How to Determine the Support Capacity You Need in Your Landing Gear

Landing gear stabilizes about 25% of your trailer's total weight when it's loaded up. For example, a 14,000-lb trailer has a pin weight of about 3,500 lbs. For these legs to work, you'd need a set of landing gear strong enough to lift no less than 3,500 lbs. And, yes, it's okay to have some legs with a weight rating that is higher than your trailer's pin weight. In fact, they should operate more efficiently, allowing you to spend less time cranking and more time camping.

Note: Do not use landing gear to lift your trailer during tire changes or service work, because doing so will exceed the capacity of the landing gear.

I also received this in a couple days. It is really a good strong
10000 lbs jack. I can’t wait to get it out on.


Jack appears to be fine but packing could use some improvements.


Sturdy and reliable. I have 4 of these on a 20' 12,000lbs trailer and they are driven by hydraulic motors. They are cycled multiple times a day for 8 weeks during harvest season. So far so good.


I Have been using it for a year without any problems.


This is a replacement for the original jack that came with my trailer. I am hard on equipment as I build fences and have to drag across terraces and through stream crossings. I carry a skid steer, four wheelers and attachments. This jack is lower geared than the previous one on the trailer and is much easier to raise with weight still on the trailer...slower, but a great improvement. It's nice to be able to unhook without having to unload all the time!

Eric C.


Still working great! No problems. Great product. Thanks for the follow up


We have been propping up the goose neck flatbed for years. The Bulldog hitch was easily installed, makes hooking up and dropping our trailer a lot easier and safer, and seems better built than the original. Wish we had done this a long time ago!

Pam D.


Still easy to use and holding up well, great purchase!


Nothing wrong with the jack. etrailer has always provided prompt shipping as well. But, as you will see in other reviews, the packaging is terrible. The jack was shipped in a light duty box, and was all but destroyed when I received it. The foot on the jack was bent up in two corners, it was clearly dropped hard at some point. The jack however is still functional, even if I do have to perform minor repairs. I also ordered 2 seals at the same time; the small box the seals came in was bent in half, but I got lucky an the seals were not damaged. 5 stars for the jack, 4 stars for prompt service, -5 stars for packaging.


Welded the new Jacks were I cut the old ones off the cross rod work with the new Jacks everything work out good if you need jacks this is the place to go


Overall great! Paint could be better and stickers made so you can move them


Great product. Exact replacement for the jack on our dump trailer.


I'm been using e-trailer for a few years now. They have a great selection of trailer accessories and parts. There website is easy to navigate and find what you need. I save money and time by ordering with e-trailer.


I've owned many pieces of equipment that require one form of a jack or another. In my experience, Bulldog jacks are the best on the market. Thus, it was a no-brainer to purchase this Bulldog jack as a replacement for the one on my livestock trailer. E-trailer stocked items are always priced competitively compared to other suppliers and the quick customer service is worth the price even if it is a little higher.


Product arrived yesterday. It was not packed very good and the box was torn all to pieces. Not damage to jack except for some scratched up paint. Otherwise the service was great.

Jack is already on trailer and getting ready to install the electric motor.


Product was just as described and is a quality replacement. After shopping around this was the best price I could find. Shipping was quick.


Great service from them just what I needed for my trailer.


Excellent product, I searched locally and on the internet for this product and nobody even came close to etrailer's price. And it shipped the same day! Thanks much!


Worked well and were priced fairly.



Trailer sold, new jacks helped.


Fast shipping works great


Awsome piece, shipped as advertised, fit as advertised, operates as advertised..can't get any better..


Great product and customer service made me aware of free shipping when I purchased enough so I shopped more! Will definitely do alot more business in the future!


Way better than expected shipping way to slow


Excellent prices fast delivery will deal with them again


Works great.


Great product. Have seen lots of them in use.


The price was the best I found and delivery was quick. Thanks

  • Can Drop Leg on Bulldog Square Jack # BD182815 be Replaced
    I reached out to my contact at Bulldog and unfortunately the drop leg for the Square Jack # BD182815 is not available by itself as a replacement part. Your only option at this point is indeed to replace the entire unit with a new assembly. I have attached a short video review on this particular jack that you can check out as well.

  • How to Manually Operate a Bulldog Landing Gear Jack with Powered-Drive Kit # BD1824200100
    What he will need to do is to use an appropriate sized socket and wrench on the end of the rod located above the electric motor on Bulldog Powered-Drive Kit for Single-Speed Jacks, # BD1824200100. He will also most likely need an extension in order to be able to turn the wrench a full 360 degrees and not make contact with the electric motor.

  • Whats the Difference Between Spring Return Jack and a Non-Spring Return Jack
    A spring return in this regard is a mechanism that helps when you are lowering or raising a trailer onto a gooseneck ball. Due to the slow jack speed and the far distance that the foot of a jack has to go when you are raising a trailer there is a pin you can pull in the leg of the jack that will lower the inner section of the jack to take up the majority of the distance that the jack foot has to cover. Well, when it comes time to lower your trailer onto your truck and drive off you will...

  • Recommended Motor Kit for Square Jack on Sundowner 2 Horse Trailer with Living Quarters
    The Sundowner 2 horse trailers with living quarters usually use a weld on square jack like the Bulldog Square Jack - Drop Leg w/ Spring Return - Sidewind - 12-1/2" Lift - 10,000 lbs # BD182815. To add a motor to this style of jack, I recommend the Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity # BD1824200100. This will include the wiring harness, motor, circuit breaker, and rocker switch in weatherproof box. This will allow you to simply connect to a 12V battery....

  • Difference Between Bulldog Square Sidewind 10,000 Lb Weld-On Landing Gear Trailer Jacks
    The Bulldog Square Jack, part # BD182800 and part # BD182815 are very similar but have just a couple of slight differences. They are both 26 inch lift jacks with a 10,000 lb weight capacity, and are sidewind jacks. The # BD182800 has a side-facing plunger pin and has a 27-2/5 inch retracted height. The # BD182815 features a front-facing plunger pin and when retracted has a height of 28-1/2 inches. As you can see there are a couple of differences.

  • Will Bulldog Powered-Drive Kit Work With Bulldog Square Jack
    The Bulldog Powered-Drive Kit, part # BD1824200100, is designed to be able to work with the Bulldog Square Jack, part # BD182815.

  • Is There a Replacement Drop Leg for the Bulldog 12K Jack
    I do have an option for you but we don't have any replacement drop tubes or inner tubes for the Bulldog 12K Jack as they are no replaceable. Therefore, you will need to replace the entire jack which we do have the correct option for, the Bulldog Square Jack part # BD182815 which is rated at 10K lift and 12K support.

  • Can Two Bulldog Square Jacks be Used in Tandem for use on a Trailer
    According to my contact at Bulldog, you can use two of the Bulldog Square Jacks # BD182815 for your trailer. Please make sure that you do mount both of these jacks in the same position and it should work for you. You will need a connecting rod and a crank handle like the Bulldog Replacement Side Wind Jack # BD800090. I have included links to the parts listed above as well as a video for your reference.

  • Would Bulldog Jacks # BD182815 and # BD183816 Work Well on 24k Trailer
    If you ran the Bulldog Jacks part # BD182815 and # BD183816 on a trailer that weighed a max of 24k you'd be good. Each of these jacks has a 10k lifting capacity so you'd have 20k of lifting capacity which is more than enough for the front of a 24k trailer. The jacks are not rated for the total trailer weight and are instead just rated for the amount they can lift vertically.

  • Replacement Jacks and Electric Motor To Upgrade a 1999 Sooner Horse Trailer
    It sounds like the jacks on your 1999 Sooner Horse trailer have been modified since it was new as all the images and videos I can find for your trailer show it using a single jack. Without knowing exactly what jacks you have or the condition it is going to be best to get 2 new Jacks # BD182815. Each jack is rated to lift 10,000lbs which will give you a combined capacity of 20,000lbs. This should be more than enough for your horse trailer since so much of the weight will be on the axles...

  • Availability Of Bulldog 10000lb Trailer Jacks Compatible With Powered-Drive Kit
    The Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity # BD1824200100 you were looking at does use a 1" shaft, but is only a confirmed fit for a Bulldog 12000lb jack so without knowing the brand or model of your current jack I am unable to confirm if it will fit or not. The most surefire option is to go ahead and replace your jacks with the Bulldog Square Jack - Drop Leg w/ Spring Return - Sidewind - 26" Lift - 10,000 lbs # BD182815 which will without a doubt work with...

  • What Follow Leg to Use with the Bulldog 2-Speed Jack Part # BD183903
    The Bulldog 2-Speed Jack part # BD183903 is a lead leg for a landing gear set. If you will be using the jack in tandem then you can use the Bulldog Square Jack part # BD182815 for the follow leg. Only one of the landing gear legs will have a gearbox in this particular application. For the handle you can use the Replacement Bulldog Sidewind Jack Crank Assembly part # BD800090.

  • Powered Drive Kit Availability for a 12k Bulldog Landing Gear Jack
    If you have a single speed, Bulldog jack rated for 12,000 pounds, like # BD182815, you would need the complete powered drive kit, # BD1824200100. If you have a 2-speed jack, the correct powered drive kit is # BD1824180100. The 2 speed motor and single speed motor are not identical so you would need to select the correct one based on your Bulldog jack. There will be some welding required that a qualified welder in your area would have no problem with.

    The Holland Binkley model 48,000 series jacks are very similar to the Bulldog Square Jack - Drop Leg w/ Spring Return # BD182815 which can utilize the Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity # BD1824200100. Your current jacks are not compatible with the kit to my knowledge so you would need to replace the jacks in order to upgrade to the motor kit.

  • Power Drive Jack Recommendation for a 1987 4 Star 6 Horse Slant 13,500 lb GVWR Trailer
    I would recommend going with the Bulldog Square Jack, # BD182815, or the Bulldog Square Jack, # BD182805. These jacks will both work with the Bulldog Powered-Drive Kit, # BD1824200100, that you referenced and feature 10,000 lbs of lift capacity. These are the best heavy duty jacks we carry at this time, and we do not have a hydraulic trailer jack option available.

    The Replacement Bulldog Gear Motor part # BD1046130-00 replaces the powered-drive kit in Bulldog electric single-speed jacks. There are not any powered-drive kits available for the landing gear with the traditional triangular gear box. You would need to upgrade the landing gear to a planetary 2-speed jack part # BD183816 and part # BD182815 with 4 inch tubing. Then add a powered drive kit gear motor part # BD1046130-00.

  • Can I Replace Just One Jack on 2012 PJ Flatbed Trailer With Bulldog 2-Speed Jack, Part # BD183816
    In order for your existing single-speed trailer jack to work with the Bulldog 2-Speed Jack - Drop Leg w/ Spring Return, part # BD183816, it is essential that the existing jack have a cranking ratio (the number of handle turns that moves the jack one inch) that is the same as the 9-turns-per-inch high gear ratio of the Bulldog. If the two jacks do not have the same turns ratio, then the trailer will elevate unevenly, creating a safety hazard. My contact at Bulldog tells me that if the OEM...

  • What Kit to Use for Upgrading Bulldog Square Landing Gear Jacks on Gooseneck Trailer
    Thank you for the photo of the landing gear on your gooseneck trailer! From what I can see it looks like you have the Bulldog Square Jack # BD182815 installed on both sides. If this is the case then you'll need the Bulldog Powered-Drive Kit # BD1824200100 to upgrade them to electronically controlled instead of manually controlled. You'll want to verify this is the gooseneck landing gear kit you have prior to purchasing though.
