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 ordered this replacement jack for my horse trailer after my current jack gave out. I ordered a stronger one and was able to install it no problem. I did have to get a special tool for the rusted bolts but after that was easy. I use a Class IV hitch system and with the new jack is easy to lift the truck and trailer to attach the stabilizer bars.

After damaging my old jack stand beyond repair, I carefully researched the internet to determine what seemed to be the best brand available for my replacement. It became obvious that the most recommended brand was BULLDOG. Upon receiving and installing the new jack stand (along with a new caster), I know for sure I made the right choice. Love everything about it, could not be any more pleased. Far exceeds the quality and design of the old jack stand that I used for app. 10 years. Thanks for this fine produce and I would highly recommend it to anyone looking for a replacement. Purchased the jack and caster from and here again, can't say enough good about the service I received. Very fast shipping and excellent packing. Thanks very much

Beautiful! Arrived quickly. Very sturdy. Well packed for safe transport. Can’t wait to install.

- BD155033

Extremely High quality replacement for cheap original equipment jack that came with my RV camper trailer. Easy to use and is well constructed. My only complaint is that the jack is grey and I had to paint it black to match my trailer. I took time to tape off the Bulldog decal and paint around it but the decal faded in one year.

Working great. Works like new even though it has been sitting out in the weather. Faded decal is my only issue.

Great replacement jack for my pop up camper! I could not find one that would not drag on such a low frame, but etrailer had what I needed. Since it is an old camper, I had to ream the hole in the trailer to 2 inches, but gained a lot of stability.

- BD155033

Excellent quality, very sturdy and easy to operate. Exactly as advertised. Priced well. etrailer did a great job getting it to me.

- BD155033

Simple 3 x 5/16" x 1"bolt, triangle shaped bolt on for the jack. 3 second 2" tube slip on and safety pin for the foot plate.

- BD155033

Excellent replacement jack for my Carry On trailer. Timely delivery and easy to mount.

- BD155033

Perfect nice to see a company working hard for the customer again keep up the great work

- BD155033

Works perfect and fit through the tight space on my trailer. It functions so smoothly. Definitely a nice replacement for my damaged one.

- BD155033

Haven’t put it on yet but looks good and the packing was great Great Company!!

- BD155033

I had looked for some time for a replacement trailer jack for our pop-up camper. I was surprised at how expensive they were. E-Trailer's websie offered a couple of great options and this one was perfect. It was easy to install and works better than the original that came with the pop-up. I've been very happy with it!

- BD155033

The jack arrived on time and is installed and works very well. UPS had been very rough on the package but the jack was just fine. I bought it to improve the retracted ground clearance and it works exactly as I hoped. The service from etrailer and the sales person I talked to was terrific.

Great! I really like the fact that it retracts flush with the trailer frame and is smooth and easy to use. The paint is fading a bit but that doesnt affect the great operation.

Great quality jack and provides for a variety of attachment options. I combined this with the e-trailer drop leg (13-1/4") to provide about 28" of lift. Oddly, the equal Bulldog drop leg did not slide in as smoothly as the e-trailer drop leg.

- BD155033

The trailer jack I ordered originally did not fault. The rep that assisted me was extremely helpful and pointed me to the correct product. Even though it was after the 3 pm cut off for UPS, the rep went above and beyond and got the correct product out the door. I received the next day! Installation was easy and the jack works smoothly. Customer service A++.

- BD155033

Exactly what I needed. Still working perfectly. Very little hangs down below the hitch which keeps it from running into the ground while going through dips and driveways.

- BD155033

Bought this piece to give me a bit more ground clearance on my enclosed cargo trailer for steep ramps and such. Delivered in record time and well packaged. Looks like it should do the trick. Just need to get the old one off, and install this new one.

- BD155033

Product just as ordered.

- BD155033

bought to replace bent unit on Cornpro trailer. P/N listed as a direct replacement but actually was slightly taller thus retracted further - completely up into the trailer frame which eliminates chance of bending it if trailer nose bottoms out in rough terrain as before I am extremely pleased with this design improvement

1 year later - still like new condition. well designed and works great ! !

Quality part. Used Bull Dog jacks in the past and like the fold down handle design. Never had a problem with one yet.

Well lets say it is tough enough to make up for me not remembering to make sure it was all the way up.... Still working after that abuse!

I purchased this product as it retracks much farther than the one that came with the trailer. The old one dragged when the truck/trailer V'ed down when going through a dip. This one gives plenty of clearance and we have had no problems.

After a year of use there has been no problem with this Jack. It still cranks like new and there has been no dragging when going through gutters.

I have an older, at least 4th hand, slant 3 horse with tack room trailer. I needed a new jack as the bearings gave out on the original. The Bulldog was easy to install, and has been working smoothly for the past year. I should have done it five years ago.

I stand by my review from a year ago. If youll pardon the pun, it is working perfectly, without a hitch.

Trailer jack is just what I ordered, was a good value and arrived earlier than expected. I'll be shopping here for any of future trailer parts first!

- BD155033

I wish it had more lift. It won't quite raise the trailer high enough to clear the ball on a Honda Pilot, so not a high hitch. My fault for not measuring better and it isn't a huge deal; I can just put a block of wood under the foot. Otherwise it seems to be well constructed. The handle folds nicely out of the way and the pivot is stiff enough to not bang around while you're driving. Bolt holes lined up with the holes on the trailer. I used bolts in case it ever breaks; angle grinding the old one off that had been welded on was a chore.

- BD155033

This was my third purchase from etrailer. Their service and product catalog are among the best! They provide excellent tracking info after the product is shipped. I'm happy with the quality of the Bulldog A-Frame Jack. It's well made and sturdy. I purchased this jack because the jack installed by my trailer manufacturer was too long, causing the wheel to drag when moving the trailer to/from an uphill grade. If I could change one thing it would be to make the outer tube just 1" longer below the mounting plate; to provide better support when the jack is extended. Otherwise, all is well.
