Power Pack - Oil Cooled - 550C - Wrinkle Black w/o Highlight - Chrome Pushrod Tubes - 114"/117" M8
The S&S Cycle Power Pack 550C oil-cooled kit is designed for high-performance Harley-Davidson M8 engines ranging from 114 to 117 inches, providing a significant boost in power without the need for case machining. This comprehensive kit features a big-bore bolt-in design with a 4.5-inch stroke, allowing you to increase your engine's displacement to 132 inches while maintaining a straightforward installation process. The updated profile and 4.32-inch bore cylinders combined with an 11.0:1 compression ratio forged pistons deliver increased horsepower and torque, making it ideal for riders seeking enhanced performance. The kit includes an S&S oil pump and cam plate with a stylish blue anodized finish, along with removable passage plugs for easy servicing. Independent scavenge sections for the flywheel cavity and cam chest improve oil flow and filtration efficiency. Debris screens in both scavenge pickups and a magnet in the cam chest work together to prevent debris from entering the oil pump, ensuring reliable operation. The increased oil flow capacity on both feed and scavenge sides enhances cooling and lubrication, supporting the demands of high-performance riding. An adjustable pressure relief valve allows fine-tuning of oil pressure while the engine is installed, offering added control. The kit also includes Quickee pushrods, S&S premium tappets, and hard-anodized, black-coated billet aluminum tappet cuffs, which are compatible with high-lift cams up to 0.605 inches. Designed for big bore applications, the S&S 550 cams optimize airflow and performance. The high-performance conical single-wire valve springs are engineered to work with the included cams, providing reliable valve operation. Made in the USA, this kit is compatible with VVT models but not suitable for trike configurations. Please note that intake and rocker cover gaskets are not included. Perfect for enthusiasts seeking a robust upgrade, the S&S Power Pack 550C ensures durability and increased power for your Harley-Davidson M8 engine.
