Enhance your M8 engine with the S&S Cycle 132" Power Pack, designed for exceptional performance and reliability. This bolt-in kit increases engine displacement from 114 or 117 inches to 132 inches without the need for case machining, making it a straightforward upgrade for serious riders. The kit features 4.32-inch bore cylinders paired with forged pistons that provide an 11.0:1 compression ratio, ensuring optimal power output and durability. Its premium components include an S&S oil pump and cam plate finished in blue anodized aluminum, along with removable passage plugs for easy servicing. Independent scavenge sections for the flywheel cavity and cam chest improve oil flow and help prevent debris buildup, with debris screens in both scavenge pickups and a magnet in the cam chest to further protect the oil pump from contaminants. The increased oil flow capacity on both feed and scavenge sides enhances cooling and lubrication, supporting the engine's high-performance demands. The kit incorporates an adjustable pressure relief valve that can be fine-tuned with the unit installed, providing precise oil pressure management. Quickee pushrods, S&S premium tappets, and hard-anodized, black-coated tappet cuffs made of billet aluminum contribute to durability and smooth operation. Designed for big bore applications, the S&S 550 cams work effectively with valve springs up to 0.605 inches lift, utilizing high-performance conical single wire springs for reliable valve control. Included gaskets—exhaust, cylinder base, and head—ensure proper sealing during installation. Made in the USA, this power pack is specifically not compatible with 121-inch CVO or Trike models, offering a reliable upgrade for M8 owners seeking increased displacement and performance. The Wrinkle Black finish with highlight fins adds a sleek aesthetic touch, complementing your engine's visual appeal.
