I'm sure it would be fine. Now as far as shipping when it got to my address the box was destroyed and it was dented and scratch to hell but its and hopefully it's used able I be installing next week.

I will have our Customer Service team reach out to you. I recommend touching up the affected areas with a rust resistant paint which you will then have on hand for regular maintenance.

This jack continues to work well on my 2 horse GN trailer.


I modified this jack to lift concrete garage floors. It has held up wonderfully we'll!


Customer service couldn’t help me match the one I had. I then called bulldog jack company and they were able to walk me through the one I needed. I completed the order with etrailer and filled in my ship to address which is different than my shop address. I received and email telling me the product had been shipped. When I started tracking the package I realized it was shipped to my home address instead of the address I had requested. I assumed I had made a mistake when I filled out the address with the shipping information. I called and was told they could not ship to a secondary address because I was a dealer. I had to order another one and not use my dealer address to get it shipped to my current location. I have never heard of a company that couldn’t ship to a different address because the receiver was a dealer. Ups couldn’t change the ship to address once shipped because of the way etrailer sent it.


The part is great and the speed of shipping, etc was great. The only reason I’m giving it a star less is because the package arrived in terrible condition. The box was all torn up and you could see the jack in there.

I will have our Customer Service team reach out to you.

Good quality easy to use


Heavy duty, well-built jack. I decided to upgrade my trailer jack for poor performance and after searching the net I came across a video from etrailer describing the features of the Bulldog Square Jack # BD182804. It has every feature you need and some. With the upgrade, I must mention there was welding involved. I first confirmed there was structural support where the jack was to be mounted. I disassembled the jack per the video, located and welded the housing in place, reassembled the jack and lubed with the same grease I use for my trailer axles. It was that easy.


This was a replacement jack for a flat bed trailer. Installed it and it was just like the old one. Very happy with the jack, I recommend it highly.

Our Bulldog jack is still working like the day we bought it. Thanks for the follow up!
Brian - 01/30/2018


I called bulldog about a BD182404 trailer jack that I have on my trailer that has a frozen drop down non- return spring leg and asked them if I could put a spring return drop down leg and all of the internals from a new jack into the old 4"x4" tube.
The tech said I would need a BD 182804 jack and it would all fit, (he was right). The reason for not using the new tube was there was nothing wrong with the old one and by not cutting out the old one and welding in the new one saved hours, thanks to Bulldog for that info.
I also want to thank for their timely shipping and follow through, I appreciate receiving the right part the first time on time, Thanks again.


Item exactly as described and very prompt service and shipping. Great communication from all the fine folks at


We trust in E Trailer and the service provided. Looking forward to doing more business.


As far as I know, this product has worked out well. I have not had any complaints from our employees. It shipped in a very timely manner. I had follow-up emails and a phone call from etrailer letting me know the status of my order throughout the shipping process. I would definitely purchase from this company again.


Nice heavy built jack. Installed it on our 10 ton equipment trailer and it
works perfect. A good jack for reasonable price!
AND was a pleasure to do business with.


Bulldog makes a great product. We bought a seed tender that had another brand of jack on it and it lasted 2 years. We've always had good luck with bulldog as well as etrailer.


Heavy duty weld-on jack great for application of large sawmill trailer at reasonable price. Unit well packaged and arrived without any issues.


The Jack on my trailer quite working after 20+ years. i bought this Jack to replace it. I got fast delivery and it was packed well so there was no damage. Had my welder cut the old one off and weld this one on and it works perfectly.


Worked out great for our replacement


Etrailer was quick, affordable and fast. Great product, had to replace jack on livestock trailer that rusted out.


This is very heavy duty, you can jack up your trailer with the equipment on.


It on one of our equipment trailers and is great has worked flawlessly since installed a year ago


Delivered as promised, customer service was excellent


Easy snd fast good service


Great service. I can always depend on eTrailer. Thank you!


Nice quality product and shipping time was great. Would highly recommend purchasing from etrailer.


Works great!

  • Similar Jack to Bulldog 10k # BD182304 That Has Spring Return Leg

  • Replacement Jack Handle With Vertical Clevis for Gooseneck Trailer Jack
    The Bulldog Replacement Sidewind Jack Crank Assembly # BD015181 that you referenced does have the vertical clevis you indicate was on your original. This handle is intended for Bulldog's heavy-duty square jacks, like # BD182804. If you can provide the brand and part number from your jack tube I'll be glad to confirm the correct replacement handle for you.

    What you would need is a Bulldog Square Jack # BD182804. This jack has the handle on the same side as the pull pin for the jack extension and should be exactly what you need. I attached a review video for this product for you to check out also.

  • Replacement 10K Capacity Jack for Pace Trailer
    I wasn't able to find any information about the jack part number you provided. We do offer some 10K capacity Bulldog jacks, but they aren't A-frame models. We offer a direct weld-on drop leg model, part # BD182804 or a fixed pipe mount, part # BD182524 that would work well for you. The pipe mount is sold separately as part # BD005122.

  • Difference Between Bulldog Landing Gear Jacks BD182800 BD182805 BD182804
    The most similar two jacks you mentioned are the part # BD182800 and # BD182805 with the difference being the side of the leg the jack foot release lever is on which is determined by which direction the jack goes when cranked. These are both basically follower jacks to the # BD182804 you also mentioned which has the main crank handle. The follower # BD182805 would be ideal on the right hand side of the trailer and # BD182800 for the left.

  • Recommended Landing Gear For Stabilizing A 2004 International 4300
    The best option we will have is the Bulldog Square Jack - Drop Leg w/ Spring Return # BD182804. This has a 10,000 pound lifting capacity and a 12,000 pound static capacity. As this is the capacity per jack, you can add the Bulldog # BD182805 to the other side of the frame to double the capacities. You will need to fabricate a bar to connect them, but I think this will be the best option we have for your 2004 International 4300. Now the most heavy duty option we have will be the Bulldog...

  • Availability of Cross Shaft for Use with Bulldog Jack BD182804
    We have the fixed cross shaft extension tube part # BDCS730300 which could be used to extend out the crank of the Bulldog Jack part # BD182804 that you referenced. This shaft is 72-3/4 inches long though which might be too long depending on the width of your trailer.

  • Powered Bulldog Jack Recommendation for a 24 ft Flatbed Gooseneck Trailer with Camper
    The best recommendation I can give you would be to replace your current jack with a Bulldog Jack like our part # BD182804 and then get a Bulldog Powered-Drive Kit # BD1824200100. The powered drive kit is only confirmed to fit Bulldog jacks so you would not be able to install the kit on your current jack.

  • Dual Jack Landing Gear for Gooseneck Trailer Transporting Large Water Tank
    The weight of 1600 gallons of water, without the water tank's own weight factored in, is about 13,350-lbs. For such a high-weight application I suggest Bulldog Square Jacks # BD182804 and # BD182805 along with Connecting Rod # BDCS730300. Two jacks are definitely the way to go. If you wish to motorize this jack setup you can also add motor kit # BD1824200100. I also recommend you first determine the actual pin weight of the loaded trailer so that you can be sure to select jacks with high...

    We do offer repair kits for many jack types, brands and models but we do not have a way to look up the specific brand and model of jack on your 2000 Sundowner gooseneck. From my research it appears most of the 2-horse gooseneck trailers from Sundowner used a single square jack, like the Bulldog 10K square jack # BD182804. This is a weld-on jack. We also have a Bulldog bolt-on 12V electric jack, part # BD185400 rated for 12K. If you can find brand and specific jack model information on...

  • Will Ultra-Fab Motor Kit Work On Bulldog Square Drop Leg Jack
    It sounds like you have a Bulldog Square Jack, part # BD182804, and want to add a motor. The correct powered drive kit for the # BD182804 is part # BD1824200100. This is designed to fit Bulldog, single-speed jacks with 4 inch square tubing and with a 1 inch shaft. The Ultra-Fab Motor and Switch Kit, part # UF17-943045 is not designed to work with the Bulldog jack. The Ultra-Fab Motor is designed to fit landing gear sets with connecting rod and up to a 6,000-lb capacity.

  • How to Remove Pin in Handle Shaft to Replace Gears on an Older Bulldog Model 12 Square Jack
    I spoke to my contact at Bulldog who said that the Model 12, 180 Series Bulldog jack that you have is the older version of the the current 10K jacks like part # BD182500. Since you have the older version without the spring that you mentioned seeing in other videos it means that pin you are trying to remove has knurls on it. When it was first installed that pin hole was smooth and the knurls on the pin basically "carved" into that pin hole. To remove it you need to use a punch and quite...
