Hello TJ,

Thanks for writing in, I am glad you found us.

The Bulldog BD182513 has been discontinued, but the etrailer Square Jack # TJD-12000SP-R2NH is the closest replacement we offer.

The original Bulldog jack featured a 10,000 lb lift capacity, 12,000 lb static capacity, a 4" square outer tube, weld-on installation, sidewind operation, a 26-3/4" retracted height, a 39-1/2" extended height, and 12-3/4" of lift. It was also a fixed-leg design with no drop leg.

The etrailer # TJD-12000SP-R2NH matches the Bulldog's 10,000 lb lift capacity, 12,000 lb support capacity, 4" square tube construction, and weld-on design. The primary difference is that the etrailer jack uses a spring-return side-pin drop leg instead of a fixed leg. This gives it 25-3/4" of total travel and reduces the amount of cranking required when hooking up and unhitching.

As long as you have enough clearance beneath the trailer for the drop leg assembly, the # TJD-12000SP-R2NH is an excellent replacement for the discontinued Bulldog # BD182513 and provides the same lifting and support capabilities.

I attached a review for you to check out where a customer got a set of the # TJD-12000SP-R2NH to fix his landing gear. I also attached an image of the specs from the old Bulldog page since you can no longer see it.

What kind of trailer is this going on?

When we cannot get the same jack we often look to replace both jacks, so the gears sync better. Not saying you have to just seems smoother raising and lowering.
