Description

Experience unparalleled engine performance and durability with the S&S Cycle M8 cam chest kit, a premium Milwaukee-Eight oil pump upgrade. The oil pump and cam plate are meticulously precision-machined from robust billet aluminum, then finished with a striking blue anodized coating for both aesthetics and corrosion resistance. This advanced design features independent scavenge sections for both the flywheel cavity and the cam chest, dramatically improving oil scavenging efficiency. Debris screens in both scavenge pickups provide an added layer of protection against contaminants, while increased oil flow capacity on both the feed and scavenge sides ensures optimal lubrication under all operating conditions. A key benefit is the adjustable pressure relief valve, which can be fine-tuned with the unit still installed in your engine, allowing for precise oil pressure management. The kit includes S&S premium tappets and stronger billet aluminum tappet cuffs, hard-anodized in black, which are engineered to eliminate distortion and enhance tappet stability, especially in high-lift cam applications. This performance cam chest assembly is proudly made in the USA and is compatible with M8 engines, including those equipped with VVT, making it a versatile chain drive cam kit for your Harley-Davidson.
