Description

The S&S Cycle Cam Chest Kit for M8 engines is a comprehensive upgrade designed to optimize your engine's internal workings. At its core, the performance oil pump and cam plate are precision-machined from robust billet aluminum, then finished with a striking blue anodization for both protection and aesthetics. This superior construction ensures exceptional strength and longevity, far surpassing stock components. The innovative design features independent scavenge sections for the flywheel cavity and cam chest, significantly increasing oil flow capacity on both feed and scavenge sides. Debris screens in both scavenge pickups provide critical protection against contaminants, while removable passage plugs simplify servicing. An adjustable pressure relief valve allows for fine-tuning oil pressure, even with the unit installed in the engine. This chain drive cam kit includes S&S premium tappets and stronger billet aluminum tappet cuffs with a hard-anodized black coating, which eliminate distortion and improve tappet stability, especially crucial in high-lift situations. Designed for Harley-Davidson Milwaukee-Eight cam plate applications, this kit is compatible with M8 engines featuring VVT and is specifically engineered for oil-cooled setups, providing the renowned S&S 475C cam grind for impressive power gains. Proudly made in the USA, this kit also includes a cam chain tensioner, making it a complete M8 engine upgrade solution.
