Ball Screw Technology

The Phoenix electric trailer jack uses ball screw technology. Instead of raising and lowering the jack with a standard Acme screw, the Phoenix incorporates a strong threaded steel rod with ball bearings. These ball bearings roll along threads between the rod and the nut, so there is no direct surface-to-surface contact between the rod and the nut. This extends the life of the electric jack by creating less friction along the threads, which leads to less heat and wear. As a result, the motor is able to operate more efficiently, leading to improved performance and increased longevity.


Manual Override Feature

An important feature with any electric jack is the manual override option. The Phoenix electric trailer jack is equipped with a 9/16" deep well socket that can be used with your electric drill to raise and lower your jack in case of a power failure. Just insert into the end of the drive collar and ratchet clockwise to retract and counterclockwise to extend.

this jack works perfectly my trailer is heavy!!! 296149

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. 289214

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. 645200

I am awaiting my 4th on that should arrive today. I have not had any good luck with this model. For some reason it will work for a bit then just quit. the warranty is the only thing that is keeping me with this product. I am hoping this next replacement will last but we shall see. 352225

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! 294153


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!

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. 703648

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. 795991

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! 759165

We got the jack installed on the trailer. So far I am happy with it. Easy to program the position memory buttons and no issues doing so. My only concern is if we have a power failure, cranking the jack by hand is next to impossible. Time will tell, with the warranty, I'm not concerned. If it fails, I will let you know! 683042

    Your Trailer Life powered jack is made by Ultra-Fab and similar to our Phoenix Electric Trailer Jack # UF38-944040. I reached out to my contact at Ultra-Fab who confirmed that if the red LED flashes for 3 seconds, a high amp situation exists and the jack will automatically turn off after that. The jack will then wait 5 seconds and then reset. This process is repeated if it continues to sense a high amp draw. Assuming your batteries are good, the most likely cause is a bad connection....

  • Could Powered A-Frame Jack be Powered From Breakaway Battery
    You would not want to connect a powered a-frame trailer jack to a breakaway battery like you mentioned. The battery would not have enough power to operate the jack.

  • 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...
