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.
