S&S CYCLE Flywheel Assembly 320-0601

A quality flywheel assembly is fundamental to engine reliability and performance—especially in high-output Harley-Davidson applications where stock components often become the weak link. The S&S Cycle 320-0601 is engineered with forged steel construction and a robust tapered sprocket shaft designed to handle both stock and heavily modified engines without compromising durability. If you're building a custom motor or refreshing a tired engine, this complete assembly eliminates the guesswork and ensures your crankshaft can handle the demands you're about to place on it.
