OULEME Trailer Jack Block 15,000 lb RV Leveling Block — 8.5" Top Pad, Crush‑Resistant Polypropylene, Stackable 1-Pack

OULEME Trailer Jack Block is a heavy-duty 15,000 lb-rated leveling block designed to stabilize and lift RV jacks, tongue stands, scissor stabilizers and jack wheels for safer, easier camp setups.

Built from high-density polypropylene, this single-pack jack block provides a broad, non-slip platform that fits 8.5" jack pads and accommodates a wide range of trailer supports. It’s engineered to resist crushing and deformation under repeated use and stacks securely with interlocking grooves so you can tailor height on uneven ground. The compact footprint and strong load rating make it a practical addition to travel trailers, fifth wheels, and camper tongue jacks.

How does this jack block handle heavy trailer loads?

The OULEME block is rated to support up to 15,000 pounds per block and distributes weight across a stable 10" x 10" base to reduce ground sinking. High-density polypropylene construction adds strength while resisting cracking under pressure.

• 15,000 lb capacity per block for large trailers and fifth wheels
• 10" x 10" bottom for broad pressure distribution
• Crush-resistant polypropylene for long service life

Will it fit my jack, wheel or stabilizer?

This block accepts square jack feet and round jack feet up to 9" diameter, plus 2" tongue jack posts and common 6 x 2" jack wheels. The 8.5" top pad matches standard jack pads and accommodates scissor stabilizer feet without slipping.

• Top pad measures 8.5" to match standard jack pads
• Compatible with round feet up to 9", square feet, and scissor stabilizers
• Works with 2" tongue jack posts and 6 x 2" wheels

How do stacking and stability work on uneven ground?

Interlocking grooves and an anti-slip bottom let you stack two or more blocks securely to increase height while keeping the base steady on soft or sloped surfaces. Proper stacking raises the block height from 4.85" to about 8.2" for added clearance and leveling options.

• Interlocking design for secure multi-layer stacking
• Anti-slip base reduces sideways movement on loose soil or gravel
• Single height 4.85"; stacked height approximately 8.2"

How durable is the material in outdoor and travel use?

The block uses a dense polypropylene compound formulated to resist deformation, cracking, and UV-related degradation so it keeps its shape season after season. It’s designed to endure the repeated loading cycles of setup and travel without losing structural integrity.

• High-density polypropylene for weather and impact resistance
• Designed to resist crushing and retain shape under load
• Low-maintenance material that cleans easily after off-road use

Who this is for: The OULEME Trailer Jack Block suits RV owners, fifth-wheel drivers, and weekend campers who want a compact, high-capacity support that fits common jack pads and stabilizers. It’s a good match for those who need reliable, stackable leveling options for gravel, dirt, grass, or soft pavement and prefer a durable, low-maintenance solution for frequent setup and teardown.
