Dnigh Trailer Jack Block 4.7" High — Heavy‑Duty 35,000 lb Rubber Leveling Block, Non‑Slip Stackable

When you park an RV, camper, or trailer, a reliable base under the jack or stabilizer prevents sinking, rocking, and premature wear. The Dnigh Trailer Jack Block uses a reinforced, high-density rubber compound to resist compression and environmental wear while a patterned base keeps the block firmly in place on dirt, gravel, and pavement. These blocks are portable, stackable for extra height, and compatible with most scissor and tongue jacks as well as stabilizer pads.

How does the Dnigh block improve stability while parked?

By increasing contact area and resisting deformation, the block reduces trailer movement and the transfer of load into the jack foot. That steadier foundation means less rocking when people move inside the trailer and less constant stress on the jack hardware.

• Up to 35,000 lb rated capacity for heavy trailers
• High-density rubber compound resists cracking under compressive load
• Reinforced non-slip base keeps the block from shifting
• Reduces rocking and jack wear by distributing weight evenly

Will these work with my scissor or tongue jack?

Yes — the Dnigh jack blocks are designed for broad compatibility with common trailer support systems. Their tapered or flat top surfaces accept a variety of jack feet and stabilizer pads without the need for adapters.

• Fits scissor jacks, tongue jacks and many leveling pads
• Stackable design for adjustable height (do not stack more than two)
• Works as a single solution to reduce the need for multiple block types
• Also usable as a seat or step-stool when stacked (limited to two)

How do I use and maintain these jack blocks?

No assembly or tools are required — place the block under the jack foot or stabilizer and lower until the weight is supported. Clean with water and mild detergent as needed; the rubber compound resists dirt, oil, and outdoor exposure so upkeep is minimal.

• Simple drop-in use—no installation steps required
• Wipe or hose off mud and grime; air-dry before storage
• Inspect for deep gouges or deformation before heavy use
• Follow stacking guidance: maximum two blocks high for safety

What load and safety features should I expect?

These blocks are engineered to handle heavy static loads and to limit movement under normal campsite activities. The reinforced base and compression-resistant material are intended to keep the jack stable and reduce slippage on uneven surfaces.

• Rated to support up to 35,000 lbs in static load scenarios
• Non-slip patterned base resists lateral shifting
• Compression-resistant HD rubber helps avoid flattening under load
• Using multiple blocks under several stabilizers improves overall stability

Who is this for: The Dnigh 4.7" Trailer Jack Block is aimed at RV owners, trailer haulers, and weekend campers who want a durable, portable foundation for jacks and stabilizers. It’s a practical choice for anyone who needs a rugged, reusable block that reduces rocking, protects jack hardware, and works across a range of equipment without adapters.
