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:  4.8 out of 5 stars   (471 Customer Reviews)

Ideal for multiple agricultural and commercial applications, this corrosion-resistant, A-frame jack features a 7" retracted height and measures 14-1/2" from the mounting bracket to the top, excluding the handle. Base sold separately.


Well made and sturdy. Cranked the jack to fully extend the tube and noticed that during the entire mid-range of extension the cranking was very stiff. It was much easier near the limits (fully retracted and fully extended). Hope this doesn't become a problem under load.


Using the "Bulldog Round, A-Frame Jack - Sidewind - 13" Lift - 3,000 lbs" in combination wth the
"Drop Leg for etrailer & Ram Jacks - 13-1/4" Tall - 5-1/4" Diameter Footplate" allows me to run this jack, without the drop leg attached, flush with my trailer frame for better off road clearance, and with the drop leg while taking the trailer off the vehicle, minimizes turning of the jack.







This jack works much better than the poor quality original one from china. It gives you more ground clearance and is strong enough to pick up the trailer.


Thank you for your inquiry. I just yesterday found time to install the Bulldog jack. The package shipped and was delivered earlier than promised, which was a pleasant surprise. I was impressed with the quality of the jack just taking it out of the box. I am more impressed with it on my trailer (Boatmaster with 17.5 Key West Stealth). It operates smoothly and with minimal effort. I chose to store the boat trailer on blocks rather that use a jack wheel as the wheel hangs too low when towing and installing and removing it is just another task I prefer to avoid. This jack replaces one ten years old used primarily in a salt water environment. It is a very good product. I did attach a picture of the jack.


Product shipped in an extremely timely manor and arrived undamaged due to the quality of packaging. This Jack fit the front of my travel trailer (not commercial) just fine and only took minutes to install. My local trailer parts store was selling tongue jacks of half the capacity for nearly double the price. This was an awesome find and I'm glad i chose etrailer for my purchase. I did not rate 5 of 5 only because I have not had a chance to operate the jack.


Great product wish the had the same exact model except a liter duty for a little cheaper. 3,000 pound lift weight is a little over kill for my 6.5 by 12 foot utility trailer. Like how it fits nice and snug under the frame.


The one it is replacing was awesome and was used for a long time. Haven't taken my sailboat out of the driveway since 2021. 2022 was the first year since 2012 I haven't gone out of state to work and live on my sailboat. So I haven't even put my new A frame jack on yet. still sitting in the box.


This trailer tongue jack is high quality. The perfect replacement for the original jack. Fits exactly. Solid heavy duty packaging ensured this jack would arrive without any issues. Thank you for the quick shipping! Ordered it Sunday night and it was shipped out monday morning. Thanks again!



One year later and still working like new. Excellent quality!


The tongue jack fit perfectly with bolt on instalation in a very short period of time. The tongue weight and ease of lifting is very convenient and the operation of the jack is simple and matches the trailer application.
Nice doing business with your organization!!!



I have used the product repeatedly on my camper. The jack functions great, its a rugged product and durable. I would buy again if the need arises.


So far, so good! It replaced the factory jack on our RPod 172 that broke and was very easy to install. The Bulldog folds up a little smaller for better ground clearance and has a smoother, easier lifting action. Great purchase!

Goin C.


Still going strong. The Bulldog is working out as well as you could hope. No complaints at all.


Delivery was prompt and the product as advertised.




Perfect replacement and it bolted up in two minutes. I can raise and lower my 26' travel Trailer with one hand. Very pleased with the purchase!! The footplate (#PS1400700340) mounting pin hole did not match up though. I will have to drill a new hole for the pin if I want to use it. Not a big deal and am still happy with the service I received and the purchase. Kimberly D. was a great help in finding a replacement for the one I originally ordered that was unavailable. Etrailer has won my future business as well.


The jack is very well made. I changed over from the original top crank jack on our 2005 Casita travel trailer to the Bulldog Side Crank A-Frame Jack which has a smoother mechanism and will be much easier to use. No drilling necessary as it aligns with the existing holes. I gave it a four because they did not include mounting bolts.

A friend installed one of these on his 2013 Casita trailer and feels it is a big improvement over the jack that came with the trailer.


After trying for several weeks to find a replacement jack for my travel trailer I was able to work with your customer service department and get a jack for it. All I was able to find earlier wouldn't fit in the hole in my tongue. I am very pleased with the product.


Part fit perfectly on 20 year old Haulmark trailer. Customer service rep. was very helpful in making sure I got the right part.

John H.


Great works perfectly. Fits in exactly the same spot.


The trailer lift is still going strong after a year. I keep the the trailer outdoors and the is a minor discoloration at the top but no other visual issues. The turn mechanism is still as smooth as when installed. Very happy with the item.


Much better than my original: Since this is geared, it is easier to crank when there is a large load on the trailer. It also seems more robust and durable than my OEM jack.


Amazing product at a reasonable price. Shipping was fast I installed my alert and saved 2/3 of what a trailer repair would have been.
Finding my exact fit and features was easy.

Thank Zhou E-Trailer


The A frame jack and caster are on the trailer with minor drilling to align with existing trailer holes..This is a rugged high quality jack and caster...I ordered the jack Sunday nite late PM and it arrived on thursday here in Boston, how much better service can you get ? Quality product, fastest shipping and excellent communications from


overall good product, no problems with installation, worked well out of the box, castor wheel fit easily, One thing that would be nice, is a strap to hold the handle in place when the shaft is retracted, this would hold it still and prevent it from swinging around when driving down the road, will probably make one out of velcro. Overall, no major grumbles.


Works great! A definite upgrade from the original Jack that came equipped with my 16’ cargo trailer.


Built heavier than I expected for the money spent. Cranks up and down with ease. Made my decision from reading reviews on this site. Cheaper buying here at than AMZN, even though I paid shipping here. Seeing a picture of it on the same style trailer that I was intending to mount it on, assured me that I was making the right choice. This was my 1st purchase through, but not my last.


Replacement for a damaged rack and gear style A frame jack. Works as advertised at a fair price. Because of limited ground clearance i have to remove the wheel when I am towing the boat. I realized that is part of the design of this style jack.

  • Replacement for a Fulton Marine Trailer Jack Model # 0926012
    A-Frame jacks utilize the same triangular bolt pattern so that any A-Frame jack can be fitted to any A-Frame coupler. The Bulldog part # BD1550101344 is an A-frame jack with a 3,000 lb capacity that would work well. Bulldog and Fulton are actually both made by the same company as well.

  • Is a Support Plate Needed When Installing Bulldog A-Frame Trailer Jack # BD1550101344
    It would be a good idea to add a support plate, like # BDSPB50, when installing A-frame jack # BD1550101344. The plate can be welded or bolted on. This plate fits on the underside of the trailer. The jack will then bolt into place. If you need a foot use # PS1400700340 or for a wheel use # PS1400750340.

  • A-Frame Jack Recommendation for Travel Trailer with Propane Tank Right Behind Jack
    As far as the Ultimate Trailer Jack # 322-RDJ-2K goes the design, and more specifically the placement of the pin, is placed close to the mounting point of the jack because that is where the jack is most stable. As far as I know they are not yet making one that would work out well for your travel trailer. Your best option is a different jack that doesn't stick down so far below the trailer frame. Bulldog 3K jack # BD1550101344 is one option. Without a footplate on it measures 7 inches from...

  • Recommended A-Frame Trailer Jack for 7000 lb Trailer
    You will need to choose a jack whose capacity exceeds the fully loaded and ready to tow tongue weight of your trailer. Typically trailer tongue weight is 10-15 percent of the weight of the trailer. This means that when loaded to maximum, your tongue weight would vary between 700 and 1050 lbs. I recommend the Bulldog A-Frame Jack, part # BD1550101344. A foot is available, part # PS1400700340. A caster is also offered, part # BD500245. Keep in mind that once a caster is added the capacity...

  • Can Handle on Bulldog A-Frame 3,000 Pound Trailer Jack be Moved to Opposite Side
    It is not recommended to change the configuration of the handle relative to the rest of Bulldog trailer jack # BD1550101344. But what you can do is turn the whole jack and bolt it back down again to move the handle.

  • Can the Caster Wheel Be Removed on the Bulldog Rack and Gear Jack
    The wheel on the Bulldog Heavy Duty Rack and Gear Jack # BD165411 cannot be removed, but when fully retracted the wheel will only extend 7-1/2" from the A-frame mounting bracket, so the clearance is pretty good. We do not carry a rack and gear jack that the caster wheel can be removed on, but there are some other options that can have the wheel/caster removed from. If you wanted a jack that did have a removable wheel then I recommend using the Bulldog Round, A-Frame Jack - Sidewind -...

  • Availability of A-frame Trailer Jack with Crank At Rear for Truck Tailgate Clearance
    The mounting bolt holes for the Bulldog # BD1550101344 A-frame trailer jack are each 3 inches on center apart. This means that the jack can be installed so that the crank is to the front or to either side, which might allow your tailgate to clear. If you can get by with a 1000 lb capacity jack, the Dutton-Lainson # DL22530 can be turned so the crank is to the rear of the jack. I've linked you to a product demonstration video as well as to a photo showing the Dutton-Lainson jack installed...

  • Replacement for a Fulton Marine Trailer Jack Model 0926012
    The most comparable replacement for your Fulton model 0926012 3K capacity A-frame trailer jack would be the Bulldog # BD1550101344 which offers the same capacity and amount of lift as your current jack. The jack features a zinc finish that offers good corrosion resistance. You could certainly go with a higher 5000 lb capacity jack like the Bulldog 1700100117, but we don't offer that jack. If you're wanting something with a bit of a higher capacity, I'd recommend something with a tough...

  • Topwind Trailer Jack vs. Sidewind Trailer Jack for A-Frame Trailer
    The difference between top wind and sidewind is really mainly about personal preference and somewhat about clearance. Basically which way to you want to crank the jack? Horizontally or vertically? Based on your picture you'd easily be able to use either style. I prefer sidewind jacks like the part # BD1550101344 which is galvanized to prevent corrosion. Personally I find topwinds a bit more awkward to crank especially under weight.

  • Short Trailer Jack Recommendation for a 7000 lb A-frame Horse Trailer for Tailgate Clearance
    I went out to my warehouse a pulled a few different jacks that I think will work for you. The Bulldog Round, A-Frame Jack, # BD1550101344, measures 14-1/2 inches from the bracket to the top of the jack, but you will lose an inch of lift with a 13 inch lift. You do, however, gain an increase in weight capacity at 3,000 lbs with this jack. Our best option may be the Pro Series Round, A-Frame Jack, # PSRV20000103.

  • Recommended Trailer Jack to Use with Bulldog Heavy-Duty Cast Head Coupler # BD44150WH301
    I do have a solution for you, however the Bulldog Square A-Frame Jack referenced in your question will not work well with the Bulldog Heavy-Duty Cast Head Coupler # BD44150WH301. This is because this particular coupler features a 2-1/4 inch diameter hole that is designed to accept round tube trailer jacks, not a square design like the Bulldog model you mentioned. For this coupler, I instead recommend looking at the Bulldog Round A-Frame Jack # BD1550101344. This is another great 3,000...

  • Will Bulldog A-Frame Jack # BD1550101344 Fit 2,000-Lb Boat and Trailer and Be Corrosion-Resistant
    The Bulldog Round Sidewind A-Frame Jack, part # BD1550101344, has a lift capacity of 3,000 lbs and will work fine on your 2,000-lb boat and trailer for lift capacity. The lift capacity means this jack is able to lift and support up to 3,000 lbs. An A-frame jack like the Bulldog is mounted on the tongue of the trailer so it is rated to lift the tongue weight of the boat and trailer. If you have a 2,000-lb boat and trailer, the tongue weight range would be 10 to 15 percent or 200 to 300...

    The most corrosion resistant jack for your application is the Bulldog Round A-Frame Jack, # BD1550101344, that you mentioned.

Stepping up to a 3,000 pound jack will make cranking the trailer a bit easier than a 2,000 pound jack and will help the jack to last longer. If your trailer requires a top wind jack, or it would make turning the handle easier on the A frame trailer, you could...

  • Jack Replacement for Broken Inner Leg of Fulton Jack
    I wish that part was available, but our trailer jacks do not have replacement inner legs available. The Bulldog part # BD1550101344 is an A-frame jack with a 3,000 lb capacity that would work well. Bulldog and Fulton are actually both made by the same company as well.

  • Will Mounting Bolt Pattern On a Bulldog A-Frame Jack Match the Bolt Pattern On a Fulton A-Frame Jack
    All A-Frame mounted jacks like the Bulldog Round A-Frame Jack, part # BD1550101344, 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. You will want to make sure and replace your current A-Frame jack with a jack of similar specifications with a lift capacity the same or higher.
