Features

  • 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.

  • Works great
Size: Single
Very heavy-duty and works well on my toy hauler definitely sturdy and well built

  • Sturdy and dependable!
Size: Single
Great product! Have used this for a few years now on several different trailers. Very sturdy and good weight. I do recommend covering finger holes on sides with duct tape or will get critters in there!

  • Solid and sturdy
Size: Single
I love this. I use it with my horse trailer which has a weird foot and we hook up different truck to it. It’s always the right height, short enough it fits under the foot even with the smaller trucks but tall enough I can jack up the trailer for my bigger trucks. It’s heavy duty, solid, versatile and survives all the weather. ... show more

  • They work great
Size: 5-Pack
These are simple, but they're well made, heavy duty, and they do the job. I'd recommend them.

  • Last BLOX you'll ever NEED!! Last BLOX you'll ever NEED!!
Size: Single
These things are incredible!! Originally purchased more than a year and a half ago to hold a HUGE destination trailer. These things show ZERO wear and seem as though they're virtually indestructible to the elements. Despite needing 5 for my setup it provides unparalleled stability and makes the unit feel as solid as the ground it sits upon. Worth EVERY penny!! Couldn't be more proud that this level of superiority is MADE IN THE USA!! ... show more

  • No More Splinters
Size: Single
Lightweight but strong and durable. Had been using a big wood block - not only heavy but splinters at times. This is a great replacement - well worth the price.

  • Sturdy
Size: Single
These are very thick and sturdy. Stack well. If you’re using them on a fifth wheel with a round platform on the end of the leveler, you need to take that off and just use the pole itself. I wish it would accommodate the round platform at the end of the leveler instead of having to take that off

  • OX BLOX are Wonderful
Size: 4-Pack
These are GREAT! They hold the stabilizer jack firmly in place - no more guessing with a stack of 2x4s. I would highly recommend them.
