A close up image shows the ARK XO Series jack's Max Moving Height

Note: Do not use this jack to move your trailer if it's extended past this "max moving height" line.

Designed in the Outback for all-terrain use, this rugged jack is equipped to handle just about anything, from moving your boat trailer to accompanying you on off-roading adventures. You'll appreciate the smooth operation and adjustability for everyday use just as much as you'll enjoy the special features designed for extreme use. From jobsites to campsites, the Ark Xtreme trailer tongue jack will work for you.

Easily Move Your Trailer Over Any Terrain

Ark Jack All Terrain

Dual steel wheels with rubber tires provide increased surface area for smooth, steady travel. The rubber tires can cruise over rocks without breaking or getting flat spots, and the tread helps prevent sliding in wet conditions. The overall strength and durability of these wheels also keep them from stalling in sand or light mud.

Ark Jack Dual Wheels

Sealed bearings act as bushings to hold the wheels in line on the cross shaft. This is an improvement over traditional plastic jack wheels, which often have just a bolt going through them, providing very little stability and causing the wheels to wobble, lock up, and drag over time.

Ark Jack Sturdy Steel Body

The heavy-duty, durable design of this jack lets you take your trailer off-road, over rough terrain, and through various climates. The sturdy steel, square body provides increased side-load capacity and superior strength, and limits play between the tubes. And the corrosion- and rust-resistant zinc finish offers a 600-hour salt spray rating to withstand wet or rainy conditions. The built-in grease zerk lets you lubricate the internal screw when necessary for continued smooth operation over time.

Safe, Easy, Out-of-the-Way Positioning for Travel

Ark Jack Magnetic Handle

A sturdy magnet is built into the jack's easy-to-grip crank handle for secure attachment of the jack crank. The handle detaches easily to store away and prevent hang-ups while traveling, yet it's strong enough to stay put while you're cranking the jack up and down.

The removable handle might also deter would-be trailer thieves. After all, who wants to take a trailer if they can't get the jack to work?

Ark Jack Swiveling Design

The convenient, side-mounted swivel pin has an easy-to-grip handle, making it fast and simple to swing the jack down for use or up alongside your trailer tongue for travel.

Ark Jack Yoke Lock

The yoke latch at the bottom of the jack offers 5 positions to hold the wheels in place. This allows you to tailor the configuration of the stowed jack to suit your needs. So if you have anything mounted on your trailer tongue that the wheels might hit if they're positioned upright, you can lock them in place facing down instead. If you're off-roading and traveling through rough terrain where you might have issues with ground clearance, just lock them upright. This locking feature also keeps the wheels from swinging around while you drive, which will help to ensure that the bearings don't wear out prematurely.

Fast, Easy Setup with Minimal Cranking

Ark Jack Spring Loaded Handle

Once you've arrived at your destination, setting up is a breeze thanks to the quick-release jack tube on the Ark Extreme jack. Just tug the spring-loaded handle to quickly drop the jack tube to your desired height. This handle allows you to set the jack in 1 of 4 positions. Once you have it as close to the ground as it will go, just rotate the crank handle on the front of the jack to fine-tune the height.

Having the ability to drop the jack tube in this manner means that you won't need a drop leg or space fillers like blocks or bricks. And far less cranking is needed to get the jack into position, which will you save you both time and effort.

When you're ready to pack up and hit the road again, hitch the trailer back up to your vehicle, retract the jack's inner tube using the crank, and reposition the jack back alongside your trailer tongue.

How to Determine the Lift Capacity You Need in a Jack

A trailer jack lifts your trailer high enough at the tongue to allow you to couple it with your vehicle. Usually, your tongue weight is about 10-15% of your gross trailer weight (GTW). For example, a 10,000-lb trailer has a tongue weight of 1,000 lbs to 1,500 lbs. To raise the tongue of a trailer this size, you'd need a jack that can handle a static load of no less than 1,500 lbs. And, yes, it's okay to have a jack with a weight rating that is higher than your trailer's tongue weight. In fact, a jack with a higher capacity should operate more efficiently, allowing you to spend less time cranking and more time camping.

What a beast! I just installed it and can't believe how much of a difference it made right off the bat. The versatility of this jack will pay for itself while disbursed camping, or at a campground. Thanks to the etrailer team for a quick response time from ordering to shipping.



This jack proves its worth every time. Still the best decision when I replaced the standard jack on my trailer.

@Jim That's great news! Thanks for letting us know.


I now own 3 of these in different sizes. I started with a 500 series on my utility trailer but needed something a little beefier to hold up under weight in the trailer when I drag it through the lawn, which is why I got the 750. I had a 350 on my 16' boat trailer but now swapped it out with a 500 that was on my utility trailer. All are made tough, well designed and can take punishment. I wouldn't go with anything different at this point. Show me a trailer jack that's better than this!


Excellent heavy duty jack. Best I have ever used.


Love these jacks! I build a machine called a Cornroaster, which cooks ears of corn and there is a lot of tongue weight on the jack, it rolls and turns so easy with this jack, I couldn't be more pleased!!


I've had this jack on my trailer for over a year. It's very durable and well made, and very convenient. I love the multiple ways to raise/lower and swing the jack up and down. The removable magnetic crank handle is awesome. The heave duty construction and dual wheels are very solid, never bend, and reduces sinking into dirt/grass. No regrets purchasing this - awesome product.


Works good but the metal it’s made out of is a cheep white metal that bends very easily. For the price I would expect a better metal.


I thought it would turn easier when not on pavement but it doesn't


This trailer jack is the beast of all trailer jacks. It's definitely heavy duty and will serve your trailer jack needs flawlessly. Highly Recommend!
Shipping was fast and FREE!



I had to replace one wheel because it was deformed. But other than that it still works like a beast. They sent me a replacement wheel right away. I placed some spacers in between the two wheels because I didn't want the wheels to walk excessively. The only concern I have, which doesn't effect its function, is that when extended the leg starts to tilt to the side. Concerning, but not a deal breaker.

I have gotten in contact with the manufacturer and they have suggested that on the XO series trailer jacks they have built in another height adjustment on the side of the square section so you can move the square tube down further and you don’t have to wind out the cylindrical section as far. This should stop you from having the slight tilt you are experiencing.


Heavy Duty! Unfortunately the mounting bolts provided will not fit a fairly standard 3” square bar. Advertisement and previously reviewed responses imply that it would fit. Hardware included only accepts “50mm” wide mounting as stated in the provided instructions.



Trailer Jack continues to work flawlessly after one year.


Very well made , easy to use and very versatile . It would be nice if the wheels were removable , I would like a plate instead and you have to crank ccw to raise . backwards from most jacks .


Extremely pleased that you had this in stock! Easy ordering and fast shipping.


Best jack on the market! Swivels and locks in multiple position, tons of lift power, detachable handle , and the dual wheels make pushing trailer with a dolly a snap. To top it off, you have the best looking jack on the ramp.


So far so good. Durable and has handled what I have asked it to do with ease. The crank handle is magnetically held in place and I often forget to remove it. Handle could be a little beefier as I have bent mine. The cranking system is backwards from all of my other trailer jacks so intuitively you start to crank the jack and it goes the wrong way, no big deal but irritates me.


This was a great purchase. With this trailer jack I can easily maneuver the trailer to fit into a spot. With my old jack it took more strength and took more time. What I like about the jack is it’s locking mechanism when it is in the up position. I also like that the height of the jack can be easily altered for varying terrain. I have had to use this feature several times with good results.


This is a solid piece of kit and there is no rattling or other movement when moving the trailer around.

However, it rattles a lot when stowed and need a strap of some kind to keep it quiet. Very annoying!

The mounting bolts provided were too short by about 10-15 mm to connect both plates across the trailer tongue, so I had to buy new bolts (the replacements were M12 x 1.75 x 90mm)


You are going to think that $xx.xx dollars is to much for a swing- up trailer jack. When you hook this up and see how rugged this jack is, you will understand why it costs so much. I have had a few of the cheeper models, they are a waste of money. The ORJW750D is a great design.Spend the money,You will never have to buy another Jack.


packaging was badly damaged intransit by ups. but it appears there are no missing parts. Trailer jack looks to be well made.


my ice fishing camper has a tougue weight of 900 lbs...i`ve moved trailer around on this jack and no problems so far...very strong


It’s never been easier to move my boat around in the garage. I can’t believe I struggled all those years. A must upgrade for all boat owners.


Great heavy duty trailer jack other than the bolts being too short even for a small trailer tongue. They should provide 100mm bolts not 80mm.


Well built. Perfect application for using on multiple tow vehicles including my lifted F-350. Finally a well built fully adjustable trailer jack that will not be a POS in a year. Well worth the extra money.


Great product,just as expected. However the customer service from Etrailer SUCKS! Item was advertised as "in stock and 3 to 5 days shipping" I ordered this April 14, 2021 and it did not leave the warehouse until May 6, 2021!


Awesome trailer jack. Works perfectly with my Opus 4 offroad camper. This is the jack it should have from the factory.


I’m very pleased with is trailer Jack.


It’s bigger and heavier than I expected. The jack looks and works great.



These trailer jacks are tough and strong. I can even lift my trailer to change my tires.

  • Dimensions of Ark XO350 and XO750 Mounting Plates
    I have attached two diagrams below with the dimensions for the XO350 and XO750. Both of these use a bolt on installation so you really only need to know the height of your tongue to see if it is compatible. The # ORJW350D fits 2" to 6" tall trailer tongues and has a 770 lb static load capacity. The # ORJW750D fits 3" to 6" tall trailer tongues and has a static load capacity of 1,650 lbs and dynamic capacity of 1,100 lbs.

  • Ark Corporation Off-Road Tongue Jacks For Launching Boat Trailer

  • Recommended Trailer Jack For a Home Made Trailer With Wheels For Maneuverability
    I recommend checking out the Xtreme Off-Road Swing-Up Trailer Jack w/ Dual Wheels # ORJW750D for your homemade trailer. This jack allows you to swing the jack which will get the wheels further off the ground when not needed unlike the Square Jack w/ Footplate # MJSQ-2500B you found. We do not have a wheel kit for this jack. While we do not have a trailer jack with pneumatic tires the Xtreme jack above includes steel wheels with rubber tires for durability.
