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.

Easy installation, reasonable price, works great! Much to my surprise, our trailer had a 2.25" top hole and a 2" bottom hole. This jack fit fine. The lights are helpful.



by:

I recieved the jack in a timely fashion and the box was destroyed (packing wasn't good) and was a bit worried but it didn't have a scratch on it and was very easy to install. Bolted right up!I really am happy with it and I would recommend it and etrailer!!



by:

Great work! Had a customer with a tight time line that Alex made certain of a timely delivery.



by:

Nice jack . Fit up on travel trailer was good did have to take 3/16 off the back of round mounting plate so it would not hit the battery box I did check with Ultra-fab and they got back to me the same day ,wanted to make sure this would not effect warranty . well built and quality was very good . So much better then my old jack .



by:

The three items we ordered arrived on time. The electric jack was easy to install, 3 bolts and 1 wire. Took less then an hour. It makes hitching and unhitching our Keystone Hideout much easier.
Customer service was very helpful when we called to add a third item to our order.
No Hassle!



by:

Easy install in 5 minutes, works great, excellent customer service, fast service and shipping. No more hand cranking for me.

Works great, fast and easy, my friend bought one from you after he saw mine



by:

Lift came super quick from etrailer. Very easy to install since replacing older model of the same lift. Ultra-Fab should include wire and fuse needed for the positive wire -had to reuse old fuse!



by:

Easy ordering, good tech support. Fast shipping. 30 minute install. Works great. Would recommend this item.

Working very good. Have only used it about 6 times so far. Great product.



by:

The fit was flawless and it handles my Flagstaff Mac with ease. It is a pop-up and not a huge load, but it saves a 70 yr. old a lot of cranking. Install was a breeze. Love it when items are as described. 6 day delivery over a holiday long week-end. Thanks for the great service.



by:

Easy to install. I also replaced bolts with grade 8 bolts.
Ultra fab is a good product.



by:

Excellent figment and easy installation!



by:

etrailer had the best price. Shipped to me in a few days. Took about 1 hour to convert from the 4th bad liepert smart jack. Works fast and easy. As I read on other reviews it is "wobbly" side to side compared to the old jack but rating are equal.
Put on my enclosed ATC car trailer. Have not yet loaded the car - I think that should only be done when "hooked up". Check with me in a few months after I have used it a bunch.

doing fine

The Ultra-Fab power jack is great so far. This was a direct replacement for the stock original jack. Easy to install. This one has a fuse in-line as the original jack did not. I like that feature.

AOK



by:

Unit was out of stock but I was willing to wait. Well it was delivered a lot sooner than I thought and was kept updated about delivery date.(no guessing). The jack installed easily and works as expected. I am very satisfied with the service and the product. Thank you etrailer!

Used the electric jack this past weekend. Really like it, glad we got it. Very easy to install. Will recommend this product to anyone wanting a easier way to hook up your TT.

Bought this one year ago and it died already. It is not one that I would recommend. We had to hand crank on several occasions. We bought something different and threw this one away. As for Etrailer, great company.



by:

Well I guess its been a year since purchasing the Ultra-Fab Electric A-Frame Jack as per the email I received from etrailer. I have been very happy with the purchase, this is so much better than cranking a handle!! Installation was very easy too. I liked this one since it has a zerk fitting for lubing the jack where others didn't seem to have that. All in all, I would purchase this jack again and through etrailer.com too.



by:

Worked as advertised. Easy installatio n.



by:

easy to install and one wire to connect. works great so far on my Pace American V-nose enclosed trailer with a couple snowmobiles on board

Russ

Very good, recently sold this trailer



by:

The product was easy to install. I put the trailer on my truck hitch before I started. No need for impact tool to loosen the bolts on the manual jack. Your jack fit fine, even cleared the propane bottle cover, although I have to sqeeze a little to get to the light switch. My trailer is a 30' Keystone Hornet with slideout. Your jack sounded like it was working hard, but it kept raising. It's the 3500 lb model, and I didn't measure the tongue weight before I started. However, it was right at freezing outside, and my battery isn't new, but all went well. Plenty of travel, and I like the removeable foot. All in all, I'm a Happy Camper.



by:

Great product, was easy to install and wire up. Very durable, grease tip location on the tube very convenient. Cons ( would like to see a foot extension for the tube and a more durable cover for the grease tip, other than that its a thumps up for this product.



by:

Installs easily, works great. Be careful to shut off the up/down switch as soon as the jack reaches the end of its travel, otherwise you will blow a fuse.

Dick W.

7/26/2020

Wonderful. Easy for the grandson to blow the fuse, but that is why the fuse is there.



by:

Great jack - haven't hooked up the electronics, but it's been great. The little rubber cover over the manual jack nut drive cracked, but I assume that is because I keep using it repeatedly (more than it was designed for). I wish it had a zerk fitting or two on the jack tube, just to keep it from seizing up in the future.



by:

Low price but high quality. Works faster than most Jack's out there. My only concern is the length of the shaft. I need to use a 6 inch block under it. Works great. I now have 2 of them. One on my enclosed cargo trailer and one on my 26 ft travel trailer. Highly recommend. It



by:

My husband is very happy with this electric lift. It certainly saves his shoulder!

    The outer tube diameter of the Ultra-Fab Electric A-Frame Jack, part # UF38-944017, measures 2 inches, and the mounting holes that are used to attach the plate of the jack fit 2 inch or 2-1/4 inch spacing.

  • Could Ultra Fab Jack part # UF38-944017 be Used on 3,600 lb Trailer
    When picking out a trailer jack the capacity the jack has is for the tongue weight of the trailer. So the Ultra Fab jack part # UF38-944017 that you referenced could lift a vertical weight of 3,500 lb which would be way more than you'd need for a 3,600 lb trailer that would have a tongue weight of around 360 lbs. Having more lifting capacity just means that the jack won't strain when operating.

  • Does the 20 Amp Circuit Breaker for Ultra-Fab Powered Trailer Jacks Reset Itself
    Once an overload condition has ceased then the circuit breaker should reset itself. It is mounted on the outside of jack # UF38-944017 but should not need any persuasion to reset. If the jack is not powering on it could be that an overload or short still exists or something else in the electrical system from the power source to the jack is not working properly. You will also need to check the in line fuse. If it is blown the jack will not operate. If all the wiring is done correctly and...

  • Ultra-Fab Electric A-Frame Jack Motor Spins But Leg Will Not Move
    I am sorry to hear about the issues you are having with the Ultra-Fab Electric A-Frame Jack part # UF38-944017. Unfortunately, it sounds like there is internal damage to either the threaded rod or bevel gears. The gears and or threaded rod are not replaceable parts therefore your only option is to replace the entire jack. I know this may not be what you are looking to do but it is truly your only option. For replacement, the Electric Jack w/ Footplate part # EJ-3520-BBX would work well.

  • Where is Fuse for Ultra-Fab UF38-944017 3500 lb A-Frame Trailer Jack Located
    The 30 amp fuse is installed in a black cylinder shaped fuse holder that should be installed inline on the red wire that attaches the Ultra-Fab # UF38-944017 3500 lb powered A-Frame jack to a 12V power source. Simply unscrew the fuse holder, remove the blown fuse and install the # UF38-751034 replacement. The holder could be installed anywhere along the line between the jack and the battery, usually right at the battery. In case you no longer have them, I've linked you to a .pdf copy of...

  • Troubleshooting Powered Trailer Jack that Doesn't Always Power Up and Down
    Make sure the main ground wire on your trailer harness is connected to a clean metal surface of your trailer frame.

By improving the ground of your trailer harness the jack should start to function normally again.

    I have a few different options for you and it all depends on what you're wanting out of a trailer jack for your 2017 Forest River Rockwood Signature Ultra Lite 2703WS. The absolute best clearance you'll get is with the Trailer Valet JXC Trailer Jack w/ Footplate # TV94FR because it uses a hand crank, but then you can use your drill then you want it to operate faster. Using this means you don't have to make connections to your trailer battery plus you won't have the trailer jack motor...

    On the Ultra-Fab trailer jack # UF38-944017 the in line fuse holder will be cut in half and spliced in along the power wire. Ultra-Fab makes the following statement: The Fuse Holder can be installed by means of either crimping or soldering the connections.

The most important thing to check is to ensure that the opening for the jack on the trailer is large enough for the new jack. The Bulldog Jack has an outer tube dimension of 2-1/4".

  • Can an Ultra-Fab Electric Trailer Jack that has Been Over Extended be Repaired
    The way that the electric trailer jack # UF38-944017 works is using an ACME screw and a nut. The nut is fixed and the screw goes up and down in the nut. At the end of the screw the metal is twisted, smashed, or otherwise purposely cross threaded to prevent the screw from just coming out and the load dropping. If you try to raise a jack with this type of design too far it damages that nut and the screw. Those parts cannot be replaced. You will need to replace the whole jack. This is not...
