Salahii 6" Trailer Jack Block 6-inch Stackable HDPE 40,000 lb Capacity, UV‑Resistant Stabilizer

Salahii's 6" Height Trailer Jack Block is a heavy-duty, stackable HDPE leveling and stabilizing block engineered to support up to 40,000 lbs for RVs, trailers, and campers.

Whether you're parking on gravel, a slope, or soft ground, the Salahii jack block gives your tongue jack, scissor jack, or stabilizer a dependable platform. Built from injection-molded high-density polyethylene (HDPE) with UV and water resistance, each 6-inch unit locks securely when stacked and includes handles and drainage to simplify transport and storage. The design reduces wobble, spreads load, and helps keep jacks from sinking into unstable surfaces.

How much weight can each Salahii leveling block carry?

Each block is tested to handle substantial loads—up to 40,000 pounds—making them suitable for most travel trailers, fifth wheels, and large campers when used as intended. The injection-molded HDPE construction delivers consistent strength across repeated use.

• Rated support: up to 40,000 lbs per block
• Engineered injection-molded HDPE material for load consistency
• Stackable locking design preserves bearing capacity when combined
• Stable base reduces point pressure on soft surfaces

Will these blocks work with my trailer’s jack or stabilizer?

Yes—Salahii blocks are made for universal compatibility. They fit tongue jacks, wheel jacks, scissor jacks, post feet, and stabilizers, providing a solid platform that minimizes wobble and improves safety when parked on uneven ground.

• Universal fit for most jack foot types and stabilizers
• Flat top surface supports various jack pad shapes securely
• Locking stack mechanism prevents shifting under load
• Non-slip contours help keep jacks centered

How do the stackable features and portability help on the road?

Each block measures 6 inches high and locks with the next unit, so you can quickly build the height you need without sacrificing stability. Built-in side handles and rope-ready holes make carrying and stowing easier, while center drainage stops water pooling during storage.

• 6" height per block for predictable increments
• Interlocking edges prevent wobble when stacked
• Side handles and rope holes for easy transport
• Drainage holes eliminate standing water for tidy storage

What weather and wear should I expect from these HDPE blocks?

Salahii designed these stabilizer blocks for outdoor use; the HDPE resists UV degradation, water absorption, and common road abrasion. They remain dimensionally stable across seasons, so you can rely on them for long-term trips and repeated setups.

• UV-resistant HDPE preserves strength and color
• Water-resistant surface avoids swelling or softening
• Injection-molded build reduces cracking under stress
• Easy to rinse clean after muddy or sandy use
