We specialize in producing custom sprockets for specific applications, i.e. a custom build or reproducing units that are simply not available anymore or not available in tooth counts other than stock.

Our units made from high quality 8085 Steel or 7057-T6 billet aluminum that can be hard anodized. Our steel units are clear coated.

Our Custom Sprockets are a unique pattern to 7th Gear, you won't find another like ours! Our sprockets can be made for most any application and in any tooth/chain combination desired, however if you have something unique in mind for a custom unit, let us know and we can take your idea and turn it into metal!
