Description
The S&S Cycle 132" Power Package is a meticulously engineered M8 engine upgrade, designed to maximize the potential of your Harley-Davidson Milwaukee-Eight. At its core are high-performance 4.32" bore cylinders paired with 11.0:1 compression ratio forged pistons, ensuring robust power delivery and enhanced throttle response. This kit features an updated profile for optimal performance and a seamless bolt-in installation, eliminating the need for costly and time-consuming case machining.
Beyond the impressive displacement, this power package integrates a sophisticated S&S oil pump and cam plate, finished with a distinctive blue anodized coating. This advanced oiling system boasts independent scavenge sections for both the flywheel cavity and cam chest, ensuring superior oil return and lubrication. Integrated debris screens in both scavenge pickups and a magnet in the cam chest prevent contaminants from reaching critical engine components, significantly increasing engine longevity and reliability. With increased oil flow capacity on both the feed and scavenge sides, coupled with an adjustable pressure relief valve that can be serviced with the unit installed, your engine receives optimal lubrication under all conditions. The kit also includes S&S Quickee pushrods, premium tappets, and hard-anodized, black-coated billet aluminum tappet cuffs for a durable and precise valvetrain. Power is further enhanced by S&S 550 cams, specifically designed for big bore applications, and high-performance conical single wire valve springs capable of handling cam lifts up to 0.605". Proudly Made in the USA, this kit delivers proven performance and S&S Cycle's legendary quality, making it the ultimate Milwaukee-Eight performance upgrade.
