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.

Review from a similar BD A-Frame Jack in Trailer Jack


Very sturdy construction. My light duty round jack failed in my camper and needed to be replaced. I always wanted a drip leg instead of using blocks. I had t cutout a square hole but well worth the extra effort to have a heavy duty jack with a drop leg. Thanks again to etrailer for excellent pricing and fast free shipping.

Very heavy duty and well built jack. I installed this to accommodate close clearances to a toolbox, and couldn't use the existing topwind jack. Very smooth motion, even under load.

This is the second jack that we bought from etrailer. The shipping was fast, with in one day of ordering, and it bolted right on. The order process was super simple because the etrailer's website had all the information on it to be able to find the right jack for our needs. I did have a question so I used the live chat feature and with in seconds I had my answer. I wish every website was as easy to order form as etrailer's.

Review from a similar BD A-Frame Jack in Trailer Jack


Thank you for your inquiry. I just yesterday found time to install the Bulldog jack. The package shipped and was delivered earlier than promised, which was a pleasant surprise. I was impressed with the quality of the jack just taking it out of the box. I am more impressed with it on my trailer (Boatmaster with 17.5 Key West Stealth). It operates smoothly and with minimal effort. I chose to store the boat trailer on blocks rather that use a jack wheel as the wheel hangs too low when towing and installing and removing it is just another task I prefer to avoid. This jack replaces one ten years old used primarily in a salt water environment. It is a very good product. I did attach a picture of the jack.

Review from a similar BD A-Frame Jack in Trailer Jack


I have a 16 foot galvanized car hauler trailer with the A frame type mounts at the rear on each side for stabilizing jacks. These fit the bill perfectly and at 5k each will handle anything I tow. I could have gone with a couple 2k jacks at half the cost but I tend to over-engineer things to handle worse case scenarios. I don’t haul more than 5k pounds so if one failed the other could handle the load. I wanted zinc for corrosion resistance. I added the square bulldog footplate to each one. The top wind has always been much easier and more durable for me so I favor that over sidewinder types.


Comments
Still work great, even after the trailer was stolen and one foot plate retaining pin was ripped off when I recovered it. A couple bucks at tractor supply for a new pin and it still works like new. One tough jack!

Unlike the original jack that came with my boat and trailer this jack has the strength and gearing to effortlessly raise the trailer tong off my hitch.

Jack is still as strong as the day I bought it.

Review from a similar BD A-Frame Jack in Trailer Jack


I needed a trailer jack for an A-Frame trailer that would provide more clearance for uneven terrain and driving over curbs. The etrailer website was so easy to navigate and find a jack to fit my needs. The details related to each hitch were very clear and detailed. Once I selected a jack, the product was delivered promptly and was exactly as described. I would definitely recommend etrailer.com to anyone looking for trailer jacks and accessories.

Have been using the jack for a year now and it works great

Review from a similar BD A-Frame Jack in Trailer Jack


I love this design. The installation went great until I tried to attach the foot to the end of the stem. The stem would not fit into the foot. So I am waiting for a new foot to match this jack. :( The bolt holes lined up perfectly with the threaded holes in the trailer tongue. The only other features I would like to see for this product would be a waterproof cover to place over the top of it to keep water out of it and a grease fitting to lubricate the gears.

Review from a similar BD A-Frame Jack in Trailer Jack


Product shipped in an extremely timely manor and arrived undamaged due to the quality of packaging. This Jack fit the front of my travel trailer (not commercial) just fine and only took minutes to install. My local trailer parts store was selling tongue jacks of half the capacity for nearly double the price. This was an awesome find and I'm glad i chose etrailer for my purchase. I did not rate 5 of 5 only because I have not had a chance to operate the jack.
