So far working very well. Much easier than my top turn jack. Easy install taking approximately 2 minutes. 787028

Great jack, I previously had a 2000lb capacity jack for my 3500lb GVW trailer and it didn't have enough strength to smoothly lift the trailer every time. This 3000lb jack does the job. Thanks 732583

- BD1550100317

Great replacement. It took me about 5 minutes to change. I also got the drop leg . What a difference it makes. I will shop here again soon. It got a 4 star only because I don't believe in 5 stars. Nothing is perfect but this came close. Thanks for making it easy to shop and replace my broken jack with a real up grade to my 20 yr. old trailer. Pappy <>< 706088

Nice jack, fast delivery and I am completely satisified. Installed it on my enclosed cargo trailer & it works as expected. Will order from etrailer again. 439928

The tounge jack is also perfect! I am very happy 430060

I am very pleased with this trailer jack. Initially, i was worried that it would not provide the proper ground clearence that I required because of how low my trailer is. Etrailer has a wealth of information, all the way down to measurments when the jack is in the full up position. Installed without a hitch, no pun intended. This jack is great for those extra low trailers and is very well constructed. 380280

- BD1550100317

For the money, it serves its purpose well. It's a jack. As long as it goes up and down smoothly and does not collapse, it's all good. 353821

This BullDog tongue jack is a simple, strong and well-made replacement for heavier applications such with our 7000lb horse trailer. 270847

I bought this to replace a damaged jack on my small camper. I was looking for a jack with a shorter retracted extension since my camper sets low. This worked perfectly. The quality is outstanding. 229009

- BD1550100317

I was disappointed that the jack says Made in Mexico when the website says Made in USA. I have only used it once so far, but it works good and has more ground clearance than my old one. 102030

It was previously made in the US but we did not know the production change had happened. The site will be corrected shortly.

The gearing is very smooth and I was able to swap the handle to the inside of the tongue. 75343

  • Dimension of Bulldog A-Frame Jack From Bracket to Bottom of Tube
    When the Bulldog Round, A-Frame Jack # BD1550100317 is retracted the measurement from the mounting bracket to the bottom of the tube is 7". I have made a photo for you to check out which shows this measurement.

  • Replacement Sidewind Jack for 23 Foot Boat Trailer with Shelby A-Frame Jack
    Trailer jacks only have to lift the tongue weight of a trailer. So your trailer weighing about 4,000 lbs would only have about 400 lbs of tongue weight which the Bulldog jack part # BD1550100317 that you referenced would easily take care of. This matches the style of jack you need and fits the standard a-frame bracket your trailer has so it will fit and work really well. To add a wheel to this jack like what you have now you'll just need the part # BDCP555.

  • Replacement Bulldog Jack # BD1550100317 for Jack On Trailer with Damaged Threads
    You definitely do have a damaged screw and nut in your Bulldog jack # BD1550100317 based on what you described. Since those parts aren't available you'll have to replace the jack entirely or possibly just swap the internals from the new to the old. What happened is that you over-extended your trailer jack which is what ruined the threads of the jack.

  • Difference Between Bulldog Jacks # BD1550100317 and BD1550101344
    The only difference is the finish of the two jacks. If I were you I would go with the galvanized part # BD1550101344 as it will fight corrosion better than the painted version. Most likely it's an issue of that we sell more of the galvanized version, therefore we have larger orders of the jack so the price is a bit better.

  • Recommended Jack For 1998 Rockwood Popup Camper
    From the specs and photos I was able to see for a 1998 Rockwood popup camper it looks like you have an a-frame jack on the trailer. I have attached a link to the a-frame jacks we offer you can check out. If you are looking for a sidewind jack I recommend a jack like the Bulldog Round, A-Frame Jack, part # BD1550100317. This has a 3,000-lb capacity and features a 13-inch lift. If you want a footplate for the jack I recommend part # BD018564 and if you want a caster for the jack you...

  • Jack With Short Retracted Height for Horse Trailer
    The # TJA-5000-B jack has a 10-3/8" retracted height without a footplate so for a 5,000 lb jack with less retracted height, a great option is the Rack'em B-52 Round A-Frame Trailer Jack # RA-29. This jack has just an 8-1/2" retracted height and if you add the Bulldog Detachable Footplate # BD018564 you will be adding less than half an inch to that. If you needed even less height you would need to get a jack that does not have as much lift capacity. The lift capacity only needs to...

  • Round A-Frame Trailer Jack for 14,000 lb Trailer
    We can definitely help you out here, but let's start with the coupler. You mentioned Bulldog Heavy-Duty Cast Head Coupler with Wedge Latch # BD44150WQ317 but that you had a round jack on your trailer. This coupler has a hole for a square jack so instead, I recommend the Bulldog Heavy-Duty Cast Head Coupler with Wedge Latch # BD44150W0317. This is the same coupler but has a round hole for a round jack. Then for the jack, the great thing is that for an A-frame jack, its capacity only...

  • Recommended Trailer Jack Options For 1993 Jayco Eagle Camper
    For your 1993 Jayco Eagle camper weighing 6800 lbs, I am not sure if you need an A-frame tongue jack for a travel trailer, replacement landing gear for a 5th wheel, or stabilizer jacks. The side jack makes me think 5th wheel or stabilizer jack but I will give all recommendations. If your 1993 Jayco Eagle is a 5th wheel trailer, I recommend the Stromberg Carlson Electric Landing Gear Set - Weld On - 34-7/8" Lift - 5,500 lbs # LG-1. This landing gear has a leg length of 29-1/2 inches...

  • Drop-Leg A-Frame Jack for 4500-lb Travel Trailer
    The 2500-lb-rated Square Jack # MJSQ-2500B certainly has enough capacity to lift the 600-lb tongue weight (TW) of a 4500-lb travel trailer although this particular jack is primarily intended for marine trailer applications. This jack's included bracket mounts to the side of a trailer frame that measures up to 3-inches wide and between 2- and 5-inches tall. Since your travel trailer is an a-frame you might consider a comparably-rated a-frame jack like the 3000-lb-rated Bulldog # BD1550100317...
