S&S Cycle 2007+ BT 7.575in Rod 4-5/8in Stroke Flywheel Assembly

If you're rebuilding the engine in your 2007 or later Harley-Davidson Big Twin, or a 2006 Dyna model, and you're looking for a solid foundation for your build, this S&S Cycle flywheel assembly is a strong contender. This assembly is designed to replace the stock unit, providing a reliable core for your engine's rotating assembly. It's specifically built for non-balanced engines and serves as a direct replacement part for S&S 120R and 120ST crate engines, ensuring a proper fit and function for those high-performance applications.

This flywheel assembly features a 4-5/8 inch stroke and uses a 7.575 inch connecting rod. The precision balancing and well-built construction are crucial for smooth operation and longevity, especially when you're pushing your engine beyond stock performance levels. Building an engine from the crank up requires attention to detail, and starting with a quality flywheel assembly like this one sets the stage for a reliable and powerful powerplant. Remember that this assembly does not include the sprocket shaft bearing race, so you'll need to source that separately if your project requires it.

When undertaking a significant engine build, especially one that involves replacing core components like the flywheel assembly, it's always a good idea to consult your service manual for specific installation procedures and torque specifications. This ensures that everything is assembled correctly for optimal performance and durability. Please note that this part is not CARB approved and cannot be shipped to California.
