Hello John,

Thanks for writing in!

Based on your question, I have a feeling we aren't the first place you've checked. Unfortunately, we are out of stock on the Replacement Jack Screw and Nut Kit # BD500217, and I don't as of now, we don't know if they will ever be back since First Brands claimed bankruptcy and Bulldog was part of First Brands.

If you're not able to find the rebuild kit, replacing the jack may be your best option. The etrailer Square Jack with Handle # TJDDP-20000SP-F is a 12,000 lb capacity jack that could work as a replacement. Before ordering, you'll want to compare the mounting style, the outer tube dimensions, the lift capacity, and the amount of travel on your current Bulldog jack to make sure it's a suitable replacement. If those match up, the etrailer jack is a great option.

Please feel free to send me your exact model number so I can make sure that replacement will work.

What kind of trailer is this on?
