Description
If you’re building a high-performance engine or replacing a worn crankcase on a Harley-Davidson big twin, the S&S CYCLE Crankcase gives you the strength and precision you need without compromising the classic look of your machine. Built from 356-T6 aircraft-grade aluminum with reinforced wall sections, this crankcase handles aggressive cam profiles and extended strokes while resisting the punishment of forced induction and high-RPM applications. Whether you’re a professional racer or a dedicated builder, this is the foundation that won’t let you down.
