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 was the third jack for an tandem enclosed cargo trailer that weighs about 7000 pounds loaded. The trailer belongs to a Non-profit living history group of which I am the "Seneschal" which essentially means the guy with the truck big enough to pull the trailer. My responsibilities also include repair and maintenance of all of the gear and the trailer. The original jack was damaged and I had purchased a "speed jack" from another company and installed it last October and did not use the trailer until April of this year. One use and that jack failed. Upon dissection I discovered that the Chinese manufacturer failed to lubricate it and the bearings were rusted and in various stages of disintegration. After a bit of cursing and a bit more internet research I found etrailer. Once I abandoned the idea of a "speed jack" and went with the drop jack, I found that etrailer had what I needed at a competitive price. Calling etrailer lead to a delightful experience rich with excellent customer service with likes of which I have never experienced in my 58 years. I ordered it and was pleasantly surprised when etrailer upgraded my shipping for free. The parts even arrived a day earlier than the upgraded date. I have installed the jack and everything fit as promised. I have attached a picture. I must emphasize that this company has the best customer service that I have ever encountered.

Wow this bulldog jack is awesome I use it daily on my concession trailer, easy to use and very durable thanks etrailer.com

The hardest part about installing it was taking the old, rusted version off the trailer. I usually prefer side crank handles, but couldn't find the appropriate model/weight limit combo so bought this one instead. I was pleasantly surprised at the easy of which this one cranks up and down. I'm a fan of Bulldog products.




by:

Etrailer rocks! They identified what I needed which was a somewhat unique setup and got it to me fast!!! Much appreciated - wish I went to them first.




by:

I can't believe I waited 5 years to replace my broken trailer jack. After using blocks of wood, floor jacks and feats of daring to raise and lower my trailer, I finally took a chance and bought a replacement. If only my foot was longer I could kick myself you know where. This has been the best thing I've done in a while. Don't be afraid to buy from etrailer. They have an excellent product and a very good price. Go ahead and take a chance, you won't be sorry.




by:

My trailer came with a 3000lb capacity jack which was fine for regular use, but adding weight distribution and a lot of forward cargo really showed after a year. This replaced the previous BullDog jack incredibly easy. The hardest part was really getting the new one out of the super secure packaging.

  • A-Frame Trailer Jack for 10,000 lb Box Trailer
    For a high quality topwind jack that would work great on your trailer the Bulldog 5k jack part # BD155032 is what I recommend. It has quite a bit more capacity than the tongue weight of your trailer would have which means it will operate easily and will also last a long time. Like most jacks of this style it does not have a grease fitting but Bulldog has told us that you can spray white lithium grease up the inner jack leg if you want to lube it although it is not required.

  • 5k Rated A-Frame Jack Recommendation
    The closest jack we offer to what you are looking for would be the Bulldog Jack part # BD155032. This is a 5k rated, A-frame jack that has 10-5/16 inches above the mounting bracket for the jack. Check out the review video I attached for more info.

  • Radius of Handle on Bulldog Jack # BD155032
    The handle radius of the Bulldog jack part # BD155032 is 6-5/8 inches including the knob.From the picture you sent in this would likely hit the box on your trailer, but the great thing about the swivel handle of this is that you can angle it up as you come around where the box is and you'll be able to avoid it.

  • Replacement A-frame Jack for 1997 Dutchman Popup Camper with 1-3/4
    I spoke with my contact at Bulldog Trailer Jacks and he said you should not have to file the opening of your camper tongue. A standard sized jack, like # BD155032, which you referenced, should fit easily into the factory opening. The bolt hole pattern on the mounting bracket and the bolt hole pattern on your A-frame trailer tongue are standard, so matching up with the holes should not be a problem. The important thing is to choose a jack whose capacity is greater than the tongue weight...

  • How to Lubricate the Bulldog Top Wind Round A-Frame Jack # BD155032
    According to the installation instructions for the Bulldog Top Wind Round, A-Frame Jack, # BD155032, the only maintenance needed is applying a light machine oil to the stem that the handle attaches to. The installation instructions also recommend thoroughly rinsing the jack with clean water before lubrication.

  • Which A-Frame, Top Wind Trailer Jack is Shortest from Mounting Bracket to Top of Jack
    The A-frame, top wind jack that has the shortest distance is going to be the Bulldog jack you referenced, # BD155032. From the mounting bracket to the top is a little over 10 inches (10.2). Another possible solution is to use a longer ball mount to move the trailer further back so the tail gate can lower without hitting the jack. We have some very long ball mounts, see link, some of which have a distance of 16 inches from the center of the hitch pin hole to the center of the ball hole.

  • Higher Capacity Trailer Jack that Can Fit 2022 Big Tex 14LD
    I looked up your 2022 Big Tex 14LD and it looks like it has an a-frame style trailer jack so for a higher capacity option that would fit we have the Bulldog part # BD155032 which has a 5,000 lb lifting capacity. In this style of jack we do not have anything with a lifting capacity of 12k. Also worth noting is that these jacks only need to have lifting capacity for the tongue weight of the trailer and not the entire weight so a 5,000 lb capacity should easily work for you.

  • Difference in Side Wind Operated A-Frame Jack and Top Wind A-Frame Jack
    The choice between a side wind jack like the Bulldog Round, A-Frame Jack - Sidewind, part # BD1700100317, and a top wind jack like the Bulldog Round, A-Frame Jack - Topwind, part # BD155032, will usually be for clearance issues. A top wind jack will be used when there is something on the trailer that will interfere with the rotation of the side wind handle on the jack and a side wind jack would be used if there is interference for the top wind jack handle.

  • Replacement A-Frame Trailer Jack for a 2006 Forest River Wild Wood Trailer
    It sounds like you have a 5,000 pound capacity A-frame trailer jack. There are many options in this category. If we narrow it down to top wind, bolt-on jacks with a round tube, there are 4 possible options. The 14 and 15 inch lift specification is how much the inner leg travels. For a jack with 15 inches of travel, I recommend the Bulldog Round, A-Frame Jack, # BD155032. If you need a foot plate, you can add # BD018564. I have included a link to a video showing this jack being installed.

  • Bulldog Topwind Jack that Can Crank with Interference Near Mount
    Sounds like your trailer needs a jack with a topwind like the Bulldog part # BD155032. There isn't a way to relocate the handle of the jack you mentioned so a topwind would be your best choice. The topwind jacks can swivel and pivot as needed to which allows them to be even more flexible in how they can function.

  • What is Difference Between Bulldog Trailer Jacks BD155032 and BD1700100301
    The Bulldog A-Frame Trailer Jack # BD155032 is a topwind jack and the part # BD1700100301 is a sidewind jack. Both of them are solid choices and have 5,000 lb capacities but the handles and how they are cranked are opposite of each other. The topwind jack spins horizontally when you raise or lower it and a sidewind cranks vertically. Sometimes clearances or interference with other accessories on the trailer may cause one style to be more advantageous than the other.

  • Side Mounted Trailer Jack Recommendation for a Trailer for Good Ground Clearance
    From the pictures I found of your 2016 r-pod 178 trailer it looks like you have an A-frame jack like the part # BD155032 that you referenced. If ground clearance is a problem with this jack one solution you have would be to replace the jack with one that attaches to the side of the trailer frame and can swivel. The Pro Series Jack part # PS1401060303 uses a pipe mount that would get welded to your trailer frame and would allow the jack to swivel up and out of the way when not in use.

This jack has a retracted height of 5-1/2 inches to give you additional clearance when you are traveling on uneven terrain. This jack also has 2,000 lb capacity, but since you said you only get near that capacity and not over you should be fine.
