S&S Cycle 496 Series Cam Chest Kit

Upgrade your motorcycle's valvetrain and oiling system with the S&S Cycle 496 Series Cam Chest Kit. This comprehensive performance cam chest kit is engineered for superior durability and optimized engine performance, featuring precision-machined components and the renowned 496 grind cam.

Description

Experience unparalleled engine reliability and performance with this advanced cam chest kit, specifically designed for oil-cooled applications. The heart of this kit lies in its precision-machined billet aluminum oil pump and cam plate, ensuring exceptional strength and exact tolerances. It features independent scavenge sections for both the flywheel cavity and cam chest, optimizing oil return. To maintain oil purity and extend engine life, debris screens are integrated into both scavenge pickups, complemented by a magnet in the cam chest to capture metallic particles before they can enter the oil pump. Enjoy increased oil flow capacity on both the feed and scavenge sides, providing optimal lubrication under all operating conditions. The kit includes an updated oil pump with a groove for an optional OEM oil seal, and an adjustable pressure relief valve that can be fine-tuned even with the unit installed in your engine. The included Quickee pushrods facilitate easier installation, while the high-performance tappets offer fast pump-up and superior high-RPM performance, significantly reducing valvetrain noise from startup to shutdown thanks to their close tolerances. Further enhancing stability, the hard-anodized black tappet cuffs improve tappet stability in high lift and high RPM situations, making this 496 Series cam chest kit a robust upgrade for serious riders seeking the 0.485" intake/exhaust lift and 227° intake / 243° exhaust duration performance of the 496 grind.
