Screamin' Eagle SE8-515 Cam - Milwaukee-Eight Engine

Part Number 25400201




The SE8-515 Cam is designed in conjunction with the system-matched components contained in the Screamin’ Eagle® Stage IV Kit. The cam’s high lift and long duration profile is ideal for opening the valves to efficiently fill the combustion chamber of larger displacement engines.

  • Adding fuel/air volume in the cylinder yields a more powerful combustion event and results in more power and significantly more torque delivered to the rear wheel
  • Feel harder acceleration off the line and more mid-range and high RPM horsepower
  • High-lift cams are engineered with Harley-Davidson®’s cam dynamics testing
  • Maintain quiet operation and have seamless integration with the engine’s valvetrain components
  • To accommodate the extended lift, Performance Valve Springs (P/N 18100080) must be installed

Can you add this cam to the Stage III kit?

Will it add performance over the 498 cam?
Asked by: Damzhd
I have the stage 4 kit fitted to my Road King M8 2017, and it still gets beaten by standard 114 CVO Street Glides .... why is this ?? ... the dealer said its because the CVO 114 has a longer stroke crank ... I thinks its because the stage 4 kit isn't what its made out to be ....
