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.

Great looks. Powerful Jack. I mounted a dedicated battery to it so I would not have to depend on my vehicle’s thin wiring. Questions that I had during the installation were promptly and professionally addressed by etrailer’s technical dept. amazing help and support. Thanks

This jack is amazing. Gets a regular workout and still works great a year later.

No complaint with Electronic Jack. Customer service at e trailer is Exceptional!!!


Easy installation. Works great.


Last summer we bought a new truck to tow a new concession trailer. The differing heights of the two vehicles, along with the pitch of our driveway made it impossible to unhitch our trailer. We purchased this power jack hoping it would help. This jack allowed the tongue of the trailer to raise higher to allow the ball of the hitch to release. The ease of pushing a switch compared to cranking it by hand makes it worth every penny we spent to get this jack. I found the prices at etrailer to be far better than anywhere else I looked for this item. Great customer service sealed the deal.

Still working great, would purchase again.

1 year in and this jack has been a lifesaver! Never again will I spend 20 minutes cranking my enclosed trailer up and down in 90mph Wyoming wind. I'm in the market for a new trailer and I guarantee it'll have this jack installed immediately.


Easy installation - Less than 20 minutes
quiet operation
Love the product in less than 5 minutes


It took months @ months to receive installed jack today seems real slow, not very good quality for the price!!!

You mentioned that you were unhappy with the speed of the jack. I wanted to ask you how fast or slow is the jack moving? Would it be possible to send a short video?

What a great addition to my car trailer. And when others see how you can plug it in for power without having to add an additional battery for power, they love it and so do I. Hasn't let me down yet over the past year with quite a bit of use. I highly recommend this to others looking to add or even replace their manual jack.


Purchased this jack to replace a manual jack we have on our cargo trailer. Swapping it out was easy-peasy! Had an issue getting power to the jack; called for assistance and had enthusiastic help from Nicole. Turns out it was our brand new truck that was the problem...a smart vehicle sometimes needs to be outsmarted in order to allow power to the 7-pin. Overall, very pleased with the purchase and the customer service. Highly recommend!


I ordered the product and I have to say it was very well taken care of by this company and the prices are great I would recommend them if you need one of the product's They fill the order fast and the shipping was great

Thank you

Product is well built and works like it should. Had an issue with a fautly cover not fitting right though. I emailed etrailer and was helped by a person named Hannah. She was great to work with and very helpful getting me another cover shipped out asap. All in all great service and would recommend to anyone.


It a nice jack good stuff th you


Ordered from you several times and never had any type of bad experience. When I need anything for my trailer I always check your site first.


Once I placed the order an email was sent that they received the order. Another email sent that it was processed and shipped. A tracking link was sent and it was accurate. They said it would be delivered by Wednesday September 2nd and it was. I tried the jack and worked exactly like they said it would. Absolute pleasure ordering from etrailer.


Works awesome thank you


This jack works just as expected.. Took maybe 20 min to in stall . Had ordered a different jack and Ricky emailed me with an option of this jack instead as the one I picked was months out of being in stock. Great personable customer service and friendly attitudes at !!


I ordered this jack an am well pleased. It shipped quickly and is a direct bolt in replacement for my camper trailer.


I should have bought this years ago. Installation couldn't be easier. Works beautifully. If needed, customer service is the best. Product price was lowered a week after I purchased it, and a refund was promptly given. I've dealt with this company in the past as well, and they are the best by far.


Does what it supposed to do.

light went out after the first month but other than that it has been a great upgrade from the hand crank.


I keep coming back to etrailer because I've never been disappointed. Thanks


Highly recommended this jack for ease of installing and works great . Delivered super fast. Great great company to buy from.


Works as it should and was an easy inst all.


Product arrived two days earlier than promised. Works as it should. Very happy with my purchase.


I removed the old jack and this one popped right in and even looks good! It appears to be good quality also!


Nice unit. Be sure to chock your wheels on grades for safety.

  • Replacement for Old Hydraulic A-Frame Trailer Tongue Jack
    The Electric Jack w/ Footplate part # EJ-3527-BBX is what I recommend you use to replace your old hydraulic a-frame trailer tongue jack. This will be a great option for the old hydraulic tongue jacks because it simply plugs into a 7-way on vehicle without any additional wiring required. The three hole pattern is an industry standard mounting pattern so you don't have to worry about this either.

  • Recommended Electric A-Frame Trailer Jack for a Forest River Rockwood High Wall
    The Electric A-Frame Trailer Jack with 7-Way Plug part # EJ-3527-BBX would be an excellent option for a Forest River Rockwood High Wall (All Models). The Electric A-Frame Trailer Jack has a 3,500 tongue weight rating so this would far exceed the tongue weight rating of any Forest River Rockwood High Wall.

    The Electric Jack # EJ-3527-BBX, and other jacks that operate from power supplied from the 7-way plug, rely on the ground and 12VDC contacts to deliver operating power requirements. Those contacts are located, respectively, at the 5:00 and 11:00 positions on the plug as you view it. Either you do not have that needed pin powered on your Ford, or you are not making sufficient contact to create the needed circuit. Some powered jacks will not operate if there is insufficient voltage. It...

  • Recommended Trailer Jack For Trailer With 14000lb GVWR
    Since you are limiting your trailer to 10000lbs, and the average tongue weight is 10-15% of the trailer weight, you are looking at 1000-1500lbs tongue weight. With that said it is a good idea to use a jack with a larger capacity as it will be able to work easier leading to a longer life of the jack. I recommend the Electric Jack w/ Footplate and 7-Way Plug # EJ-3527-BBX which has a 3500lb capacity meaning it would be able to work fine even if you loaded the trailer to 14000lbs and had...

  • Can the 7-Way Plug On the Electric Jack w/ Footplate EJ-3527-BBX Be Removed
    The Electric Jack w/ Footplate is offered both with the plug part # EJ-3527-BBX and without the plug part # EJ-3520-BBX. Therefore, if you wanted to go with the model that has the plug and just cut that off you would indeed just run the wire to the battery or you can go with the model that has the blunt cut wire which is more cost effective.

    I do have an option but we do not carry hydraulic a-frame trailer tongue jacks.

If you are switching from a manual to an electric jack then you might want to use part # EJ-3527-BBX since it comes with a plug for the vehicle to power it.
