Soft sand, gravel, and uneven dirt can make moving a trailer feel impossible, but this jack rolls through it all. The Ark Xtreme Off-Road Jack uses dual flat-free rubber tires on steel rims for extra surface grip and stability. Sealed bearings keep the wheels spinning freely without wobble or drag, even under heavy load. With a 1,100-lb static capacity and 17-1/2" total adjustment, it’s strong enough to handle real-world terrain while staying smooth and controlled on any surface.
Getting your trailer set up doesn’t need to be a workout. The jack’s 10" lift and 7-1/2" drop leg let you reach the ground fast, no blocks or bricks needed. The removable magnetic handle is easy to grip and won’t rattle loose while traveling. Just pull the spring-loaded release, drop the tube into position, and fine-tune your height with the sidewind crank. Four adjustable height settings make setup quick whether you’re on level pavement or sloped ground.
This jack was built for the Outback and it shows. The square-body steel design adds side-load strength and cuts down on play between the tubes. A premium zinc finish with a 600-hour salt-spray rating protects against corrosion in rain, mud, or coastal air. The built-in grease zerk keeps the internal screw lubricated for smooth, long-term operation. Whether stored outdoors or hauled through wet conditions, it stays solid and ready to work.
Once the trailer’s hooked up, swing the jack parallel to the tongue and hit the road. The easy-grip swivel pin makes rotating it fast, and the 5-position yoke lock keeps the wheels where you want them—upright for clearance or down for compact storage. Precision-machined tubing limits chatter and rattle while you travel, so you can focus on the drive instead of the noise.
No welding required. The Ark Xtreme bolts directly around trailer frames 2" to 6" tall using the included hardware. The heavy steel clamp and four-bolt pivot point hold firm under load and prevent bowing, even when maneuvering on soft ground. It’s a solid, long-lasting upgrade that makes parking, launching, or positioning your trailer by hand smoother and easier every time.

The jack is a great design and is very well built and operates smoothly.
I needed this for launching and landing my sailboat using a 20-foot cable between my truck and trailer. This jack worked perfectly to use as the trailer was able to go much deeper on the ramp. I couldn't be more pleased with its performance. I would buy it again and I would recommend it to a friend. The trailer/sailor market has been needing this double-duty trailer jack.
Ok, I should have bought this a long time ago. On a recent trip to Baja we got stock and needed to move the Trailer. No way in the sand with that other wheel. It was also impossible for my partner to stow.
This thing is awesome, solid mount, ball bearings in the double wheels, easy to position and stow. Two minor complaints, the handle is magnetic and does not attach solidly, so a possible losable item on a trip. also the bearings are not sealed in any way so I am a bit worried about dirt getting in. So we will see how this holds up long term but so far it was definitely worth spending the extra money. After all, you really do get what you pay for with some of this cheap stuff.
It's a great addition to my trailer one person can move is around on concrete pavement/asphalt driveway’s.
Purchased this jack because I roll my boat in and out of garage and I added tongue weight adding bigger trolling motor and steps for trailer. Not sure whether my other jack could handle the weight. The Extreme jack can handle the weight but hasn’t made it any easier rolling boat in and out of garage. It’s a lot smoother with the rubber wheels but they don’t flip around any easier than my other jack when trying to change directions.
Upgraded the swing-up jack on my Tribe Trailer Basecamp. Installation required rotating the Xtreme mounting plate 90 degrees and drilling two new mounting holes on the Tribe Trailer bracket. The Xtreme is a big upgrade in quality to the stock Basecamp swing-up jack. Most important the trailer is now very easy to move across slightly uneven gravel / dirt terrane. Pleased with the purchase.
This is a fantastic product, but what I have really been impressed with is the customer service of etrailer. They have been extremely helpful, efficient, and friendly. I will be purchasing all of my trailer parts from them in the future. I highly recommend them.
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!
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.
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!
Super strong and smooth as butter! I needed to get longer bolts but otherwise the installation was very easy.
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.
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.
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.
Extremely well made easy to install. My off-road trailer came with one originally and I put it through a lot of abuse off-roading dragging the trailer around and lasted for several years.
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.
Excellent tongue jack. Trailer rolls so much easier compared to my old jack. Easy to reposition the trailer.
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.
I received my Ark XO 500 Extreme Off-Road jack today and it was much better than I anticipated. I’m using on a Shorelander trailer with a Yamaha AR195 19 foot boat with approx a 500 lb tongue weight. I know this jack might seem like overkill for my application but I would rather go with safe than sorry. This thing is robust. Definitely well built. Apparently the manufacturer listens to these reviews and has upgraded a few things that I was a little worried about. First. The wheelbearings are now installed at the factory. That’s a homerun for anyone that has anxiety having to press wheelbearings in the rims like me. Also, another point of concern was the magnetic handle. Well now they give you the option to use the included bolt and washer to permanently fix the handle to the crank and that’s what I did. Just pop out the magnet with a screw driver and screw the handle on. Simple. For my application this fit perfectly right behind the riser that holds the bow roller. I have a folding tongue so this was my only option. Function is great. With the square tubing lowered to its lowest it took about 6 cranks to get the boat at a good height to drain. Crank turn is butter smooth. All adjustments work perfectly. The only bad thing and I hate to mention it because it’s been brought up many times before. If your trailer has a 3 inch thick beam you will need longer bolts. The bolts included are M12x1.75x80. To short for 3 inch application. You will need M12x1.75x100 and you will be able to use the included Nylock bolts. Overall a great purchase. Of course I have to see how it holds up to the harsh environment of salt water. The instructions give you details on how to maintain the unit to insure longevity. I will update this review in a year or two on how it holds up.
I replaced the jack that came with my off-road utility trailer with this one and it was a vast improvement! It is well thought out and built to last. The only missing feature I wish it had was a brake for the wheels.
This is a great wheel jack that works much much much better than a standard wheel jack. The adjustments are great on it and it’s nice and powerful and easy to use.
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.

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.
Great product. The provided mounting bolts aren't long enough for my trailer tongue. Need to go to Home Depot, waste time, and get new bolts.
This really ticks me off. Other than that, I think the product and functionality is fantastic.
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.

After one year of use the jack continues to work great.
It certainly looks and feels super sturdy! We camp with it next weekend. I expect it’ll be pivotal in being able to move the camper when dispersed camping on all types of ground. Our old jack was bending outward, and I felt certain it would fail soon! Was excited to see this one is super sturdy and has a way to lock the wheel in place when traveling.

Actually, I have had to replace this wheel jack. The gears in the top of the unit broke or wore down but somehow they would not turn. Then the main shaft above the wheel got bent from rolling it while mostly extended because we could not crank it in. I do not think that the gears are beefy enough.
