For the rider demanding no-compromise performance. This 117ci to 131ci 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 131 horsepower and 139 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 Factory Racing Team for the King of the Baggers racing series. 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 and new patent-protected 4.31" steel sleeve cylinders. Screamin’ Eagle and Stage IV badging on the cylinder heads and timer cover highlights the powerplant.

      What is the difference between 92500100 and 92500144?
      Kevin - Rochester, NY
      • Answer:
        The fitment is the difference. 92500100 only fits '24 FLHX and FLTRX models due to cylinder head changes on '25-later models.

      Genuine Harley-Davidson Stage 4 M8 Touring Exhaust Header Pipe 65600177 - what is the difference between stock pipe
      Anton - Russia
      • Answer:
        Less back pressure and stock pipes are 2 into 2 vs 2 into 1. It might have a different sized bung hole for the 02 sensors not to mention bare metal pipe and no cat. That's my 2 cents.
