Fast shipping and good communications. etrailer has constantly delivered with all parts ordered and the one and only time there was damage to an item ordered, they sent me a new one next day. Awesome outfit to deal with.
by: Glyn H.03/08/2018
These parts were a great time and money saver. The tongue jack on this trailer was welded to the trailer cross member by the trailer manufacture, so removing the old jack and welding on a new one was going to be expensive and time consuming; plus the trailer would be out of service for a couple of weeks. With the parts to rebuild the jack, we did the repair in less than two hours. As a bonus, the parts actually arrived two days sooner than promised. Thank you etrailer.com for the great service.

Parts came in a timely manner and were just what we needed. One year later and still going strong

Went to drop my gooseneck horse trailer after use and no-go! Apparently the screw jack became stripped over the years and needed to be replaced. The hardest thing about this project was removing the entire unit from beneath as shown in the pictures. For clearance I had to not only drive the rear wheels onto small ramps but also dig beneath the jack to drop everything out. Everything fit perfectly. The video was great at explaining things. Brendan gave me a few shipping options and items arrived promptly without breaking the bank.

Just what we needed! Worked perfectly.
Thank you etrailer!
by: Wesley 06/01/2020
Exact fit parts. Instructions were helpful as were the available videos. Works much better and easier now. The original bulldog hitch worked for almost 20 years.
by: William02/25/2023
It all was great but the shipping took forever, my fault I chose basic but damn that took long!! I just order the rod bc that ended up being the real problem and used priority shipping and you tell me how long it will take?
by: Scott04/17/2020
Did not know the make of the landing gear as all tags were removed when builder painted trailer. James with etrailer was very helpful in figuring out what was needed and the parts are are a perfect replacement for the damaged parts. Parts look to be well made and should last for many years. Thanks James and etrailer for the help.
by: Ken07/17/2018
Product was delivered quickly and was exactly what we were after. Turns out the kit covered several different versions of the jack assembly, but only minor modification (drilling out the pin hole in the cross shaft) was required for the included parts to drop into place. Great service, great product!!

recieved product in short amount of time and correct. excellent service

I had questions if my old jack could be converted to electric and Conner answered
Immediately with how and the part number needed, these folks are spot on.

Website was great. Easy to use and full of useful information. Processing was quick and order arrived promptly. I was kept informed all the way through. Will definitely reuse and recommend.
by: Michael01/22/2020
Great products. Other than a hard time driving out the old pin from sprocket, all parts assembled daily. Better than cutting of old assembly and welding new one one.

- Trying to Get Inner Drop Leg of Bulldog Jack to Move After Getting Stuck All the Way DownSounds like it's binding up in some way. I would try jacking the trailer up and see if that puts enough force on the drop leg that it frees itself up and allows the pin to drop into a hole again.
view full answer... - How to Install the Replacement Gear Kit for Bulldog Sidewind Jacks Part # BD500212In order to remove the .25" diameter pin that is included with the Replacement Gear Kit for Bulldog Sidewind Jacks part # BD500212 you will need to push the spring back to one side with a flathead screwdriver and the pin should fall right out. If it does not you may need to take a hole punch and tap it out. I have attached an install video of this process for you as well. Skip to 1:30 to see the .25" diameter pin removed.
view full answer... - Does Replacement Gear Kit BD500212 Fit 3-Car Trailer JackThe Bulldog Replacement Gear Kit # BD500212 will not fit a 3-car trailer jack; this kit is only a direct replacement for Bulldog sidewind jacks with a 12,000 lb capacity. I have added a link below to our entire selection of replacement gears for trailer jacks, though you will need to know the model and capacity of your jack to ensure you get the right replacement.

- Gear Set and Replacement Spring for Bulldog 180 Series Sidewind JackHey Tyson, it looks like the kit you are needing is the part # BD500212 which is a gear set for your Bulldog 180 series jack that comes with the spring as well.
view full answer... - Replacement Gear Kit for Bulldog 12,000 lb Capacity Sidewind JackWe do have the inner workings of a Bulldog 12,000 lb capacity sidewind jack, if you were referring to the gears. If you have a sidewind jack, the correct replacement part is the Replacement Gear Kit for Bulldog Sidewind Jacks with 12,000 lb Capacity # BD500212.
view full answer... - Replacement Repair Parts for 5th Wheel Landing Gear & Replacement Landing Gear SetsSince trailer makers don't maintain spec on the jacks they install (especially for a 5th wheel that is close to 17 years old) you'll want to check the jack for any part numbers to help you choose the correct repair kit. We do have bevel gear repair kits for jacks and landing gear from most major makers including Atwood, Stromberg Carlson, Fulton and others. In some cases repair kits for one brand will work fine for another since many of these products do share a common manufacturing origin,...
view full answer... - Heavy-Duty 12000 lb Bulldog Jack Replacement Cross Shaft and Bushings RecommendationI have an option for you, but I spoke to my contact at Bulldog to try and get a replacement cross shaft for you and he said they are not available. He said that you will just need to get a 12 inch long section of 1 inch cold rolled steel and then drill a .4 of an inch on either end of the rod 1-1/4 from the ends and then a 1/4 inch hole near the middle of the shaft but not completely centered. To get an idea what I am talking about check out the picture I attached. The Replacement Bulldog...

- Replacement Spring for Bulldog Sidewind Jack with 12000-lbs CapacityI have a solution for you, but in order to replace the spring component on your Bulldog jack you would need to purchase the entire Replacement Gear Kit for Bulldog Sidewind Jacks w/ 12,000-lb Capacity # BD500212. This would be the only way to get the appropriate spring for this jack. Parts like this do malfunction occasionally, so it might be worth having the extra parts on hand in the event that the gears stripped out at some point in the future. You could also completely change all...
view full answer... - Can Replacement Gear Kit for Bulldog Sidewind Jacks Retrofit Old Bulldog JackThe # BD500212 is only designed as a replacement kit. It may be possible to retrofit but we have never tested it. Bulldog may have more information on this but I'm guessing they will say to completely replace the jack. The BD500217 is on extended backorder so I don't know when we will get it back. You may be able to find it elsewhere to attempt a repair.
view full answer... - Recommended Rebuild Gear Kit for Bulldog JackWithout the spring that holds the shaft pin and gear in place, you likely will need to drive that pin out as it is likely pressed in. If it is really stuck in there, you may need to drill it out to ensure you don't damage the jack. Then you can use the Replacement Gear Kit for Bulldog Sidewind Jacks w/ 12,000-lb Capacity # BD500212.
view full answer... - Replacement Gears for Bulldog Sidewind Jack BD182701We do carry the gears for your Bulldog Jack BD182701; you need the Replacement Gear Kit for Bulldog # BD500212.
view full answer... - Recommended Replacement Gears for a 015796 Hammerblow 180 Series Jack It's most likely not that spring and instead a gear issue. The fact that it is slipping or starting to means the teeth on the gears have been worn down. The grinding feeling means it's getting worse. Like you said the trailer's getting up there in years. The 015796 Hammerblow 180 series have been discontinued for quite awhile but we do offer the Replacement Gear Kit for Bulldog Sidewind Jacks item # BD500212.
view full answer... - Replacement Gears for Bulldog 10K Square Jack 182417Thanks for reaching out! To replace the inner gears of your Bulldog square jack you need the Bulldog Replacement Gear Kit # BD500212 which I confirmed with my contact at Bulldog will work for your 182417 jack. I've attached a few videos for you to check out as well.

The larger of the two gears has an OD of 3.42 inches and an ID of .875. The smaller gear has an OD of 2.50 inches and an ID of 1 inch.

- What is the Purpose of the Spring Inside of a Bulldog 12K Square JackThe spring that comes with gear set # BD500212 for Bulldog 12K jacks is a compression spring. It keeps tension on the upper gear to help keep in place and aligned. I have included a picture that shows where the inner pieces go inside the jack.

- Correct Replacement Motor for a Bulldog 12K JackIt sounds like either the motor is shot or the gears are worn. You're going to want to test the voltage of the motor first before deciding to replace it. If your motor is not getting enough voltage then you're just going to need to replace it with the Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity # BD1824200100. This kit is going to include the powered-drive assembly, the torque stop tube with energy absorber, a terminal box, a wiring harness and switch box, a...

- Troubleshooting A Roll Pin That Won't Slip Into Place In A Bulldog 10K Square Jack If you have the correct pin in place for your Bulldog Square Jack # BD182500 and it's sticking out that far then you would want to push it into the slot more to secure the gear in place. Cutting it off will most likely lead to it eventually failing and your gear working itself out of place. I'm assuming this is probably going to be challenging to do but you can try rotating it to have the pin facing up so you can try to push it in further or you could leave it how it is in the picture and...

- Is Gear Kit Needed to Install Bulldog Powered-Drive Kit for 12,000 Pound Trailer JacksThe Replacement Gear Kit # BD500212 is only needed with the Powered-Drive Kit # BD1824200100 if the jack was manufactured before 2006.
view full answer... - Replacement Screw for Bulldog 12K Jack with 1 Inch Diameter RodIt doesn't sound like you have a 12K Bulldog Trailer Jack as they all used a 1-1/4" diameter threaded rod both pre-2003 and post-2003. Please keep in mind that the rod is measured by the threaded portion. If you can confirm the threaded rod is measured correctly then you would need to look for other identifying marks on the jack. If none are present then the only option I have for you is a full replacement like the Bulldog Square Jack part # BD182701 which has a 12,500 lb capacity and offers...
view full answer... - How to Install the Replacement Gear Kit # BD500212There is an initial pin that holds the shaft at the top of the jack into place. You will simply need to use a flat head screwdriver to compress the spring that is covering up that pin and the pin should fall right out. From there it is just a matter of pulling the internal gears and equipment out so that you can replace it with the Replacement Gear Kit # BD500212. I have attached a video of this process being done that you can use as a reference. This will then enable you to install the...
view full answer... - Gear, Bushing, & Spring Replacement Kit For Jacks Manufactured Before 2003On the Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity # BD1824200100, if your jack was manufactured before 2003, you will need the replacement gear kit for sidewind jacks # BD500212 to complete installation of this drive kit. This maybe the missing piece that will make it work together. This is a gear, bushing, and spring replacement kit. If you have any further issues, I will be happy to help.
view full answer... - Are the Spring Returns of Bulldog Jacks Repairable if the Spring Return Function Stops WorkingIt sounds like you have a spring return Bulldog landing gear jack that has a broken spring and now won't retract when you activate the release lever. I spoke to my contact at Bulldog and he said the springs aren't repairable so you would need to replace the jack with something like the part # BD182701.
view full answer... - Are There Replacement Parts for my Frozen 12,000 lb Gooseneck Bulldog JackThe gooseneck trailer jacks are repairable. It is hard to say exactly what is wrong with your jack and how difficult it would be to repair, but we sell replacement parts that could fix your jack. We sell a Replacement Screw and Nut Kit, part # BD500217, as well as the Replacement Bulldog Sidewind Gear, part # BD500212, that you referenced. I would recommend that you take yours off and take it apart carefully and see if you can find what is causing the jack to be frozen and then replace...
