S&S MK-Series Crankcase for 2017-up Milwaukee Eight Touring Models

DECEMBER 2023: The demand for performance-based bagger parts is growing, and these M8 engines are creating more power daily. All that power requires a quality base that the stock cases can’t provide.

That’s where the new S&S MK-Series Crankcases come in!

We designed these cases to allow for larger bores than stock while also reinforcing them to prevent cracking in high-stress areas. They feature a machined, close-fitting oil scraper and a larger oil sump that allows the engine to scavenge more oil creating lower oil temperatures.

All this results in a finished piece that is made in the USA, more reliable than stock, and still retains the stock deck height, so there are no clearance issues in your stock touring frames.
