Great jack putbon my dump trailer had a to screw type 5k and it couldn't do heavy loads like thus can I bent the previous jack handle trying to lift load. This has the power with leverage so makes heavier loads easier to take off truck. Just wish it had a bolt on plate option I weld but finding time to do it right is hard when you have kids and a buisness to run. Did weld on well and the outside stock is sized right for the job.

I got 2 of these for a trailer build. The jacks seem like every other jack that I've installed as far as quality and use. The foot release spring is strong and the pin engages positively. There is a grease fitting for maintenance. Neither of these jacks came with a handle, although the seller did respond quickly to my message and did send 1 handle to me. The handle delivery time was much longer than the jack delivery time. This was acceptable, because this build only needs 1 handle and I was far enough ahead on schedule, although this may not have satisfied every customer. I knocked off 1 star for this.

The jack itself has no issues but it came with missing hardware , all the hardware including the crank ( I would say that’s pretty essential in using the jack).Two weeks and 3 messages later, all that the seller had to say was that they can’t provide the missing hardware and asked me to return the weld on jack which I installed already.Now I have to spend the time to manufacture my own hardware. Avoid this seller .

Used on horse trailer to replace the one it came with because it was worn out. If I had known it would be that easy to replace and work so much better I would have done it a lot sooner.

I’ve bought four of these to convert two single jack gooseneck trailers. Are of equal quality to the other jacks which are OEM on these trailers. No problem welding jack tube to trailer. Crank rather easily. Delivered to my shop door
