Description

Unleash extreme power and reliability with the S&S Cycle 132" Power Package, designed specifically for Milwaukee-Eight (M8) engines with a 4.50" stroke. This comprehensive kit boosts your 114" or 117" engine to a massive 132" displacement, providing a significant upgrade in torque and horsepower. The heart of this kit features robust 4.320" big bore cylinders paired with 11.0:1 forged pistons, ensuring exceptional durability and high compression for an aggressive power curve. The integrated S&S oil pump and cam plate system boasts independent scavenge sections for the flywheel cavity and cam chest, along with debris screens and a magnet in the cam chest, all designed to prevent contaminants and ensure optimal oil flow and engine longevity. An adjustable pressure relief valve allows for fine-tuning even after installation, providing precise control over your oil system. The kit includes S&S Quickee pushrods with chrome pushrod tubes and premium tappets for quick, reliable valvetrain operation. High-performance conical single wire S&S valve springs are compatible with cams up to 0.605" lift, perfectly complementing the included HPT496 cam, which is specifically engineered for big bore applications. A multi-layered steel (MLS) head gasket ensures a superior seal, while hard anodized, black coated billet aluminum tappet cuffs offer enhanced strength and a premium finish. Proudly made 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 your original engine serial numbers.
