Camper Jacks with stackers for stable leveling

Stackers lock together and their bottoms grab the ground, so setup is quick and easy under jacks or under your wheels. With 40,000 lbs capacity and use on black top or softer ground, they suit hydraulic jacks and large, heavy trailers; just support each wheel and avoid deep ruts or steep inclines to prevent uneven stress.
Yes, they can be used under hydraulic jacks to spread the load and help prevent sinking. They have a 40,000 lbs capacity. On hot asphalt or softer ground, stack more blocks or widen the footprint to distribute weight. Avoid placing them over a deep rut or on a steep incline.
Yes, they work under jacks/stabilizers and under wheels for leveling. Make sure each wheel is supported to reduce stress on an axle. With large or dually tires you may need extra blocks and may need to place some side by side to get the width and height you want.
Each block adds 1-3/8 inches of lift. Stack as needed to reach height, keeping all wheels supported on the ground or on blocks to avoid uneven stress. If you build a ramp, place blocks under the other wheel on that axle too so weight isn't concentrated on one side.
A single block may not be wide enough for some jack feet, so plan on using two side by side when needed. In sandy or muddy spots, using a base under the blocks can help keep them from sinking. If you see any pin or block deformation, spread the load with more blocks.
