132" Power Package - HPT496 - Gear Drive - Oil Cooled - Balck with Highlights - 114"/117" M8
Enhance your M8 motorcycle with the S&S Cycle 132-inch Power Package (Part Number 310-1393), designed to provide significant performance upgrades without requiring case machining. This bolt-on kit extends your engine's displacement from 114 or 117 inches to 132 inches, delivering increased power and torque for a more exhilarating riding experience. The kit features a big bore 4.320-inch cylinder combined with 11.0:1 forged pistons, ensuring durability and high performance under demanding conditions. The inclusion of an S&S oil pump and cam plate optimizes oil flow and lubrication, while removable passage plugs facilitate easy servicing of key components. Independent scavenge sections for the flywheel cavity and cam chest, along with debris screens in both pickups, help maintain engine cleanliness and reliability. A magnet in the cam chest further prevents debris from entering the oil pump, extending engine longevity. The system's increased oil flow capacity on both feed and scavenge sides ensures optimal lubrication, even during high-performance operation. The adjustable pressure relief valve allows fine-tuning of oil pressure while the engine is in use, providing flexibility for various riding conditions. Quickee pushrods with pushrod tubes and S&S premium tappets facilitate installation and maintenance, while hard anodized, black-coated tappet cuffs made from billet aluminum add durability and a sleek appearance. S&S valve springs are compatible with cams up to 0.605-inch lift and feature a high-performance conical single wire spring design to support aggressive cam profiles. The HPT496 cam, specifically designed for big bore applications, delivers enhanced power and torque. Multi-layered steel (MLS) head gaskets ensure reliable sealing, and the package includes a 132-inch cam cover badge for authentic styling. Built in the USA, this kit retains stock engine height, works seamlessly with stock crankcases, and is compatible with both stock and S&S roller rocker arms, preserving the originality of your engine serial numbers. It also accommodates both first-generation (round port) and second-generation (oval port) stock valve springs, making it a versatile upgrade for your Harley-Davidson M8 engine.
