132" Power Pack - 550 Gear Drive - Oil Cooled - Black Granite w/Highlight Fins - 114"/117" M8

Enhance your M8 engine's performance with the S&S Cycle 132" Power Pack Kit, designed to increase engine displacement from 114" or 117" to 132" without requiring case modifications. This bolt-in kit features a 4.5" stroke M8 crankshaft and 4.32" bore cylinders, combined with forged pistons that deliver an 11.0:1 compression ratio for optimal power output. The kit's precision components and engineering ensure a straightforward installation process, making it ideal for serious enthusiasts seeking significant performance upgrades.
Built with durability and efficiency in mind, the kit includes an S&S oil pump and cam plate with a sleek blue anodized finish, along with removable passage plugs for ease of servicing. Independent scavenge sections for the flywheel cavity and cam chest, along with debris screens in both scavenge pickups, help maintain clean oil flow and protect vital engine parts. A magnet in the cam chest further prevents debris from entering the oil pump, enhancing engine longevity. Increased oil flow capacity on both feed and scavenge sides ensures proper lubrication under high-performance conditions.
Designed for reliability and adjustability, the kit features an adjustable pressure relief valve that can be fine-tuned with the unit installed. It also includes quickee pushrods, premium S&S tappets with hard-anodized, black-coated cuffs, and S&S 550 cams tailored for big bore applications. The high-performance conical single wire valve springs support cams up to 0.605" lift, ensuring valve stability during aggressive operation. All necessary gaskets, bearings, and hardware are included for a seamless bolt-on installation. Made in the USA, this kit offers a robust upgrade for M8 engines, except for 121" CVO models, delivering increased power and durability in a sleek black granite finish with highlight fins.
