About This Product
This Diamond primary chain is a 76-link endless replacement designed for heavy-duty use in Big Twin primary drives. It fits 1979 to 2006 FLT and Touring models, as well as 1982 to 1994 FXR models. Replacing OEM 40037-79 and 40037-79A, this chain is manufactured to provide long-lasting performance and minimal stretch. An endless chain design is preferred for primary applications to ensure maximum reliability under the high torque loads of a Big Twin engine. Whether you're doing a routine service or a full engine build, installing a fresh Diamond chain is a smart move to keep your drivetrain running smoothly for years to come.
Manufacturer part number: 505955.
