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 was so happy to receive this unique jack, which can be raised high or conversely, be lowered to the ground merely by releasing a safety clip and pin. It's exceptional, as it can be raised to allow sufficient ground clearance while trading. It was reasonably priced and seems quite well-built for the money. This type of trailer jack is not readily available at many places, I've found. I had also kept my swing-away jack on the side of the a-frame just in case I need it, rather than popping off the o ring and eliminating the extra jack. It may come in handy for those occasions whereupon I might need to add the castor wheel to the adjustable center a-frame trailer jack. Be extra careful and vigilant with this adjustment center a-frame trailer jack as you need to be mindful of the pinch points, being that it's adjustable. Other than that, I am exceptionally pleased with this rare find.


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.

This hitch is rock solid. My sons work trailer is maxed out as far as hitch weight and this jack is holding up very well. He likes that the crank does not interfere with the tailgate. Its well-made and have had no issues with jack.

this jack thinggee works really well. It solved my problem of not having enough room to attach the wheel when unhitching the camper. although, the bolt holes did not line up exactly, my handyman was able to make it work to attach this device.


Wonderful versatility with the superior adjustability. The added height adjustment allows you to level your trailer without adding blocks, rocks, wood slabs, etc. (be sure to chock your wheels, of course). I replaced an aging stock trailer hitch jack with this. Great investment!

After a year, I still think this is the way a trailer jack should be made. Anything else is a compromise.
BA78 - 10/05/2022


Product exactly as described and speedy delivery. It will be a great addition to my trailer as I've used this jack before, no more dents in the tailgate. Great purchase!

Works great. Now I can lower the jack and open the tailgate without damage.

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.


Great drop foot! However I need a heavier jack for my dump trailer, 10k rated dump trailer. Thinking of an electric with a drop foot. Suggestion?

We do have some options for electric jacks with the capacity of over 10K. The first would be a landing gear set like part # UF17-943010
Ultra-Fab Deluxe Electric Landing Gear Set - 38" Lift - 12,000 lbs
. It would be welded on and is typically used in RV applications. Another option would be part # BD185400
Bulldog Velocity Series Electric Landing Gear Jack - with Remote - 24" Lift - 12,000 lbs
, which is a more expensive option however it is a very solid jack. Beyond that most of the 10K jacks that we carry are non-electric jacks. If you are interested in them, please let me know.

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.


Installed easy and seems to be well-built. I like that it pulls up nearly flush with the frame of the trailer.

Still using it and still recommend it. I use the trailer to carry my UTV and need as much ground clearance as possible. This is the best solution.

This trailer jack is well designed and manufactured. Shipping was prompt. The jack is sturdy as well as having the advantage that it can be positioned so that nothing protrudes below the A-frame, yet s 90 degree rotation of a handle allows the outer jack to drop to any of a number of positions, then the inner jack is extended using the crank as with lesser tongue jacks. The quality is impressive.


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.


I hitch and unhitch my job trailer sometimes several times daily. This has been a fantastic improvement and really speeds things up. Only complaint is that it is quite loose in the fitment of all the moving parts, allowing it to wobble a lot. I have to try to stay out of the trailer (or at least lower it as far as I can) when it's not hooked to the truck.
Bonus is that I originally got it to allow me to lower my tailgate, as my trailer tongue is very short. It definitely makes that much nicer!


The function in this jack is unique and incredibly useful. I made the right choice to change the one I had to this. That said and as a mechanical engineer, I'd change a few things about it. Aligning the holes to the height-adjustment pin is much more cumbersome than I anticipated. I suspect this could be improved with some component design revision and at effectively no production cost change. The other nuisance is that the product label was applied to the sliding post and is enough to impede the motion to reach the top height hole. In production I'd just put that on the fixed mounting base to eliminate that condition. I can remove that label, but not without chemicals and time that I haven't put forth yet.


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


Great concept. Good quality, fairly robust. Certainly a time & arm saver.
My disappointment was the looseness / clearance between the holding collar and the outer sleeve of the jack mechanism.

025"+ allow the jack to move around within the collar while raised & towing - which will inevitably lead to parts wearing, noises, and increasing looseness over time.

Perhaps a bungee cord securing the top part while towing will suffice.


Works great, much better and quicker than the one which came with trailer.

Works great, great time saver. Well worth the price.
Gary - 11/18/2022


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.
Wyatt - 04/16/2021


This is a must if you work out of your truck while you have a trailer attached!
You can open your tailgate and not hit the other jacks.
Very easy to operate. A+


Excellent jack it fits my needs perfectly cause of the uneven areas i go thru with my trailer .by being able to to tuck away or raise up. your chances of it being ripped off are eliminated.
Up and out of the way is a great feature to have in a jack and will purchase more as needed i love it and how it functions well thought out. Thank you


I purchased one of these Trailer Jack -A-Frame before. Very Handy to have. A fantastic invention for a trailer jack.


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
Kam - 04/14/2021


The surge brake on my Travel Trailer prevented installation of this jack. Turning it 120 degrees to either side did not help as the baseplate now extended too far from the tube and overlapped the brake mountings. Enlarging the mounting holes on top & bottom of the tongue would have been necessary as well.


I had a fairly difficult time installing this item as a replacement. The 27 1/2" lift is misleading since it takes a jack stand or blocks to reset the center post, and the starting point is ground zero, however the 27 1/2" can be achieved. The jack or the trailer frame was not properly square with one another requiring shimming of the 3/8' A=frame bolts to prevent binding of the assembly when trying to place it in any of the 2" spaced positions.


I really like the fact I can open my tailgate fully. The only issue I have is that sometime while adjusting it, it sticks. Other than that you won’t be sorry.
