How to Determine the Lift Capacity You Need in a Jack

A trailer jack is designed to lift the tongue of your trailer so you can connect the trailer coupler to your hitch ball. To do this, you'll need a jack with a lift capacity high enough to handle your trailer's tongue weight.


Tongue weight is the amount of weight that your trailer applies to the back of your tow vehicle. Typically, your tongue weight should be 10-15% of your total trailer weight (trailer + cargo). In other words, a 10,000-lb trailer would have a tongue weight between 1,000 lbs and 1,500 lbs. For a trailer this size, you would need a jack with a lift capacity of at least 1,500 lbs.


It's okay to have a jack with a weight rating that is higher than your trailer's tongue weight. In fact, a jack with a higher lift capacity should operate more efficiently, allowing you to spend less time cranking and more time camping.


Trailer and Camper Jack Lift

Every jack offers a certain amount of lift or travel. Screw travel is the distance the jack extends when you crank it (or toggle it to "extend" on an electric model). Some jacks include a drop leg for extra adjustability. On these jacks, you'll see the maximum extension of the drop leg listed in the specs as well. Adding the screw travel and drop leg travel together will give you the total lift. The total lift listed above can help you determine how high this jack will be able to raise your trailer.

I over loaded my work trailer broke the stock 2000lb trailer Jack. I needed a quick replacement and found your 5000lb Bulldog A-frame. The price was great and I got it in 4 days. It took less than 5 minutes to install and its such a better quality. It spins smooth and easy with just my finger. It's everything you say it is, I'm very pleased, thank you

Review from a similar Top Wind A-Frame in Trailer Jack


Although most trailers come with an A-Frame Jack, if I damage the jack or want to replace the bottom-of-the-line included jack, I prefer the Bulldog 5,000 lb jack. The jack is very stout, works effortlessly for as long as I've owned any trailer and never needs to be greased. In addition, it is designed to accept a flat foot attachment at the bottom or one of Bulldog's outstanding wheels.

Thanks for the follow-up. All the products I purchased are performing wonderfully!

Put heavy duty jack on car hauler. Handles trailer with 3/4 ton 4-wheel pickup as a load. Good enough for me.

Review from a similar Top Wind A-Frame in Trailer Jack


In addition to this support plate, I ordered a Bulldog Jack and a foot plate. During my prepurchase research, completely frustrated at the lack of detailed product information available on most sites, I finely landed on etrailer.com. I found all the information I was looking for, and the pricing was the best I had found, and e trailer offered free shipping. I placed the order and recived a follow up thank you email. The following day I received an update of the shipping status along with a tracking number. I recived my package within a week via 3-day shipping. The care given to packaging was amazing they could have sent fine China in the packaging. I love this place and will order from here again. D.

Review from a similar Top Wind A-Frame in Trailer Jack


Jack seems solid, was a breeze to install, fit perfectly, seems to work fine. Installed on a large, enclosed Scout trailer that hauls a LOT of gear. We'll try it out next weekend. Only gave if 4 stars because we haven't really used it yet.

Review from a similar Top Wind A-Frame in Trailer Jack


Jack works smoothly on my car trailer lifts trailer off the truck with a full size car on it no problem. I would buy it again. I like the folding handle feature as well


Comments
This jack still works as good as the day I installed it on my car trailer. I haul full size trucks Chevy suburbans and tahoes and the jack lifts the trailer up off my truck with the full load on it time after time. I will defenetly buy another one of these jacks if and when this one wears out and needs to be replaced.

Excellent heavier duty A-frame jack. Easy to install, (used the existing holes). Replaced the oem unit that came on my 2007 open car trailer that was way past its duty cycle. This is a hefty unit at a reasonable price.

Works great, smooth action, you can weld or bolt this unit on. Using this on a car hauler. The original one failed after 12 years of use, so I found this one online. It looked just like the one I replaced....hopefully I will get the same years of use from my new one.

  • Where Is Retracted Length Measured On Trailer A-Frame Jack
    The retractable height of a jack like the Bulldog A-Frame Jack, part # BD175000, is the distance from the bottom of the inner jack leg when fully retracted to the mounting bracket. The measurement is taken with no bottom bracket or wheel installed. The BD175000 has a retracted measurement of 12-1/4 inches and has a capacity of 5,000 lbs.

  • Recommended A-Frame Trailer Jack for Bottom Mount Trailer Application
    For your trailer jack, I recommend Bulldog A-Frame Jack - 5,000 lbs - Top Wind # BD175000 which will be an easier installation than a sidewind option on your trailer based on the photos. If you prefer the sidewind style, it can absolutely still be used. For this, I recommend the Round A-Frame Trailer Jack - Sidewind - 15-5/8" Travel - 5,000 lbs # TJA-5000S-B. The installation of a sidewind will require disassembling the jack because the gearbox wouldn't otherwise clear the installation...

    The Bulldog A-Frame Jack # BD175000 does not have a hole in it for a caster wheel or footplate. I talked to Bulldog and they said a hole can be drilled. For a similar jack that does have a hole already we have # BD155032. For a caster use # BDCP555 and for a footplate use # BD018564

  • Recommended Trailer Jack for 2017 Sure Trac Dump Trailer
    For your 2017 Sure Trac Dump Trailers, I recommend the Bulldog Round, A-Frame Jack - Sidewind - 15" Lift - 5,000 lbs # BD1700100317 along with the foot plate # BD018564 for a sidewind option or the topwind # BD175000 if you prefer that style with the same foot plate. These jacks are very well made and have a high tongue weight load capacity of 5,000 lbs when lifting or 7,000 lbs static. Both these jacks have a 5 year warranty.

  • Correct Trailer Tongue Jack Capacity for a Trailer with GVWR of 2980-lbs
    When it comes to either trailer tires, hitches, winches or jacks, having extra capacity is a good idea. With jacks, using one rated for more weight than you're actually going to ask it to lift means it will have to work less hard to do its job. That tends to mean reduced wear and tear and can lead to a longer working lifespan for the jack. Since the cost difference between 1000-lb and 2000-lb jack is often quite small, it just makes sense to add safety margin whenever possible. For...
