S&S Cycle 70-84 BT 4-1/2in Stroke Flywheel Assembly

What you get here is a complete 4-1/2 inch stroke flywheel assembly, ready to go into your custom Big Twin motorcycle. This assembly is designed to replace the original flywheels in S&S 93-inch P93, P93H, SH93, and SH93H engines. It's built for custom bikes using the 1970 through 1999 style chassis and drivetrain, specifically for engines with alternator/generator or alternator style crankcases.

These flywheels are CNC machined from heat-treated, closed die steel forgings. That means they're stronger than the cast iron flywheels you might find elsewhere, and even stronger than later style steel flywheels. They come dynamically balanced and fully assembled with S&S Cycle's own mainshafts and heavy-duty 7.440 inch connecting rods, so you know it's built to handle the power.

This is a solid option if you're building a custom Big Twin and need a reliable, strong foundation for your engine's rotating assembly. It's designed to be a direct replacement for the specified S&S engines, making installation straightforward as long as you're familiar with Big Twin engine work.
