First I would like to compliment the excellent customer service received upon ordering. Now to the product- The electric jack with a 4000 lb. rating came in tip top condition with-in two business days. Was a total breeze to install, maybe 30 minutes. The quality of the jack seems very well made and upon operation lifted our BBQ concession trailer effortlessly. We opted to install a 7 way connector so the unit could be operated off the tow vehicle rather then an external battery. This connector is well made durable plastic and was also a breeze to connect. The units wiring is 10 gauge wire (2) blk. ground and red power. Very pleased with the entire set up. 228519

What can u say about etrailer I've been using u guys for years great service, easy to use web site Just a awesome company period. Presently purchased a electric jack that I will put on a 7 ton trailer that we hook and unhook a few times day I'm sure this will speed up the process thx again gang 605489

They work great at first. But after about 6 months we experienced what seems like slipping gears. 595026

- UF38-944016

Great product! 484247

- UF38-944016

I haven't used it yet, but it will be good because it has a light and a grease fitting to grease the tube when it needs it. It also has a great way of jacking it up if the electricity fails with the socket and the use of a rachet. 385711

- UF38-944016

works very well, well built and excellent durability 363511

- UF38-944016

Great product, easy to install. Sure beats hand cranking a manual jack. My shoulder and elbow love it! 343088

- UF38-944016

The grease fitting backed out and was sheared off on the second use of the jack. Fortunately, I had one to fix it with. Other than that, it functions fine. 309568

Received the new 4002 earlier than expected. It shipped well and was securely packaged. I had no trouble installing the unit and it performed flawlessly. Thanks for steering me to an excellent replacement unit. 213477

Fantastic jack! Strong motor, excellent lights, easy to install and operate. 156756

- UF38-944016

Easily installed. Jack works as advert ised. 146000

The jack still works just fine. At one point I thought In had a problem with the switch It turns out the nut came off that holds the switch in place. Luckily I found the nut at the bas of the jack and was able to put the nut back on.

- UF38-944016

Received item quickly. etrailer upgraded shipping for me with no additional charge. Haven't had chance to put jack on trailer yet due to time. I did inspect the items. Package for jack was slightly damaged but I expected that with the weight of the jack. Box that both Lynx leveling kit, covers, and jack came in was not damaged. Will be putting jack on this weekend to give it a full try. 106664

- UF38-944016

I just installed the Tongue Jack last weekend. The install was very simple although I added a simple anti-theft device in the form of a kill switch. I placed a switch inside my trailer that allows me to disconnect the power to the jack while it is stored at my shop. Installing the jack was as simple as bolting it onto the trailer and attaching the wires! 97053

- UF38-944016

I received the product in a timely manner. The installation when without a "hitch". I tried to angle the motor head so the tail gate of my truck would come down but just wouldn't accommodate it. The only suggestion I would have to the manufacture is to integrate the fuse link with the main wire to avoid making a manual connection that might later disconnect or short out. I was a little surprised at the slow speed of the lift, but it certainly has the power to raise both my trailer and truck to install the equalizer bars. Recommend using a 4x4 crib under the foot plate just to minimize travel time or length. Overall seems to be an excellent product and service from etrailer. 71385

  • Troubleshooting Wiring Power Issue on Ultra-Fab Electric Trailer Jack
    With the LED working, but switch not functioning, on your Ultra Fab Jack # UF38-944016 it is time to run some tests. First, you may just want to run a jumper wire to bypass it to see if the motor works directly with the battery first and if so, check your wires or run new. If the motor won't work directly wired, then the motor is bad. If the motor works, then there is a wiring issue. Using a circuit tester like # PTW2993, check for power to your switch then from your switch to determine...

  • Adjustable Foot Plate Recommendation for a Ultra Fab Electric Jack part # UF38-944016
    For your Ultra Fab Electric Jack part # UF38-944016 you would want the Replacement Extendable Jack Foot # UF38-751101.

  • How To Pair a Remote with the Ultra-Fab Phoenix Electric Trailer Jack
    If you have a remote for your jack then you actually have the Phoenix Electric Trailer Jack part # UF38-944055, not the Ultra-Fab Electric A-Frame Jack part # UF38-944016. That said, I am having trouble determining what you mean by the pin number or why you would need that and I did run this by Ultra-Fab as well. If you have the remote and it is not working then you first need to check the battery but then re-pairing would be a good option as well. I have attached the re-pairing procedure...

  • What is the Lift Capacity of Ultra-Fab A-Frame Powered Trailer Jack Rated for 4,000 Pounds
    The lift capacity of Ultra-Fab trailer jack # UF38-944016 is 4,000 pounds. If you are right at 4,000 pounds or slightly lower then I recommend stepping up to a higher capacity jack. The highest capacity A-frame mount powered jack we have is going to be 4,500 pounds, # HT87247, for the Husky Brute. Going with a higher capacity will make it easier on the jack which will help it to last longer.

  • Ultra-Fab Electric A-Frame Jack # UF38-944016 for 2009 Keystone Outback Toy Hauler
    According to the information I was able to find, the Ultra-Fab Electric A-Frame Jack you referenced, part # UF38-944016 would be a good choice for the Keystone Outback Toy Hauler you mentioned. The jack has a 3500 lb lift capacity, which is plenty for the listed tongue weight of the toy hauler, plus anything stowed on it. Among the many features of this jack, I like the fact that is uses LED lamps for long life as well as the fact that a 9/16 inch socket wrench can be used in an emergency...

  • Manual Crank Recommendation for an Ultra Fab Powered A-Frame Jack
    For your jack you would need just the correct size socket and ratchet to operate the manual override of your jack. A 9/16" deep well socket will insert into end of drive collar - ratchet clockwise to retract, counterclockwise to extend.

  • Can the Ultra-Fab 4K Electric A-Frame Jack Be Powered From the Vehicle
    Yes, the Ultra-Fab Electric A-Frame Jack part # UF38-944016 can be powered from the tow vehicle's battery. I suggest simply attaching a trailer connector to the end of the power wire and extending if needed, similar to the etrailer Electric Jack with Footplate and 7-Way Plug part # EJ-3527-BBX. That said, the Ultra-Fab pulls more power than the etrailer so you really can't use the 7-way socket due to the wire gauge difference. I recommend installing part # PK11852 on the jack and part...

  • Recommended Electric Trailer Jack for 7,000 lb Car Hauler with Separate Ground Wire
    For your desired ground wire connection, my recommendation for your car hauler is the Ultra-Fab Electric A-Frame Jack w/ 2" Tubing - Drop Leg - 23-1/2" Lift - 4,000 lbs # UF38-944016. This jack will give you the weight capacity you need, a drop leg for faster lift and retraction, and LED lights for easy connection in the early morning and late evening.

  • Electric A-Frame Jack that can be Mounted Sideways to Allow Tailgate to Open
    Take a look at the Ultra-Fab Electric A-Frame Jack, # UF38-944014 with 2-1/4 inch outer tube diameter, and # UF38-944016 with 2 inch outer tube diameter. Both of these jacks could be mounted so that the motor housing is facing the front of the trailer or either side of the trailer. Mounting it to the side will give you a little over 2 inches of additional clearance. If this still isn't enough to allow the tailgate to open, it is certainly possible to have a steel plate welded further...

  • Replacement Light And Toggle Switch For Ultra-Fab Electric Jack.

  • Measurements of Replacement Drop Leg for Ultra-Fab Electric A-Frame Jack

This drop leg is a direct replacement for the Ultra-Fab Electric A-Frame Jack w/ 2" Tubing - Drop Leg # UF38-944016.

  • Lubrication Required for Stromberg Carlson JET-3500 Powered A-Frame Trailer Jack
    According to my contact, the gears of their # JET-3555 are lubricated at the time of manufacture and no further lubrication of the internal gears is necessary. The only part recommended for lubrication is the inner jack tube. I've linked you to a product demonstration video featuring the # JET-3555 powered trailer jack. If you were specifically wanting a powered trailer jack that would allow you to add grease, the Ultra-Fab 4000 lb capacity # UF38-944016 does provide a grease zerk...

  • Troubleshooting Powered Trailer Jack that Blows Fuses
    Some powered tongue jacks like Ultra-Fab # UF38-944017 use the bottom of the mounting flange as the ground connection so they will have only one wire lead, which of course connects to the battery + terminal. On a jack like their # UF38-944016 there are two wire leads, one for ground and one for hot. Since you replaced a 2500-lb-rated jack with one rated for 4500-lbs this means that the new jack's motor is going to pull more power. You will want to ensure that your trailer battery and...

  • Replacement Leg Recommendation for a Ultra-Fab Electric A-Frame Jack # UF38-944016
    Yes, the leg is the portion of the jack that goes up and down that has the footplate attached to it. Since you have a Ultra-Fab Electric A-Frame Jack # UF38-944016 the Replacement Drop Leg for Ultra-Fab Electric A-Frame Jack # UF38-752020 would be the correct part to replace your bent leg. If the inner tube of your jack is bent then I do not have a replacement part that will work for you.

  • Recommended Electric A-Frame Jack With Extended Footplate For Camper
    The Replacement Extendable Jack Foot, part # UF38-751101 will not fit the # UF38-944017 jack you have on your camper because the tubing is not the correct size. My contact at Ultra-Fab said they do not have an extendable foot for your jack. I do have a solution for you. I recommend changing out the jack for the # UF38-944016. This jack has a 4,000-lb capacity and comes with an extendable foot that adds an additional 5-1/2 inches of height.

  • Lightest Available Electric Jack with 18 Inch Lift and 3000 lb Capacity
    The Ultra-Fab # UF38-944017 meets all the criteria you mentioned. It has a 3500 lb capacity, is black in color, has an 18 inch lift and has a shipping weight of 21.07 lbs. When the weight of the packaging is subtracted, the jack weighs about 18 lbs. Although it's a few pounds heavier and costs a bit more, a 4000 lb capacity model is available as part # UF38-944016. The extra capacity would mean that your jack won't need to work as hard, which would extend the life of the jack. The...
