Hey Jess, thanks for reaching out! Sadly, we don't have the Replacement Gear Kit for the Bulldog Sidewind Jacks, part BD500212, available anymore. Bulldog's parent company closed down, and the Bulldog products are no longer being made or shipped. So if the gears in your jack have failed, replacing the complete jack is going to be the way to go rather than trying to find the gear kit.

For a replacement, I'd take a look at the etrailer Square Sidewind Trailer Jack, part # TJDDP-20000SP-F. It's a 12K jack and would be a good replacement option for the Bulldog 12K jacks.

Which Bulldog jack are you working on?
