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. You feel harder acceleration off the line, and more mid-range and high RPM horsepower. And because these high-lift cams are engineered with Harley-Davidson's cam dynamics testing, you maintain quiet operation and have seamless integration with the engine's valve train components. To accommodate the extended lift, Performance Valve Springs (P/N 18100080) must be installed.
Replacement cams for '17-later Touring models equipped with Screamin' Eagle Milwaukee-Eight Stage IV Kits. Installation requires the use of Performance Valve Springs P/N 18100080 and Cam Drive Retention Kit P/N 25566-06. Installation may require Cam Spacer Kit P/N 25928-06. All models require ECM calibration with Screamin' Eagle Pro Street Tuner for proper installation. See Dealer for details.
