7816-1 Acorn motor sprocket nut

The motor sprocket nut is a critical fastener in your Harley's drivetrain, and this Colony version adds a bit of style to a normally utilitarian part. This acorn-style nut is finished in brilliant chrome and features a 7/8-14 thread pitch. It is designed to fit a wide range of Big Twin models from 1955 all the way through 2006, with the exception of 2006 Dyna models. Using an acorn nut here provides a finished, custom look inside the primary. Colony’s hardware is known for its precise machining, ensuring a secure fit on the crankshaft to keep your compensator or motor sprocket locked down tight while looking great behind the inspection cover.
