MaxxHaul camper jack blocks provide strong, stable support for your RV or trailer. Made from sun-resistant plastic that resists dirt and oil, they won’t crack or deform even after heavy use. Each block weighs just 4.62 lbs, and is easy to carry with side handles or the built-in rope loop. Designed to hold up to 10,000 lbs, the textured anti-slip surface and recessed post holes keep your jack secure, while the reinforced base prevents rocking or sinking. A built-in drain hole helps channel away water and debris to protect your jack from rust, making it ideal for all-weather use. Measuring 11.5" × 11.5" ×6", these blocks fit most scissor jacks, tongue jacks, posts, feet, and stabilizers—an essential accessory for safer, steadier camping trips.
