RELIANCER Wheel Chocks 2-Pack Extra-Large Rubber Chock Blocks — Heavy-Duty with Handle & Reflective Stripes

RELIANCER heavy-duty rubber wheel chocks are a pair of reinforced natural rubber blocks designed to hold wheels securely for trucks, RVs, trailers and commercial vehicles.

These extra-large chocks (10" x 6" x 7.3", 6.8 lb each) combine dense, UV- and oil-resistant rubber with a textured, curved face and built-in handle to make placement fast and reliable on driveways, ramps or outdoor job sites. They were engineered to resist compression, moisture and extreme temperatures while offering improved friction versus typical plastic blocks. Three bright reflective stripes increase visibility in low light so you can see where the chock is placed day or night.

How do these chocks keep a vehicle from rolling?

The RELIANCER rubber chocks use a curved, textured contact surface that nests against a tire, increasing the contact area and friction. Their weight and non-slip rubber base resist lateral movement, while the material's compression resistance helps them maintain shape under heavy loads. Together these features reduce the chance of wheel creep on slopes or during maintenance.

• Curved face conforms to tire profile for maximum contact.
• Textured surface increases grip on rubber and metal rims.
• Heavy 6.8 lb each weight keeps chocks in place under load.
• Non-slip oil-resistant bottom grips most surfaces including concrete and asphalt.

Are these chocks durable enough for commercial use?

Yes — constructed from reinforced natural rubber, they resist UV, oils, moisture and temperature swings that can degrade cheaper materials. The rubber formulation offers strong compression resistance so the blocks retain their shape under repeated heavy use. They outperform many plastic chocks and avoid the brittleness of low-grade compounds.

• Reinforced natural rubber resists wear and environmental damage.
• Designed to handle heavy-duty loads from trucks, haulers and fire vehicles.
• Light rubber scent indicates solid material rather than harsh chemicals.
• Curved, textured face resists flattening from repeated pressure.

How does the design help with visibility and placement?

Each chock has a molded handle for fast positioning and removal without stooping or wrestling with the block. Three bright reflective stripes on the top surface reflect headlights and flashlights, making the chocks easier to find and less likely to be overlooked in dim conditions. The handle also improves safety when placing chocks on steep inclines or around heavy equipment.

• Built-in rubber handle for quick, ergonomic placement and retrieval.
• Three reflective stripes visible from multiple angles day or night.
• Handle reduces hand contact with potentially oily surfaces.
• Curved top and sides allow secure handhold and storage stacking.

What surfaces and vehicles are these chocks best for?

These extra-large chocks are suitable for a wide range of vehicles and surfaces — from personal RVs and SUVs to heavy commercial trucks and trailers. The non-slip oil-resistant bottom makes them effective on concrete, asphalt and packed dirt. Their size and weight balance portability with staying power, making them preferable to lightweight plastic or awkward concrete alternatives.

• Works with cars, trucks, SUVs, RVs, trailers, hauler and fire vehicles.
• Effective on driveways, garages, service ramps and campground pads.
• Heavier than plastic, lighter than concrete—portable yet stable.
• Sold as a set of two for front-and-rear or dual-wheel security.

Who is this for: The RELIANCER 2 Pack wheel chocks are aimed at vehicle owners, mechanics and fleet operators who need reliable, reusable wheel restraint that stands up to frequent use and outdoor conditions. They suit RV owners, commercial drivers, auto shops and anyone who uses ramps or works under vehicles and wants a robust, visible safety accessory that’s quick to deploy.
