OX BLOX Heavy Duty Trailer Jack Block - 10,000 lb Capacity - Made in USA
- Strongest Trailer Jack Block on the Market: Rated up to 10,000 lbs per block, OX BLOX are built to handle tongue jacks, post jacks, foot jacks, scissor jacks, and stabilizer jacks — round or square. Use as a trailer jack stand, RV leveling block, or stabilizer pad for travel trailers, 5th wheels, boat trailers, horse trailers, and more.
- Stable on Any Surface: The patented design (US 11,673,440 B2) keeps your trailer stable on gravel, grass, dirt, and pavement. Engineered by Utah-based designers to eliminate wobble and sway, these RV jack blocks give you rock-solid support whether you are at a campsite, on a job site, or parked in your driveway.
- Stackable for Extra Height: Stack multiple OX BLOX on top of each other for added lift — rated to 10,000 lbs even when stacked. Works as a camper leveling block, tongue jack block, or hitch block to get your RV perfectly level on uneven ground.
- Made in the USA from Recycled Plastic: Compression-molded from 100% recycled plastic right here in America. UV and temperature resistant — built to last through years of camping trips, seasonal storage, and harsh weather without cracking or degrading.
- Easy to Carry: Grab handles on each side make these RV stabilizer blocks easy to move around your rig. At just over 8 lbs each, they take up minimal storage space in your camper or truck bed. OX BLOX camper blocks for jacks are the last trailer jack pads you will ever need to buy.
