Video Transcript for Bulldog Trailer Jack BD151443 Review

Today we'll be reviewing part number BD151443. This is a Bulldog Round, Snap-Ring Swivel Jack. It is a bolt on installation and it has a top wind handle with ten inches of lift, and it's rated at two-thousand pounds. This dependable jack is recognized as industry standard for agricultural and commercial applications. It's ASABE compliant. It has a convenient, spring-loaded plunger pin swivel feature that's going to allow you to swing the jack up into a stowed position during travel and you can move it back into an upright position for use and support of your trailer. All you need to do is pull the plunger pin and then the mounting bracket is going to be mounted to your trailer, so that's going to hold tight. And once you disengage the pin, it's actually going to allow you to swivel the jack forward or backward into whatever position you need it to be in for your application. This does have precision fitted parts that are going to provide exceptional stability and reliability.

The top wind handle has as smooth, ergonomic design for easy cranking. And it's going to provide us with a radius of six and five eighths of an inch. Another great feature about the handle is when it's not in use, you can actually fold it over into a stored position and free up a little bit of space at the top of your jack. The outer and inner tube has a nice, gray paint finish and that is weather resistant so it's going to stand up well against the elements. Again, this is a bolt on install so the bolt on mounting bracket does include all the hardware. A few additional accessories that I want to show you that are not included with the purchase of the jack: We have the caster wheel assembly. This is available and sold separately with part number BD500245.

Your jack would fit into the wheel assembly and then you'd secure it with the included pin. The other accessory is the standard foot plate. This is available and sold separately with part number BD018564. It's going to install the same way and you would also use the pin and clip to secure it in place. When the jack is fully retracted, we have a bracket height of eleven inches - that's measuring from the center of the mounting bracket to the base or the bottom of the inner tube of our jack. When it's fully extended, that measurement is going to increase to twenty-one inches. If we subtract those measurements, we're left with ten inches and that's where we get our lift measurement from. This is going to provide about four inches of clearance from the center of our mount to the top of our jack.

This is designed to fit a three inch by four inch tongue. The tubing diameter here on the outer tube is going to measure two and one quarter inches and on the inner tube it's going to measure two inches. And the plunger pin here has a diameter of a half inch. Now this jack has a lift capacity of two thousand pounds. Some of the additional measurements that I would like to go over for you are the measurements here located on our mounting bracket. We have the top two holes and the bottom holes.

The internal four holes are for our plunger pins, so we don't have to worry about those. The distance between the top two mounting holes, from the center of one to the center of the other, we have a measurement of five and three eighths of an inch. From the center of our bottom hole to the center of the top hole we have a measurement of four and three eighths. From the center of our bottom to the center of the bottom top hole we have a measurement of three and three eighths. Which leaves us with a distance between the top two mounting holes of one inch. That's going to complete today's review of part number BD151443. That's the Bulldog Round, Snap-Ring Swivel Jack, rated at two thousand pounds. .

I needed to replace my utility trailers jack after it was damaged when someone backed into it and I needed it fast. I was searching the web and stumbled onto I was able to find what I wanted thru the detailed description of the jack I purchased. The ordering process was a snap and to my delight they upgraded the shipping at no extra coast to me so I received my order a couple of days ahead of schedule. It arrived on time and in great shape and the installation was just as it was described on their site. Great job, will defiantly do business with them again. 57766

the trailer jack on my trailer was in the way of me putting my tailgate on my truck down so, I buy the bulldog trailer jack . I like how easy it is to install on the fame rail of my trailer. It is easy to use to lift and lower on to the hitch ball. I like the trailer jack swing up and out the way. The new trailer as solve the problem so I can put my tailgate down on my truck now. 30841


I have the same problem on my trailer. My trailer is 3200 at full capacity and is a camper. Have you had any problems with balance of your trialer or it shifting? thanks!

Moving from an A-Frame jack to a side-mounted jack should not cause any real issue with stability when you have it parked. Just keep the jack as close to the A-Frame. You probably have stabilizers at the back of the camper and they should be able to hold everything stead even if you got with different jack location.

A+ to as they are awesome with service and prompt shipment! 23274

great jack I replaced my A Frame jack with this one because of low ground clearance. I did the trick. Only issue I had was the bolts were too long and I had to replace then. 3251

  • We have several options for a bolt on swivel jack for your trailer with 2 by 5 inch frame (see link). I would recommend the Pull Pin, Easy Swivel Trailer Jack with 8 inch Wheel - Sidewind - 1,500 lbs. by Dutton-Lainson, item # DL22800, for your trailer if the 1500 pound capacity is sufficient for your boat and trailer. These jacks are high quality and designed to fit square tongues up to 3 x 5 inches. The Bulldog Round, Snap-Ring Swivel Jack - Bolt On - Topwind - 10 inch Lift - 2,000...

  • Availability of a Bolt On Swivel Trailer Jack That Can Accept a Wheel or Footplate
  • I believe I have a jack that will work for you application. Take a look at the Bulldog Jack, # BD151443. This jack is actuality designed to accept either a wheel, # BD500245 (for 2 inch tubes). Though the tubing size is 2 inches, I cannot recommend modifying jack # DL22300, or any jack with a wheel or footplate welded on, as it will void the warranty and make the capacity unknown.

You are thinking of a jack like # PS1401140303 but it does not get bolted on, it is a weld on as well and does come with the plate that gets welded on to the trailer. For a bolt-on you would use # BD151443. The brackets are included and it will fit up to a 3x4 inch trailer frame. There is no...

  • How to Pick Out a Trailer Jack for a Boat Trailer
  • The best way to pick out a jack is to pick out one that has enough capacity to handle the tongue weight of your trailer. Typically, tongue weight is 10-15 percent of the total weight of the trailer. So lets say your boat and trailer weight a total of 10,000 lbs. Most likely you would have a tongue weight of 1,000-1,500 lbs. Without knowing your tongue weight but knowing the weight of your boat I think a 2,000 lb jack like the Bulldog Round Jack part # BD151443. Review video attached....
