Average Customer Rating:  4.8 out of 5 stars   (105 Customer Reviews)

Trailer Jack is all I hoped it would be.
It is easy to use, mounted to my original swivel yoke. No wedding required to replace this Trailer Jack for the original on our 5 foot by 12 foot tandem axle trailer.
Cranking action is smooth and easy to turn with the long handle.
The foot plate easily extends with the quick change pin, reducing the cranking needed to lift the trailer hitch for loading the trailer and leveling our trailer once a destination no matter what the load.
Using an bungy cord to keep handle from hanging down when the Trailer jack is lying in its travel position along the trailer tung.


Comments
The Bulldog Trailer Jack is one of the best investments I made for my trailer. The original Jack froze up in the cold, was either to long or to short. That is I had to dig a hole to set the jack or I had to crank for an hour to get the foot plate on the ground. The Bulldog Trailer Jack has worked in all weather, even at -35C. With the adjustable leg I have never had to dig a hole because the Jack was to long. It only takes a few seconds to adjust the leg length so I only have to crank a shot time to lift and lower the trailer hitch. I love the Bulldog Trailer Jack.

The jack works great! 2 nice features complement its functionality: it’s geared low, so can easily raise a heavy load ( 2 cord wood, 1.5 yds gravel, 30 hp tractor etc), and the adjustable foot can be moved to lessen the travel needed. This extension also make it possible to raise the front higher than nonadjustable jack models. Has given me a higher slope when shoveling out the bed - a quasi manual dump effect.

And last, it is mounted on a rotating bezel - so can be stowed horizontal when towed, if needed. This really helps me when I use it in the woods, towed by the tractor, digging out stumps. It easily clears roots rocks, and deadfall - with the trailer wiring safely tucked inside conduit.

Very pleased after a year, no problems or issues. Has proven more functional than I expected.




by:

Great product. Worked smoothly and exactly how it’s supposed to. Communication was awesome. I was notified that the product was going to be delayed a bit and they even offered another type of jack that they had in stock, if I didn’t want to wait. Definitely appreciated the amount of communication!




by:

The trailer Jack arrived prompt and is of great quality, due to the specific measurements they recommended taking, it was "plug and play".
I am very pleased with the service etrailer provided!

After a year of use it is still like new,smooth and strong!

Product worked great! It’s well made and looks good, easy to weld into place and lifts a car hauler trailer with no problems!
Would recommend!




by:

I first ordered a top wind jack and the winding handle hit my spare tire mount so I called etrailer.com and they helped me exchange it for this side wind one. Jack works great and I love the drop leg. Its geared lower than my old jack so its easy to wind but takes more winds to get it raised up. Great customer service. I will buy from them again.




by:

Perfect replacement fit.
Works great!




by:

Shipping was really fast. Had good tracking and communication throughout. Bought it for my m1102 trailer. Haven't got to use it yet so this is as far as my review can go. I'll come back layer after some good use.

The jack is great. Built tough as hell, and works perfectly.

Thanks for the email . I really like the jack, fits my trailer perfectly.

I could't have made a better choice when I purchased this jack! The trailer that I have is a low profile HEAVY trailer that needed a well made heavy duty jack to match. I have a rental space to store a trailer, and a car. This storage place allows the person to store any vehicle in that parking space that he, or she chooses. My trailer is a car trailer, so this is why I needed a strong jack to match because the car stays on the car trailer for months at a time. This is still weight mind you, and with a car that's about 5,000 pounds heavy! So I'm very pleased with this Bull Dog jack! Thank You etrailer!




by:

The mounting bracket which is part of the jack fits both the external bracket supplied with the jack as well as the smaller existing internal bracket on the machine from the prior jack, a nice touch not to have to cut off my male mount and weld on their larger female mount. My only comment would be that there needs to be a provision on the jack to secure the crank handle when the jack is stowed in the horizontal position. Otherwise, it just flops free and dangles below the body of the jack in the stowed position. Could contact the ground in certain situations.




by:

Just had it welded to our Eagle Spirit trailer that hauls a 24 foot Thompson Fisherman and it is GREAT. Handles the heavy weight with absolutely no problem. Thank you.


Comments
Its working great for us. My husband feels very confident that this jack will hold our big boat.

Great jack. Installed it on my 12 ft dump trailer in no time with the included weld on pipe mount. This jack is Heavy Duty. Install, stow or remove quickly with the pipe mount design. This jack has an adjustable foot, eliminating the use of blocking or extended cranking, and it has a grease fitting. Was at my door within 48 hours of purchase and shipping was included.




by:

First, Amazing service from etrailer, always quick shipped. This jack fit my M1102 military trailer perfectly. The original jacks are a little flimsy for max load but this thing is heavy and sturdy and fit onto the current jack mount with no modifications. The only advice is to let the jack out about an inch or so when stowed in order for the foot pad to clear the frame. When stowed I use a small bungie cord to stow the handle in line with the jack body so it doesn't hang down. Perfect option for these military trailers. This has the convenience of an extendable foot pad which really cuts down on the amount of cranking. Operates smoothly under load.




by:

Well built and heavy duty jack. I purchased 2 of these to use on the rear of my utility trailers so I can load and unload them without being hooked to a tow vehicle.

Being that these rotate and are also quickly removable, I can either rotate them out of the way or remove and store them in the trailer storage box.




by:

It's been installed for a year and is working great!




by:

Fast shipping and great communication. Best price i could find online! I would however urge etrailer to post the ID, OD and Lengths of the pipe mount for each jack in the descriptions. I was only able to get this information by drilling down into user reviews.




by:

These jacks are used on equipment that gets abused they are still holding up well.


Comments
Best decision I made was replacing all those jacks.
Danny C - 02/23/2018


by:

The jack works exactly how I wanted. Its more of a heavy duty jack than what I needed but It met the specifications that I needed. The only minor thing that me personally do not like which is not a big deal is when the jack is parallel to the ground the handle will hang down. I would highly recommend this jack.




by:

I appreciate working with etrailer.com and the excellent customer support. Highly recommend!




by:

Love the new jack. Much sturdier than original equipment that came with the 10,000 lb. trailer.




by:

etrailer did a great job getting this product to us so we could provide this to our customer. Thank you for helping us look good to our customer




by:

We added this to our scout trailer to replace a frame mounted one that froze up. No complaints in the first year.




by:

Great products and service I’m a part time commercial fisherman so my equipment work hard will definitely order from etrailer again




by:

Great quality. Have not installed yet, but it appears to meet the requirements we have.

The jack performs great and is of high quality.

  • How Long Is Bulldog Square Swivel Jack W/15 inch Lift-5,000 lbs When Retracted
    The Bulldog Square Swivel Jack w/15 inch Lift-5,000 lbs Item # BD190758 is approximately 25-1/2 inches long from bottom of footplate to top of jack when retracted. Links to more information attached.

  • Extended Bracket Height of Bulldog Square Swivel Jack # BD190758
    When the Bulldog Square Swivel Jack w/ Round Pipe Mount # BD190758 is fully extended it actually has a bracket/mount height of 41 inches. This is with the jack itself fully extended (which provides 15 inches of travel) and the drop-leg extended to its highest mounting hole (which provides an additional 13-1/2 inches of travel). This measurement is taken from the ground up to the center of the swivel mount tube where it will attach to the trailer frame. I have attached a short video...

  • How Many Cranks Does it take for the Bulldog Jack BD190758 to go 1 inch
    The Bulldog Square Jack # BD190758 that you referenced takes 8 cranks of the handle to extend or retract 1 inch. I went out into our warehouse to confirm this.

  • Dimensions of the Mounting Pipes on the Bulldog Jack part # BD190758
    I went out into our warehouse and to measure one of the Bulldog Square Swivel Jacks # BD190758 we had in stock and found that the inner diameter of the female mount is 2-17/32 inches and the outer diameter of the male pipe mount on the body of the jack is 2-15/32 inches. Yes, the female end does get welded in place on your trailer frame. I attached a review video for you to check out as well.

  • What are the Measurements on a Bulldog Square Swivel Jack # BD190758
    I pulled the Bulldog square swivel jack # BD190758 from our warehouse to provide the measurements you requested. The jack is 26-inches in overall length, not including the handle. The handle radius is 8-1/2 inches for your reference. If the foot base plate is removed the measurement of the entire square outer tube is 24-3/4 inches. The wall thickness of the square outer tube is 0.135-inches. When the outer square tube collar is in the retracted position with the foot included it's 3-inches...

  • Can 3 inch Pipe Mount of Bulldog Swivel Jack Attach to 2 inch Trailer Frame
    Even though you have a 2 inch tall frame to weld a pipe mount to the 3 inch pipe mount that comes with the Bulldog Jack # BD190758 will still attach securely enough to it. You'll just need to have it welded around the mount where it touches the frame and you'll be fine. Your 2 inch pipe mount should still match up to this as a male fitting but the 3 inch mount would be better.

  • Sidewind Jacks Versus Topwind Jacks
    There really is not an advantage to having a side-wind jack versus a top-wind jack. It really just comes down to personal preference and what clearances are available on the trailer. You may find that the handle location would interfere with components mounted on your trailer with one style, but not for the other. In theory you would need to bend over farther to operate a sidewind jack since the jack handle goes up and down. Depending on the height of your trailer this may not be an issue...

  • What Does the Bulldog 3" Long, Weld-On Jack Pipe Mount # BD003155 Attach To
    The Bulldog 3" Long, Weld-On Jack Pipe Mount # BD003155 is generally used for the installation of trailer jacks like the # BD190758. The other side of the mating part is permanently attached to the jack. The matching pin is on the jack as well. Check out the review video I attached for more info.

  • Which Female Pipe Mount Works with Bulldog Trailer Jack BD190758
    Pipe mount # BD005024 is the correct match for Bulldog jack # BD190758. The mating end on the jack fits inside of this mount which gets welded to the trailer frame. I have linked a video of the mount for you.

  • Is There a Bulldog Square Swivel Jack With Round Pipe Mount And Drop Leg
    There is an option with a drop leg that is similar to the Bulldog Square Swivel Jack with Round Pipe Mount - 3,000 lb # BD195356. The other option has a higher capacity of 5,000 lbs, but it is a pipe mount like you are wanting: - Bulldog Square Swivel Jack with Round Pipe Mount - Drop Leg # BD190758 Like the 3,000 lb capacity jack, the 5,000 lb capacity Bulldog has 15 inches of travel, with the drop leg adding an additional 13-1/2 inches of lift.

  • Replacement Nut and Screw for 4 Inch Square Bulldog Jack on a Gooseneck Trailer
    Nut is the term used for that threaded collar inside the jack. And the screw would be the other part. The nut is not available by itself but you can get it with the screw (not a bad idea since there could be damage to the screw as well). If you have a 12K capacity Bulldog jack, 182 series, from 2003 to present then you would use # BD500217. If it is rated for 10K lift and 12K support then you would use # BD500250.

  • Worm Gear Winch Recommendation For Lifting 500 lbs Off of the Ground
    I have a solution for you, but we have had a similar question come in the past and our jack manufacturers cannot recommend you use the leg of a jack as a lift. Your best option is going to be a worm gear winch like the part # DL10954 that can be set up to be used as a ceiling hoist.

  • How is Pro Series PS1400850383 Trailer Jack Installed
    The # PS1400850383 Pro Series Square Trailer Jack you'd looked at is designed to be directly welded to the trailer frame without using a mount. I've linked you to a product description video featuring the jack. If you were looking for a side wind 5K capacity 2 inch pipe mount, I'd recommend the Bulldog # BD190758.

  • Trailer Jack that Doesnt Hang Down Very Far for a Big Tex Utility Trailer
    Depending on the capacity you need I do have some A-Frame jack options you might like. Take a look at the Ultimate Trailer Jack # 322-RDJ-2K. It is more adjustable than other jacks and measures just 1-3/4" from the mounting bracket to the bottom of the leg with the jack fully retracted and the collar at the lowest setting. This jack is rated for 2,000 pounds. A wheel or foot will add more to that 1-3/4 inches so keep that in mind. For a wheel you can use # JC-102. For a foot you can use...
