Ask the Experts about this Bulldog Trailer Jack
Do you have a question about this Trailer Jack?

  • 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.

  • Are Side-Frame Mount Jacks Available With Different Gear Ratios
  • There are jacks with different gear ratios but the only one in the 12,000 lb range is the Bulldog 2-Speed Square Jack - Drop Leg w/ Spring Return - 12-1/2" Lift - 12,500 lbs # BD183750. That lift may not be enough so another option if you need more lift is the Bulldog 2-Speed Jack - Fixed Leg - Traditional - Weld On - 17" Lift - 22,500 lbs # BD1839050383. Apart from that you may want to check out an electric jack set like the Ultra-Fab Deluxe Electric Landing Gear Set # UF17-943010...

  • 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. If you need a...

  • Recommended Bulldog Square Sidewind Jack with Powered Drive
  • The Bulldog Powered-Drive Kit # BD1824200100 referenced in your question can be used on the Bulldog Square Jack # BD1823050383, however it will reduce its capacity to 12,000 pounds so it may not be a good option. If you are needing a sidewind trailer jack with the 22,500 pound capacity that the Bulldog Square Jack # BD1823050383 provides, I recommend simply sticking with the base unit and using it as a standard manual jack. You can add the Sidewind Crank # BD8001090283 for easy operation. I...
