24400120 Crankcase for Milwaukee Eight

As Milwaukee Eight engines push into higher horsepower territories, the stock cases can struggle to keep up. These S&S crankcases provide a much stronger foundation for high-performance builds. They are engineered to accommodate larger bore sizes and feature improved oil scraping capabilities to keep the bottom end efficient. Despite the heavy-duty upgrades, they are designed to fit perfectly into the stock chassis of Touring and Trike models. These cases come ready for assembly with cylinder studs and crankshaft bearings already installed, and they include the necessary crankcase bolts and S&S high-performance piston cooling jets. They are an excellent high-strength alternative to OEM 24400120 for anyone building a serious long-distance or high-output M8 motor.
