For the rider demanding no-compromise performance. With the largest displacement and the most power of any Harley-Davidson Screamin’ Eagle Stage Kits, this Harley-Davidson Screamin’ Eagle 121ci to 135ci Stage IV Kit was engineered by the pros at Harley-Davidson to deliver instant arm-stretching torque through the entire rpm range. Made for riders seeking maximum displacement, compression, and flow, it delivers 144 horsepower and 149 ft-lb of torque to the rear wheel!
This Stage IV Kit features the finest Screamin’ Eagle components. Many of these new components were informed by extensive testing by the Harley-Davidson King of the Baggers Factory Racing Team.
The Stage IV kit consists of: All-new Screamin' Eagle® Extreme CNC-ported cylinder heads, 68mm throttle body and new cast 68mm intake manifold, new SE8-550 high-lift cam and 6.8 g/sec fuel injectors work together to feed the engine large volumes of air and fuel to help maximize power. New forged high-compression pistons and rings are designed to withstand increased combustion forces. Also includes high-performance tappets, new patent-protected 4.31" steel sleeve cylinders, and Screamin' Eagle® Pro Billet Cam Plate and Oil Pump. Screamin’ Eagle and Stage IV badging on the cylinder heads and timer cover highlights the powerplant.
Can be installed without removing the engine from chassis.
