Install requires machining to be performed by a competent machinist using the Screamin Eagle® Automatic Compression Release Fixture Kit P/N 94648-08 (sold separately)
Installation requires separate purchase of model specific ACR Wiring Harness


Fitment: Fits 07-17 Twin Cam-equipped models. Can be used with Original Equipment or Screamin Eagle® Cylinder Heads. Does not fit with Twin-Cooled™ engines.
