This S&S Cycle Power Pack is an updated profile kit for water-cooled Harley-Davidson Milwaukee-Eight (M8) engines from 2017 and newer. It features a 4.250" bore and 4-1/2" stroke. The kit includes a cam chain tensioner, chrome pushrod tubes, and a 550C cam, all finished in black with highlights. This gear-drive kit aims to improve engine performance through higher lift and optimized cam timing. It includes S&S Quickee pushrods for easier installation without removing rocker covers. The Power Pack replaces the stock oil pump, cam support plate, cams, chain tensioners, and tappets with new, premium U.S.-made S&S components.
