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 does not have the stock style bearing race pressed on. This flywheel assembly is for crankcases with a Timken® sprocket shaft bearing.
Flywheel assembly is three piece design. Pinion and sprocket shafts are forged as part of the flywheel. The only joints in the assembly are where the 1.671" diameter connecting rod crankpin is pressed into the flywheels. Flywheels are CNC machined from heat-treated, closed die, steel forgings, which are 114% 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. 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.

If you want the best go with S&S!
Had a major malfunction with a S/E forged flywheel. I should've purchased the S&S setup to begin with & I wouldn't be back in the this position. This item is strong & stout as well as sexy! I could not be more satisfied.
