  • Dual Jack Landing Gear for Gooseneck Trailer Transporting Large Water Tank
  • The weight of 1600 gallons of water, without the water tank's own weight factored in, is about 13,350-lbs. For such a high-weight application I suggest Bulldog Square Jacks # BD182804 and # BD182805 along with Connecting Rod # BDCS730300. Two jacks are definitely the way to go. If you wish to motorize this jack setup you can also add motor kit # BD1824200100. I also recommend you first determine the actual pin weight of the loaded trailer so that you can be sure to select jacks with...

  • Availability of Cross Shaft for Use with Bulldog Jack BD182804
  • We have the fixed cross shaft extension tube part # BDCS730300 which could be used to extend out the crank of the Bulldog Jack part # BD182804 that you referenced. This shaft is 72-3/4 inches long though which might be too long depending on the width of your trailer.

  • Recommended Double Trailer Jack/Landing Gear For 20 Foot Tandem Axle Log Trailer
  • For your 20 Foot double axle log trailer with 14K GVWR, I recommend the Bulldog 2-Speed Tandem Landing Gear Set - Weld On - 17" Lift - 45,000 lbs # BD500153. This system is rated higher than you requested but still falls within your budget. This is an extremely hard working landing gear set for your application. It has two cranking gears and a traditional gearbox with sidewind crank. With this system you will need the Fixed Cross Shaft Extension Tube for Bulldog Tandem Landing Gear...

  • Shaft Diameter for Bulldog Powered Drive Kit for Single Speed Jacks BD1824200100
  • The Bulldog Powered Drive Kit for Single Speed Jacks # BD1824200100 has a 1-inch diameter shaft to transmit its power to your landing gear. The motor alone from this kit is available as part # BD1046130-00. A 1-inch cross shaft # BDCS730300 is also available.

  • Replacing Landing Gear on 2013 Jayco Seismic 3914 Toy Hauler
  • 8,000 lb jacks are going to be the highest rated landing gear sets we offer that will bolt right up to your trailer without modification. For that we have the Bulldog part # BD500162 which would work well. If what you really want something high capacity that would make easy work of your trailer the Bulldog Set part # BD500153 has a capacity of 45,000 lbs. You would need the extension tube part # BDCS730300 as well. You will need to modify the mounting brackets on your trailer to fit...

  • Recommended Landing Gear For 2004 CM Stock Livestock Trailer
  • I spoke with my contact at Ultra-Fab about the Power Twin II Electric Stabilizer, part # UF39-941705. They recommend not using this system because of the movement any livestock would make in the trailer. They said any movement would cause additional stress on the system and they would not recommend it. This system is not designed to lift, as it is made to stabilize a steady load only. I recommend installing a tandem landing gear set like part # BD500154. This certainly has the capacity...

  • Recommended 2-Speed Jack for a 34 Foot Gooseneck Flat Bed Trailer
  • I have a couple options for you but there isn't a electric kit for a 2-speed jack that we currently offer. The Bulldog powered-drive kit # BD1824200100 for a single speed jack is a solid option. To use this setup, you will need 2 single speed jacks like # BD1823050383 and the Bulldog powered-drive kit # BD1824200100 and the cross shaft # BDCS730300. You may also need the hand crank # BD8001090283. For a 2-speed setup, I recommend using the 2-speed tandem landing gear set # BD500153 and...

  • Recommended Bulldog Electric Lift For 2014 Featherlite LQ Horse Trailer
  • If you have a two leg manual lift like the Bulldog Square Jack # BD182400, then you simply can add the Bulldog Powered-Drive Kit for Single-Speed Jacks w/ 12,000-lb Capacity # BD1824200100 to give you the electric lift. You will simply add the Fixed Cross Shaft Extension Tube for Bulldog Tandem Landing Gear - 72-3/4" Long # BDCS730300 for that application. You can alternatively use the Bulldog Velocity Series Electric Landing Gear Jack - 24" Lift - 12,000 lbs # BD185400 if you prefer....

  • Recommended Gooseneck Trailer Powered Landing Gear for Completely Weather Exposed System on Trailer
  • When landing gear like # LG-1 is used on exposed trailers the electric component needs to be covered. Most of the time this is done with a custom sheet metal box as it doesn't take much just to shield the motor from the elements. The legs are powder coated and the gear box is aluminum, so you won't have issues with them being exposed, but the motor is another story. Your other option is to use a jack like the Bulldog Velocity Series Electric Landing Gear Jack # BD185400 or for a...

  • Can Two of the Bulldog Square Jacks Part # BD182805 Be Used in Tandem
  • In order to use two of the Bulldog Square Jack part # BD182805 in tandem you will need to take out the vertical pinion bevel gear in the passenger's side jack and rotate that 180 degrees. This will allow you to use two of these jacks in tandem on a trailer. I have attached a review video that shows how to replace the gears for you which you could then use to help you rotate the pinion bevel. If you do not already have the handle for this jack then you can use part # BD015181. You will...

  • Can a Powered Drive Kit be Added to a Trailers Landing Gear
  • The Bulldog Powered-Drive Kit # BD1824200100 that you referenced is designed to fit Bulldog single speed landing gear jacks with a 12k capacity. If that is what you have on your trailer this would work well for you. There isn't a universal motor kit that will work with most landing gear sets. You will need to determine who made the jacks of your trailer so that you can see if there is a powered drive kit available for it. Otherwise you will need to upgrade your jacks to a Bulldog...

The dual speed jack with gear box weighs 81 lbs. The hand crank weighs 4 lbs.
