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.

This is a quality made jack, super easy install, lifts my trailer with ease, I like the fact that it has a backup handle Incase of dead battery. I used a different fuse holder, I'm not a fan of glass tube fuse, the contact area is minimal compared to blade style, and I keep spares of that style being that is what my truck and trailer both use.



Jack is still working perfectly, no issues,no complaints!


The Stromberg Jack was delivered on time with all the parts needed and has worked great. I appreciate that etrailer does a one year review unlike others that ask for a review the day it arrives. When I need to order Rv parts I always try to use etrailer


Ordered my electric tongue jack on Monday was told would receive on Friday which I thought was pretty quick received two days later two days earlier than I thought. Was excited went out removed manual jack put new jack on and was done less than twenty minutes easy hookup and works like a dream. Thanks e-trailer for the fast and courteous service. Will do business again with you no more manual connecting and disconnecting

Love it! So does my back.thanks


One year in the jack still works well. The level bubble promptly failed soon after installation, with the liquid inside disappearing even though I have a leatherette cover protecting it from the elements. That being said, it's a bit gimmicky anyway and not really needed.

Cons I would list after a year's service are: 1) jack is SLOWWWWWWW...I ended up getting an Ox Block to minimize the up/down travel. 2) LED night light is so weak its pretty much useless. The switch is redundant with the up/down one and you'll fumble with both.

All in all minor quibbles and I still rate four stars; it sure beats hand cranking!


works great - easy install - great customer service from etrailer and follow-up after sell - and aways the best price for replacement parts





Part came in good styrofoam padding, screws, washers, extra fuses & connector. Nothing missing. Video on line and on email was clear and easy to understand. I am really happy I bought this product.

Ít still working great, I loved it. Thanks


Thanks for the fast service and fast shipping on my order. My order came quick so now I actually have time to replace it, before next Wednesday. We are going camping next week


The trailer jack works perfectly and was easy to install


Jack works great. it was put on a racing trailer that is very heavy on the tongue.


I bought this jack to replace a Lippert unit that seized in 1 1/2 years of light use. This was my first purchase from Etrailer and I am really impressed with the service! Order was shipped immediately and free along with a tracking tool that showed exactly where the jack was while in transit to me. The jack arrived in great condition and had everything I needed for installation. The install was a three bolt operation and a one wire connection to my existing relay. Saved a bunch by doing it myself and it was easy. I am really going to like the bubble level on this jack! I used to run back and forth from inside to out while balancing. The bubble level shows you right at the jack. I have a 21 foot travel trailer and this jack works great. Can't speak for durability yet as I just installed. Look forward to ordering anything else needed for my trailer from these guys. All the good reviews they have tell you the story! Thanks, Jeff


Item arrived a day early. Installation was easy. Jack works smoothly. 3500# rating is 500# better than the factory installed jack.


I purchased this product and the cover at the same time due to the features and a small part the level on the top. This was after speaking with Troy in depth about it. etrailer, Troy and the videos are great and the product was delivered when Troy said it would and in good condition. I installed it in a relatively short amount of time with my wife cheering me on with a glass of wine.

The one aspect to consider is the mounting plate of the product is round and my original manual tongue jack had a triangular plate. When I tried putting the product on, the battery box was in the way of the round mounting plate. I had to move the battery box back a couple of inches and reattach it for the mounting plate to fit correctly. This only delay the install a short amount of time. Otherwise no issues.

I went camping for 1 1/2 weeks at 2 different campgrounds and I utilize a weight distribution/sway control system to pull the trailer. The jack lifted the trailer and the rear of the truck up high enough to attach the system to the trailer without issue.

So far the product is working fine with no operational issues, however the bubble on the level has grown to where it is not giving me a better idea of how the trailer is leveled. So I am not sure if there is a small leak to cause this or was it from the heat.

If you would like the bubble level and replacement manual override cover is available as a replacement part # 2500-3755E.


The product was great. It is just what you said it was. If you notice the mouting plate, the extensions are to raise the jack up because this trailer sets really low. The origial hand crack jack was bent when I purchased the trailer. Problem solved. This power jack compared to hand jack is the same distance from mouting plate to bottom of foot, both colapsed all the way. My wife loves it, no more hand cranking. Ran power wire inside to battery. Crimp terminal on wire. Hook to battery. Done. Installation, 20 minutes. I purchased cover (bag) to go over power head too. On another note, All 3 tire covers fit like a glove. Now to get a price on 3 new tires. Then we can enjoy it. Thanks etrailer. other products I puchased were great also.


I am very happy with my power jack. Works great, looks good & was easy to install.

The electric jack is still working great! We have had no problems with it at all since we bought it.


Great Jack, lifts trailer with ease, I'm using it on a toy hauler that has 1000lb tongue weight, better to have enough power than overload and burn up motors.



Still works as it did the day I installed it, perfect! Im sure it will work for years to come!


Life changing. Love it!



Love it! Game changer. Everyone should have an electric jack on their horse trailer.

@Lyn We're glad to hear you like your electric jack, thank you for checking in!


Super fast delivery! I paid the $2 or $3 extra to get it in 3 days and I got it in two days! AWESOME! Thanks so much for the fast service as I have a big trip planned next week. The jack fit perfectly. It was super easy to install in place of an existing faulty jack. SOOO MUCH easier to hook up the big travel trailer. I am looking forward to a fun filled trip without having to worry about this any more.

It does it’s job. I use it with a weight distribution system so it’s actually lifting my suv and camper works well. But I believe with any electric toy he jack u should use a cover regardless of what the manufacturer says.

I bought this jack to replace the one I bought locally from a camper store. After the second one of theirs stopped working just past the warranty period. I moved on to this one. I truly think adding a cover over the tounge jack made all the difference in the world. The jack works great, never any problems. I even had to use the manual crank once too. that worked great as well. I would suggest this product.


Very easy install. Lowered my trailer onto two 2 ton jacks and dropped this right in. Torqued to 20 lbs, wired and done. Pretty quiet and not as slow as others I’ve researched.


The trailer jack is a well built item. It runs smoothly and is very quiet. The jack came with a fuse assembly that I was not aware was included. Pricing was very good compared with local stores and other internet sites.

The only complaint is cosmetic. The motor unit on the part received does not line up directly above the center bolt. The motor assembly is off about 10 degrees from dead-center above the forward, center bolt hole.



Still going strong.


So far so good. Very smooth operation and reasonable speed. Install was easy, but directions were just a bit unclear. Images in the manual could be more legible. The in-line fuse holder came in an unbroken loop and needed to be cut and stripped in order to install, and this step (though obvious) was not in the instructions. Overall I would order this product again and recommend to others.



Jack died while boondocking in Colorado. Our tongue weight was about 1100lb and we travel with a loaded f350 srw gas. Jack used to set Wdh bars and had to lift both trailer tongue and truck bed. Not sure if a 3500 lb jack was enough for that purpose. Replaced with a heavier jack same mfg.


The tongue jack was just as advertised and came in quickly. I am 69 years old and had no trouble with the installation. It bolted to the existing bolt holes and works great. I should have gotten it long ago.


Item arrived in a week. Very well constructed, new mounting bolts were included. Fast and easy installation. I'm very particular about routing wires and I was still done in less than a half hour. I'll be using it this weekend .


Jack worked as expected all last year and then RV sat for awhile and wasn't working about 2 weeks ago. I called company and rep said it could be a ground problem and to unbolt jack from trailer and sand down to bare metal for a good connection as that is how the jack is grounded. It worked.
