Product Details
This flywheel assembly includes the S&S Cycle 5-inch stroke flywheels, balanced for S&S SH103 engines with 3-5/8 inch bore pistons. These are designed to replace the original flywheels in 1970 through 1984 Harley-Davidson Big Twin models that are equipped with an S&S SH103 engine.
You're getting a well-built assembly here. The flywheels are CNC machined from heat-treated, closed-die steel forgings, which makes them stronger than cast iron or even later-style steel flywheels. They come fully assembled and dynamically balanced with premium S&S mainshafts and heavy-duty 7.440-inch connecting rods, ensuring smooth operation and durability for your engine build.
This assembly is a direct replacement for the stock flywheels in the specified S&S SH103 engines. Please note that this part is not CARB approved and cannot be shipped to California. Always refer to the manufacturer's installation instructions for proper assembly and tuning procedures.
