2-pack plastic spacer blocks for heavy loads Key benefits Reliable support: Designed to carry heavy loads so your jacks, stabilizers, and supports sit on a solid base rather than digging into soft ground or damaging surfaces. Load distribution: Increases contact area to spread weight evenly and reduce pressure points on vehicle frames, trailer jacks, and support stands. Durable, low-maintenance material: Made from quality plastic that resists cracking and requires no painting or regular upkeep. Compact and easy to use: Lightweight to carry and simple to position where extra clearance or a stable footing is needed. What this solves Prevents sinking and instability on soft or uneven surfaces. Protects vehicle and equipment surfaces from direct metal-to-ground contact. Adds safe, predictable clearance when precise height or spacing is required. Important attributes Quantity: 2-pack — buy two blocks together for paired jacks or supports. Material: Quality plastic — engineered for durability under heavy loads. Function: Acts as a spacer, base pad, or support block to improve stability and distribute weight. Compatibility: Ideal for recreational vehicles and trucks and suitable for other heavy-load applications where a stable, non-marring spacer or base is needed. Typical use scenarios RV stabilizer pads: Place one under each stabilizer jack to increase footprint and prevent jacks from sinking into gravel, grass, or soft ground. Truck jack or support base: Use as a footing under a truck jack or axle stand to protect the ground and the jack base while improving stability during maintenance. Cargo or equipment spacing: Use as a spacer or protective block when stacking or securing heavy equipment to prevent metal-to-metal contact and to maintain necessary clearance. How to use Position the block under the jack foot, stabilizer, or contact point. Ensure the block sits flat and fully supports the load surface before applying weight. Use both blocks where paired support is required or keep a spare for multiple points of contact. Why choose this product Straightforward, practical solution for improving stability and protection in RV, truck, and other heavy-load applications. Two blocks provide immediate paired support or a spare for replacement when needed. No special tools required; ready to use out of the package.
