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've had this power jack for about a year and it works flawlessly, it beats hand cranking. And not to mention the great service from etrailer their the best in the business.
by: Walt Z03/28/2015
Bought Pro Series Weight Dist Hitch, Jameson C was very helpful picking the right one out , ordered it on Friday and it arrived on Wednesday a day earlier than expected. Placed a second order for an electric jack and misc. parts. Extremely happy with their service. I don't review stuff but these guys deserve one.
by: George 08/17/2023
Great item. This is my third power tongue jack since purchasing my RV 23 years ago.
Hopefully this jack will emulate its two proceeding cousins.
by: CESDewar04/08/2017
Extremely pleased with this purchase. The jack was very easy to install - took less than 10 minutes to remove the old jack and insert this new one which fit perfectly. Assuming it lasts (and I have no reason to think it won't as it looks well-constructed), it will prove to be a very nice addition to my camper as it was quite some effort to lift it up enough to get the weight distribution hitch spring bars into position. I like that there is an easily accessible nut for manual operation, and a grease point. I bought the cover for it to keep out the elements.

A year later it continues to work flawlessly - have not had a single problem with it of any kind and continue to find it a pleasure to use. Very happy with this purchase.
by: Jason Carmichael 06/27/2015
Replaced a Canadian made clone that failed after 11 uses. Sounds completely different when using. 2 year warranty, available 5 year seems too good to be true. No idea what the difference is between this one and the 158 one. Nice thick 12 gauge power wires look and work as expected. Not that big of a deal, but wish the 7 way had a 4 way piggy back plug. 9.5 out of 10.
Used on my 6x12 utility trailer, probably has 1500 lbs lift, so practically nothing to the motor. Used 2 times a week during mowing season.

Simply works
by: George06/13/2018
The electric A FRAME jack with the 7 -Way Plug is the second one that I ordered.The unit is most helpful as it has the electric hook up to the plug in and do not require an extra battery. Very quick to install.I would recommended that you include with the star locking washers 3 new mounting bolts. When removing one of the original mounting bolts it broke.

I liked the first one so much that I purchase another one for my other trailer
by: John B06/24/2015
The Ultra Fab 3502-7 went on my 6x12 enclosed trailer with ease and the bolt pattern matched perfectly. The speed seems to be fine and the footpad is bigger than the one on my old jack. The price was way cheaper than anything else comparable that I found on the market.

My jack is still working perfectly. Cant imagine not having this great product.
by: Johanne K07/23/2017
The Jack works great. However there is no documentation as to how much current draw it uses and I was frequently blowing fuses. I finally replaced and in-line fuse with a self setting circuit breaker and I never had a problem after that. Also after just a short time the lights on exterior stopped working.

I have sold the camper, the last I knew it was working great
by: Dick 09/10/2022
My previous electric jack shorted out while I was not home, and my battery exploded. I specifically bought this jack to plug it in when ready to use. A little inconvient, but worth the peace of mind. I have to have my engine running in order to operate the jack. Not true for all towing vehicles.
by: Steve Hanson05/14/2016
Great product, and great value. I do not expect to have any trouble with this electric jack. By having a jack that runs off the trailer plug on my truck, I will never have the chance of damaging the jack motor due to powering a jack off a battery with less than 12 volts. I installed this on a 26ft camp trailer that was difficult to manually raise or lower due to a back injury....now I can enjoy camping again.
by: Tom M.10/23/2016
Great product. The only problem I've had is, if you raise the jack, say after hitching up, and then hit raise instead of lower, the fuse in my vehicle blows. If the jack is already topped or bottomed out and you try to go in the wrong direction the fuse for the trailer lights blows. So I just make sure I leave some room in either direction.
Jack was very easy to install, and combined with the eTrailer hitch camera life is much easier.
by: Ken06/21/2016
Bolted right on. No issues. Worked as advertised.
I bought one like it about 6 years ago and I use it about twice a week. The old one was making a horrible sound so I bought the new one. Replaced it before I got stranded with the old one.

After a year, the jack is still working. I suspect it will last several more years.
by: Gg06/22/2020
We had problems getting the electrical plug to work with our truck. Used the manual crank on the top to raise and lower it. We worn that part out so had to order another jack. Wired it to the trailer battery directly with an in-line fuse and it has worked perfectly since.
by: Joshua12/21/2017
The jack works really well! There was an issue with the first one I received being damaged in shipping but etrailer spoke directly with the manufacturer where it was drop shipped from and they immediately sent a new jack. Wonderful customer service from etrailer and Ultra-fab.
by: Bill B01/16/2017
This powered jack works great on my 6x12 enclosed trailer. i have the trailer loaded down with tools and this jack handles the load well. In the past year I have used the jack multiple time a week and never have had an issue. This is a great product for a fair price compared to others.
by: Tim W.10/10/2016
What I appreciate most about this purchase is the helpful and complete website @ etrailer.com that let me compare various makes and models and learn just which unit to buy. I'm no idiot, but at the same time I didn't exit the womb with complete knowledge of which electric jack to buy.
Because I use a load-leveling hitch, I need to take the weight off the trailer tongue and lift the weight off my truck's frame. For this reason, I bought the highest-rated (in pounds) lift that would fit my 2" mounting hole.
The "Ultra-Fab Electric A-Frame Jack w/ 7-Way Plug - 18" Lift - 3,500 lbs" installed in about 20 minutes and lifts my 20' camper tongue beautifully. Since it's October in VT and the leaves are already turning, I won't have much time to test it before winter, but the early results are simply perfect.
Finally, the price was competitive, the shipping was free, and the shipping was fast. I have come to appreciate etrailer.com as a vendor.
by: Diana Allen04/26/2015
Being a 71 year old grandmother and travel the festival circuit, I needed this electric jack, I needed something to help me unhitch my truck from my travel trailer, this electric jack was just the answer, it was so easy and a big time saver.
by: Mike06/13/2016
This makes me feel I have been in the dark ages too long. Time after time, I have bent over (with plates and screws in my back) and jack my trailer up and even turning forever to get the leg down. Now, I press button and it is done for me. I have spent more money on a lousy family dinner at a restaurant than this cost. So I ask myself, "What were you thinking?"
I have needed this for a very long time. This even has a 7/way plug! No external battery required...duh.
by: Brian J.09/11/2016
Very easy install and functions as advertised, a lot easier than the old hand crank I had before. Thanks for a great product at a great price!

The Ultra-Fab Electric A-Frame Jack w/ 7-Way Plug - 18" Lift - 3,500 lbs works just fine. Been using it a year now. Works great. Beats cranking by hand.
by: thom w07/13/2017
Glad to have it. EASY installation. Going camping this weekend to try it out, on my 18 foot camper trailer. Nice to not have to do all the hand cranking. Suggested the package include new bolts, rather then requiring use of old bolts. Awesome to just plug it into my vehicle and raise and lower. Nice feature having lights. I recommend it at this time.
by: John J.09/07/2016
This has been a great back saver, was very easy to install, and use. Used the manual jack one time, and decided to replace with electric jack. Especially while traveling, if you have to disconnect and rehook up the trailer.
by: Tom R.03/20/2015
Wow! What wonderful quick service! We received the Jack and it worked exactly as expected. The installation was quick and easy. My only concern is that the foot hangs down lower than my previous jack foot. I will be putting a spacer in between the jack and the tongue to be sure my wonderful jack is not damaged by dragging when I go through dips. If you want an easy way to adjust a jack, this is definitely the way to go! I even had to run out in the dark last night and turn on the light to see what it would do. It lights all the items I would need to check or work with at the front of the trailer. I can see the battery, the propane, and the hitch. I love that.

- Troubleshooting An Ultra-Fab Electric Trailer Jack That Just Keeps Blinking Typically if an Ultra-Fab electric trailer jack is just blinking it indicates that the power source isn't enough to fully operate. Have you checked the voltage running to the to jack with a multimeter # PT89ZR to ensure it's getting a full 12 volts? A fuse is going to blow to protect the jack's circuit board but doesn't always come included. You could use an inline fuse holder # SWC9538 to properly protect your jack. You will need to look at the amperage pull to determine the correct...
view full answer... - Will a Powered Jack Replace a Swivel Jack?You could potentially use a powered jack to replace your swivel jack if it was an A-frame jack. There are jacks available with weight capacities between 1,400 lbs and 5,000 lbs as well as lift heights between 18 and 25-1/8 inches. For example, the Ultra-Fab # UF38-944037 gives an 18 inch lift and has a 3,500 lb capacity. I've added a link to each of your electric A-frame jacks for you to take a look at.
view full answer... - What Does Ultra-Fab Electric A-Frame Jack Use as Manual CrankWhile we don't carry a replacement manual crank for the Ultra Fab Trailer jack part # UF38-944037 all you need is a 9/16 inch deep well socket as that's what the included tool is.
view full answer... - What Size Battery Should be Used to Power Bulldog Electric A-Frame Trailer JacksA standard car battery will work to power Bulldog trailer jack # BD500199. The battery will need to have an amp hour rating greater than 30 amps which is the max current draw of most electric A-frame jacks. Other option is to use jack # 3370093500 or # UF38-944037 provided your tow vehicle has a 7-Way trailer connector with functioning 12 volt circuit. Both of these jacks are powered through the 7-Way so no battery is required on the trailer to run the jack. I have linked videos for all...

The 12 volt circuit would just have to be rated high enough for the power draw of the electric jack. And you will probably want to have the vehicle running so the alternator can help with the power demands. This jack draws 30 amps when under load. Most tow packages will have the 12...
view full answer... - Installing the Ultra-Fab Electric A-Frame Trailer Jack # 38-944017The Ultra-Fab Electric A-Frame Jack - 18" Lift - 3,500 lbs # UF38-944017 can be wired for both the power and a ground to go to the battery, you would just need to add the jumper wire for the ground connection as it is designed to be grounded to the trailer through the mounting flange. The # UF38-944037 has a 7-way plug to power the unit so no other power is needed if you prefer.
view full answer... - Ultra Fab Powered A-Frame Jack Recommendation that Gets Powered by Trailer BatteryThe Ultra-Fab Electric A-Frame Jack # UF38-944037 is set up to be plugged into a vehicle 7-way whenever it is needed to power the jack. For basically the same jack that would be set up for wiring to a trailer battery you would want the part # UF38-944017 instead. This jack grounds through the mounting hardware and gets powered by the one black wire of the jack that would get run to your battery. Check out the install video I attached for more info.
view full answer... - What Size Battery Should be Used to Power an Ultra-Fab Electric A-Frame Trailer JackThe 3500 pound Ultra-Fab A-frame jacks such as # UF38-944037 have a 25 amp circuit breaker to handle the draw of the motor so the battery will need to be rated at least that high which usually isn't a problem for 12 volt car batteries. The slow blow fuse is actually a 30 amp. A breakaway battery will not be sufficient since the amp hour rating is too low. You really need an actual car battery.
view full answer... - Will Ultra-Fab Electric A-Frame Tongue Jack # UF38-944037 Work on 20-ft Triple-Axle TrailerThe Ultra-Fab Electric A-Frame Tongue Jack # UF38-944037 that you referenced is intended for bolt-on or weld-on mounting on A-frame trailers that have a mounting plate with 2- or 2-1/4-inch hole spacing. This powered jack has a 3500-lb lift capacity. You will want to know the weight rating of the trailer so you can be sure this jack will have enough capacity. For example, if your trailer carries heavy equipment, like a bull dozer for example, or a large power boat then this jack may be...
view full answer... - Replacement 2 Inch Round Electric A-Frame Trailer JackWe do have a few electric A-frame jacks with a 2 inch diameter outer tube: Stromberg Carlson # JET-2500 rated for 2,500 pounds. Ultra-Fab # UF38-944017 rated for 3,500 pounds. Ultra-Fab # UF38-944037 rated for 3,500 pounds. This jack also includes a 7-way trailer connector Ultra-Fab # UF38-944016 rated for 4,000 pounds. Each jack offers 18 inches of lift. I've also attached videos of each one for you.
view full answer... - Troubleshooting Ultra Fab Powered Jack that Stopped Working After Winter StorageThe Ultra-Fab Electric A-Frame Jack # UF38-944037 that you have gets power by plugging into a trailer connector 7-way on a vehicle. Typically what you described is corrosion on the connector from driving through the winter. Try cleaning of all of the pins on the 7-ways of both the vehicle and the jack and try again. If still nothing you will want to verify that the 7-way on your vehicle does have power on the 12 volt circuit. This is the 1:00 pin of the 7-way on your vehicle.
view full answer... - Will Ultra Fab Powered Jack Replace Lippert Powered Trailer JackYes, the Ultra Fab jacks part # UF38-944037 and # UF38-944017 would easily replace your Lippert powered A-frame jack. These jacks all use the same mounting bolt pattern.
view full answer... - Manual Crank Option for Ultra Fab Powered A-Frame JackFor the Ultra-Fab powered A-frame jacks there isn't a manual crank handle available since the manual crank is a 14 mm bolt head. This was designed so that you wouldn't have to remember to keep a crank handle with you and could just use a wrench and/or socket. The only option we have is the part # UF48-979005 which can fit a power drill and allow you to quickly operate the manual crank.
view full answer... - Are Fuses Needed on the Wiring for the Bulldog Powered Drive Trailer Jack BD500200The Bulldog Powered Drive a-frame trailer jack # BD500200 is circuit protected internally so additional fuses or breakers are not required. The jack should be ran off of a trailer mounted battery and not off of the 12 volt circuit through the trailer connector. Tow package wiring is not heavy enough for the full amperage draw of the jack and it could result in melted tow package wiring and/or a drained vehicle battery. For a jack that was designed to plug into a 7-Way trailer connector...

I have included a picture showing several external measurements for this jack.

- What Is Length Of Wire Harness On Ultra-Fab Products Camper Jack # UF38-944037 The wiring harness on the Ultra-Fab Products Camper Jack, part # UF38-944037 measures 45-1/2 inches long. The jack has a hook and loop strap to secure the wire harness when it is not being used.
view full answer... - Electric A-Frame Jack that is Shortest in Height Above Mounting BracketThe etrailer jack part # EJ-3520-BBX has a height of 20-1/2 inches from the mounting bracket to the top of the jack. Which from everything I looked up appears to be the shortest overall height from bracket to top of jack. Since you need 22 inches or less in height this would work well for you.
view full answer... - Replacement Jack for 2014 Legend Enclosed Trailer with A-FrameIt sounds like you likely have an A-Frame trailer, so you can use something like the etrailer Round, A-Frame Jack - Sidewind - 15" Lift - 5,000 lbs # TJA-5000S-B which will attach to the 3 mounting points on the trailer tongue and provide you with a jack with 15" of lift. This jack doesn't come with a foot so you'll also need the Footplate for 2,000-lb and 5,000-lb Round, A-Frame Jacks # JF-99, which is designed for that jack. If you're looking for an electric jack then something like...
view full answer... - Powered A-Frame Trailer Jack Recommendation that Has Separate Power and Ground WireIf you cut the 7-way off of the Ultra-Fab Electric A-Frame Jack # UF38-944037 you'd have a red wire for the power circuit and a black wire for the ground that you could run directly to the battery.

As we do not carry this particular breaker 38-101283 anymore you can replace it with a 20-Amp Pollak Circuit Breaker # PK54520

- How Does the 5K Husky Super Brute Electric Trailer Jack Get PowerThe Ultra-Fab Phoenix trailer jack # UF38-944055 does get powered by a trailer-mounted 12 volt battery. It has a power wire that will attach to the positive battery terminal or to the 12 volt circuit at a junction box (if the trailer is equipped with one). The other wire is then attached to the negative side of the battery. Another option is Ultra-Fab jack # UF38-944037 which plugs into a 7-Way trailer connector to get its power from the 12 volt circuit. This jack is rated for 3,500 pounds...
view full answer... - Is a 3,500 lb Powered Jack Strong Enough for a Trailer with 7k Axle CapacityFor your trailer a 3,500 lb powered jack like the part # UF38-944037 would be more than adequate. The lifting strength for a jack is rated for the tongue weight of the trailer. If your trailer weighed 7,000 lbs you would have tongue weight of around 700 lbs so this would work well. This jack powers by plugging into a 7-way trailer connector. If you wanted one that hardwires to a trailer you would want the part # UF38-944017 instead.
view full answer... - Can Electric A-Frame Jack Install In Place of Fulton F2 Trailer JackThe great thing about A-frame trailer jacks is that they all use the same mounting flange bolt pattern so you can remove your Fulton F2 and install an electric jack in it's place like the part # UF38-944037 and you'd be set.
view full answer... - Is Mounting Hardware Included with Ultra-Fab Electric A-Frame Jack # UF38-944037You will source your own hardware for installation of the Ultra-Fab Electric A-Frame Jack # UF38-944037 on your a-frame trailer. Grade 5 stainless steel hardware is recommended and the mounting flange has two hole patterns for convenient fit with 2-inch or 2-1/4-inch hole spacing on your trailer frame.

Absolutely perfect in fact I used my trailer today, I had a little trouble with my first electric jack , You couldn’t ask for a better company they sent me another jack under warranty I returned the old one in the same box, took it to UPS done. It’s very satisfying to deal with an American company that really stands behind their product. Thank You
