OULEME Trailer Jack Blocks 2PCS - Heavy Duty Recycled Plastic, Fits 2" Tongue Post & 9" Round Feet, 15,000 lb Capacity

OULEME Heavy Duty Trailer Jack Block 2PCS are durable recycled-plastic support pads designed to stabilize trailer jacks, tongue posts and scissor stabilizers, each rated to hold up to 15,000 pounds.

If you tow or park an RV, camper, travel trailer or 5th wheel, a reliable jack block prevents sinking, reduces wear and creates a stable base for loading, leveling and storage. OULEME's blocks are molded from dense recycled plastic, built with a grooved top for stacking stability, a recessed post hole with a reinforced iron plate, and dimensions that fit common round and square jack feet, tongue posts and jack wheels.

What types of trailer jacks and feet will these blocks work with?

These jack blocks accommodate a wide range of contact points on trailers and RVs. They accept square jack feet, round jack feet up to 9 inches, 2-inch tongue jack posts and typical 6x2 inch tongue jack wheels. The recessed hole and iron plate improve grip and wear resistance for metal posts.

• Fits round jack foot diameters up to 9"
• Compatible with 2" tongue jack posts and 6x2" jack wheels
• Works with scissor stabilizers and standard square-foot jacks
• Reinforced post hole prevents sliding and reduces wear

How stable and strong are these blocks under load?

Each OULEME block is engineered to support heavy loads—up to 15,000 pounds per block—thanks to increased wall thickness and higher-density recycled plastic. The grooved top surface helps blocks lock together when stacked, improving lateral stability during use.

• Single-block height: 6.3"; double-stacked height: 11.1"
• Bottom footprint: 11.2" x 8.8" for broad load distribution
• Grooved top for secure stacking and reduced shifting
• Iron-reinforced post hole for extra durability under metal posts

How do I use these blocks for leveling and storage?

Place the block beneath the jack foot, tongue post or jack wheel so the weight spreads across the wide base. For extra lift, stack two blocks with grooves aligned; use the recessed post hole to center posts and prevent slipping. Remove blocks carefully under load only if safe to do so and follow manufacturer jack-safety guidelines.

• Set block on firm, level ground beneath jack contact point
• Stack two blocks with grooves aligned to reach 11.1" height
• Center jack post in recessed hole for secure engagement
• Use blocks for parking, storage, stabilization or tire/axle work

Will these blocks resist weather and wear over time?

The blocks are molded from recycled plastic formulated for heavier sections and increased density, which helps resist cracking, moisture absorption and rot compared with wood. The iron plate in the post hole reduces metal-on-plastic abrasion and extends service life where metal posts bear down.

• Recycled plastic resists water and decay better than wood
• Thicker walls reduce stress points and deformation
• Iron plate protects the post-contact area from wear
• UV and cold resistance depend on exposure—store when possible

Who is this for: OULEME Heavy Duty Trailer Jack Blocks are a practical choice for RV owners, tow operators, campsite hosts and anyone who needs a reliable, reusable support under trailer jacks or stabilizers. They suit occasional campers who want a dependable base and professional haulers who need rugged, stackable pads that stand up to heavy loads and repeated use.
