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 Extreme 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 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.


Ark Jack Stowed Along Trailer

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 Release 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 3 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 is designed to lift the tongue of your trailer so you can connect the trailer coupler to your hitch ball. To do this, you'll need a jack with a lift capacity high enough to handle your trailer's tongue weight.


Tongue weight is the amount of weight that your trailer applies to the back of your tow vehicle. Typically, your tongue weight should be 10-15% of your total trailer weight (trailer + cargo). In other words, a 10,000-lb trailer would have a tongue weight between 1,000 lbs and 1,500 lbs. For a trailer this size, you would need a jack with a lift capacity of at least 1,500 lbs.


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 lift capacity should operate more efficiently, allowing you to spend less time cranking and more time camping.


Trailer and Camper Jack Lift

Every jack offers a certain amount of lift or travel. Screw travel is the distance the jack extends when you crank it (or toggle it to "extend" on an electric model). Some jacks include a drop leg for extra adjustability. On these jacks, you'll see the maximum extension of the drop leg listed in the specs as well. Adding the screw travel and drop leg travel together will give you the total lift. The total lift listed above can help you determine how high this jack will be able to raise your trailer.

This trailer jack is truly "extreme". I was looking for an over-built one that I could count on to take some abuse. This one is perfect. The pins have extra strong springs. The back plate is extra thick. Even though I didn't need to use them, the bolts and brackets it came with are extra beefy. The wheels are extra strong. Basically everything about this jack is completely [awesome]! My favorite feature is the removable magnetic crank handle. It clicks into place with authority and stows in my tongue box. Also, it looks great too. I'd buy this again in a heartbeat...only thing I'd do different is get it sooner. I put up with the wimpy OEM trailer jack far too long.

Check online for accurate measurements. The measurements provided on the etrailer site are not accurate in many cases for the Ark Jacks. I went over the measurements in detail with etrailer Customer Support prior to ordering and specifically went over the tongue width - which is the primary measurement you need as the mounting screws go horizontally. They confirmed the mounting hardware would work. If you have a 3" tongue, the provided screws will NOT work. When I contacted etrailer Customer Support, they say just says go to the Hardware Store.

This is, by far, the best quality jack I have ever seen! This one should last a lifetime! Thank you!

It’s a very nice Jack. The only thing that could be improved is the bearings coming already mounted in the wheels. I had no issue installing them but the average person may have an issue. Works great



- ORJW350D

Pushes better than the single wheel I had on my boat trailer, but the height range is very limited for a jack in this price range. Has a removal handle as a theft deterrent. I like it overall.

Everything the ad and the nice Reps say about it is true, so that's good. Out here in the middle of the Mojave Desert mounted on my trailer it gets a good workout when exposed to high (65+ mph) winds & blowing dirt, just sitting there. The blowing sand jams all of the mechanisms; there isn't really any lubricant that can prevent that. The magnet-mounted crank handle hasn't rattled off yet on the road, which is spectacular. However, if it gets trailered along a road where the washboard puts the hitch handle into a vibration I would expect the handle to fall off. The manufacturer needs to drill the holes undersize for the pivot release and the raise/ lower release levers then ream the holes to size for a bushing instead of slopping them through oversize machine-punched holes. The aforementioned blowing dirt jams all the pivots. I suppose if you only use it where there are peat bogs and glaciers this wouldn't be a concern. I bought the most expensive jack etrailer had under the theory that it'd be the easiest to use. I'd pay another $100 if they would make all the pivot points proper instead of what it is.

Super solid and heavy duty. Wheels and wheel bearings are ver rugged. I launch from some spots that require me to disconnect my trailer from my truck and "wrangle" the trailer - This will make that a lot easier!

Jack does not have enough lift for my application, the 500 series is what I should have ordered but I was told the 350 series would be adequate.

This my seem an expensive choice and well it is. You can buy cheap if all you want to do is roll your trailer around on a garage floor or smooth hardened surfaces. I purchased it for soft ground, dirt, gravel etc when out camping with a smaller 1800 lb trailer to be able to position it easier. The quality of build is excellent and seems like it will stand up to a lot of punishment and use when out camping. Assembly and installation was extremely easy. The drop down feature that allows you to lower it without having to crank it all the way down is a nice touch. I read reviews, watched videos etc and they are accurate, this is a quality product, and depending on your intended use would be a great choice.

i would have to remove my old jack when i was using my trailer, now i can leave this one on my trailer all the time, its very sturdy jack, with dual wheels made it easier to move, like i said this is a very sturdy jack and should last a long time

This jack is exactly what I was hoping for. I manually push my boat around my driveway and into my garage. This is the first jack and wheel that is user friendly for doing this. I’m saving a lot of curse words every time I maneuver the boat with manpower. Thank you!

We ordered this trailer hitch after doing some research and looking at what other people thought who have installed it. It seems to be a good choice for what we want it for. We are having it put on a teardrop trailer. We will let you know how we like it after some use. The hitch was shipped very quickly! Nice job to the professional woman who took our order over the phone and kudos to shipping department! Thanks! Sincerely Randy and Sarah

Ask the Experts about this Ark Trailer Jack

  • Recommended Extreme Off-Road Trailer Jack w/ Dual Wheels for 23 Inch Trailer Frame Height
    If you are needing your trailer frame to be 23" from the ground to the top of the frame then I recommend going with the Extreme Off-Road Trailer Jack w/ Dual Wheels # ORJW500D with the 18-3/8" lift because the part # ORJW350D with the 12" lift will be just shy of what you are needing (just under 22"). The 18-3/8" lift actually has a higher tongue weight rating too so you don't have to worry about that.

  • Can ARK Extreme Off-Road Trailer Jack # ORJW350D Replace Fulton F2 on Trailer Tongue
    I went out to our warehouse to take a few measurements on the mounting bracket for the ARK Extreme Off-Road Trailer Jack # ORJW350D (compared to the mounting pattern for your existing Fulton F2) and found that they differ enough that you wouldn't be able to bolt it to the current weld-on plate on your trailer. With that being said, you can still use this particular jack without using the welded plate because this doesn't share the same mounting style as the Fulton F2. The ARK Extreme...

    When a weight is listed for a trailer jack like the ARK Extreme Off-Road Swing-Up Trailer Jack w/ Dual Wheels - Sidewind - 10" Lift - 770 lbs - Zinc # ORJW350D, it's referring to the maximum trailer tongue weight it can safely lift. For your trailer with 120-lbs to 160-lbs, this would be a great choice! ARK makes really high quality parts, especially for off-road trailers, and I think you'll be really happy with this one.

  • Can the Extreme Off-Road Swing-Up Trailer Jack Be Installed On Either Side Of the Trailer
    The Extreme Off-Road Swing-Up Trailer Jack w/ Dual Wheels part # ORJW350D can be mounted on either side of the trailer. In regards to security, this is not really an issue that we have had others experience. It is possible to take the jack off the trailer but there are several bolts and it would take more than one one tool to do so. I can't say the tongue jack is a common item for theft on trailers but it's possible.

    The wheels alone are not something that can be purchased separately from the Extreme Off-Road Swing-Up Trailer Jacks, so if you wanted the benefits of the jack's steel wheels and off-road rubber tires you would need to get the whole jack.
