Unleash the full potential of your Harley-Davidson Milwaukee-Eight engine with the S&S Cycle Power Pack VVT 129 Engine Performance Kit.

Description

The S&S Cycle M8 129 Engine Performance Kit is meticulously designed for motorcycle enthusiasts seeking a substantial upgrade for their Milwaukee-Eight models, including those equipped with Variable Valve Timing (VVT). This kit features an updated profile for perfect fitment, ensuring a seamless installation process. At its core is the advanced S&S oil pump and cam plate, engineered with independent scavenge sections for both the flywheel cavity and cam chest, optimizing oil return and engine health. Debris screens in both scavenge pickups, along with a magnet in the cam chest, actively prevent contaminants from entering the oil pump, enhancing longevity and reliability. Experience increased oil flow capacity on both the feed and scavenge sides, ensuring consistent lubrication under demanding conditions. An adjustable pressure relief valve allows for fine-tuning of oil pressure, even after the unit is installed in the engine. The kit includes S&S Quickee pushrods with pushrod tubes, S&S premium tappets, and hard-anodized, black-coated billet aluminum tappet cuffs for superior durability. High-performance conical single wire S&S valve springs are included, compatible with cams up to 0.605" lift. A robust MLS (multi-layered steel) head gasket ensures a tight seal, while the performance-oriented 496 camshaft delivers improved power delivery. Proudly made in the USA, this kit retains stock engine height and is fully compatible with stock crankcases, stock and S&S roller rocker arms, and both first and second-generation stock valve springs.
