Description

Unleash extreme power and superior reliability with the S&S Cycle 128" Power Package, a meticulously designed performance upgrade for VVT engine kit motorcycles. This package features an updated profile and robust forged pistons, ensuring exceptional durability and strength under high-stress conditions. Proudly Made in the USA, every component reflects S&S Cycle's commitment to quality and precision engineering. The bolt-in design simplifies installation, requiring no case machining, which means less downtime and a quicker return to the road. At its core, this kit includes a high-performance S&S 550 camshaft, optimized for aggressive power delivery and high RPM stability. Complementing the camshaft are valve springs designed to work flawlessly with lifts up to 0.605", ensuring consistent valve train control.

The included oil pump and cam plate are precision machined from billet aluminum, featuring independent scavenge sections for the flywheel cavity and camchest, along with debris screens and a camchest magnet to protect your engine from harmful contaminants. This advanced design significantly increases oil flow capacity on both the feed and scavenge sides, while the adjustable pressure relief valve allows for fine-tuning even with the unit installed. Quickee pushrods and S&S premium tappets, coupled with hard-anodized, billet aluminum, black-coated tappet cuffs, further enhance valve train stability in high-lift and high-RPM situations. This comprehensive S&S Cycle performance upgrade is specifically engineered for VVT models, ensuring perfect compatibility and maximum performance gains.
