132" Power Pack - 550 Gear Drive - Oil Cooled - Black w/o Highlight Fins - 114"/117" M8

Upgrade your M8 engine with the S&S Cycle 132 Inch Power Pack, designed specifically for 114" and 117" engine configurations. This comprehensive bolt-in kit increases engine displacement from 114"/117" to 132" without requiring case machining, providing a significant boost in power and performance. The kit features a 4.32" bore cylinder set with forged pistons and an 11.0:1 compression ratio, ensuring durability and high performance under demanding conditions. The included S&S oil pump and cam plate with a sleek blue anodized finish enhance oil flow and engine longevity, while removable passage plugs facilitate routine servicing. Independent scavenge sections for the flywheel cavity and cam chest, along with debris screens in both pickups and a magnet in the cam chest, help prevent contaminants from entering critical oil passages, maintaining clean oil circulation. The increased oil flow capacity on both feed and scavenging sides further supports high-performance operation. The kit incorporates an adjustable pressure relief valve, allowing for precise oil pressure regulation when installed in the engine. Quickee pushrods, S&S premium tappets, and hard-anodized, black-coated tappet cuffs made from billet aluminum contribute to reliable valvetrain operation. Designed for big bore applications, the S&S 550 cams work seamlessly with valve springs capable of up to 0.605" lift, utilizing a high-performance conical single wire spring design. All necessary gaskets, bearings, and hardware are included for straightforward bolt-on installation. This product is proudly made in the USA and is not compatible with 121" CVO models. Elevate your motorcycle's performance with this powerful, durable, and expertly engineered upgrade from S&S Cycle.
