9716-8 Cyl base lockwashers

These 7/16-inch cylinder base lockwashers from Colony are essential for keeping your top end secured properly. Finished in a traditional black parkerized coating, they offer an authentic look for vintage restorations. They are designed to fit 1930 to 1978 Overhead Valve and Sidevalve Big Twin models, as well as 1957 to 1986 Sportsters. When you are rebuilding an old motor, using the right hardware matters, and these are a direct replacement for OEM 7055. This pack includes eight lockwashers, providing enough for a complete cylinder base installation on most applications. They provide the necessary tension to prevent nuts from backing off under the heat and vibration of a running V-twin.
