🔧 Ultra-Fab Products 48-979004 Ultra Stacker Jacks: Efficient and Reliable Stabilizing Solution Review

Used them to reduce the movement of my toy truck. Pretty cheap and if your RV is big at all I would recommend jacking it up on wooden blocks.

I used them to lower the subframe on our car to replace the rack and pinion. They are cheap, light weight and perfect for what I used them for.

I've stabilized my 36ft Lacrosse and these khakis are so easy to set up, even in tight spaces. An unstable RV can make you sick, try these extremely easy to use and easy to store.

I ordered them because I decided I didn't need trailer supports at the moment. They are simple, fast and easy to use. You won't beat her for money.

Due to the position of the support legs, I found it difficult to lower them. Got these four packs of coasters and love them. Lightweight and supports the back of the camper without any problem.

You get what you pay for. They are cheap and not designed for weight. An elongated propeller deforms and wobbles under weight and does not provide a solid surface.

Purchased for our 34ft Jacko standing on solid ground. I put a concrete block under it so that the height is sufficient. Our Jaco is brand new. It only has rails that are about an inch and a half long. I. Sure how it happened but they seemed to fall off and work loose and held our trailer in place for a couple of weeks. They have been replaced with cinder blocks.

I've been looking for the biggest and tallest fork lift for a long time and thought I found it. The listing says "Product Dimensions 12.2" x 7" x 6.8". Not even close. You have to be talking about the box it came in because the real jack (not including the screw that goes up) is 9 inches high and 6 inches on each side at the base. I'd love to send them back but can't find anything else so I'll get them working. Of course it can be extended to about 16 inches with an adjustable large bolt…
