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.

Works well and is VERY fast. Strong enough to lift the back of my pickup up. (raised it a little to far when putting on my weight distribution hitch.) To make it go up or down just a little bit, press firmly and release. If you try to tap it lightly, and do it twice too fast, the jack will go ALL THE WAY in that direction. It would be very nice if it came with a weather proof cover. (No bright logo please. People would know it is a good one and might wish to steal the jack.)

After only a few uses the jack quit working. First the memory settings kept getting "forgotten". I reprogramed them twice before they quite working altogether. I kept using it without the presets but later it would not go up and down. I had to use a wrench and the provided socket to to move the jack which was much harder than expected. While I was turning the jack it started running, ripped the wrench out of my hand, and the wrench handle put a hole in my propane tank cover. The manufacture replaced the jack at no charge but would not do anything about my propane cover. After using the 2nd jack awhile in now is making clicking noises as the tongue is lowering. It sounds like maybe there is a tooth missing on one of the gears. My tongue weight is around 1400 lbs so well below the rating yet the jack does not seem to be holding up well even though it is not use all that often. Otherwise I do like the jack. It is fast and the memory presets are a nice convenience. I also like that the head is smaller than other similar units.

This is the best jack I have had (and I seem to have gone thru quite a few). It was a quick and easy install for a replacement and I have found it is the fastest jack to raise or lower my hitch. It is also one of the quietest I have ever used. Great for early morning packing and not waking up all the neighbors. :) The jack seems a lot stronger than other jacks I have used and better built with less plastic on it than most. Would definitely replace any manufacture supplied jack on a new trailer with this one again on a heartbeat!


Comments
I have had a problem with the switch on this jack. It was the first generation of the jack. I spoke with Ultrafab and they replaced the whole jack with a new one without any issue to correct the issue. I am very impressed with the Jack and especially the great customer service! Cant be beat!

Best jack out there. The fast up and down speed along with the 2-button memory makes this jack the best one out there in my opinion. Mine had 2 memory buttons (a lot of the promo material suggested only 1 memory button) so I can set one for the extended/hitching position, and a second for the fully retracted position. Thus, I never need to hold extend/retract...rather I just hit one of the memory buttons and it does the rest. Huge time saver. To set the memory on mine I hold the desired memory button and wait for the light to flash red (not green like the manual said). The drop foot is also a nice feature. I would strongly recommend this jack.

This Jack is crazy fast. Moves smooth and doesn't seem to struggle in the slightest. My only concern is that there is no positive power shut off. Im an electronics tech and ive seen touch buttons like this fail in moisture environments. This seems well built but I didn't want it moving down when driving so a simple on off switch was added. Concern solved.

Review from a similar Phoenix in Trailer Jack


The first jack we received failed in the control circuit after the first use. Ultra-Fab was very good about sending a replacement jack after some brief troubleshooting. The second jack has performed well for the past year. It hasn't struggled at all to lift our trailer and the remote is a very convenient feature... although the remote control occasionally struggles with keeping a good signal and requires pushing the buttons repeatedly.

Review from a similar Phoenix in Trailer Jack


The product we received is great but the customer service we received from etrailer.com was the best! Our original order was damaged in transit and we contacted etrailer. They immediately shipped us a new unit and supplied us with a shipping label to send the damaged unit back. They couldn't have made it any easier. Very pleased!

Review from a similar Phoenix in Trailer Jack


I purchased this product to replace one that has given me good service for several years but which I felt I was working it to close to its limits. My selection of this electric tongue jack was for it's 5500 Lb rated load capability but I do like both the remote control unit (that comes with it) as well as the Jack's face plate controls that also have a memory function for both up and down positions. I was surprised how well the unit worked with the factory memory calibration settings for my application which made the installation go much faster. While I had to run an extra 10 guage ground wire back to the battery, I like that they do this to make sure there is no possible chance of the jack motor not being properly grounded. The only reason I did not give it all 5 stars is because I reserve the highest rating until I am able to see from experience that it is warranted.

    Phoenix Electric Trailer Jack - A-Frame - 22-1/2" Lift - 4,000 lbs # UF38-944040 sounds like it needs a better ground connection.

  • Troubleshooting Wiring on Ultra Fab Electric Trailer Jack
    To test your jack, I recommend first checking your trailer battery for proper charge. The lights will require far less power than the motor, so lights may come on but you still may not have enough juice to power the motor. If the battery is not an issue, I recommend running a jump wire to your motor from the positive terminal of a 12V battery. The motor will have two 12V wires because the polarity will determine extending or retracting. If the motor functions, then you know you have...
