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
Extremely heady duty
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.
Good design
Great product. Have not installed yet. Quality much better then your average trailer jack
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.
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.
Loving it! Easy assembly and the quality is amazing. Probably over kill for my 5x8 carry-on Overland trailer.
Much better than the standard trailer jack. However, like other reviewers, I needed to purchase longer bolts for my application. At this price point, bolts in various sizes should be provided by the manufacturer.
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.
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.
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.
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.
Do you have a question about this Trailer Jack?

After one year of use the jack continues to work great.
