S&S Cycle Cam Chest Kit for Harley-Davidson M8

Elevate the performance and reliability of your Harley-Davidson Milwaukee-Eight (M8) engine with the advanced S&S Cycle Cam Chest Kit. This comprehensive upgrade is engineered to deliver superior oiling, enhanced valvetrain stability, and increased durability for demanding riding conditions.

Description

Designed for the modern M8 engine, this high-performance cam chest kit features a precision-machined oil pump and cam plate, both crafted from robust billet aluminum and finished with a distinctive blue anodized coating. This construction ensures exceptional strength and longevity, far surpassing stock components. The kit significantly boosts oil flow capacity on both the feed and scavenge sides, crucial for maintaining optimal lubrication and cooling, especially under high RPMs. Innovative independent scavenge sections for the flywheel cavity and cam chest, complete with debris screens, ensure a cleaner oil supply and prevent contamination. Riders will appreciate the adjustable pressure relief valve, which can be fine-tuned even after installation, allowing for precise oil pressure management. The kit also includes S&S premium tappets and billet aluminum tappet cuffs, hard-anodized black for enhanced durability. These cuffs are stronger than stock, effectively eliminating distortion and improving tappet stability in high-lift situations, critical for the included 475C grind cam. This complete chain drive cam chest kit is specifically designed for water-cooled M8 applications, including those with VVT, and is proudly Made in the USA, featuring stylish black pushrod tubes.
