Is this right for you? Product Expert Mike S says:

Yes, if you:

  • Don't need the extra reach - and extra expense - of a drop leg
  • Want more protection than a standard 1-year warranty has to offer

No, if you:

  • Own a tall truck and don't want to have to waste time and effort fully cranking the jack
  • Would like to avoid having to do any messy and time-consuming maintenance
  • Want a finish that will last

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.

Average Customer Rating:  4.8 out of 5 stars   (407 Customer Reviews)

Ideal for multiple agricultural and commercial applications, this standard A-frame jack features an 8-5/8" retracted height and measures 14-3/4" from the mounting bracket to the top, excluding the handle. Base sold separately.


After the gears on my original/stock A-frame sidewind jack had stripped and failed (BAL 2000 mounted on my 2017 Forest River Rockwood mini-lite model 2306 with a dry weight of 4005 lbs), I replaced it with another BAL 2000 sidewind model which lasted less than 6 months before the gears also had stripped and failed. After reviewing numerous A-frame jack sidewind models, I decided to purchase the Bulldog A-frame sidewind model with a rating of 5000 lbs and a 15" lift. I also purchased the corresponding foot pad to help with the distribution of weight. The installation was straightforward and simple and so far, I have not experienced any functional issues with the jack. For anyone searching for and in need of a high quality and capable A-frame sidewind trailer jack, I would highly recommend this particular model.

After a year and numerous off-grid camping trips later, the Bulldog A-frame sidewind model is still performing strong. In fact, on one outing, the jack had slipped off a leveling block that I had not properly centered and fell to the ground onto the foot pad. I actually feared that the weight of the trailer would cause the gears to strip and fail but much to my surprise, that did not happen. To me, that is a testament of a well built and high quality product, one that I would still highly recommend to anyone who is considering replacing their stock A-frame jack sidewind model. Additionally, I would also give props to e-trailer for the positive purchase experience I had. Their staff and product reviews are the best in the business.

Stock trailer jack been hard to work for long time. Finally gave up. Scary fast delivery, bolt on in minutes. Works great. No more fighting that damn jack.

perfect holding up nicely. i have a lot of weight in my trailer and the jack still performs like day one
Glen M - 12/10/2021


Replaced the 1500 factory supplied A-Frame jack because it would not lift my trailer ant TV when easing tension on the weight distribution hitch (Blue Ox Track Pro). Plentiy of leverage to lift heavy weights, and the jack is very solid. Hills, extended heights...all no problems. BTW, I tow a 4500 lb Airstream with 550 lbs of tongue weight.


Better than the one that came on a brand new flag staff Mac. it lasted two camping trips before I bought yours. Bull dog is still going strong no problems

Its working flawlessly. Its the jack they need to put on the camper to begin with. The cost was 25.00 more than the one i through away.

Simple installation, just what I was looking for.


Once I decided on the tongue jack I wanted, I placed my order with etrailer. The ordering was easy, shipping was prompt and the jack was delivered a day earlier than expected (even considering the Christmas season and the pandemic).

Installation was honestly a 5-minute task: raise the old jack, remove three bolts, remove the old jack, drop in the new jack, replace bolts. Perfect fit! And the Bulldog jack is certainly much beefier than the one I replaced. The jack is for a 2018 Casita Liberty Deluxe.

If I were to order again, I’d probably opt for the zinc Jack as I believe over the years it would hold up a bit better to the elements.

All the jack dimensions provided by etrailer were a tremendous help in determining the size of jack to order.

Overall, a great purchase experience with eTrailer.


I purchased this to replace a trailer jack that had broken when I was packing up to leave my campsite. I had to ask the campground's maintenance dept to help jack my trailer up and onto my pickup so I needed a replacement jack quick in order to continue to tow the trailer on our next trip. I was happy to find what I needed at etrailer. The gray color matched my trailer tongue and supported more than enough weight. I also needed a side handle as the top handle was in the way of my propane tanks. The install was quick and the jack works great so far. Highly recommend it!


I was really happy with you guys that's why I came back to you'all. Tha foot that I ordered came with the wrong pin in it ( it was a 1/4 inch pin it should have been a 3/8 inch pin ) so I called it in. No problem the proper one is on the way! Thanks for the prompt order, shipping, and correction on the pin issue. Nice to see stuff NOT made in China too! You guys are OK Bruce


The service and help at etrailer has been awesome! The Jack is replacing one that is slightly lighter but this one is a sidewinder vs the one I had, which was a top wind. The equipment seems heavy duty and sturdy. When sliding it through the trailer tongue, though, it needed to be tapped a bit to get it through the lower hole. And I agree with my salesman, that the 5000 lb jack is very light to use and turn. I might have to add pics at a later time.

It is great. It solved the problem of installing a bike rack and rotating in front.

I have a 2009 Rockwood Freedom pop-up camper, I needed a new trailer jack and wheel. Great customer service got me setup with a strong jack and sturdy wheel. Very easy install, I had to grind the bottom steel plate slightly, then it sliide down nicely, aligning up with the three bolt hoes. Very pleased with the two products. Thank you.


Replaced failed problematic electric jack. Installation took 20 minutes. Jack works great as advertised. I expect it to outlast my trailer and truck and even me.


This jack is supposed to lift 5000 pounds. My tongue weight is about 500 lbs. It barely gets it off the ball. The gears are clicky(rough) and the handle is too short to get any leverage. The original Atwood worked much better, it had a longer handle and the gears were smoother. I need a sidewinder and couldn't find the Atwood to replace it.


This is still working well for me it is very strong was easy to put in. Would be great if it could go a couple of inches higher but I use extra blocks under the tongue when on hills. Realize it’s probably not meant for an RV but a flat trailer


The jack was in the same box as the baseplate and the wheel, which were not wrapped in any thing and the paint on the jack is terribly marred. There was enough padding in the box but the lazy shipper did not wrap either of the two separate pieces, or event the barrel of the jacK!.

Customer Service will reach out to you.

I haven’t put it on yet it’s been raining but it’s just what I ordered it got here quickly


Both parts arrived in a very well done package. After years of fighting with the old jack it is nice to finally have one that works great. The caster wheel works for alignment when no spotter is available. Close, but no cigar sometimes can be a pain. Now I can push the trailer to attach the ball when it is off a little bit.


Works great


Really Tuff and Heavy Duty I would definitely recommend


Great working jack. I change out my original jack because of a clearance issue and went to the bull dog front crankIng jack instead of the top cranking jack.


This is a great jack I put it on my 14' enclosed construction trailer. The jack bolted right on and I have had no issues. I will always use in the future.
Their customer service department is very helpful.


Product and shipping were as promised with on time delivery, I liked the sidewinde jack as have less problems and do not get moisture (causing rust problems) as with last two jacks I had too replace after 3 years on two trailers I bought new. The jack was easy to replace (about 20 minutes).

it has worked out quite well with no problems
Todd H - 07/30/2021


does its job but the jack wind handle is oriented to the front. i have a short tounged trailer & there is no room between handle & tailgate to get proper leverage to wind it up & down.its a real workout to jack up trailer, i dont think its geared properly for my setup.


Excellent service as usual. Shipment arrived when described and product was a direct replacement for the Bulldog 3000lb jack.


This fit perfectly on my trailer and was a great upgrade from the jack that came with the trailer


great quality and works well.
