeatable height increases to prevent tipping or slipping

Are these leveling blocks durable enough for outdoor, long-term use?

Yes — the blocks are molded from polypropylene with anti-UV additives, so they withstand sun exposure and seasonal storage without rapid brittle failure. The extra structural thickness and increased density reduce flexing and compression under weight compared with thin plastic alternatives.

• Polypropylene construction with UV-aging additives for longer outdoor life
• Reinforced thickness and density resist compression from heavy trailers
• Easy to clean and store; resistant to rot and rust unlike wood or metal

How do I use the blocks with jacks and stabilizers safely?

Place blocks under wheels, stabilizer legs, or scissor jacks where they make full contact; interlock pieces as needed to reach the target height and always check for firm, level support before exiting the vehicle. Use the flat top pieces for a stable saddle surface beneath a jack or stabilizer foot.

• Position on firm ground; add base blocks before stacking to spread load
• Interlock blocks so the stack stays aligned under pressure
• Finish with a top plate for a low-profile, secure contact point

What comes in the pack and what are the exact sizes?

The OULEME kit contains 12 pieces total: ten interlocking leveling blocks and two thinner top blocks. Each interlock block measures approximately 8.5 inches long by 8.5 inches wide and 1.5 inches tall; top blocks are the same footprint but about 0.7 inches tall for precise final adjustments.

• 10 interlocking blocks — 8.5" L x 8.5" W x 1.5" H each
• 2 top blocks — 8.5" L x 8.5" W x 0.7" H each for fine leveling
• Includes a carrying bag (compact storage and transport)

Who is this for? The OULEME 12-pack leveling blocks suit RV owners, weekend campers, van lifers and anyone using trailer jacks or stabilizers who needs a compact, reusable leveling solution. If you frequently set up on gravel lots, uneven campsites, driveways or soft ground and want simple height control without bulky ramps or noisy hydraulic tools, this kit offers portable, weather-resistant support that stores easily in your vehicle.
