Video Transcript for Bulldog Trailer Jack - Side Frame Mount Jack - BD190754 Review

Today, we're going to take a quick look at the Bulldog Square Jack with footplate, part number BD190754. Bulldog covers this jack with a limited five-year warranty and has a static capacity of 8000 pounds and a lift capacity of 5000. It's a sidewind jack with the handle and the knob on the side of the jack. There's a nice grip so you can get a hold of the jack to make operation easy. The outer tube is finished in a gray paint and the two inner tubes as well as the welded footplate are zinc plated to protect against corrosion. Now, this footplate is going to provide a broad flat surface for supporting the nose of your trailer, which is going to give a good stability.

Now, I want to go over a couple of measurements. We'll measure the jack's retracted height from the top of the jack to the bottom of the footplate, and that measurement comes to about 25 inches. Now, we have the same jack here, but we've got it extended all the way out. Again, we'll measure from the top of the jack to the bottom of the footplate, and we'll get about 40 inches. Now, the difference between the two, 15 inches, is known as the jack's lift or travel.

Now, this is a drop leg setup where you can remove this pin and drop the inner tube down. That way you can make contact with the ground center and you won't have to crank as much. The drop leg feature adds another 13-1/2 inches of travel. Overall, if you had the jack extended all the way out with the drop leg all the way out, it will total 53-1/2 inches in length. Now, we'll show you how to use the drop leg system.

We'll remove the safety pin and pull out our drop leg pin then we can extend the innermost tube. There are pin holes along the way so you can drop it to the point closest to the ground. Again, there's 13-1/2 inches of travel along the drop leg, but we'll just measure from one hole to the next real quick. Each hole has a space about 3-1/2 inches apart. The jack is a direct weld design, meaning you can weld the jack directly from the housing to the frame of the trailer or you can select whatever hardware you might want to use to do the same.

And that's it for our quick look at the Bulldog Square Jack with Footplate, part number BD190754.

I called in for support regarding this product, replacing a bulldog 2,000lb sidewinder jack originally supplied on my trailer. I wanted to upsize to this larger unit as the previous one was barely adequate. I discussed the dimensions and availability in stock. etrailer support was very helpful with the specs and ordering process. I received the item quickly and was exactly as presented at a great price. I cut the bracket from my old unit, mig welded it onto this new unit and it works like a charm. Definitely a positive experience. Highly recommended to buy from etrailer! 405028

  • Electric Side Frame Mount Jack for Boat Trailer
  • Congrats on your new boat and trailer and while there is an electric side frame mount jack, there is not a conversion kit that will allow you to turn the Bulldog Square Jack # BD190754 into a 12 volt jack. The best (and only) option to use an electric side frame mount jack is the Fulton XLT Powered Drive Trailer Jack - Drop Leg - Side Mount - 22" Lift - 2,500 lbs # F141401.

  • Difference Between Pro Series Trailer Jack # PS1400800383 and Bulldog Trailer Jacks
  • I have not heard of any complaints from customers about the Pro Series Trailer Jacks. The # PS1400800383 jack features a zinc plated inner tube and the jack is constructed of steel. The Pro Series # PS1400800383 is comparable to the Bulldog Square Jack # BD190754. Both of these jacks have similar construction and have the same weight capacity of 8,000 lbs. The main reason for difference in price points for each jack is the warranty on the jacks. The Pro Series Jack has a 3 year warranty,...

  • Comparing Bulldog and Pro Series 8K Trailer Jacks
  • The Bulldog jack # BD190754 is comparable to the Pro Series jack, # PS1400850383, that you have referenced. They have the same specs, lift height, and capacity. Both are sidewind jacks and are designed to be welded on. The Pro Series jack has a high customer rating. I think you will be happy with its performance.

  • What is the Difference Between Lift and Support Capacity on a Trailer Jack
  • The support capacity is how much a jack can hold whereas the lift capacity is how much a jack can lift. The Bulldog Square Jack w/ Footplate part # BD190754 has a 8,000 lb support and 5,000 lb lift capacity. If you will be using the jacks to lift and lower a trailer onto a hitch ball or kingpin then they will need to be chosen according to their lift capacity but if you are just using them to stabilizer or support a trailer then they can be chosen according to their support capacity.
