HOXWELL 8" RV Trailer Jack Block - 12x12x8 in Orange, Stackable & Handle for Stabilizing Jacks

HOXWELL 8" High RV Trailer Jack Block is a heavy-duty, stackable leveling and stabilizing base that gives your trailer jack, post, or stabilizer a durable, non-slip platform for secure parking.

When you park on soft soil, gravel, or uneven ground, the right jack base prevents sinking, swaying and instability. The HOXWELL jack block is engineered to carry large loads (up to a GVW of 40,000 lb when used correctly), drains water through a built-in weep hole, nests for compact storage, and includes a handle and rope for easy transport. Designed to work with tongue jacks, square and round posts, scissor stabilizers and feet, this single 12 x 12 x 8 inch orange block is a practical addition to any RV or trailer toolkit.

How does this block keep my trailer stable on soft or uneven ground?

The block distributes jack pressure across a larger surface area so jacks and stabilizers don’t sink or shift. Its reinforced internal structure resists cracking under heavy loads and the textured base increases grip on loose surfaces.

• Reinforced internal ribs for enhanced load-bearing strength.
• 12 x 12 inch footprint spreads weight to reduce sinking.
• Textured underside improves traction on gravel and grass.

Can I stack these blocks to reach the height I need?

Yes — the HOXWELL blocks stack securely to create custom height without losing lateral stability. They nest when stored to save space and remain stable when multiple blocks are aligned under a jack foot or stabilizer plate.

• Stackable geometry locks layers together for safe elevation.
• Nesting design reduces storage volume when not in use.
• Use multiple blocks to adapt to uneven campsite surfaces.

Will this block fit different jack types and resist weather damage?

The 8" block accepts round and square posts, tongue jacks, scissor stabilizers and other common foot types. A built-in weep hole prevents water accumulation, and durable molded material resists cracking and wear from outdoor exposure.

• Universal opening and flat top accommodate many jack shapes.
• Drainage hole prevents standing water and debris build-up.
• Durable molded polymer withstands dirt, moisture and repeated use.

How portable and user-friendly is this single-pack block?

At about 2.87 lb, the block is light enough to carry for campsite setups yet substantial enough to handle heavy loads. The integrated handle and attachment rope make transport, hanging or pulling into position quick and comfortable.

• 2.87 lb weight balances portability with performance.
• Built-in handle and rope for easier carrying and positioning.
• Also usable as a temporary camp seat when stacked or nested.

Who is this for: RV and trailer owners, weekend campers, contractors and anyone who regularly parks on unpredictable surfaces will benefit from the HOXWELL 8" jack block. It’s useful for single-axle trailers to large towables needing a reliable, transportable base under jacks or stabilizers. If you want a simple, stackable solution to prevent sinking, reduce sway and make campsite leveling faster, this block is built for that purpose.
