Hey Tim, thanks for reaching out. We used to carry the Replacement Gear Kit for Bulldog Sidewind Jacks # BD500212 but we don't offer it anymore. Unfortunately, Bulldogs parent company went belly-up and they stopped producing and shipping product. So at this point, if the gears in your jack are damaged and in need of replacement, the only option will be to get a whole new jack.
The etrailer Square Sidewind Trailer Jack # TJDDP-20000SP-F is a suitable replacement for the Bulldog 12K jacks.
