HOXWELL RV Trailer Jack Block 8" High — Stackable Orange Stabilizer, 12x12 Base & Handle

HOXWELL's 8" high RV trailer jack block is a stackable, portable support block that gives your tongue jack, post or stabilizer a wide, crush‑resistant base for safer, steadier parking.

When you park on soft ground, uneven campsites, or gravel, a flimsy jack foot can sink or shift — causing wobble and frustration. The HOXWELL jack block is engineered to withstand heavy loads up to a GVW of 40,000 lb (18 tons) while providing a broad, stable surface. Its compact 12 x 12 x 8 inch footprint, built‑in drainage, and lightweight handle make it easy to carry, stack, and nest for storage, so it’s ready whenever you need dependable leveling or extra support at the campsite.

How does this block make my trailer more stable?

The HOXWELL jack block spreads the load across a larger area than a jack foot alone, reducing pressure on soft soil and preventing sinking or tilting. Its reinforced internal structure resists cracking under heavy weight so the jack remains firm under load.

• 12 x 12 inch base increases contact area for better load distribution
• Reinforced interior structure resists deformation under heavy GVW
• Works with tongue jacks, square/round posts, and scissor stabilizers

Can I change the height or stack them for uneven ground?

Yes — the blocks are designed to stack securely so you can build the height you need without sacrificing stability. When not stacked, they nest together to save storage space and stay tidy in your gear closet.

• Stackable design for custom height adjustments
• Nesting shape conserves space when stored
• Each block adds 8 inches of height; combine as needed for level setup

Is it easy to carry and keep dry in wet conditions?

At about 2.87 lbs the HOXWELL block is light enough to carry with the integrated handle and rope, simplifying transport and placement. A built‑in weep hole allows drainage so water and debris don’t pool inside, preserving the block’s integrity and reducing freeze damage or trapped mud.

• Lightweight 2.87 lb construction with convenient handle
• Drainage weep hole prevents water buildup and debris collection
• Durable exterior resists cracking in grass, gravel, or mud

What size vehicles and jacks will this block support?

The block’s broad base and heavy‑duty build are suitable for most RVs, trailers, campers, and utility equipment jacks. It was designed to accommodate a wide range of tongue jacks, posts, feet, and scissor stabilizers so you can rely on it across different rigs.

• Compatible with tongue jacks, round or square posts, and scissor stabilizers
• Rated for vehicle gross weights up to 40,000 lb (18 tons)
• Measures 12 x 12 x 8 in to fit common jack foot sizes

Who is this for: The HOXWELL 8" jack block is aimed at RV owners, trailer haulers, and campers who need a lightweight, durable solution to prevent jack sinking and movement on uneven or soft surfaces. It’s also useful for service technicians and outdoor enthusiasts who require portable, stackable support that packs away neatly and performs reliably under heavy loads.
