Description

The S&S Cycle Gear Drive Cam Chest Kit is a complete performance upgrade designed specifically for Milwaukee-Eight models, including those with VVT. At its core, this kit replaces the factory cam chain tensioner with a robust gear drive system, ensuring precise cam timing for optimal power delivery and engine efficiency. Each component, from the precision-machined billet aluminum oil pump and cam plate with their striking blue anodized finish, to the hard-anodized black billet aluminum tappet cuffs, is crafted for superior quality, fit, and performance. Riders will experience improved tappet stability even in high-lift and high-RPM situations, thanks to the stronger-than-stock tappet cuffs that resist distortion. The innovative oiling system features independent scavenge sections for the flywheel cavity and cam chest, along with debris screens in both scavenge pickups and increased oil flow capacity on both the feed and scavenge sides. An adjustable pressure relief valve allows for fine-tuning even after installation. Complete with S&S Quickee Pushrods with finished tubes and S&S premium tappets, this Made in the USA kit provides a comprehensive solution for enhancing your M8's engine reliability and power.
