# S&S Cycle 2007+ BT 4-3/8in Stroke Flywheel Assembly w/o Sprocket Shaft Bearing Race

This 4-3/8" stroke 8-1/2" diameter flywheel assembly replaces the original flywheels 2007-'16 HD® big twin engines, when using stock pistons.

-   Flywheels are CNC machined from heat-treated, closed die, steel forgings, which are 114 percent stronger than late style stock steel flywheels
-   Fully assembled with premium quaility S&S® heavy duty 7.659" connecting rods, with tapered wrist pin ends, and dynamically balanced
-   The only joints in the assembly are where the 1.671" diameter connecting rod crankpin is pressed into the flywheels
-   Pinion and sprocket shafts are forged as part of the flywheel
-   Flywheel assembly is three piece design
