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.

Bulldog jacks used to be made in Wisconsin. Now they’re made in China and it shows. Material is far less robust and the neck below the flange is an inch shorter (3 1/4” vs 4 1/4”) making it unusable on my old Logan trailer. The neck doesn’t extend through the lower brace. I’d give it a lower rating but, in fairness, it’s probably “industry standard” for today and would have worked adequately if the neck was longer. I will have to return it.


etrailer is a great company to order from. I am able to find what I need and the sales team does a great job of communicating information. Carol C. did a great job of letting me know when my order was received, shipped with tracking information and let me know when it was delivered. Thank you etrailer.


Exactly to Jack I needed. The short length from the collar to the bottom end allows he Jack to retract to a length that it is not below the trailer hitch where it won’t catch on. Something. And bend.



The jack is still performing as needed. Glad I found it.

@Ralph We're happy to hear that, thanks!


Item was as advertised, well packaged and delivered on time.


After owning an old jack for so many years I bought a new jack. I have had this Bulldog replacement for over a year and the jack is so easy to use and does not need a ton of muscle to get the trailer up and down. It still looks brand new and I love the red knob!!!


Perfect fit. This gives me more clearance than the jack that came with my little cargo trailer. It also gave me the room to slip on a jack wheel when I need it.


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


Product was better than expected, shipping and communication were outstanding. Need trailer parts, this is the place to go.


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


Love this that has plate so it retracts to the AFrame instead of permanentwheel like my prior one that left the wheel retracted low enough I felt was unsafe, my one advise would be get the plate AND the wheel, plate allows good retraction but not great for parking, wheel gives better support and safety in parking trailer unhooked. Apparently there are no safety chocks for plates if you need.


Perfect for my application and excellent product. The only issue I had was the original delivery date was not met and I ended up receiving it 3 days later.


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



My Bulldog trailer jack continues to work very well. What you expect from a Bulldog product.


Product was as advertised and delivered in a timely manner.


Product is exactly as pictured and desc ribed


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.

Peter G.


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


Sturdy, fit perfectly, operates smoothly. Shipping was quick.


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.

Tom J.


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


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.

John C.


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.


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.

Tim M.


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.


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.


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.


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.


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!
