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.

    • Question:
      5/25/2025
      Does this void the factory warranty?
      Donald - Florida
    • Question:
      5/19/2025
      What's the difference between the 92500144 kit and the 92500100 kit? Both say they fit 2024 Road Glide.
      Raym - US
      • Answer:
        One has the oil cooling fan and the other does not.
        • Answer:
          The heads are different from '24-25 and a bracket kit for the knock sensor doesn't resolve the fitment issue. For 2024, use the 92500100. For 2025, use the 92500144 kit only.
        • Answer:
          Hello Raym, This item is sold in store only. Please contact your local HD Dealership for assistance to better assist. Thanks
    • Question:
      2/14/2025
      What does labor typically cost for an install like this?
      Dustin - Colorado
      • Answer:
        The installation typically costs $2,000 to $ 2,500. I've had customers charged as much as $3000 for Work Change Orders and incidentals. Remember, you will need to have it Dyno tuned, which can run another $500 to $1,000.
    • Question:
      2/9/2025
      Will this fit a '24 street and/or road glide? I.e. would the new '25 heads with the knock sensor change fit the '24 touring bikes? Thanks!
      Kevin - Rochester, NY
      • Answer:
        Please purchase 92500100 if you have a '24 FLHX and FLTRX model. Purchasing 92500100 avoids the sold separately purchase of P/N 29900147 since it's not a '25-later model.
