From jobsites to campsites, the Ark Extreme trailer tongue jack will work for you.

Easily Move Your Trailer in Tight Quarters

Ark Ratcheting Jack Gear Knobs

The ratcheting feature on this jack lets you move your trailer in small, precise increments, which is ideal when working in tight spaces like your garage. Two of the three knobs located at the base of the jack allow you to adjust the direction of the wheel. Pull each knob, one at a time, and turn it to the desired direction - forward or reverse - until both knobs are locked in the same position. The third knob holds the removable ratcheting handle in place. Once you've set the direction of the wheel, just push down and pull up on the handle in a repetitive motion to move the jack in the direction set.

Ark Jack Wheel Positions

With both gears in the neutral position you can move your trailer freely in any direction without using the ratcheting handle. To move your trailer forward, set both knobs to F and ratchet. To move in reverse, set both knobs to R and ratchet. You can also set one knob in the forward position and the other in reverse to lock the wheel. This will prevent the wheel from turning and act as a brake to keep your trailer in place.

Large Steel Wheel Built for All-Terrain Use

Ark Jack Wheel

The large 10" steel wheel with rubber tire provides smooth, steady travel. The tire can cruise over rocks without breaking or getting flat spots, and the tread helps prevent sliding in wet conditions. The overall size and durability of this wheel also keeps it from stalling in sand or light mud.

A sealed bearing acts as a bushing to hold the wheel 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 wheel to wobble, lock up, and drag over time.

Ark Jack 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 Swiveling Bracket

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 latch at the bottom of the jack holds the wheel in place. This locking feature keeps the wheel from swinging around while you drive, which will help to ensure that the bearing doesn't wear out prematurely.

Fast, Easy Setup with Minimal Cranking

Ark Jack Spring Loaded 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 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.

Ratchet this jack to easily move your trailer into tight spaces. The sturdy steel wheel with rubber off-road tire tracks through mud or over gravel and sharp rocks. Easy-to-grip handle lets you drop entire jack tube down for quick adjustment.


I just received the Extreme Off-Road Ratcheting Trailer Jack w/ Wheel - Sidewind - 10" Lift yesterday. (May 16th, 2020). I installed the trailer jack yesterday. Installation was very straight forward. The frame rail of the my car trailer is 4 inches wide at the point where I installed the jack. The recess in the jack mounting bracket for the frame rail was designed for something less than than a 4 inch frame rail. After looking at this recess in the jack bracket and seeing the 4 bolt heads that that protrude into the recessed area of the jack bracket area I do not know why the engineer bothered to make this recess because the 4 bolt heads are what make contact to the trailer frame rail not the surface of the recessed jack bracket. To secure this trailer jack to the frame rail properly IT MUST BE WELDED ON. THIS BOLT ON JACK BRACKET IS A JOKE! I plan on keeping and using this jack because of all the other great attributes and quality of construction this jack has. After I am convinced that this trailer jack will work properly in this location I will weld the bracket to the frame. 799055

The recess in the back of the jack is designed to accommodate the bolt heads while the mount is what contacts the trailer frame. This jack is designed to bolt to trailer tongues ranging from 2 inches - 6 inches, so it is designed to fit your 4 inch trailer tongue. If the bolts, not the mount, make contact with the mounting bracket in one orientation, do the bolts still make contact if the mounting bracket is rotated 90 degrees? The jack can be installed with the mount in either the horizontal or vertical direction.
