Increase the displacement of your Milwaukee-Eight® engine without removing the engine from the chassis. The Screamin’ Eagle product team has engineered a 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 combination in the Screamin’ Eagle® Stage III kit, these cylinders can increase the displacement of your Milwaukee-Eight engine from 121CI to 125CI.
