Description

The S&S Cycle 132" Power Package delivers a significant performance upgrade for M8 VVT models, dramatically increasing displacement from 114"/117" to an impressive 132" with its 4.5" stroke compatibility. At its core are precision-machined 4.32" bore cylinders paired with durable 11.0:1 compression forged pistons, designed to provide a substantial boost in horsepower and torque. This kit features an updated profile for optimal engine dynamics. The advanced S&S oil pump and cam plate, finished with a distinctive blue anodized coating, ensure superior lubrication. It boasts independent scavenge sections for both the flywheel cavity and cam chest, along with debris screens in both scavenge pickups and a magnet in the cam chest to protect the oil pump from harmful contaminants. With increased oil flow capacity on both the feed and scavenge sides, your engine receives consistent, high-volume lubrication. An adjustable pressure relief valve allows for fine-tuning even when the unit is installed. Further enhancing the valvetrain are Quickee pushrods, S&S premium tappets, and robust hard-anodized, black-coated billet aluminum tappet cuffs. The package includes S&S 550 cams, specifically engineered for big bore applications, and S&S valve springs that support cams with up to 0.605" lift, featuring a high-performance conical single wire design. Proudly Made in the USA, this kit is designed for VVT models, ensuring perfect compatibility and peak performance.
