Harley Davidson Screamin Eagle 4.155″ Big Bore Bolt-On Cylinders Black/highlight

Increase the displacement of your Milwaukee-Eight engine without removing the engine from the chassis. The Screamin’ Eagle product team has engineered a patent protected 4.155″ Big Bore Cylinder that increases the internal bore but slips into the existing case bore without modification. When combined with the appropriate piston and flywheel combination in the Screamin’ Eagle Stage IV kits, these cylinders can increase the displacement of your Milwaukee-Eight engine from 107CI to 119CI or from 114CI & 117CI to 122CI.
