🏋️ Ultra-Fab Products 48-979003: The Ultimate Stacker Jacks for Superior Stability Review

Looks solid and well made. They stack neatly (you have to take one of the nuts/bolts out of one to stack them inside each other). The price is worth it.

They are easy to use and well made. But there's no way they can safely hold 6,000 pounds. If you only need about 1000 pounds of buoyancy, they are perfect.

We use them to stabilize our little front popup. They help you move and push less. They seem to be holding up well, time will tell.

Used this type of jack many times, these strong suction cups eliminate movement more than the pre-installed ones damaged by reversing on hilly terrain. Easy to use, smooth operation.

Used these jacks to stabilize our RV. Doesn't matter! Now I can sleep when someone walks around the RV. So easy, place them under the frame and that's all you have to do.

I needed a pair of these for my camper trailer. They were more expensive at auto parts stores. But I bought them here hoping they will last. I've used them many times and they work great. They are very durable and of high quality.

I used them to hold and lower the rear axle on my truck to fit larger leaf springs. I then used one to hold the pressure on the lower control arm and knock out the ball joint. The stand collapsed. I think it's pot metal. 😬

They're stronger than they look. They look pretty flimsy when I got them but they seem to work fine. I've seen the same shelves in local stores for more than double the price. I confess I don't use them for anything heavy. I use them with a 5ft x 8ft aluminum frame cargo trailer that I converted into a square RV. Be sure to put a piece of wood underneath to keep them from sinking into the ground and place a piece of wood between the trailer frames. and a kickstand, because with metal on metal…
