TOWKING Trailer Jack Block 6" Stackable Camper Leveling Block 12,000 lb Capacity, Anti-Tilt 10" Platform

TOWKING's 6" stackable trailer jack block is a heavy-duty, anti-tilt support pad that raises and stabilizes trailer jacks up to 12,000 lbs while stacking securely for adjustable height.

When hitching, leveling, or parking a camper or trailer, a compact, durable jack block reduces wobble, prevents sinking on soft ground, and speeds setup. The TOWKING 6" block features a 10" platform with a 2.5" center hole to accept most jack feet, a reinforced cone base with ribs for anti-tilt stability, and a locking stack design so you can safely add height without slipping. Built for road use, the unit includes drainage ports, ergonomic grips, and travel storage so it’s ready for outdoor conditions and frequent handling.

How does this jack block stop jacks from tilting on soft ground?

The block’s cone-shaped base plus eight reinforcing ribs spread weight across a broader footprint and penetrate softer surfaces for grip. This geometry reduces lateral movement and prevents the jack foot from sinking or rocking under load.

• Anti-tilt cone and ribs for secure contact on mud, gravel, and grass
• Wide 10" platform to distribute pressure and reduce sinkage
• Drain holes prevent water buildup that can soften surfaces

What sizes and weights can it support, and will it fit my jack?

Each block is rated to support up to 12,000 lbs, suitable for most trailer tongue and scissor jacks as well as fifth-wheel components. The 2.5" center hole fits common jack foot sizes, and the large platform accommodates a wide variety of shapes.

• 12,000 lb rated load capacity per block
• 10" platform diameter with 2.5" center hole fits standard jack feet
• Compatible with tongue jacks, wheel jacks, scissor jacks, and more

How do stacking and locking work for adjustable height?

The blocks interlock with a keyed design so you can stack units quickly and securely without slippage. A single block provides 6" of lift; stacking a second unit increases height to approximately 8.6" for additional clearance when needed.

• Smart interlocking profile prevents dangerous lateral shifts
• Stack from 6" to 8.6" in seconds for flexible height options
• Quick-strap and storage bag included for transport and organization

What convenience features make this travel-ready?

The design includes user-focused details to make regular use easier and neater on the road. Drainage holes stop puddling, ergonomic grips simplify handling even when dirty, and a 600D carry bag plus quick-strap keep the system compact and secured during transit.

• Drain holes prevent water collection and freeze damage
• Ergonomic grips for easy carrying and positioning with gloves
• 600D storage bag and quick-strap secure blocks while traveling
