This 4-3/8" stroke 8-1/2" diameter flywheel assembly replaces the original flywheels 2007-'16 HD® big twin engines, when using high performance pistons that allow the use of connecting rods with full width wristpin ends. Sprocket shaft has the bearing race pressed on and is compatible with stock roller style sprocket shaft bearing.
- Assembly is trued to less than .0005" runout on pinion and sprocket shaft bearing surfaces, making them capable of higher rpm and fully compatible with gear drive cams
- 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 full width 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
