Level and lift a heavy trailer with two 12K hydraulic legs, each powered by its own 12V pump. Independent controls let you adjust either side separately, while 24" of lift and a 24K combined capacity handle demanding trailers.
Heavy gooseneck, cargo, livestock, and equipment trailers can put a lot of weight on the landing gear, and uneven ground can leave one side sitting higher than the other. This Bigfoot system gives you 24,000 lbs of combined lifting capacity with two 12K hydraulic legs, each providing 24" of lift.
Unlike a shared-pump tandem system, each jack has its own hydraulic power unit. That lets you operate the two sides independently, so you can raise or lower one side as needed to level the front of the trailer. Each jack also uses a 10" x 10" pivoting foot for a broad contact point on the ground.
The wired control panel has separate extend and retract switches for the two jacks, letting you operate either side without moving between separate controls. Both pumps run from your trailer's 12V electrical system, and the kit includes the battery cable and 120-amp circuit breaker needed for the dual-pump setup.
You supply the 12V battery and slightly less than 6 quarts of Dexron III ATF. The system calls for at least 4-gauge battery cable and a solid ground through the steel mounting structure or a separate frame ground.
These are Bigfoot's standard pumps and do not include built-in manual overrides. If the trailer loses 12V power, the system does not provide a separate manual way to run the pumps. Either pump can be relocated if your trailer layout calls for a different position; longer hydraulic hoses are required and sold separately.
The adjustable B-brackets are designed around trailer frame sections from about 3-5/8" to 5-1/2" wide. They can bolt through a vertical bulkhead frame section, or the jacks can mount directly to the frame when your trailer layout calls for it. Bolt-on does not mean every trailer already has matching holes, so compare the mounting area before installation and plan to drill where necessary.
Set the jacks so you have at least 8" to 10" of ground clearance at ride height. Mounting hardware is included, but thicker trailer frames may require longer bolts.

Hi everyone. Steve here with etrailer. Let's take a look at the Bigfoot Hydraulic Jack set with dual pumps. Folks, this is a heavy duty capacity and versatile setup. Lift capacity is gonna be 24,000 pounds total. Now the dual pump setup is really nice because it's gonna give you that versatility to adjust side to side if you're on uneven surface on one side or something of that nature.
And this is great for cargo, livestock, heavy equipment trailers that are either bumper-pull, goosenecks, those kind of things. And you're gonna get the complete package. You're gonna get all the hardware required to bolt it onto your trailer. So again, no welding, that's gonna save you time and money, simply bolt it in place. You're gonna get this nice lockable dual remote control, meaning you can go up or down on that side and this side and then you can lock it to where no one can mess with it when it's not in use.
And you get a nice length, generous length of wire for that. The brackets and everything again are welded in place. On here, they measure four inches tall by seven and a half inches long. And then these little guys match up two 'em that same four inches tall. And then that gives you movement if you need to slide it around again with the included hardware to set that up.
Now what's not included is inside of these housings you have a pump, a reservoir on each side. Each one individually requires about three quarts of ATF Dextron III individually. So you're gonna need about six quarts of that ATF Dextron III to complete your installation. And you're also gonna need obviously a 12 volt battery source to power those pumps. They have a black gloss powder coat finish, so they're heavy duty, very durable to handle, corrosion resistant, those kind of things.
The foot plates are flexible, so they pivot. I just have wedges in there for safety right now so they don't tip over on me. But those can pivot pretty much pretty a distance each way. Again, that's gonna help with leveling things out on uneven surface. They measure 10 inches by 10 inches square on the foot plates. A height overall from the top of the jack to the bottom of the foot plate. When it's fully retracted like you see now, I got 34 inches. Now per the manufacturer, it's gonna be 55 inches tall overall when it's fully extended. I don't have any fluid or battery here to verify that exact measurement, but it should be around 55 inches from bottom to top when it's fully extended. And again, folks, everything here is high quality, heavy duty. You can technically remove these power unit boxes and move them if you want to. They just simply bolt on. Just keep in mind if you move them for whatever reason, maybe you don't wanna, you don't have the space for everything, but you have the space for the jack legs, you can move these, you may just have to purchase separately, some longer hydraulic lines to then, you know, move it to wherever you need it. That way it can reach and do its thing. And keep in mind, if you do get longer hoses, you may potentially have to put a little bit more of that ATF fluid in there, but you may not also. So again, just follow the instructions and as always, you can reach out to us here at etrailer. We'll answer any question we can. We love helping people out. We wanna make sure you get the right thing the first time. That's gonna wrap up our quick look together. I'm Steven, thanks so much for watching. Have a great day.

Shipping something this heavy should be put on a pallet and strapped down so UPS can’t loose a box or roll it down a mountain. That’s what one of my jacks looked like when I finally received it two weeks later. And still haven’t received one of my jacks .
