Do you have a question about this Trailer Jack?

  • Recommend Electric Landing Gear For 26 Foot Gooseneck Trailer
  • Yes, checkout the Ultra-Fab Deluxe Electric Landing Gear Set, part # UF17-943010. This electric landing gear set will bolt to the frame of your gooseneck trailer. The combined weight capacity of the # UF17-943010, is 12,000 lbs. For a non-electric landing gear set, we have the Bulldog 2-Speed Tandem Landing Gear Set, part # BD500153. The Bulldog landing gear is a weld-on application, and you will also need to have a connecting rod fabricated to connect both jacks. I would recommend having...

  • Bolt On Trailer Landing Gear Jack for a 24,000 Pound Trailer
  • Bulldog jack # BD500154 is very much overkill for a 12 ton trailer but also one of only a few we are going to have for 24,000 pounds. The manufacturer has not provided us with images and we have not yet had the item in to take pictures. But it is a landing gear set not unlike # BD500153 which is the weld-on counter part. We also have a 45K option, # BD1839060383, bolt on or # BD1839050383 weld-on. For 25K we have some options that I have linked for you but they are all weld on.

  • 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...

  • Replacement Bulldog Tandem 2-Speed Jack Recommendations
  • The only tandem Bulldog Jack set with 2 speeds that we offer is the Bulldog 2-Speed Tandem Landing Gear Set # BD500153. Which if you needed them individually you would want the part # BD1823050383 and part # BD1839050383. This jack set has a 45,000 lb capacity and does not have a spring release handle like you said you have though which makes me think you may have something different like the part # BD182800 that you referenced which is actually a single speed jack.
