Description

Unleash the full potential of your Milwaukee-Eight engine with this meticulously engineered S&S Cycle 132 Power Package. Designed for a direct bolt-on installation, this Milwaukee-Eight big bore kit converts your 114" or 117" engine to a formidable 132" displacement, thanks to its precision 4.320" big bore cylinders and robust 11.0:1 forged pistons. The absence of case machining requirements simplifies installation, allowing you to achieve a substantial power increase with less downtime.

At the heart of this M8 132 power package is a complete S&S oil pump and cam plate system, featuring independent scavenge sections for the flywheel cavity and cam chest. Debris screens in both scavenge pickups and a magnet in the cam chest work together to prevent contaminants from entering the oil pump, ensuring superior engine protection and longevity. The system boasts increased oil flow capacity on both feed and scavenge sides, complemented by an adjustable pressure relief valve for precise control. Performance is further enhanced by the HPT496 cam, specifically designed for big bore applications, paired with Quickee pushrods, premium S&S tappets, and hard anodized, black-coated billet aluminum tappet cuffs. S&S valve springs, capable of handling cams up to 0.605" lift, complete this high-performance setup. This kit retains stock engine height, works with stock crankcases, and is compatible with both stock and S&S roller rocker arms, preserving your original engine serial numbers. Proudly Made in the USA, this kit delivers exceptional quality and a significant motorcycle engine upgrade.
