Stable, ready-to-travel trailer leveling with TOWKING

Meet the TOWKING 4-pack Trailer Jack Blocks, upgraded for dependable leveling on a variety of terrains.

With a combined 12,000 lb capacity, these blocks are designed to support heavy trailers and RVs as you park, level, and prepare for your next leg of the journey. This is a complete kit built with travel in mind, so you can focus on the trip, not the setup.

Universal fit that covers most rigs

The 10-inch platform with a 2.5-inch hole is designed to fit a wide range of jack feet, including tongue jacks, wheel jacks, scissor jacks, and many fifth-wheel configurations. You won’t have to scramble for a different block to match your setup.

• Heavy-duty 12,000 lb capacity for solid support
• UV-shielded polypropylene resists sun and weathering
• Universal 10" platform fits most jack feet

Built to handle uneven surfaces

The anti-tilt design combines a cone base with eight ribs to minimize wobble in mud, gravel, or sloped ground. The result is a more predictable, stable platform as you level and secure your trailer.

• Cone base with eight ribs reduces wobble
• Design supports stable positioning on challenging terrain

Smart, secure stacking for quick adjustments

Height adjusts from 6 inches to 8.6 inches in seconds, with a locked stacking system to prevent shifts during setup or packing. Drain holes help shed water, and an ergonomic grip makes handling easier, whether you’re at dawn or dusk.

• Height adjustable from 6" to 8.6"
