Swap your Gen III Hemi’s factory cam for a COMP Cams HRT Camshaft and you’ll boost horsepower without beating up your valvetrain. The hydraulic roller cams have COMP’s Low Shock Technology profiles designed to maximize horsepower, improve stability at higher RPM, and are gentle on the valve springs for longer life.
