Getting a heavy trailer level doesn’t have to mean endless cranking. This RAM square direct-weld jack uses a drop leg with a spring return that adds 13-3/4" of height on top of 15" of lift, giving you a total of 28-3/4" of total adjustment. Just pull the front-facing plunger pin and let the leg drop—no need to stack blocks or waste energy. The footplate keeps the jack steady and prevents sinking into soft ground, so setup is quick wherever you park.
Whether you’re hauling equipment, loading a heavy trailer, or parking for the season, this jack is built to handle the load. The 1" jack screw and twin thrust bearings provide smooth, strong operation that doesn’t bind under pressure. It’s rated for 12,000 lbs of lift and 15,000 lbs of support capacity, giving you solid confidence when raising or stabilizing even heavier setups.
The effort it takes to crank a jack can make or break your day. This model uses twin thrust bearings that keep the motion smooth and consistent, even under weight. A built-in grease zerk makes upkeep simple—just a few pumps keeps everything turning effortlessly. Reviewers loved how easy it is to keep lubricated and how solid it feels in use.
This jack is made for real-world use. The black-painted inner and outer tubes protect against rust and wear, while the 9" x 9" footplate spreads the load for stability. It welds directly to your trailer frame for a permanent, heavy-duty mount. The sidewind handle (TJD-12000-HD, sold separately) can be locked down for travel with a weld-on clip (TJD-12000-CLIP, sold separately), keeping everything secure when you hit the road.

Hello everybody, Steven here with the etrailer.com. Let's take a look at our square direct weld on jack with a nice drop leg that has a spring return, and it's considered a side wind jack. Now, this jack is gonna be rated at 12,000 pounds capacity. It is a heavy duty utility jack that lets you raise and lower your trailer as needed. So, it'd be great for agricultural, commercial applications, those kind of things. And the drop leg here with the spring return is gonna increase your overall extension from maximum adjustability, and whenever your jack is welded up in place on the trailer, you can pull that push down the foot plate, and it just helps it go up and down a little bit quicker as well.
Now it does have a very durable one inch jack screw built inside of here that allows for heavy lifting. You got a couple of grease zerks here on the front that's gonna be for your maintenance, keeping everything nice and greased. And it uses twin thrust bearings to make extending and retracting the jack really easy. Now, you will need a side wind handle, sold separately, and then you could also potentially get a weld on clip to hold that jack handle in place. Now the foot plate here is a nine by nine inch foot plate.
It's gonna help minimize sinking into soft ground. Once again, this will need to be welded onto the trailer itself. So once again, lift capacity, 12,000 pounds, support capacity 15,000, the total travel is 28 and three quarter inches of travel. Now when it's retracted, it's 27 and one eighth inches tall. And when it's fully extended, it goes up to 41 and seven eighth inches extended.
This outer tube here is a four and five 16th inch square by square all the way around, while the inner tube down here inside is a four inch by four inch square. Now this spring holes, there's gonna be holes up and down that inner tube. You can't see 'em right now because the jack's too heavy for me to lift and pull it down, but there's holes in there that are spaced three and three eighth inches on center. And once again, the jack screw diameter is a one inch diameter. So as you can see, you can go up or down by simply spinning that with the handle and then potentially connect a connection rod to another follow jack, or another jack on the other side.
And that's gonna wrap it up, folks. I'm Steven. Thanks for watching.
