Unleash the full potential of your Harley-Davidson M8 engine with the S&S Cycle Power Package Big Bore Kit 132".

Description
Experience a significant leap in power and torque with the S&S Cycle 132" Power Package Big Bore Kit, specifically engineered for Harley-Davidson M8 engines, including the VVT models. This bolt-on upgrade transforms your existing 114" or 117" M8 engine, pushing its displacement to an impressive 132" through a 4.50" stroke, all while retaining stock engine height and working seamlessly with stock crankcases. The kit features an updated profile for perfect fitment and includes the renowned S&S oil pump and cam plate, designed with independent scavenge sections for the flywheel cavity and cam chest to ensure optimal lubrication and debris management. Removable passage plugs allow for easy servicing, while a magnet in the cam chest and debris screens in scavenge pickups prevent harmful particles from entering the oil pump. Enjoy increased oil flow capacity on both the feed and scavenge sides, complemented by an adjustable pressure relief valve that can be fine-tuned even after installation. Performance is further enhanced by S&S Quickee pushrods with pushrod tubes, premium tappets, and billet aluminum, hard anodized, black coated tappet cuffs. The high-performance conical single-wire S&S valve springs are compatible with cams up to 0.605" lift, perfectly matched with the 496 cam, specifically designed for big bore applications. An MLS (multi-layered steel) head gasket ensures a reliable seal, and crucially, your original engine serial numbers are retained. Proudly Made in the USA, this kit is also compatible with both stock and S&S roller rocker arms, as well as both first and second-generation stock valve springs.
