S&S, M8 Softail MK-Series crankcase assembly

The demand for performance-based Softail parts is growing, and like with M8 Touring engines, it seems they are creating more power daily. All that power requires a quality and strength that stock cases just can't provide. That's where the new S&S M8 'B' (balanced) crankcases come in. Designed to allow for larger bores, with a machined oil scraper for less oil on the flywheels. Offered is better reliability, all while fitting in a stock Softail frame.
