The demand for performance-based 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. This new version of the MK-Series Crankcases are ready for even more than the originals. These cases are designed to accept cylinders up to 4 1/2", which is massive! Like the originals, these cases scrape more oil than stock and offer more reliability, all without frame modifications.
Genuine S&S Cycle. Part number 310-1341.
Ships from US warehouse.
Note: Not CARB approved — not for sale or use on pollution-controlled vehicles in California.
