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.

It is a good replacement for what I had and fits nicely under the jack-it bicycle rack stand.

Arrived promptly and complete. Easily installed. Works great!
by: Adam 04/14/2023
One year in and this has been a great jack. Picks up a lot of weight with no effort. I always keep a bucket or coffee tub over them to keep water out, makes a big difference on the life of them!

The product was as advertised but the customer service at etrailer is exceptional. The product was delivered in the quick timeframe they said it would be and the order was complete. Thanks etrailer. I’ll be back.

Hurricane Sandy is keeping us from installing the jack. But if the jack works as good as the customer service we'll be fine. Quick delivery!

Fit perfect on my Carry-On Trailer.
by: Henry 05/03/2024
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.
by: Ernest09/13/2022
Direct, bolt-on, replacement for my previous 2000 lb tongue jack. I use it on a 7500 lb (gross wt) flatbed trailer with removeable 4" sides that hauls everything from firewood to cars. I no longer worry about overloading the jack.
Nice finish too. It's the nicest looking thing on the trailer!

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.
by: Miles Gregory11/26/2023
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.
by: Greg12/05/2023
Great product. Very smooth while turning the jack handle
by: MUNSTER07/28/2013
GREAT JACK TO WORK WITH, I RETROFIT IT FOR MY RESTORED VINTAGE TRAILER. WHAT A IMPROVMENT OVER THE ORIGINAL HADCO STRIPPED OUT JACK, WELL AFTER ALL THE ORIGINAL WORKED FOR OVER 40 YEARS IT SERVED ITS TIME.
by: Robert C11/07/2013
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.
by: Mike G.09/20/2013
I love this design. The installation went great until I tried to attach the foot to the end of the stem. The stem would not fit into the foot. So I am waiting for a new foot to match this jack. :( The bolt holes lined up perfectly with the threaded holes in the trailer tongue. The only other features I would like to see for this product would be a waterproof cover to place over the top of it to keep water out of it and a grease fitting to lubricate the gears.

See what our Experts say about this Bulldog Trailer Jack
- Will Bulldog Trailer Jack # BD155157 Replace A-Frame Jack on Horse TrailerYou gave enough info for me to know that the Bulldog jack part # BD155157 that you referenced would fit as a replacement and work well. Over time the jacks will start to get hard to operate like what you older jack is doing so it would be time to replace it.
view full answer... - Can the Handle on Bulldog A-Frame Trailer Jack, # BD155157 Be Rotated to Face the Other DirectionIn order to make the handle face the other way when mounted on the trailer, all you would have to do is mount the Bulldog Jack, # BD155157, so that the handle is facing the way you want. The bolt hole spacing on the jack is evenly spaced, 3 inch a part on center. If you need a compatible wheel, you can use # BD500245.
view full answer... - How Far The External Gearbox Protrudes From The Upright Round Pipe On The Bulldog Jack # BD155157I went out in the warehouse and measured the Bulldog Round, A-Frame Jack w/ External Gearbox # BD155157. The dimensions on the external square gearbox that is at the top of the jack measures 2-13/16 inches wide x 2-13/16 inches long x 2-1/4 inches tall. The two bolts with the nuts on the end in the gearbox have a length of 3-1/4 inches. So the dimension from the round pipe to the end of the bolt with the nut on it is 5/8 inches. This would be the amount of the gearbox that will protrude...
view full answer... - Trailer Jack Recommendation for 2016 Jayco 174bh Baja EditionI pulled up pictures of your 2016 Jayco 174bh Baja Edition and it appears to have a standard A-frame style jack installed with a sidewind handle. The Bulldog jack part # BD155157 would be a great option as it mounts to a-frame trailers like yours and has a 2,000 lb capacity.
view full answer... - Corrosion Resistant A-frame Jack Needed for a Boat Trailer Used in a Salt Water Marine EnvironmentThe most corrosion resistant jack for your application is the Bulldog Round A-Frame Jack, # BD1550101344, that you mentioned. This jack has a clear zinc finish and will last much longer in the salt water environment you described. 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...

This jack will measures 13 inches from the bracket to the top of the jack. It offers 13 inches of lift and is rated for 2,000 pounds. Another option is the Pro Series Round, A-Frame Jack w/ External Gearbox # PSRV20000103. This jack is also 13 inches from the bracket to the top of the jack. It's also rated for 2,000 pounds and has 14 inches of lift. A third option is to replace your ball mount...
view full answer... - Distance From Mounting Flange of Bulldog Jack BD155157 to Bottom of Outer TubeThe distance from the bottom of the mounting flange of the Bulldog Jack part # BD155157 to the bottom of the outer tube of the jack measures 6-1/4 inches.

- Recommended A-Frame Trailer Jack For Trailer With 3-1/2 Jack Mounting Hole SpacingI have another option for you, but the standard mounting hole spacing is 3" as you mentioned, and we do not offer a jack with mounting hole spacing of 3.5". Instead you will need to weld the jack to the tongue of your trailer. I recommend the Bulldog Round, A-Frame Jack - Topwind - 15" Lift - 2,000 lbs # BD155022 if your current jack is a topwind, or # BD155157 if your jack is sidewind. Both of these options have a 2000lb weight rating which will mean you will have an easier time raising...
view full answer... - Which A-Frame Trailer Jack Sticks Up The Least From The Mounting Flange On Coupler?The shortest A-Frame trailer jack measured from the top of the mounting flange to the top of the jack is the Bulldog Round, A-Frame Jack w/ External Gearbox - Sidewind - 13" Lift - 2,000 lbs # BD155157. The crank on this jack is below the top of the jack, so in this case the highest point is the top of the jack itself. This jack measures 13" from the top of the mounting plate to the top of the jack as shown in the included diagram, and will give you the most clearance to be open your tailgate....

- How Does Buldog Trailer Jack # BD155157 get LubricatedThe Bulldog Jack part # BD155157 does not have any grease fittings so to lubricate it Bulldog would recommend a lubricant spray like # L11474 basically shot up the inner leg to get the moving parts.
view full answer... - Can the Handle of the Bulldog Winch # BD155157 be Installed in the Opposite PositionIn order to make the handle face the other way when mounted on the trailer, all you would have to do is mount the Bulldog Jack, # BD155157, so that the handle is facing the way you want. The bolt hole spacing on the jack is evenly spaced, 3 inch a part on center. The handle itself cannot be mounted in a different position on the jack.
view full answer... - Flange Dimensions of Bulldog Round A-Frame Jack # BD155157The 3 bolt holes of the Bulldog # BD155157 Jack are 3-1/4 inches apart on center. If you refer to the photo I edited for you, can can see all of the mounting plate dimensions.

- How to Install the Bulldog Replacement Sidewind Handle and Gear KitInstalling the gears is fairly easy, You will need to remove the cap at the top of the jack. The handle and gear are held in place with a roll pin that will need to be removed. You can then remove the handle, square block and gear. You can then remove the bottom gear by lifting it out. If the bottom roll pin is damaged remove it also and the washer can be replaced after removing the lower pin. I added a photo showing the inside of a Bulldog jack with an external gear box, like part # BD155157,...
