TOWKING Trailer Jack Block 6" Stackable 12,000 lb Support Pad — 10" Top, Interlocking Stability

Whether you’re setting up camp on gravel, dirt, or soft turf, this rugged jack block gives a wide, non-wobble platform for trailer jack feet, tongue jacks, scissor jacks and fifth wheel landing gear. Built to be lightweight to carry yet strong enough for demanding loads, it replaces flimsy wood or small pads and is designed to stack securely when extra height is needed. The packable system includes engineered features that help keep gear dry, positioned and easy to use on the road.

How does this block improve jack stability on soft or uneven surfaces?

The block’s cone-shaped base with multiple ribs increases ground contact and resists sinking or tipping, so the jack foot stays centered under load. The wider platform spreads pressure to reduce ground penetration and minimize wobble under weight.

• 12,000 lb rated platform for substantial loads
• Conical base plus eight ribs for firm ground grip
• 10-inch top platform to distribute pressure evenly
• Drain holes to prevent water pooling and rot-free performance

Can I stack blocks to gain more height, and is stacking secure?

Yes — the pieces are designed to interlock so you can safely increase jack height without slippage. A locking profile keeps stacked blocks aligned and prevents shifting when the jack is under tension.

• Interlocking geometry for fast, stable stacking
• Increase height from 6" to roughly 8.6" per the design
• Locking ribs reduce dangerous lateral movement
• Handles and strap points make assembly fast and sure

What sizes and jack types will fit this pad?

The large 10-inch top surface and 2.5-inch central hole accommodate most common jack feet and tongues, including scissor, wheel, tongue and fifth-wheel jacks. Its universal sizing avoids the need for multiple pad types in your kit.

• 10" platform fits standard and oversized jack feet
• 2.5" center hole for secure jack insertion
• Works with tongue jacks, scissor jacks and landing gear
• Compact enough to store in included travel bag

What travel and convenience features come with the block?

The set was designed for road use: ergonomic grips, drain holes and a durable carrying bag simplify transport and handling. A quick-strap option helps keep stacked units together during storage and transit.

• Ergonomic grips for easy lifting and placement
• Drain holes to shed water and prevent freezing issues
• Includes 600D storage bag for organized transport
• Quick-strap compatible for secure packing
