PAULINN RV Leveling Blocks 12-Pack — Interlocking Heavy-Duty Blue Blocks for Wheels & Jacks

When you park on uneven ground, these interlocking plastic blocks give you a customizable, compact way to raise and stabilize RV wheels and jacks. The kit is built from high‑density reinforced material that resists UV, water, and temperature extremes, and it stores flat for easy packing in cargo bays or closets.

How do I build the stack to get the right height?

Stack the blocks in a pyramid or linear arrangement to reach the height you need. Regular blocks measure 8.5" x 8.5" x 1.25" and the two top blocks are 8.5" x 8.5" x 0.7", so mixes of these let you fine‑tune elevation.

• Each regular block adds 1.25 inches of nominal thickness.
• Top blocks add 0.7 inches for a lower finishing surface.
• Due to interlocking geometry, adding extra blocks increases height in ~0.8" increments after the first layer.
• Do not stack more than five blocks high; recommended maximum usable height is 4.45 inches.

Which wheels, jacks, or axles can this kit support?

These blocks are designed for wide compatibility: single and dual wheels, tongue or stabilizer jacks, fifth‑wheel jacks, and tandem axles all work with the PAULINN blocks. They are tough enough to support heavy loads while protecting tires and jack feet from sinking on softer ground.

• Suitable under single and dual RV wheels.
• Works as a base for hydraulic, tongue, and stabilizer jacks.
• Can be used with jack pads and tandem axles for extra stability.
• Reinforced high‑density construction resists crushing and weathering.

How easy is it to use and pack away?

Setup takes seconds: align the directional markers, stack to the desired height, and drive onto the blocks. When done, separate or nest the pieces and secure them with the included Velcro straps to keep your storage area tidy.

• Blocks interlock for safe placement and easy stacking.
• Includes two Velcro straps for compact storage and transport.
• Lightweight, weather‑resistant material cleans easily and dries fast.
• Directional markers help you orient stacks for optimal load distribution.

Whether you run a travel trailer, motorhome, or fifth wheel, the kit suits people who need a reliable way to stabilize on gravel, grass, or uneven pavement without carrying bulky metal ramps.
