Trailer Jack Block, Premium Camper Jack Block Supports up to 15,000 LBS, RV Stabilizer Blocks Universal Compatibility for Tongue Jacks, Posts, Feet, or Scissor Stabilizer with Easy Carry Handle

These things are tough and very solidly stackable.

I purchased this to put under my tongue jack. Like my fathers before me, I used a wooden block for a very long time. At least until I left that wooden block somewhere along the way. Since I didn't feel like going out and getting a new wooden block, I found this bad boy on Amazon instead. It's incredibly sturdy, well made, and holds my trailer up in front very well.

I don't know why it took me so long to get one of these.... great purchase, seems well-made and sturdy..

I've been using a 6x6x12 for years, but this is a better solution. It seems more secure, while being a bit lighter.

I purchased this block to replace the 4"x6" chunk of wood! After buying other jack stands before, I was expecting some plastic junk that may last a dozen uses. My trailer has a gross weight of 6,000LBS. It's not a small weekend worrier trailer.I was pleasantly surprised to see how well constructed and heavy duty this block is.. It is heavier than the chunk of wood!The side walls (where they typically fail) is close to 3/8" thick and has cross walls through out the block.I put under my jack stand yesterday with the trailer full of debris. I need a block under my jack stand as my truck sits high and I need a block to unhitch the trailer. The block fit well under the jack. Holds the base well. The block did not have any flex in it at all. As a matter of fact, the block pressed into the asphalt but did not flex!Impressed. Fits well in the trailer box.Great find at a very reasonable price.

Well-made and very heavy duty. My only downside is the price. But this thing is a beast.

This thing is a beast. It's heavier than I thought it would be, but not so much that it's too heavy to move easily. It's just not a plastic bucket. As you can see from the pics it has a nice metal weight distribution plate and very good webbing on the back to make this a sturdy device. I've been using 2x4 or 4x4 to lift the front of the trailer higher than the jack goes to help keep water out or to help dump dirt out of the trailer. This jack block is much better than those wood boards. It also will keep the jack from moving at all since it holds the wheel in place. I am using this on a small jetski trailer and a utility trailer, but I'd have no problem using this on an RV or larger trailer - it's very heavy duty.

I like these sooooo much better than wood blocks. They stay cleaner, lighter, and you can stack them. They easily hold the weight of my trailer. I tested the tongue weight at 1000 lbs and it sits very solid on this block. This is an incredible buy and something you will use constantly with your travel trailer. Everyone needs to get at least one of these. I would encourage to get 2 or 3 so you can stack when needed or use for the stabilizers.
