KIKIRV Trailer Jack Block 6" Height — 40,000 lb Stackable Stabilizer, Weather-Resistant

The KIKIRV 6" Trailer Jack Block is a stackable, weather-resistant polymer pad that stabilizes RVs, trailers, and jacks with a 40,000 lb load capacity per pad.

Designed for campers, travel trailers, fifth wheels and utility trailers, this 6-inch high jack block from KIKIRV provides a stable, non-slip platform for tongue jacks, scissor jacks, wheel jacks and hydraulic landing gear. Its high-performance polymer resists UV, oil, water and heat so it holds up outdoors; stackable locking features let you customize height while maintaining load-bearing strength. Built-in carrying holes and drainage channels make placement and storage easier on the road.

How does this block keep my trailer steady on uneven ground?

The KIKIRV block spreads jack pressure across a larger footprint and conforms slightly to irregular surfaces, reducing tilt and bounce. When stacked and locked, the pads resist shifting under load and minimize rocking from wind or movement inside the RV.

• 6" single-height pad expands to custom heights when stacked securely
• Large base disperses weight to prevent sinking into soft ground
• Locking stacking design reduces lateral movement between pads
• Drainage holes avoid water buildup that can soften ground contact

Are these blocks suitable for heavy-duty jacks and large RVs?

Yes — each pad is rated to support up to 40,000 pounds, making them appropriate for most tongue jacks, scissor jacks, and 5th wheel hydraulic gear used on large campers. The polymer construction maintains strength under sustained loads while resisting environmental wear.

• 40,000 lb load capacity per pad for heavy-duty use
• Compatible with a wide variety of jack foot patterns and sizes
• Polymer material resists cracking, oil, and UV degradation
• Maintains structural integrity when stacked for higher support

How easy is it to carry, stack, and store these stabilizer blocks?

KIKIRV engineered these blocks for on-the-road convenience: built-in side holes and included rope make lifting and positioning straightforward, while the blocks’ shape nests together for compact storage. The lightweight polymer is easier to manage than heavy metal plates, yet remains durable.

• Side carry holes and supplied rope simplify transport and placement
• Stackable design nests securely to save space in cargo areas
• Lightweight polymer is easier to handle than steel or wood alternatives
• Drainage slots and stain-resistant finish minimize maintenance

What maintenance or care does the pad require to last outdoors?

Maintenance is minimal: rinse off dirt with water and store stacked under a cover when not in use to prolong life. The polymer resists stains, oil, and sun damage, so routine cleaning and dry storage are usually sufficient.

• Rinse with water to remove mud and debris
• Store stacked indoors or under a tarp when possible
• Avoid prolonged contact with sharp objects that could puncture the surface
• Inspect before use to ensure stacking locks engage properly

Who is this for: The KIKIRV 6" Trailer Jack Block is ideal for RV owners, professional haulers, and weekend campers who need a reliable, portable support solution. It suits anyone towing larger trailers or parked on uneven or soft surfaces who wants improved stability without heavy metal plates or makeshift solutions. If you need a durable, weather-resistant pad that stacks securely and carries easily, this product offers a practical, long-lasting option for safer jack and stabilizer use.
