Description
The S&S Cycle Motor Sprocket Shaft Assembly is engineered for Big Twin engines that demand reliable power transfer and precise timing control. This domestically manufactured component ensures consistent performance whether you’re running a stock configuration or a modified engine, eliminating the guesswork of sourcing individual shaft, nut, and key components separately. Upgrading to a purpose-built sprocket shaft assembly eliminates potential fitment issues and delivers the durability required for sustained high-RPM operation.
