KIKIRV 6" Trailer Jack Block — 40,000 lb RV Leveling Pad, Stackable Heavy-Duty Polymer

KIKIRV's 6" Height Trailer Jack Block is a stackable, heavy-duty polymer pad designed to support up to 40,000 pounds and stabilize RV jacks, tongue jacks, scissor stabilizers, and 5th wheel jacks.

When you park a trailer or RV on uneven ground, a stable, durable base under the jack prevents sinking, wobble, and unpredictable shifting. This single 6-inch block from KIKIRV is built from a high-performance polymer blend that resists UV, oil, water, heat, stains, and weathering so it keeps working even after repeated outdoor use. The pad’s stackable profile lets you increase height safely while its locking stacking mechanism reduces lateral movement. Built-in carrying holes, a rope, and drainage slots make it simple to move, stow, and keep dry between trips.

How does the 6" jack block improve trailer stability on soft ground?

By widening the contact area beneath a jack head, the block spreads the load so the jack won’t sink into dirt, gravel, or soft grass. The textured top surface holds the jack foot steady and the pad’s rigidity prevents bending under heavy loads.

• Supports up to 40,000 pounds per pad for heavy trailers and RVs
• Large footprint distributes weight to avoid sinking
• Textured surface prevents jack foot slippage and rotation
• Rigid polymer resists deformation under load

Can I stack these blocks to reach greater height safely?

Yes — the blocks are designed to lock together so you can build additional height without unstable shifting. Each pad’s interlocking features keep layers aligned and maintain load-bearing capacity when stacked.

• Stackable design increases height beyond 6 inches as needed
• Locking stacking mechanism reduces dangerous lateral movement
• Maintains rated strength even when multiple pads are used
• Ideal for leveling on irregular or sloped campsites

What weather and wear protections does the pad offer?

The KIKIRV pad uses a high-performance polymer that resists common outdoor stressors so it stays functional and looks good season after season. Drainage holes prevent water pooling, while the material resists stains and UV degradation to minimize damage from sun and elements.

• UV-, oil-, water-, heat-, and stain-resistant polymer construction
• Drainage holes stop standing water and reduce freeze/thaw damage
• Material hides minor stains for a cleaner appearance over time
• Designed to withstand repeated outdoor exposure without cracking

How easy is it to carry, position, and store this jack block?

The pad includes integrated side holes and ships with a rope for carrying, lifting, and anchoring. Its one-piece build is compact for trunk or compartment storage and the durable polymer survives being tossed in gear piles.

• Built-in side holes and supplied rope for convenient transport
• Lightweight relative to capacity, easy to place under jacks
• Compact shape stacks flat for tidy storage in RV bays
• Drainage and durable finish reduce maintenance needs

Who is this for? If you tow or camp with a trailer, fifth wheel, or RV and need a reliable way to prevent jack sinking and wobble on soft or uneven terrain, this KIKIRV 6" Trailer Jack Block is a practical choice. It suits RV owners, weekend campers, landscapers, contractors, and anyone needing a compact, strong pad for tongue jacks, wheel jacks, scissor stabilizers, or hydraulic 5th wheel jacks. The weather-resistant construction and stackable safety features make it a dependable accessory for seasonal travel and year-round storage.
