S&S Cycle 95-98 EFI BT 4-1/4in Stroke Flywheel Assembly

This flywheel assembly from S&S Cycle gives you a 4-1/4 inch stroke and an 8-1/2 inch diameter, designed to replace the original flywheels in your 1995 through 1998 EFI big twin engines. The left flywheel has timing notches machined into its rim, which will work with your stock crankshaft position sensor for accurate engine timing.

You're getting a well-built assembly here. The flywheels themselves are CNC machined from heat-treated, closed die steel forgings, making them stronger than cast iron or even later style steel flywheels. They're also dynamically balanced and come fully assembled with S&S Cycle's own premium mainshafts and heavy-duty 7.440 inch connecting rods. This means you're getting a solid, balanced rotating assembly ready to go.

When you're looking to rebuild or upgrade the bottom end of your big twin, this assembly is a strong option. It's built to handle the demands of these engines and provides a significant stroke increase over stock, which can lead to improved torque and power when paired with the right components.
