When you’re hauling serious weight, you need a jack that won’t flinch under pressure. This square direct-weld jack handles a 10,000 lb lift and 12,000 lb support capacity with a durable 1" jack screw that turns smoothly even under load. Twin thrust bearings make raising and lowering steady and controlled instead of a chore. Weld it to your frame once and you’ve got a setup that stays solid job after job.
Instead of spinning the handle forever to reach the ground, you just pull the side-mounted plunger pin and let the spring-return drop leg do the work. The leg adds 13-1/2" for a total adjustment of 25-3/4", so you can fine-tune height fast and get moving again. When it’s time to retract, the spring pulls the leg back automatically—no need to lift it by hand.
Soft ground, gravel, and uneven pads are no problem for the solid rectangular footplate that keeps this jack steady and prevents sinking. Both the outer 4" tube and 3-1/2" inner tube are built from heavy-gauge steel with a black painted finish for long-term durability. The thick weld areas and sturdy construction hold up to regular work use without flex or wobble.
Keeping your jack smooth is as easy as a quick shot of grease. The integrated grease zerk fitting lets you service the internal screw without teardown or disassembly, keeping corrosion and wear at bay. That means less downtime and smoother cranking every time you hook up.
Mounting is direct and secure thanks to the weld-on design. The plunger pin sits to the side for easy access even when space is tight. The matching sidewind handle (part # TJD-12000-HD) installs with the included hardware when you’re ready to complete the setup. With replacement parts available for the screw, gears, and return spring, this jack is made to stay serviceable for years.

The engineer has not said anything about them so I believe everything is working out so far.
works great - no issues
Fantastic product I have not installed it yet but it looks like it will work fabulously and a lot cheaper so I can get around me
ORDERED A PAIR OF THESE FOR MY TILT TOP TO REPLACE THE ORIGINALS.
THEY WORK GREAT AND ARE MUCH HEAVIER THAN THE 12k's THAT CAME ON IT.
FANTASTIC SERVICE!!!!

Great product and fast shipping!!
This jack went on a customers trailer and has worked perfectly with no issues.
Everything as it should be. Job well done by etrailer.
It was installed on my inlaws trailer as the old took three men and a baby to crank. The new one from you has performed smoothly and reliably, great value.
This trailer jack is high quality and low priced, easy to install.
The jack was delivered days before expected. It is a lot better quality than expected.
I have not installed yet, but I have great hopes. The main reason that I purchased this jack is because I can order replacement parts.
Good Jack's for the money. I use a pair of them to jack up my 25 foot loaded gooseneck a few times a week.
Fast shipping
I would recommend this trailer jack works great

Still working great no problems with any of the jacks
Its a good jack. Unfortunately the only reason its not getting 5 stars is because the spring broke within the first 20 uses. But it still works fine
The jacks seems to be holding up, i use them as downriggers for my service truck crane. Only gave 3 stars because one of the feet on the jacks came bent and etrailer offered to send me a new jack at over $[XX] shipping or some casy back. So i took the $[XX] cash back for my 300$ jack.
This was a replacement for a jack that had failed. Dimensionally it was as advertised. I received the jack ahead of schedule, took it out of the box and welded it in place. Jack works smoothly and now that I have a. new jack it is obvious that the old jack had been in bad shape for quiet some time. This new one is almost effortless.

Works flawlessly.
Great jack only thing is check the grease,instead of putting it on the gears they just put a big blob in the top
Works great
I got 2 of these for a landing gear set up on my bumper pull. Customer service said there is no way to reverse gear to use as landing gear so i set them both to turn in same direction. These are by far the best price ive found. Compared to a local prices i basically got 2 for the price of one. Doesnt appear to have any sacrifice in quality either. Very heavy duty. It only took a few days to get them. Customer service is great and so is the product. If you want to see more of my set up with these jacks, you can view my trailer build videos on my online video channel carvings by levi.
