The Ultimate Trailer Jack has a wide range of adjustability and it is easy to use, making it a dependable choice for your A-frame trailer. Its adjustable design allows for maximum clearance, drastically reducing the potential for damaging hang-ups. The jack also features an outer tube that extends to provide extra lift. This removes the need for common space fillers while providing a sturdy base of support. With this jack, the hassle of dealing with drop legs, bulky blocks, or heavy bricks is a thing of the past.

Maximum Clearance - No Bent Tubes, Snags, or Hang-ups

Ultimate Jack Fully Retracted

The Ultimate Trailer Jack has a compact profile that allows the jack to remain flush with the trailer frame when it's retracted. This prevents the jack from catching on uneven terrain while you tow, protecting both the jack and the trailer from damage. No longer do you have to worry about bending a jack on a back road or in an unmaintained parking lot.

Oftentimes, damage from snags and hang-ups occurs because the jack isn't fully retracted. It can be difficult to see if a standard jack is fully retracted because only the inner tube extends down for use. This means that the height of the visible portion of the jack, which sits above the trailer frame, doesn't change when the jack is extended. As a result, it can be easy to overlook whether or not the jack is still extended.

The Ultimate Trailer Jack offers a simple solution for this. If the jack is raised above the trailer frame, it is in the stowed position. If the outer tube is not visible above the trailer frame, then you know that the jack is still in the support position, and it must be retracted and raised before you can hit the road.

Fast, Easy Setup with No Blocks, Bricks, or Drop Leg

Ultimate Trailer Jack Mounting Bracket

Once you have arrived at your destination, setting up is a breeze with the quick-release jack tube on the Ultimate Trailer Jack. Dropping the outer tube will give you up to 12" of lift to ensure solid contact with the ground. The ability to drop the jack tube removes the need for space fillers like blocks, bricks, or a drop leg when using the jack.

The outer tube also provides a sturdy alternative to a standard drop leg. Traditional drop legs average about 1-3/4" in diameter. But the outer tube of this jack measures 2-1/4" in diameter. The result is a base that is far sturdier and more stable than that of a standard drop leg jack.

Ultimate Trailer Jack Outer Tube Drop Extended

On a standard drop leg jack, the release pin is tucked away under the trailer frame. The release pin on this jack is conveniently located right above the mount for easy access. In addition, the pin on this jack is spring-loaded so that you don't have to remove the pin to drop the tube. Instead, just remove the clip from the quick-release pin and grab the built-in, easy-to-grip handle. With a firm grip on the jack post, pull on the pin handle and then rotate it 180 degrees. Lower the post to the desired position and rotate the pin handle back to lock the outer tube in place.

Ultimate Trailer Jack Full Extension Support

Once you've dropped the jack tube into the desired position, you can get up to an additional 15-1/2" of lift by cranking the jack. When you are 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 up into the mount so that the bottom is flush with your trailer's frame.

To maximize stability, outfit the jack with an industry-standard footplate (included) or caster (sold separately).

Smooth, Low-Friction Operation

The jack screw of the Ultimate Trailer Jack is built with ball bearings that roll smoothly along the threads of the screw shaft and the nut. This eliminates direct surface-to-surface contact within the screw. This produces far less friction along the threads, leading to a reduction in heat and wear, as well as noise. The overall result is a jack that can be raised and lowered faster, smoother and more efficiently, and with less effort.

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 product worked excellent for my needs and is as advertised. It has a nice finish and works smooth. When matched with a foot plate JF-100-ZBK, it provides a low profile while in transit. A couple things to note: the extension tube is 2” OD, the main body is 2 1/4”, and the mount tube is 2 3/4”. While the mount has a slotted holes for mounting to existing holes, my pattern of 3” center hole to hole (1.73” circumcircle radius), was about the minimum as a socket did not have space on a bolt head and an end wrench was required to tighten them; anything less will likely require drilling new holes. Lastly, the Jack has fine threads that raise and lower slowly, but is negated by maximizing the extend ability with quick pin.

Its structure and finish have held up well

I have been looking for some solution to my tailgate hitting my jack for a while. The solutions of a swing out jack don't work well for me as it would have to be too far off center for my comfort and on the outside of the tongue due to the breakaway box and spare tire. Found this and my dreams were fulfilled. Installed in minutes in place of my original jack. Easy to use, an excellent tool!

Still great! I occasionally lube the slide and pin with dry lube. Best manual trailer jack I have ever owned.

Great jack, solid build. A little disappointed that the center post has started to rust in less than a year and, because of covid, we haven't even taken the trailer out of the driveway since the jack was installed. But it works as advertised and eliminated the low-hanging jack issue.

- 322-RDJ-2K

The jack was a great addition to my camper. It provides an efficient setup, takedown and maximum ground while traveling. No longer have to worry about hitting the jack when maneuvering in driveways.

The jack continues to work out as well as it did a year ago. Makes camping easier.
Denis B - 03/25/2021

Bought this jack to replace the traditional hand crank jack. Put on a 6' x 12' cargo trailer. What I like is the ability to move the entire jack tube up and down to quickly get to the correct distance, then use the hand crank to go the final distance. Smart design and easy to install. I purchased the mating flat detachable foot plate. It attaches and easily and is easy to remove. I would definitely recommend this jack to others.

1 year later and no issues with Jack. Trailer has set out through Midwestern snow and rain and still work great.

Very happy with the trailer jack. Lots of adjustability, lets me lower the tailgate of my tow vehicle without unhooking trailer. Tube is larger than a typical trailer Jack so get appropriate sized wheel/foot.

Works great, a significant improvement over a standard jack. Highly recommended.
Joe O - 07/24/2021

- 322-RDJ-2K

Great solution all the way around. Can be fully retracted to have the best possible ground clearance while towing. Can be lowered to give max clearance to the tailgate of the truck when you want to open the tailgate with the trailer attached. And it minimizes the amount of hand cranking required to lift your coupler off the ball because you lower the outer tube assembly as low as possible before you start hand cranking. This jack solves all the problems elegantly and simply.

- 322-RDJ-2K

Very pleased with this jack. It fit perfectly to replace old jack. It works exactly like advertised. Will buy again as needed. Great product.

- 322-RDJ-2K

First off, let me say that this is exactly what I needed and was looking for. My trailer hangs low at the tongue and my last trailer jack caught the ground on the bad forest road I was driving. This trailer jack will definitely not have that problem. It goes all the way up to the trailer tongue when you retract it both ways. It also solved the problem I had of the trailer jack not going high enough to hook it up to my truck's hitch. So, this will solve both problems. The only reason I give it four stars is because it wobbles. The same mechanism that solves my two problems also allows it to wobble (the stand in the sleeve) and so as I walk in my trailer, it has a little shimmy because of the jack. I realize I can't have my cake and eat it too, but I just wanted to make others aware of this issue. Also, my trailer had the direct bolt holes and I didn't have any issues installing it, as the video suggested that I might.

This etrailer Ultimate Trailer Jack is the next best thing since sliced bread !! Direct replacement from my cheap crank jack that came with my enclosed trailer. Easy to use and install and now my tailgate can lower all the way without damage due to clearance issues with the other jack. I would highly recommend this product and this Company

- 322-RDJ-2K

Performed exactly how it was advertised. Makes getting into the bed of my truck simple when trailer is attached. Old jack would not let tails gate to open all the way. It also eliminates the need to carry multiple blocks of wood to accolade terrain where I was dropping trailer.

- 322-RDJ-2K

Very well built and sturdy; easy to bolt on to the trailer. Mechanism to adjust the jack up & down is also sturdy and seems well engineered to last. Very smooth and easy crank action. Real pleased with this item and purchase!

Still great!

Installs easily and makes it easy to quickly lift and stow. The only downside is that when stowed there a lot of rattle.

This trailer jack is great. It is very easy to jack up and down, and you change the height of the jack by removing the pin and resetting it to ant height.

I love the jack . I can lower my tail gate with out it hitting my tail gate with the trailer when it’s hooked up . Also raises and lowers lot easier and faster than the factory one . The shipping was not so good however . I paid for 3 day shipping and it took 6 days . I wanted it for the weekend so I would not have to connect and disconnect my trailer because of the tailgate problem . Sill a excellent jack .

This trailer jack has been worth every penny I paid for it. I highly recommend it to anyone who needs a great trailer jack.

Works great after one year

Exactly what I needed!!! This jack is so slick!! I have a 1985 Casita travel trailer and this is the best screw jack you could put on this trailer. The original jack hung down 8 inches and would drag on the slightest dip or incline. The new jack hangs down about 1 inch below the "A" frame rails!!!

- 322-RDJ-2K

Installed it today and it was super easy. Took me 5min tops. The quality is outstanding. Smooth action of raising and lowering the trailer hitch. Much better.

A year later and its still works great. Stays in the elements, but still looks new and still works like new. The adjustable height is great when switching between my raised Jeep and my wifes stock Grand Cherokee. You wont regret buying this trailer jack.

The ultimate A-frame trailer jack installation was straight forward. I did have to run out to auto parts store to buy a small tube of thread locker as per the instructions. I like the concept of the pull pin for quick adjustments. I added the JC-102, removable 6" caster wheel and so far the combination is working very well.

- 322-RDJ-2K

Fantastic trailer jack for the money, exactly what I needed.

- 322-RDJ-2K

This Jack has been a huge success in operations. Such a "tailgate" saver. Once installed the first one, decided to replace 4 others. Every trailer I own from now on will have this Jack.

- 322-RDJ-2K

Bought a new trailer and the manufacturer's jack was so high that when you open the truck tail gate it would hit the jack. This new jack solved that problem. Totally adjustable height, and can even be removed if needed. Fantastic fix. My truck says, "Thanks etrailer".

- 322-RDJ-2K

Install was a snap! The mechanism is easy to crank and quick. I really like 28 inch lift. Better for my back! Thanks for everything. You have gained a new customer!

  • Can Ultimate Trailer Jack # 322-RDJ-2K Be Mounted with Handle Facing Other Directions
    With the Ultimate Trailer Jack # 322-RDJ-2K you can mount the mounting flange with the adjustment handle so that it points to the side instead of to the rear if needed. So if you have a toolbox that would interfere with it facing towards the rear of the trailer you can spin it to face the side.

  • How Far Out Does the Pin on the Ultimate Trailer Jack # 322-RDJ-2K Stick Out
    I went out to the warehouse and found that the distance from the center of the jack to the furthest part of the adjustment pin on the Ultimate Trailer Jack # 322-RDJ-2K when it is pulled out is 5-3/8". If you have this much room from the center of your current jack to your winch then this is a great option for you!
