Do you have a question about this Trailer Jack?

  • Replacement Parts For 12,000 lb Jack
  • We don't have any Trailer Tough brand jacks, however, the Replacement Screw and Nut Kit for 12000-lb Capacity Bulldog Jacks, # BD500217 may work. If you trade out the gears # BD500212 and bearing # BD001015, you will basically have a new jack on the inside. You could also just replace the entire jack with the Bulldog Side Wind Jack Assembly - 12,000 lbs # BD182513, however this jack does not have a drop leg. If you want the hand crank you will need # BD015181.

  • Availability of Trailer Jack with Over 20k Capacity and Can Be Set at 31 inches of Height

  • Replacement Trailer Jack For Rice Trailer That Currently Has Ram 14K Jacks
  • The Ram 14K jacks don't have a replacement rod and nut available like the 12K # TJD-12000-RODNUT and are no longer available in that capacity. I recommend changing out your jacks for the 12K option. You can use the Bulldog Side Wind Jack Assembly - 12,000 lbs # BD182513 or the Buyers Products # 3370091410H or # 3370091415H as a replacement. These are all excellent products for the price to help your trailer function as intended.

  • Landing Gear Jacks for a Keystone Cougar 5th Wheel Trailer
  • Bulldog square weld-on jack # BD182513 could potentially be used on a 5th wheel trailer but it really is meant for trailers with exposed frames and doesn't have stops on the outer tube for brackets like landing gear jacks have. If you have brackets already then you would just need to weld on some stops to the outer tube and the heights needed. For a tandem, manual landing gear set you could use # RVLG-8HDL which is both legs with the stops already on them, brackets, handle, and connecting...

  • Replacement Side Cranking 12K Bulldog Square Trailer Jack Leg
  • A drop leg on a jack will just be held to the inner leg with a pin such as # BD70129201. It sounds like the inner leg on your jack is damaged. That part is not available but you can replace the hole leg. We have 1 Bulldog square, side crank jack rated for 12,000 pounds and it is # BD182513.

  • Side Mounted, Square Sidewinding Trailer Jack with 18 Inches of Travel
  • For square, sidewinding jacks with a drop leg I can get you close to 18 inches of lift. You could potentially use Bulldog jack # BD1823050383 with 17 inches of lift. If you want to go above that though you would need a jack with a drop leg such as # BD182701 which has a total of 26 inches of lift. I have linked videos of both of these jacks for you.
