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: Lon D.06/18/2017
Installed it and used it camping this weekend my only question to myself was why did I wait 3 years to buy this ??.......in one word this electric tongue jack is... AWSOME ...easy installation works perfectly stop thinking about it just buy it you will thank yourself every time you use it.

After one year no complaints still working GREAT !!
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: 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: 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: 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: 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!

Products are performing as advertised! fully satisfied.
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.
by: David11/02/2017
Works great. Put it a Jayco and when I traded it in kept it and put on my new Summerland. It does all that I hoped and has made hooking up and unhooking a breeze. It has made my setup quicker and easier. I am glad I purchased it. Also, your price is so much lower than anyone else for the same jack. I love that is power by my tow vechile and I can still use it if my battery on my trailer dies or is discharged.
I would highly recommend it to others to purchase.

- Can a Manual A-Frame Trailer Jack be Raised and Lowered Using a Power DrillLike you said there are some stabilizer jacks and even some winches that will allow you to attach a drill to raise/lower or reel in legs or line much faster. But there are no A-frame jacks, or any regular trailer tongue jacks, that I have seen that have this type of feature. If manually cranking the handle starts to be a chore the best option is to go with an electric jack. The most cost effective one is Ultra-Fab jack # UF38-944037 rated for 3,500 pounds.
view full answer... - Powered A-Frame Trailer Jack Recommendation for a 6,500 lb TrailerTypically a trailer's tongue weight will be between 10 and 15 percent of the total weight of the trailer. Since your total trailer weight is 6,500 lbs your tongue weight would be between 650 and 975 lbs. The Ultra-Fab Electric A-Frame Jack # UF38-944037 has a 3,500 lb capacity so it would work well on your trailer and would have more than enough capacity.
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... - Attaching Ultra-Fab Electric A-Frame Jack Directly To Trailer BatteryTo wire the Ultra-Fab Electric A-Frame Jack, part # UF38-944037 to your trailer, all you have to do is cut the plug off, separate the red from the black wire and connect the red to the positive post on the battery and the black wire to the negative post on the battery. My contact at Ultra-Fab also told me they recommend using an inline 40 amp fuse for the positive cable.
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... - 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...
view full answer... - How Much Does Ultra-Fab Electric A-Frame Jack # UF38-944037 WeighThe Ultra-Fab Electric A-Frame Jack # UF38-944037 that you referenced weighs a total of 21 lbs. I attached a review video for this jack for you to check out as well.
view full answer... - Length of Ultra Fab Powered A-Frame Jack from Mount to Bottom of Foot RetractedWhen fully retracted the Ultra Fab Jack part # UF38-944037 that you referenced has a distance of 9-1/4 inches from the mounting bracket down to the bottom of the foot. Fully extended this measurement would be 27-1/4 inches. The foot of the jack is removable as well. I also attached an install/review video for this jack for you to check out.
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.

However, the head can be installed in which over orientation the bolt holes on your trailer allow. And if you needed you could always drill new holes so the head faces the exact direction you'd like it to. We do have the Ultra-Fab Jack # UF38-944037 that has a few options for different bolt hole spacing. Another solution that may work for you is a longer ball mount like # BH20.

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... - 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... - 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.

Ultra Fab Electric A-Frame Jack # UF38-944037 uses a 7-way RV-style plug to make its two wiring connections, ground and +12V. The other locations in the plug have no contacts. You can test both the vehicle's trailer socket and the jack's plug to determine where the problem is. If you have a circuit tester like # PTW2993 you can apply it to the pins on your vehicle 7-way.

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...

This jack will give you 10" of travel in just 18 seconds, making it the sports car equivalent of electric trailer jacks; it has 22-1/2" of total travel and a 4,000 lb lift capacity, which is more than enough for your Forest River.

- Will the Ultra-Fab Electric A-Frame Jack # UF38-944037 Fit a 3 inch Bolt Pattern Mounting BracketAll A-Frame mounted jacks like the Ultra-Fab Electric A-Frame Jack # UF38-944037, use the same 3-inch mounting hole bolt pattern. In other words, the mounting holes are a universal size and pattern so that any A-Frame jack will fit into any A-Frame jack mount. As long as your trailer has an A-Frame jack mount, this jack will fit.

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
