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.

I have a 14' utility trailer I use to transport my Yamaha Wolverine Side by Side. I tow it behind my pickup and my motorhome. It is normal for me to travel some questionable dirt roads. As a result I bent the original jack several times and actually had to replace it once. It didn't retract far enough, it left an inch or two hanging below the A-frme tongue. Sometimes a steep driveway approach would catch it and bend it. When I destroyed the replacement jack I decided it was time to look for a solution. I spent a few more bucks and got the Ultimate Trailer Jack. It retracts above the bottom of the A-frame tongue so the jack is protected. Problem solved! I recommend this trailer jack to anyone that has a clearance issue that results in dragging your trailer jack.

I put this on my dog trailer. Because this trailer gets pulled in the field and through ditches. It is the only jack I have found that allows me to do this. Not to mention the time saved hooking and unhooking the trailer by half the time screwing the jack up or down. It was a little tight at use and the spring pin was stubborn when finding the hole to snap in. But 5 minutes with a little bit bigger drill bit just to chamfer the pin holes and a dremel tool to knock a little weld slag down and it almost works automatically. Love it.

- 322-RDJ-2K

Jack is very sturdy and well made; great design. The jack would not fit well enough to attach to tri-angular structure holes made for the old jack in my nuCamp [email protected] camper, but I was able to drill one other hole and attachment was fine. Also, the spring loaded swivel-handle pin which fixes height had difficulty going into some of the pre-drilled holes of the stand. I used my Dremel tool to slightly bevel the top of the holes and the pin, itself; it now works great. I was looking for a drop down jack that would speed the setup for dropping trailer from my truck as well as allow for clearance of truck tail-gate to open without interference with the trailer-jack while trailer was attached which this jack does. I had considered a swing-up jack, but it would not fit because of welded-attached storage box for the battery and propane tank on the front portion of the trailer. After mods that I made, I am very pleased. Just what I wanted. Well worth the installation trouble I experienced.

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.

Just replaced my old trailer jack. The only way to get the trailer out of the backyard where I keep it is to drive over a curb.The old jack caught the curb and bent the tube so bad it would not jack up or down.I give this new jack 5 stars, I can raise the foot up almost 12 inches from the ground.There is no way this will hit the curb now. It is built solid and works just like it is supposed to.

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 received the jack on the date delivery was promised. I put it on the same day as received and I am pleased with it. The jack came with a small foot plate which is great if you park your trailer on a firm surface like concrete, cement, or gravel. I ordered the full-sized foot plate since my trailer is parked in the dirt. The only reason I did not give this a five is because it does not come with mounting hardware, such as blots, nuts, and washers. I think the mounting hardware should be included in the price.

Worked liked it said, 5 minutes to put on, I can lower my tailgate with the trailer connected

The Ultimate Trailer Jack is an excellent quality product. I installed it on my 2019 Wells Cargo tandem axle trailer because the original Jack had bent after scraping it on a deep dip in the road while towing the trailer behind a Class C motorhome. Because the new jack retracts up to the frame, now it won't bottom out and drag the ground. Great design!

After owning the retractable trailer jack a year, this product has worked perfectly! Great design and functionality.

The trailer jack fitted the hole pattern left by the original jack without modification. The BIG advantage of this jack is its large net range of motion. It can be lowered enough to avoid contact with the tailgate of a full sized pick-up. It can be raised enough to allow passage across uneven ground and later still extend down to keep the trailer level on a sloping site.

It has been a real winner and still moving fine despite the wet and cold weather.

Mounting holes Line up well with bolt on coupler body. Cotter pin for drop leg release bends easily and does not retain its shape. I highly recommend cutting of supplied cotter pin and replacing. Label on drop leg served as a stop and jambs it allowed to free fall. Hold drop leg then remove release pin

- 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.

I would happily give it five stars if they would have had the product capabilities listed properly. 2 in feet fit this Jack beautifully.#PS1400700340. See pictures. Love the Jack being able to move it up and down not having to screw it up and down forever or put wood underneath

Still works great

Very well made product and the adjustability is perfect for what I needed. The only issue I had was the little black plastic piece that serves as a block for complete removal of the jack is cracked and broken. But that probably happened in shipping since the box had been beaten by Mike Tyson.

I will have our customer service team reach out to you.

I love this jack! It replaced the OEM flip foot style that never raised high enough. Replaced the OEM with an electric tongue jack which seized up after a year by the Ocean ( the switch and electrics had copper plated steel contacts which corroded quickly). The Ultimate Trailer Jack is perfect. It lifts so quickly and easily. I will never drag the tongue on speed bumps or when exiting my driveway. Highly recommended.

- 322-RDJ-2K

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

Great product. Just installed on my Stealth V nose trailer and clearance is good to the nose and the 3 bolt pattern is a perfect match. This is a real time saver! And back, arm and hand saver. Your service is excellent as always. Thanks!

- 322-RDJ-2K

Solid hitch lock, fast shipping, stellar service as always. Here's to hoping it prevents my trailer from being stolen...again.

- 322-RDJ-2K

Great jack. The quick release pin to allow it to raise far away from the ground should be how every jack for a utility trailer is.

- 322-RDJ-2K

Great jack. Very convenient not to have to remember to pick up the block of wood that I had to use with the stock jack. Very simple design to lift and lower and lock in place. I drop and hook my trailer every day and it has worked flawlessly. The only thing I had to do was get a slightly longer ball mount so I could drop my tailgate when the jack was in the full up position.

- 322-RDJ-2K

I am very happy with the way this jack works. It gives much more clearance with less cranking.

- 322-RDJ-2K

etrailer is always awesome! They ship my orders out very quick, their communication is amazing, just a great company to deal with. This jack is amazing, I mounted it through an existing hole on my trailer, it was very easy to mount, and it's the best trailer jack I have ever had on a trailer.

- 322-RDJ-2K

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 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

This trailer jack is awesome. My son's 6x10 enclosed work trailer needed a new jack. Installation was easy, and it is VERY adjustable. To clear the tailgate, we drilled a hole in the footplate bolt for a hitch pin and removed the slot that aligns the jack. Now he can completely remove the jack, no tools are needed to remove and install the jack. That's theft protection! When attached and lowered, it takes a lot fewer cranks to unhitch or connect. Highly suggest this hitch for small to medium trailers.
