Features to know about

Built for Rough Terrain: Dual Steel Wheels with Flat-Free Rubber Tires

Dragging a trailer through mud, gravel, or sand is where most jacks give up—but not this one. The Ark Xtreme Off-Road Swivel Trailer Jack uses dual 8" x 2" steel wheels wrapped in flat-free rubber tires that grip and roll smoothly over rocks and soft ground. Sealed bearings keep the wheels aligned for steady movement without wobbling or drag, so maneuvering by hand stays controlled even when the ground isn’t. It’s built for off-roaders who need a jack that moves anywhere, not just on pavement.

Easy Setup Anywhere: Quick-Release Drop Tube and Sidewind Crank

Getting set up shouldn’t mean endless cranking. This jack’s spring-loaded handle lets you drop the tube into one of four positions for fast ground contact, cutting the work down to a few turns of the side-mounted crank. With 10" of screw travel plus an 8" drop leg, you get a total lift of 24-3/8"—plenty for uneven terrain or taller setups. The removable magnetic crank handle stores easily when not in use and snaps back in place firmly when you’re ready to go.

Strong, Quiet, and Built to Last: Heavy-Duty Steel with 600-Hour Salt Spray Rating

Off-road hauling means mud, rain, and salt exposure, so Ark built this jack tough. The square-tube steel body adds side-load strength and reduces play between the tubes, while the black powder coat finish and zinc plating provide rust protection tested to a 600-hour salt spray rating. Precision-machined tubing cuts down on chatter, and a built-in grease zerk makes it easy to keep the screw lubricated for smooth action over time. It’s the kind of durability that holds up for years of rough use.

Travel Ready: Swivel Mount and Locking Wheel Positions

When it’s time to move, the side-mounted swivel pin swings the jack up flat along the trailer tongue, and the wheel yoke locks into five different stow positions to clear any mounted gear. The locking latch also keeps the wheels from spinning during transport, protecting the bearings and preventing rattle. The result is a clean, secure travel setup that’s quick to deploy and just as quick to stow.

Heavy-Duty Capability: 1,650-lb Lift, 1,100-lb Dynamic Load

Whether you’re positioning a camper, boat, or utility trailer, this jack’s 1,650-lb lift capacity and 1,100-lb dynamic load rating give it the muscle to handle heavy tongues without strain. Built for real-world use from job sites to remote campsites, it’s compact for the lift range it provides and solid enough to earn its place on any serious off-road rig.

Video Transcript for Review of Ark Trailer Jack - Xtreme Off-Road Swivel Trailer Jack - ARK39FR

Hello neighbors, Steven here with etrailer.com. Let's take a look together at this Arc extreme off-road swivel trailer jack with two wheels and it's a side wind jack with a 24 inch lift capacity. So folks, this will support and lift and lower the boat or recreational trailer. It does take you places that those plastic caster wheels simply cannot. It's been designed out in the Australian Outback, so it is made to withstand up to the rigors of those kind of terrain. So mud, dirt, rocks, water, those kind of things.

So the wheels are really rugged, it swivels. So you can go either way you need to, the handle and everything. Super easy to crank up or down., and one cool thing about the handle is it's simply held on with that high capacity magnet or a high magnetized magnet. So that's gonna turn that you can take the handle off when you're not using it, but when it's time to use it, it'll snap in place, and it is strong enough to where it's not gonna go anywhere. So the neat thing with this is that again, those tires are what we call flat free tires, meaning they're never gonna go flat 'cause they're already hard rubberized and you don't have to worry about them going flat.

The mount here, there are one, two, three, four different options on height. I'm gonna go ahead and drop this here real quick if I can. So that's gonna rise or lower. So picture this being mounted onto the frame of your trailer and then you can simply pull that spring loaded lever, quickly drop the whole leg to it's touching the ground or as close to those notches you wanna locked in, obviously, close to the ground as you can, and then simply having to crank the handle maybe a few times or whatnot to finish getting at the height you need. And then on top of that, you got this heavy duty spring loaded guy over here that you can pull.

And then that'll all keep it and let it swivel up or down. So zooming in, keep in mind I got this propped up so bear with me. But again, this nice ergonomic oversized handle here. You pull that out and that's gonna let the jack swivel up or down the whole assembly when you're done doing your jack up or down, you can pivot up outta the way to sideways and then it's up outta the way. You get the mounting brackets and the bolts.

It's not gonna shake or rattle during operation and it's been powder coated, a nice coat finish. It's been tested with a 600 hour salt spray rating should last for years, thanks to the durable steel construction and everything. The trailer frame fit guide, it needs to be between three and six inches tall for these brackets to fit and operate correctly. The lift capacity is 1,650 pounds with a dynamic load capacity of 1,100 pounds. Now when this guy is fully extended, it can be 33 inches fully extended and when it's retracted it's 12 inches, meaning 12 inches from the top of this bracket down to the ground, under the wheels and everything. So that's about 24 inches of lift if you do the math. Now these wheels are an impressive eight inch diameter by two inches wide. Lemme see if I can carefully spin that for you, give you a little better view there from the side. So again, two inches wide, eight inches in diameter. And again, nice big heavy duty, easy to roll. And then once again, you can see this handle from the side, just simply being able to pull that and let this whole jack pivot up and out of the way just makes it so much easier whenever you're doing those heavy trailers and stuff, and just in general. Well folks, I think that's gonna wrap it up. A really nice extreme offroad swivel jack. This is the Arc extreme offroad swivel trailer jack. I'm Steven. Thanks so much for your time. Thanks for watching and have a great day.

Thanks to the communication with Breanna, my order and an additional part it made the process exceptionally easy! As far as etrailer, they are on the ball with shipping and the tracking information is the best in the business.
Thanks etrailer and Breanna!

I like the beefiness of this jack. The different adjustment levels is really key since I have an off-road trailer



by:

Best trailer tongue Jack I’ve ever owned, period. These should be standard in everything and will be on everything I own from here on out. Makes moving the trailer around the garage virtually effortless.



by:

This is mounted to my off road trailer. I've tried two other designs and they either came apart after a while or didn't turn in dirt. This one does lock up and out of the way nice. The ability to lock the wheel in the up position is a must for off road travel. My only regret was not buying the quick release version.

It’s a beast in own league. Sturdy and well made. Will last a long time



by:

Worked out great



by:

Note that this may be designed in Australia, it is made in CHINA. Box arrived damaged and minor paint scraping on the product. It is heavy duty but it is obvious the screws, bolts, nuts, and springs are lower China quality. Too early to say how long it will last. It does go TALL and is the only tongue jack I could find that would crank two feet up. Mounted on my DoDrop Alpha teardrop camper.



by:

Sturdy. Great design. And a welcome change from the OEM jockey wheel that it replaced.



by:

Outstanding product and service



by:

Great modularity to work under wide variety of variation. We spend lots of time in remote places and rarely park on flat earth, this rig performs awesome no matter where we go.



by:

Beefy jack lifts the trailer high enough on uneven surfaces!



by:

Super heavy duty, and seems very versatile in a variety of environments. Lots of detail, show this is a serious product. From the name stamped into the wheels, to the locking pin to keep the wheel from spinning. Made from obvious off-roaders.



by:

This is my second Ark product. Needed something with a higher load capacity than the Ark 500 I already own. The Ark 750 is much more robust, exactly what I was looking for.



by:

Very heavy duty design. Compact for the amount of travel it has and the wheels are perfect for trying to maneuver on rough ground.



by:

This is a replacement for a prior one that I broke (my fault). It has several improvements over prior models, including a longer reinforced sleeve that contains the telescoping jack.



by:

Perfect for a shorelandr trailer. I have it on a 25' 252SD and raises the trailer with ease and stores much better than the original garbage.



by:

Great Jack, great service, fast free shipping. etrailer does it right, very satisfied.

The ARK jacks are well designed and sturdily constructed, once you have one you're ruined for life.

Picture is installed on my 2026 Cube Series trailer, frame is 2x6 aluminum, 24 inches to the ground, this jack is perfect.

Having said that the jack that I bought (XO750 XL) is the extra long version which is what I wanted. It does not say XL in the product description and it should.Reading the specs is the only way to figure it out now.

See what our Experts say about this Ark Trailer Jack

  • Recommended Trailer Jack for a 5'x8' Utility Trailer
    Hey Jeanie, I think only 12" of lift is going to be a bit too short based off of your measurements. Instead, I recommend going with the Ark Xtreme Off-Road Swivel Trailer Jack w/ 2 Wheels # ARK39FR which has 24" of lift and collapses to 12" when fully retracted. This jack also has a 1,600 lb weight capacity which should be plenty for your utility trailer.

  • Availability of Replacement Plastic Piece At Top of Fulton 1600 Marine Jack
    Hi Trevor; I'm sorry to say that part isn't something we have available. A lot of the replacement parts for Fulton started to disappear after they were acquired by First Brands. You can try to contact them directly to see if they have it but, they usually aren't very responsive. If you are unable to find the part I recommend replacing the jack with one like the Ark # ARK39FR you were looking at. Was this on your boat trailer?
