LEORAY Jack Wheel Chock Dual-Wheel Reinforced Rubber Dock — Nitrile, Drainage

LEORAY's Jack Wheel Chock is a one-piece reinforced rubber dock designed to stabilize dual jack wheels, stop rolling or sinking, and protect trailer jacks on soft or uneven ground.

When you're parking a caravan, trailer, or camper, the jack wheel is a small but critical component that must remain steady and intact. This reinforced dual-wheel chock from LEORAY spreads load, resists oil and water, and keeps the jack wheel from digging into mud, sand, or soft soil. Built from heavy-duty nitrile rubber with molded drainage, it offers a compact, long-lasting solution that stores easily in your vehicle.

How does this chock prevent the jack wheel from sinking or rolling?

The chock creates a broader, stable surface beneath the jack wheel so weight is distributed across the rubber body rather than concentrated on soft ground. Its shape resists lateral movement and the dual-wheel groove holds the caster securely to reduce rolling.

• Wide base disperses downward force to reduce ground penetration.
• Dual-wheel recess keeps wheels centered and blocks sideways slip.
• Molded rubber offers grip on gravel, grass, and packed dirt.

What materials and features extend the jack wheel’s service life?

Constructed from premium nitrile rubber in a single molded piece, the chock resists oil, gasoline, water, and some hydraulic fluids that would otherwise degrade metal and bearings. Built-in drainage channels prevent standing water, limiting corrosion risk and keeping the wheel cleaner.

• Nitrile rubber formulation resists common automotive fluids and weathering.
• Drain holes prevent water accumulation and reduce rust exposure.
• Vulcanized finish is odorless and withstands wide temperature ranges.

How easy is it to store and use this jack wheel dock?

The compact dimensions (about 7 in × 6.7 in × 1.38 in) make the chock light and simple to carry, slip into a trunk, or stash in an onboard locker. Its single-piece construction means there’s no assembly required—simply position it under the jack wheel and lower the jack as normal.

• Portable dimensions fit most vehicle storage compartments.
• Single-mold design eliminates loose parts and simplifies use.
• Non-toxic and odor-free thanks to high-temperature vulcanization.

Is this chock durable enough for regular outdoor use?

Yes—the heavy-duty build and chemical-resistant rubber are made to withstand repeated exposure to outdoor elements and common vehicle fluids. It’s intended for long-term use and to protect the jack wheel from contaminants that shorten service life.

• One-piece molded construction resists tearing and deformation.
• Formulation tolerates gasoline, oil, and propane exposure.
• Designed to endure repeated mounting, storage, and temperature changes.

Who is this for: The LEORAY Jack Wheel Chock is suited to caravan and trailer owners, motorhome travelers, tow vehicle technicians, and anyone who parks on soft or uneven terrain and wants a compact, durable way to protect jack casters. If you need a low-effort, long-lasting dock that prevents sinking and limits wear from dirt and fluids, this product is designed to fit into routine caravan maintenance and travel preparations.
