Description

The S&S Cycle 132" Power Package is a complete, bolt-in big bore kit designed to significantly increase the performance of your 114"/117" Milwaukee-Eight (M8) VVT engine with a 4.5" stroke. This kit brings your engine up to a formidable 132" displacement without requiring any complicated case machining, ensuring a straightforward installation process. At its core are high-performance 4.32" bore cylinders paired with robust 11.0:1 compression ratio forged pistons, providing the foundation for extreme power and reliability. An updated profile further optimizes engine dynamics for superior output.

Beyond the cylinders and pistons, this S&S Cycle 132" Power Package includes a meticulously engineered S&S oil pump and cam plate, finished in a striking blue anodized coating for both durability and aesthetics. This system features independent scavenge sections for the flywheel cavity and cam chest, along with debris screens in both scavenge pickups and a magnet in the cam chest to help prevent debris from entering the oil pump, ensuring optimal oil flow and engine longevity. The adjustable pressure relief valve can be fine-tuned even with the unit installed. Complementing these components are S&S 550 cams, specifically designed for big bore applications, paired with Quickee pushrods, premium tappets, and hard-anodized, black-coated billet aluminum tappet cuffs. High-performance conical single wire valve springs, capable of handling cams up to 0.605" lift, complete the package, all proudly made in the USA for superior quality.
