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.
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.
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.
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.
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?
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.
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.
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.
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.
Mounted it easily
This thing is great. You get what you pay for. It looks good, very strong, and rolls around on marginal terrain rather well. It is really a bit over dutied for my application which is on the front end of a M416 trailer.
Shipping from etrailer was very fast.
Great tongue jack. So much better for one person to move the trailer. Some have complained about the bearings not being factory installed. It is very easy to install them if you have any mechanical aptitude at all. Great look in black.
This is a solid trailer jack but NO WAY should the customer have to insert the bearings into the wheels! I have never seen such a thing and they were IMPOSSIBLE to get them in! I had to pay the guy who welded the jack to my trailer to install them. For $300+ dollars this should not be necessary!
The box that the jack came in was literally falling apart and held together with zip ties! I’m amazed it made it in one piece! Not impressed.
A bit of a challenge to install, but really great once installed. Rolling and maneuvering the trailer in my back yard was easy and smooth. A vast improvement over the original jack that came with the trailer. For installation, I would recommend installing the jack on the trailer before putting the wheels on the jack. That not only makes the jack lighter for installation, it makes it more balanced and easier to manipulate for installing the bolts/brackets. Also, the instructions imply that you can simply insert the bearings into the wheels, but they actually have to be pressed or hammered in, which is not unusual for putting ball bearing assemblies in a race. I placed the wheel on a board and placed a small wood block on the bearing to drive it in with a rubber mallet. Once installed, the jack is great, but an installer should have some mechanical skill.
Do not use the Ark 500 trailer jack on boat trailers that are exposed to salt water!
The product info says that jack has been tested for 600 hours of salt spray, well it didn't work out that way for me.
I purchased this jack ~ 18 months ago, so it is out of the 1 year warranty period, to my dismay. This is a very expensive trailer jack, and I was hoping it would last longer.
I thoroughly rinse my boat and trailer in fresh water after each outing. I kept grease topped up in the fitting. Now the jack is getting very hard to crank, gears are binding, and rust is running down the the jack extension leg.
I am going to have to replace the Ark 500 jack with another product, as the day is coming where this jack will not crank any more.
I am very disappointed at the short life of this product, and the short warranty period.
Thanks for reaching out. The Ark trailer jack is well made and we are very pleased with the product. We have had a few challenges in mounting it, however.
We have an InTech Luna camper and it has an all aluminum frame. We purchased the Luna the first year they were manufactured and the tongue is just 2 inches deep. (InTech has since beefed up the frame and tongue on their more recent models, but we have what we have!). The Ark Extreme Trailer Jack is designed for a deeper tongue so my husband has done two things:
First, he purchased a couple of appropriately sized aluminum square tubes that sit above and below our 2 in frame and provide "up and down" stability to the jack
Second, he inserted rubber sheets between the aluminum tongue and the steel jack to prevent corrosion between the metals.
The Luna is light enough to hand push around at home and at our campsites and the original low weight jack just wasn't working. This jack is sturdy and easy to maneuver and we are very pleased.
I had heard the reviews of the 'off-road' trailer guys singing its praises, so for this much money it better live up to the hype. Well, it does. Not only is it heavy duty, but the options that allow it to store, extend etc.... make it a great purchase. I installed mine on a oversize teardrop trailer that will not be going off-road much, but I got sick of those other trailer jacks not wanting to turn the wheel and just dragging it sideways when the camp area is not perfectly level/firm. Won't happen with this one due to the design of the wheel mount. One downside is that is heavier than any jack I have had before, but that is the price of a well built unit, so I can live with that.
One interesting feature is that the raise/lower handle is magnetized on, so it doesn't catch on anything during transport. Sure enough, the first time using it, I left it for a 2 hour highway drive home and it was still there. whew.
All things considered, I am very happy with this purchase, even with the premium price.
This is the best made trailer jack that I have ever owned. The wheels have ball bearings and steel rims. The jack has a grease fitting and the cap on top can be easily removed to grease the gears. Mounted to my 6"x2" frame with no problem. The swing and telescoping features are easy to use. I would purchase it again.
I used this to replace original tongue jack on my Hiker Trailer. Fit was perfect, easy / quick install. Now moving the trailer both at campsites and garage nearly effortless!
The XO500 was an excellent upgrade to the stock trailer jockey wheel on my Off Grid Trailer. It's much sturdier and far easier to swing the trailer around--especially when off road. This was an easy bolt-on solution to the existing jack mounts (and bolts) with no drilling required.
Wow, this jack is the real deal! Love the flexibility of mounting the plate veritcal or horizontal. I chose horizontal to get more plate flat to the trailer frame. Added some 1/4" galv. plate on the back side of the frame to give the brake line clearance from being pinched. This jack is so worth it!!!

Its been a whole year of use with many trips and I wholly believe this is the best jack on the market!
The jack is a great design and is very well built and operates smoothly.
etrailer was very prompt with shipping and made for an easy transaction. Had to buy my own installation nuts and bolts as the ones provided are too short and the blue cap on the jack was smashed during shipping. Not a huge deal I suppose. Overall the jack looks to be nice and sturdy and a solid product.
It's a great addition to my trailer one person can move is around on concrete pavement/asphalt driveway’s.
Very pleased with prompt shipping and the product itself. This is exactly what I needed for my teardrop trailer now I can move it around all by myself, over any sort of terrain. No more worries about not backing up to hitch perfectly.
This is my second one !
Super strong and smooth as butter! I needed to get longer bolts but otherwise the installation was very easy.

I reached out to the manufacturer who advises that it is important to dry the metal on the jack after rinsing it with fresh water. You can use a silicone spray on the jack as the spray does not dry sticky. Salt water with any jack is difficult to combat.
