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.

Average Customer Rating:  4.7 out of 5 stars   (105 Customer Reviews)

Switch-operated jack has 18" of screw travel and a 4-1/2" drop leg. Retracted height is 9-1/2" and extended height is 27-1/2". 7-Way plug makes setup easy. Extends 6" in 29 seconds with 1,000 lbs of tongue weight.


This jack was the perfect solution for my application. I have a new enclosed trailer that came with a manual crank and only a tiny battery to run the lights. I did not want the expense of having to buy and cable up a larger battery to just support the tongue jack. Took me 5 minutes to install this new jack using the three bolts that were already on my OEM jack. Now I just back up my truck, plug in the 7-way, and I'm able to move the tongue up and down as needed. Great!


This electric jack has made my life easier. I use my trailer for a mobile business and it has a 800lb tongue weight. This jack has seen a good amount of use in the last year and I've had no issues. This is a solid product and I'd recommend it.


I love my new electric trailer jack ! It has a 7 pin RV plug which makes it so convenient to power. There are lights on both sides to shine onto the hitch after dark. There is a bubble level on top to know when the camper is at least level enough to start setting up. It all works great !


Product is great. Easy to install. Performs as expected. One of the best accessories I purchased for my race trailer


Poor quality jack quit working. Again. This is the third Jack I’ve had to buy. It’s too expensive to send it back so there really is no point. I am never buying from you again.


Replacement of the manual jack with the "A" Frame electric jack is among the best purchases I have ever made. Ease of installation and operation make hook up and removable of my trailer almost effortless.


Good jack but there are better on this site for the money. The light is useless. On the back side of the jack so does not help with connecting at night. The manual operation requires removing the mini bubble level with a small Phillips bit to use. Other jacks have a simple plug to remove by hand.

With all that said. It does perform the main purpose it was intended to do just fine. I’ve since purchased the etrailer brand same rating for another trailer and think it’s a much better jack.


Failed after 1 month. Sometimes it works, sometimes not. Found that when cranked manually - even a fraction of a turn- it would work off the switch, but only once. That, with the fact that it has to have the a 3 screw cover removed to operate it manually, and therefore every time it failed, makes this unit entirely unreliable.


Easy replacement of the old manual jack. Works great with the pickup outlet.
Better than expected delivery too.


Very simple process ~ easy website to navigate ~ great products!

Frank J.


The trailer jack has been working out great! No problems at all and it’s very convenient!


The problem with this one is the level cap where the emergency crank is has three small screws you need to remove. My other two have a cap that you can remove by hand real fast.If you buy this one keep a small Philips screw driver with the hand crank. Also ALL STICKERS are peeling off do to the coating used on metal. The jack is well make metal parts seem well coated.


Easy to install worked great first time will update if there any changes but happy so far

Peter F.


works good, but i do not like the idea of having to unscrew top to use manual crank , if i am right it was suppose to be a slide to side action




Customer service here is extremely helpful and do their best to get you your items ASAP. Thanks!


Use it on my enclosed car trailer to load and unload cars with low clearance, Jack works 100% satisfied, I use separate battery that I keep charged in trailer

Fred M.


Great wish I had purchased years before


Installed as said! Works great!


This jack works great so far! (Day 1) Except for one minor detail, everything works as described. I have a 2014 Ford F-150 with a factory hitch & 7pin plug. My fuse box did not have the 30A fuse & relay needed to power the jack. Found the exact fuse & relay needed in my glove box. Apparently Ford doesn't install them when installing the hitch & 7pin plug. Not all trailers need this power function. Mostly the fuse & relay are used to charge the battery on a travel trailer via the 7pin plug. I'm pulling a cargo trailer with no battery to charge. Once I installed the relay in slot #9 & the 30A fuse in slot #21 in the fuse box under the hood, the jack worked as described.

I do wish the cable was a rubber jacketed cable instead of a split corrugated tubing. I might change that one day. Also wish the manual crank handle was slightly shorter. I have a V-nose trailer, and the manual crank handle hits the V-nose, not allowing for a complete 360 turn. The level on top is nice, but needs to twist off like some models I've seen. This model requires you to have a Phillips screwdriver to remove the level to get to the manual crank, and then try to keep up with the tiny screws. These are just some things I would change to make this product better.

Overall, I'm satisfied. Time will tell how long my satisfaction lasts.


This has been a great investment for my camper. I did remove the connector, and wired it into my camper's 12v system to make it easier for me, but I'm very happy with this jack. It works great and saves time and (muscle) energy!


Love this jack. However there was an issue connecting to my 2017 F250 SuperDuty. There is no constant 12v power to the plug to operate the Jack. I did the whole internet search and reading and dont listen to all the advice about fuses and relays. There are no fuses and or relays that are necessary. Just pull apart the 7way connector to the jack and remove the wire from 1oclock and replace to the 11oclock position and it will work fine. Before you start to look for fuses and relays just know that there is no relay connections for slot 37.


Shipping was fast and jack works when I plugged it into my pickup. Haven’t mounted it yet but looks like it should fit



It worked when I installed it in late fall when I hooked up to it the spring it wouldn’t work I installed a new switch and still didn’t work.




The person I spoke to regarding an issue with the ordered jack no longer being available, was very helpful in finding another product that would work on my RV. The jack bolted to the RV easily and performs well.


I recently went to a trailer dealer to ask about the electric jack. They don’t carry or install these items per the associate. I quickly remembered my past experience with and looked up the item. They had several options available and quickly shipped it to me ahead of schedule. It fit and works perfectly!


Great jack. Hooked up to my enclosed snowmobile trailer, with 2 sleds inside. Lifted the tongue with no problem. I thought it would be slow but it raised right up. Just think i will never have to crank up the trailer again


This jack is awesome! I have service connected disabilities that affect my arms and this is a lifesaver. It's as easy to install as a regular crank jack, very heavy, and I love the 7-pin plug for power. I installed it on our 3 horse v-nose trailer. I can lift the trailer and pick up the rear end of my 1/2 ton truck with ease.

  • Mounting Hole Spacing for Buyers Products 12 Volt Electric Jack # 3370093500
    A-frame trailer jacks including # 3370093500 use an industry standard mounting hole pattern (with very few exceptions). They are approximately 3 inches on center. Some jacks have slotted mounting holes which is why the measurements are approximate (it could be a little more or a little less than 3 inches on center).

  • No Power on Buyers Products 3370093500 Trailer Jack When Plugged into 7-way on 2002 Ford F250
    I'm sorry to hear that you're having difficulty with your # 3370093500 trailer jack. If you're not getting 12V on the pin in the 1:00 position in the 7-way trailer connector, I'd suspect a blown or missing fuse. The 20A fuse that protects this circuit is in location 115 in the fuse panel located behind the panel just under the steering column. The panel is held in place by 4 fasteners, turn them counter clockwise that he panel can be removed. If the fuse was blown, you'll want to figure...

    You can definitely use the 7-Way on your tow vehicle to power an electric A-Frame jack.

  • Can a Breakaway Battery be Used to Power an Electric A-Frame Trailer Jack
    If your breakaway system is powered by its own battery then it is likely a 5 amp hour battery which is not high enough to power an electric trailer jack, such as # BD500199, since they can draw about 30 amps under load. The other issue is that a breakaway system needs its own dedicated battery and should not be shared by other 12 volt accessories. If your trailer has a 7-Way trailer connector with functioning 12 volt circuit you could use electric jack # 3370093500 which plugs into a 7-Way...

  • Which Wire of Buyers Products Electric Jack Runs to Power Wire and Which to Ground
    Since the power and ground wires of the Buyers Products Electric Jack part # 3370093500 come already wired to a 7-way they are not different colors to identify them easily as normally you wouldn't need to do any wiring to use the jack. With that said the wire that ran to the pin in the 11:00 position is the power wire and the one in the 5:00 position is the ground circuit.

If the jack isn't powered at all when plugged into the 7-Way on your Ram, then it's likely the 12V circuit on the connector is not active.

  • Recommended Electric Trailer Jack Upgrade for a 2022 Gulf Stream Ameri-Lite 189
    The 2022 Gulf Stream Ameri-Lite 189 will accept pretty much any standard electric a-frame trailer jack. I recommend the Electric Trailer Jack part # 3370093500 as it will simply plug into the vehicle trailer connector and pull power from the battery. Therefore, you don't have to do any additional wiring so un-bolt the old jack and install the new with same hardware.

    Because the Buyers Products Electric Trailer Jack # 3370093500 receives its' power from the vehicle's 7 way, the most likely culprit is the 12v power circuit on your 2013 Chevy Silverado. You'll want to test to make sure you're getting ~12v on the 7 way using a multimeter like the # PT89ZR at the 1 o'clock pin on the truck's trailer plug. I've linked a helpful article we did on 7 way wiring, which includes some diagrams that you might find helpful. If you can let me know what the voltage...

  • What Size Jack Hole Does the Electric Jack w/ Footplate Fit
    The outer tube diameter of the Electric Jack w/ Footplate part # 3370093500 is 2-1/4" as with practically every electric jack so if you only have a 2" you will need enlarge the jack hole in order to upgrade to electric. The best way to do this would be with a hole saw but I will be the first to admit this will be difficult if you can't find a way to secure the pilot bit. If you can wedge some wood underneath that would be easiest.

  • Will the Electric Trailer Jack - Drop Leg Work On a 3,300 Lb Trailer
    The Electric Trailer Jack - Drop Leg part # 3370093500 has a 3,500 lb weight capacity which means it would be capable of lifting a trailer with tongue weight up to 3,500 lbs. The gross weight of the trailer is not the main factor, it is the tongue weight therefore the jack would be more than enough for a trailer weighing 3,300 lbs or more.

  • What Electric Tongue Jack Can I Use On A 2020 Palomino Puma Travel Trailer
    Unfortunately Palomino does not list that spec for their trailers. Generally it will be a 2-1/4" hole but this is not exactly universal. Most of the jacks we carry will fit a 2-1/4" hole like the # EJ-3527-BBX. We have a few jacks like the # 3370093500 which require a 2-1/2" hole. For a camper like your 2020 Palomino Puma with a hitch weight around 620 lbs, a 3,500 lb electric jack will be plenty strong.

    If your electric trailer jack has a 7-Way built-into it for power, like the Buyers Products # 3370093500, then it is completely acceptable for you to cut off the 7-Way and run the power to the positive terminal on your 12V battery. Instead of running your ground to the negative terminal on your battery though I highly recommend grounding it to the frame on your trailer. This will be a much better ground option that running it to the battery. You do want to check and make sure that your...

  • Best Way To Gain Tailgate Clearance With Electric Trailer Jack
    There are other ways to help gain tailgate clearance, but disassembling the electric jack # 3370093500 is not the solution.

This will help you get your tailgate down on your 2016 Ram 1500 so you don't have to worry about denting it.

Reason being that sometimes the trailer jack needs more power than the 12V wire from your tow vehicle can deliver.

  • A-Frame Jack for Camper With Low Height
    The dimensions that are important for an A-frame jack are the retracted height and extended height, which tells you what the travel is. It's pretty simple, but the different terms can be confusing. Travel is just the extended height minus the retracted height, and these heights are measured from the bottom of the mounting point to the bottom of the foot. For example, for your low 17 inch measurement from the top of the A-frame to the ground I recommend the Ultra-Fab Electric A-Frame Jack...
