S&S 4-5/8" Stroke Flywheel For Harley Twin Cam

The flywheels are the heart of any performance engine and S&S Cycle has been perfecting the art for over six decades. Stronger, more durable, and trued to a spec others can only dream of.

  • Heavy duty connecting rods
  • 8-1/2" diameter flywheel
  • Pinion and sprocket shafts are forged as part of the flywheel
  • CNC machined from heat-treated, closed die, steel forgings, which are 114% stronger than late style stock steel flywheels

  • Capable of higher rpm
  • Fully compatible with gear drive cams
