Screamin' Eagle 4.310 In. Big Bore Bolt-On Cylinders
Increase the displacement of your Milwaukee-Eight® engine without removing the engine from the chassis. The Screamin’ Eagle® team has engineered a patent-protected 4.310” 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 128CI or a 114CI & 117CI to 131CI.
- Replacement cylinders for '17-later Milwaukee-Eight® models equipped with 128 or 131CI Stage IV kits
- Kit includes front and rear cylinders and gaskets
