Upgrade your M8 engine with the S&S CYCLE Cam Chest Kit, part number 310-1261, designed for improved performance and durability. Crafted from precision machined billet aluminum, the oil pump and cam plate offer a robust construction that ensures reliable lubrication and efficient oil flow. Features include removable passage plugs for ease of servicing, an independent scavenge section for the flywheel cavity and cam chest, and debris screens in both scavenge pickups. A magnet in the cam chest helps prevent debris from entering the oil pump, prolonging component life. This kit provides a 44% increase in flow on the supply side and a 58% enhancement on the scavenge side, promoting better oil circulation under high-performance conditions. The pressure relief valve is adjustable with the unit installed in the engine, allowing fine-tuning for optimal oil pressure. The Chrome Pushrods complement the kit, providing durability and aesthetic appeal, making them an ideal upgrade for your Harley-Davidson M8 engine. The kit also includes S&S Precision Tappets, which are hand assembled to exacting tolerances for consistent operation. These tappets reduce valvetrain noise from startup to shutdown, feature close tolerances for low leak-down rates, and deliver fast pump-up and high RPM performance. The billet aluminum tappet cuffs are hard anodized in black, offering increased strength over stock components, resisting distortion, and maintaining stability during high lift and high RPM situations. Made in the USA, this kit combines quality craftsmanship with performance enhancements, making it a reliable choice for serious riders seeking improved engine efficiency and durability.
