Description

The S&S Cycle 132" Power Package delivers an unparalleled upgrade, meticulously designed to elevate your riding experience. At its core, this kit features big bore 4.320" cylinders paired with robust 11.0:1 forged pistons, providing the foundation for incredible power and torque. The comprehensive package includes an advanced S&S oil pump and cam plate system, boasting independent scavenge sections for both the flywheel cavity and cam chest, ensuring optimal oil management. Debris screens in both scavenge pickups and a strategically placed magnet in the cam chest work to prevent contaminants from entering the oil pump, extending engine life and maintaining peak performance. With increased oil flow capacity on both the feed and scavenge sides, your engine receives superior lubrication under all conditions. An adjustable pressure relief valve allows for fine-tuning even after installation, providing customized oil pressure control.

Further enhancing this motorcycle performance kit are S&S Quickee pushrods with pushrod tubes, S&S premium tappets, and durable hard-anodized, black-coated billet aluminum tappet cuffs. The included S&S valve springs feature a high-performance conical single-wire design, compatible with cams up to 0.605" lift, and are paired with the specially designed HPT496 cam for big bore applications. An MLS (multi-layered steel) head gasket ensures a reliable seal. This Harley-Davidson M8 big bore kit is proudly Made in the USA, retains stock engine height, works seamlessly with stock crankcases and both stock and S&S roller rocker arms, and preserves your original engine serial numbers, making it a truly integrated and high-quality 114" to 132" engine upgrade.
